Description

The present invention relates to a power supply system, a power supply method, and a power supply program using renewable energy generating equipment. Specifically, the present invention relates to a power supply system, a power supply method, and a power supply program in which consumers trade the amount of power generated by a power generation facility that uses renewable energy installed in a remote location.

Although it is true that the amount of electricity generated from renewable energy such as solar power generation is increasing because it has the advantage of not having an environmental impact, the potential for its introduction is limited due to issues with stable supply and cost. The reality is that the actual amount introduced is small compared to the current situation, and various efforts are being considered to promote introduction.

For example, it has been proposed to provide a power supply system using renewable energy power generation equipment that makes it possible to stably supply off-grid power even in areas where there is no existing power generation equipment ( For example, Patent Document 1).

In addition, for example, a business operator provides the information necessary to select a solar cell, receives funding from an investor, installs a power generation system using the solar cell selected by the investor, and then provides the investor with the amount of funds. The proposal is to issue securities that meet the above criteria, and if profits are made from power generation through the operation of the power generation system, dividends will be refunded to investors in accordance with the profits, and the securities will be traded on the market. (For example, Patent Document 2).

Here, various government subsidy systems and high-priced purchase systems are applied to electricity generated with renewable energy, but with new household installations, these purchase prices are decreasing, and the purchase price is decreasing. The period is also shorter for residential use than for business use, reducing the benefits especially for small-scale customers.

In addition, some consumers who live in small houses, multi-family housing (condominiums, apartment complexes, etc.), and areas with low renewable energy potential (low solar radiation, bad wind conditions, etc.) are unable to choose their location even if their environmental awareness increases. Due to the above constraints, it is assumed that there are many consumers who are unable to introduce renewable energy even if they want to.

In the conventional technology described in Patent Document 1, if the initial investment cost of power generation equipment using renewable energy becomes large, a business operator cannot easily invest in it from the viewpoint of profitability. Furthermore, in the conventional technology described in Patent Document 1, only the customers in the vicinity where renewable energy power generation facilities are installed are targeted, and even if they want to introduce renewable energy due to locational constraints such as apartment complexes, they cannot introduce it. It is not possible to take advantage of customers who are unable to do so.

In addition, in the conventional technology described in Patent Document 2, securities are issued to investors according to the amount of capital invested and are traded in the market, and although the amount of power generation is disclosed in real time, It is made public for the purpose of securities trading, and investors cannot confirm the amount of power generated without going to the trouble of accessing it.

The present invention can reduce the initial investment cost of power generation equipment that uses renewable energy, allows anyone to purchase and participate in renewable energy, and promotes the utilization of renewable energy.

It is for.

Consumer B is a person who resides outside the area to which the remote power generation facility 30 supplies the power generated, but within the area to which the business operator A's neighboring power generation facility 20 supplies the power. Of course, the residential area of consumer B is not limited to the above-mentioned area, and may be located within the area supplied with the electric power generated by the remote power generation facility 30, for example.

Consumer B has a consumer-side terminal 60 for displaying information from the billing server 40, and a consumer-side measurement device for measuring the amount of power consumed by consumer B supplied from the nearby power generation facility 20. A device 70 is provided.

The consumer side terminal 60 displays the measurement result of information regarding the power consumption of consumer B on the consumer side measuring device 70, and the part corresponding to the installed capacity invested by the consumer on the power generation equipment side measuring device 32. It is set to be able to display the measurement results of information regarding the amount of power generated by the system at the same time.
Of course, the display is not limited to "simultaneously displayed", and there may be a time difference, and the display may be made to be displayed individually depending on the customer's selection operation.

Specifically, the consumer side measuring device 70 measures the current current value (ampere) of the power consumed by consumer B and the power consumption at predetermined time intervals (for example, every 30 minutes, every 60 minutes, etc.). This includes so-called smart meters, which are high-performance electricity meters with information and communication functions that can digitally measure electricity.

The consumer-side measuring device 70 of the consumer B notifies the consumer-side terminal 60 of information regarding the power consumption of the consumer B measured by the consumer-side measuring device 70 in real time. Information on the power consumption of customer B is displayed on the customer side terminal 60 in real time.
Further, the consumer-side measuring device 70 of consumer B transmits information regarding the power consumption of consumer B measured by the consumer-side measuring device 70 to the expense billing server 40 of business operator A in real time. . Information regarding the power consumption of consumer B is calculated and processed by the billing server 40 in real time.

The customer side terminal 60 of the customer B receives a portion of the remote power generation equipment 30 corresponding to the equipment capacity invested by the customer B from the server communication device 43 of the information providing means 50 (described later) of the expense billing server 40 of the business operator A. Various information (data) regarding the amount of power generated by the consumer is transmitted in real time via a network line and displayed in the form of a graph or the like on the consumer side terminal 60. Thereby, the various information concerned is notified to the consumer B.
The above-mentioned various information is transmitted to the consumer terminal 60, and the billing server 40 directly or the consumer terminal 60 transmits the information to a smartphone on which application software that operates on a mobile terminal such as a smartphone is installed. The information may be transmitted and displayed via the .

Consumer B can invest in a predetermined amount of installed capacity of the remote power generation equipment 30 for a predetermined period from the consumer terminal 60 based on various information sent from the expense billing server 40. It is.
The "predetermined period" is a predetermined time unit, and includes a predetermined year, month, day, day of the week, time, and a combination thereof. For example, this includes the hours from 10:00 to 15:00 from Monday to Friday in July of this year. Furthermore, the term "predetermined amount" refers to a predetermined numerical value (kW) such as the amount of power that can be generated by one solar power generation panel out of the entire installed capacity.

Consumer B is supplied with power from a nearby power generation facility 20 that can supply power to the area where consumer B resides. The power consumption of customer B is determined by the fact that customer B, who lives outside the area to which the remote power generation equipment 30 supplies the power, consumes power generated by a neighboring power generation equipment 20 that is different from the remote power generation equipment 30. will be accounted for.

The cost billing server 40 bills the consumer B for the amount of power consumed by the consumer B from the power supplied from the nearby power generation facility 20. At this time, the amount of power consumption for which the cost is billed takes into consideration the amount of power generated according to the installed capacity of the remote power generation facility 30 in which consumer B has invested.
Specifically, in the cost billing process, the cost billing server 40 determines, based on the power consumption of consumer B, using the arithmetic processing unit 54 (described later), that a portion of the remote power generation equipment 30 corresponding to the installed capacity invested by consumer B has generated electricity. Calculate the rate you will be charged by subtracting the amount of electricity generated.
At this time, if the unit price of electricity is set uniformly without fluctuation, the arithmetic processing unit 54 of the expense billing server 40, which will be described later, calculates the amount of electricity consumed by customer B from the cumulative value of electricity consumption in the billing period. , the billing amount is calculated based on the value obtained by subtracting the integrated value of the amount of power generated by the portion of the remote power generation equipment 30 that corresponds to the equipment capacity invested by the consumer B.

In addition, when the unit price of electricity is set to fluctuate every predetermined period, the arithmetic processing unit 54 of the expense billing server 40, which will be described later, updates the unit price of the customer B during the predetermined period for each predetermined period. Charges are calculated based on the integrated value of power consumption, minus the integrated value of the amount of power generated by the portion of the remote power generation equipment 30 that corresponds to the equipment capacity invested by consumer B, and the calculated charge is The total will be the billed amount.
Note that if the power rate system where the nearby power generation facility 20 is installed and the power rate system where the remote power generation facility 30 is installed are different, charges are calculated separately for each power rate system.

Here, the arithmetic processing unit 54 of the expense billing server 40, which will be described later, determines that when the amount of power generated by the portion of the remote power generation equipment 30 corresponding to the equipment capacity invested by the consumer B is less than the power consumption of the consumer B, In this step, the amount of power generated by the portion corresponding to the installed capacity invested by consumer B is subtracted from the power consumption of consumer B to calculate the fee to be charged to consumer B.

On the other hand, when the amount of power generated by the portion of the remote power generation equipment 30 corresponding to the equipment capacity invested by customer B exceeds the amount of power consumed by customer B, the arithmetic processing unit 54 of the expense billing server 40 will , it is possible to give benefits to consumer B for the excess amount. Specifically, this benefit is, for example, a point, which can be exchanged for products, services, etc. sold by business operator A by accumulating a predetermined number of points. This product may include electricity sold by business operator A, cash, and ancillary services such as a minimum amount of power generation. The above-mentioned benefits may also be so-called environmental value, which is the value of reducing the burden on the environment. Specifically, the amount of power generated in excess of the amount described above is converted into a green power certificate and transferred to consumer B as environmental value. Consumer B can obtain the benefit of being able to earn a profit by selling the green power certificate to a third party as environmental value.

In addition, in the procedure for calculating the billed amount as described above, the power generated by the portion of the remote power generation equipment 30 that corresponds to the equipment capacity invested by consumer B is "subtracted" from the power consumption of consumer B. However, the calculation procedure is not limited to this. Specifically, for example, the target to be "subtracted" is not "power consumption" or "power generation" but "amount of money" such as "amount of money according to power consumption" or "amount of money according to power generation". The converted values may be subjected to "subtraction".
Specifically, in the expense billing, the expense billing server 40 uses the arithmetic processing unit 54 (described later) to calculate the amount corresponding to the equipment capacity invested by the consumer B of the remote power generation facility 30 from the amount corresponding to the power consumption of the consumer B. The charge to be billed may be calculated by subtracting an amount corresponding to the amount of power generated by the part that generates electricity.
At this time, if the unit price of electricity is set uniformly without fluctuation, the arithmetic processing unit 54 (described later) of the expense billing server 40 calculates the integrated value of the electricity consumption of customer B during the expense billing period. The billing amount is calculated based on the amount obtained by multiplying the unit price by the amount obtained by multiplying the integrated value of the amount of power generated by the portion of the remote power generation equipment 30 that corresponds to the equipment capacity invested by consumer B by the unit price. do.
In addition, when the unit price of electricity is set to fluctuate every predetermined period, the arithmetic processing unit 54 of the expense billing server 40, which will be described later, updates the unit price of the customer B during the predetermined period for each predetermined period. The amount obtained by multiplying the unit price by the integrated value of the amount of power generated by the portion of the remote power generation equipment 30 that corresponds to the equipment capacity invested by consumer B is subtracted from the amount obtained by multiplying the integrated value of power consumption by the unit price. The charges may be calculated based on the above, and the total of the calculated charges may be the billed amount.
Note that if the power rate system where the nearby power generation facility 20 is installed and the power rate system where the remote power generation facility 30 is installed are different, charges are calculated separately for each power rate system.

Similarly, the arithmetic processing unit 54 (described later) of the expense billing server 40 determines that the amount of power generated by the portion of the remote power generation equipment 30 corresponding to the equipment capacity invested by customer B is less than or equal to the power consumption of customer B. In this case, calculate the fee to be charged to customer B by subtracting the amount corresponding to the amount of power generated by the portion corresponding to the installed capacity invested by customer B from the amount corresponding to the amount of electricity consumed by customer B. do. In other words, if the amount of electricity generated by the portion of the remote power generation equipment 30 that corresponds to the installed capacity invested by consumer B is sold is less than the amount of electricity consumed by consumer B, then Consumer B will be billed the difference obtained by subtracting the electricity price obtained by the amount of power generated by the portion corresponding to the installed capacity invested by consumer B from the electricity price for the amount of consumption.

On the other hand, the arithmetic processing unit 54 of the expense billing server 40, which will be described later, determines that the amount of money corresponding to the amount of power generated by the portion of the remote power generation equipment 30 corresponding to the equipment capacity invested by the customer B is the amount of electricity consumed by the customer B. If the amount exceeds the amount according to the above amount, it may be possible to give benefits to consumer B for the amount exceeding the amount. Here, this "privilege" has the same content as explained above.

In addition, as described above, if the amount of power generated by the portion of the remote power generation equipment 30 corresponding to the equipment capacity invested by customer B exceeds the power consumption of customer B, the "excess amount" is returned to customer B. Instead of awarding points as benefits, benefits such as points may be provided for the total amount of power generated by the portion of the remote power generation equipment 30 that corresponds to the equipment capacity invested by consumer B.
Alternatively, the entire amount of power generated by the portion of the remote power generation equipment 30 corresponding to the equipment capacity invested by consumer B may be converted into a green power certificate and transferred to consumer B as environmental value. That is, the expense billing server 40 may trade environmental value corresponding to the power generation amount of the invested equipment capacity instead of electricity as a transaction object between business operator A and consumer B.

As mentioned above, without using points or the like as an intermediary, the amount of electricity generated by the part of the remote power generation equipment 30 that corresponds to the installed capacity invested by consumer B is sold, which is the amount of electricity consumed by consumer B. If the amount exceeds the amount, the difference may be paid directly to customer B.

In this embodiment described above, the payment of electricity charges, the payment of the difference in charges as described above, and the delivery of investment fees, etc., between business operator A and consumer B are made using electronic money, etc. via a network line. This is made possible through electronic payments. Specifically, in order to exchange money between the expense billing server 40 and the consumer side terminal 60 of consumer B, the program of the expense billing server 40 includes the consumer terminal 60 of consumer B. 60, it is possible to connect to the online system of the bank where consumer B has an account, and it is possible to perform electronic payment.

Note that payment is not limited to electronic payment such as electronic money via the network line as described above, and may be performed by other means such as bank transfer. For example, when customer B delivers investment proceeds, customer B transfers the amount to business operator A's account by bank transfer, and business operator A pays customer B cash as a benefit. A may transfer cash to customer B's account by bank transfer. At this time, a method may be adopted in which the expense billing server 40 instructs the business operator A to transfer the expense to the customer B's account via a human being. Alternatively, a combination of cash transactions may be used, such as electronic payment for one side and bank transfer for the other.

FIG. 5 is a flowchart illustrating an example of the process of purchasing the installed capacity of the remote power generation facility 30 in the power supply system 10 and the flow after purchasing.

In the power supply system 10 in this embodiment, the power supply program is stored in advance in the ROM 44B of the expense billing server 40. The CPU 44A reads the power supply program stored in the ROM 44B and executes the power supply process.

Note that information on the remote power generation facility 30 and information on the consumer B are stored in the nonvolatile memory 44D. Further, the reception results of information regarding the amount of power generation transmitted from the remote transmission device 33 of the remote power generation facility 30 are also stored in the nonvolatile memory 44D each time. Note that if there are multiple remote power generation facilities 30 and multiple consumers, their data is also stored.

First, in step 110, information transmission processing is performed from the operator A side to the customer B. Specifically, information regarding the installed capacity of the remote power generation facility 30 and various weather data of the remote power generation facility 30 are transmitted. Note that this weather data includes past data, current data, and future predicted data based on weather forecasts. Then, the process advances to the next step 111.

In step 111, it is determined whether there is an investment request for a predetermined capacity of the remote power generation equipment 30 from the consumer B side. If it is determined that there has been an investment in the installed capacity of the remote power generation facility 30 from the consumer B side, the process proceeds to the next step 112, and if it is determined that there has been no such investment request, the process returns to before step 110.

In step 112, it is determined whether or not the business operator A has approved the investment request of customer B. If it is determined that the approval has been given, the process proceeds to the next step 113, and if it is determined that the approval has not been given, the process returns to step 112.

In step 113, the expense billing server 40 performs contract establishment processing. Specifically, the power generation equipment side measurement device 32 is set so as to be able to measure information regarding the amount of power generated by a portion corresponding to the installed capacity of the remote power generation equipment 30 for a predetermined period in which consumer B has invested; Data in the program is set so that various information can be automatically transmitted to consumer B, and information regarding the establishment of a contract is transmitted to consumer side terminal 60 of consumer B. Then, the process proceeds to the next step 114.

In step 114, processing is performed during the contract period. Note that the contents of this step will be explained in detail later (see FIG. 6). Then, the process advances to the next step 115.
In step 115, the integrated value of the amount of electricity generated by the portion of the remote power generation equipment 30 corresponding to the equipment capacity invested by consumer B during a predetermined period determined by the contract, and the amount of electricity consumed by consumer B during the period are determined. Arithmetic processing is performed to calculate the difference between the calculated power amount and the power amount.
Specifically, for example, if consumer B invests in the remote power generation equipment 30 for a predetermined installed capacity for the period from 11:00 to 16:00 from Monday to Friday in August of this year. , the amount of power generated by the portion of the remote power generation equipment 30 corresponding to the predetermined facility capacity during the period from 11:00 to 16:00 from Monday to Friday in August of this year, and the amount of power generated by customer B for the entire month of August of this year. Arithmetic processing is performed to calculate the difference between the amount of electricity consumed during the period and the amount of electricity consumed. Note that the calculation method of the calculation process and the period to be calculated are not limited to those described above. Then, the process proceeds to the next step 116.

In step 116, the expense billing server 40 performs billing processing based on the difference in power amount. Specifically, when the amount of power generation is less than the amount of electricity consumed by customer B, a process is performed in which a fee is calculated based on the difference in the amount of power and the fee is billed from business operator A to customer B. . On the other hand, when the amount of power generation exceeds the amount of power consumed by customer B, a process is performed in which a benefit is given to customer B for the excess amount based on the difference in the amount of power. Then, the process ends.

FIG. 6 is a flowchart illustrating an example of the flow of processing during the contract period in the power supply system 10.

In step 210, the expense billing server 40 determines whether it is the contract period date for consumer B's investment. Specifically, for example, if customer B has an investment contract for a predetermined facility capacity for a one-month period only in August of a predetermined year, It is determined whether the date falls within any of the 1st to 31st days. If it is determined that it is the contract period date for consumer B's investment, the process proceeds to the next step 211, and if it is determined that it is not the contract period day, the process ends.

In step 211, the expense billing server 40 determines whether or not the contract period for consumer B's investment is in progress. Specifically, for example, in the above example, consumer B invests in a predetermined equipment capacity for only 5 hours from 11:00 to 16:00 on a predetermined period of a predetermined year (August 1st to 31st). In the case where a contract has been made, it is determined whether the current time is the relevant time (from 11:00 to 16:00). If it is determined that it is during the contracted time, the process proceeds to the next step 212, and if it is determined that it is not during the contracted time, the process returns to step 210.
In this embodiment, as described above, only the contract period date and contract time are displayed, but the contract is not limited to this. The information may be displayed before and after the period, and the information may be displayed at all times regardless of the contract period.

In step 212, the power generation equipment side measurement device 32 performs measurement processing such as information regarding the amount of power generation corresponding to the equipment capacity invested by consumer B, and these measurement results are transmitted from the remote transmission device 33 to the billing server. 40. Here, the "information regarding the amount of power generation" includes the current power generation. Note that the information may include the amount of power generated on that day, the amount of power generated in that week, the amount of power generated in that month, and the like. Further, the information may include various meteorological data such as solar radiation, temperature, humidity, atmospheric pressure, wind speed, and wind direction measured by other measuring devices. Then, the process advances to the next step 213.

In step 213, the server communication device 43 transmits measurement results such as information regarding the amount of power generation to the consumer side terminal 60 of consumer B. Then, the process advances to the next step 214.

In step 214, the consumer-side measuring device 70 of consumer B performs measurement processing of information regarding the power consumption of consumer B, and the like. This "information regarding the power consumption of customer B" includes the current power consumption of customer B. Note that the information may include the power consumption of the day, the power consumption of the week, the power consumption of the month, and the like. Then, the process advances to the next step 215.

In step 215, on the consumer side, the measurement results such as information regarding the amount of power generation of the part of the remote power generation equipment 30 corresponding to the equipment capacity invested by consumer B and the measurement results such as information regarding the power consumption of consumer B are determined on the consumer side. Display processing on the terminal 60 is performed.
Specifically, for example, the current power generation output of the portion of the remote power generation equipment 30 corresponding to the equipment capacity invested by the consumer B and the current power consumption of the consumer B can be compared with the consumer side terminal 60. Contains what is shown.
Further, for example, today's power generation amount of the portion of the remote power generation equipment 30 corresponding to the equipment capacity invested by consumer B and today's power consumption of consumer B are displayed on the consumer side terminal 60 so as to be comparable. This includes things like
Further, for example, this week's power generation amount of a portion of the remote power generation equipment 30 corresponding to the equipment capacity invested by consumer B and this week's power consumption of consumer B are displayed on the consumer side terminal 60 in a manner that can be compared. This includes things like
Further, for example, the amount of power generated this month in the portion of the remote power generation equipment 30 corresponding to the equipment capacity invested by customer B and the amount of electricity consumed this month by customer B are displayed on the customer side terminal 60 so as to be comparable. This includes things like
Then, the process returns to step 210.

In this embodiment, by having the configuration as described above, the following operations and effects are achieved.

In this embodiment, the initial investment amount of a business operator who newly creates remote power generation equipment 30 using renewable energy such as solar power generation is an amount corresponding to the installed capacity (power kW), and consumer B: Invest in installed capacity (power kW). Since it is not an investment in the amount of electricity (kWh), the business operator does not need to guarantee the amount of electricity (kWh).
Here, if the amount of electric power (kWh) were to be guaranteed, the risk would be large because the remote power generation equipment 30 is renewable energy (solar power generation, etc.) that has a large fluctuation range due to seasonal factors and the like.
In contrast, the present embodiment is an investment in electric power (kW) called equipment capacity, and is an investment in a part of the power generation capacity of the remote power generation facility 30 using renewable energy. Consumer B will take over a portion of the operator's initial investment through investment, lowering the hurdles for starting a power generation business, and allowing operator A to participate in the power generation business without shouldering large risks. You can start a business.

On the other hand, consumer B also uses part of the business-use solar power generation equipment, such as a mega-solar system, rather than residential solar power generation equipment, compared to the case where a home solar power generation system is installed on the roof of his own home. That way, construction costs and other costs will be much lower and it will be possible to use it for a longer period of time. In addition, it will open the door to the use of renewable energy for consumer B who lives in small houses and housing complexes (condominiums, apartments, housing complexes, etc.).

According to the present embodiment, information regarding the amount of power generation is reported in real time to consumer B who has invested in the installed capacity of the remote power generation facility 30 for a predetermined period, so that consumer B can monitor the invested installed capacity in real time. You can easily find out information about the amount of power generated by

By setting the installed capacity of the remote power generation equipment 30 using renewable energy for a predetermined period as a target for consumer B's investment and business operator's sales, consumer B's investment (purchase) and business operator's Various purchasing plans and sales plans can be made for selling installed capacity. For example, if the setting is such that the cost of electricity purchased from the power grid differs between daytime and nighttime hours, consumer B may invest (purchase ) becomes possible. On the other hand, business operator A consumes the electricity generated by the remote power generation equipment 30 himself during the daytime when purchasing electricity from the power grid is expensive, and only sells electricity to consumer B during the nighttime when the cost is low. becomes possible.

According to this embodiment, in the case where consumer B lives in the Kanto region and the remote power generation facility 30 is installed in the Kyushu region, which is a remote location from the Kanto region of consumer B, the sunlight at sunrise and sunset The time will be shifted forward or backward by about 40 minutes. Specifically, for example, when setting electricity rates on a real-time hourly basis, customer B in the Kanto region may have already set the sun and cannot make effective use of solar power generation; This means that solar power generation can be used effectively even before sunset. By appropriately adjusting the investment time contract, consumer B, who normally has a heavy load in the evening when solar power generation cannot be used effectively, can effectively use solar power generation and gain profits. becomes possible.

According to this embodiment, it is possible to regenerate low solar radiation areas where the amount of solar radiation is low and the generation efficiency of solar power generation is low, and areas where wind power generation has low operational efficiency due to weak wind and unstable wind direction. Even if consumer B lives in an area with low energy potential or in an area where there is no renewable energy power generation facility nearby, they can receive renewable energy by investing in the installed capacity of the remote power generation facility 30. can pave the way for the use of

According to this embodiment, by providing information such as the power generation amount of the remote power generation equipment 30 to consumer B in real time, consumer B can predict the future power generation amount based on the information. Become.
In addition to information regarding the amount of power generated by the remote power generation facility 30, the information providing means 50 also provides various meteorological information such as a weather forecast for the area where the remote power generation facility 30 is located, which is other information necessary to predict the future amount of power generation. Data is provided to consumer B. Thereby, future power generation amount can be predicted with high accuracy.

According to the present embodiment, the power generation equipment side measurement device 32 measures information regarding the amount of power generated by the remote power generation equipment 30, and the expense billing server 40 measures the information based on the measurement result measured by the power generation equipment side measurement device 32. , calculates information regarding the amount of power generated by a portion of the remote power generation equipment 30 that corresponds to the installed capacity invested by customer B, for the customer B who has invested in the installed capacity of the remote power generation equipment 30 for a predetermined period; . Then, the server communication device 43 of the information providing means 50 transmits the information regarding the calculated power generation amount to the consumer side terminal 60 of the consumer via the network line, so that the consumer B can control the remote power generation equipment 30. You can know the exact amount of power generated by the portion of the equipment that corresponds to the installed capacity you have invested.

According to this embodiment, the consumer can more accurately predict future power generation amount based on data such as solar radiation, temperature, humidity, atmospheric pressure, wind speed, wind direction, etc., and weather forecast data.

According to the present embodiment, the remote power generation equipment 30 is provided with the storage equipment 31 for storing power, so that the power generated by the remote power generation equipment 30 is prevented from being output suppressed (connection refused), or the output In the case of suppression (connection refusal), the power generated by the remote power generation equipment 30 can be stored, making it possible to efficiently supply power.

According to the present embodiment, the consumer side terminal 60 stores the power consumed by consumer B and the generated power generated by a portion corresponding to the equipment capacity invested in remote power generation equipment 30 by consumer B. By being displayed at the same time, you can adjust power consumption in real time by adjusting the operation of devices that consume power to reduce power consumption so that it does not exceed the generated power, and to match the power consumption to the generated power. becomes possible.

According to the present embodiment, when the unit price of electricity is set uniformly without fluctuation, the amount of electricity consumed by consumer B among the remote power generation equipment 30 is The billing amount is calculated based on the value obtained by subtracting the integrated value of the amount of power generated by the portion corresponding to the installed capacity invested by B. Thereby, it is possible to easily calculate the corresponding billing amount when the unit price of electricity does not change due to time factors and is uniform.

In addition, the method of calculating the billing amount is not limited to the method described above, and if the unit price of electricity is set uniformly without fluctuation, the amount of electricity consumed by consumer B during the billing period is Billing is based on the amount obtained by multiplying the unit price by the integrated value of the amount of power generated by the portion of the remote power generation equipment 30 that corresponds to the installed capacity invested by consumer B from the amount obtained by multiplying the unit price. The amount may be calculated. Even in this case, it is possible to easily calculate the corresponding billing amount when the unit price of electricity does not change due to time factors and is uniform.
