Description

  The present invention relates to an energy usage limit value setting device, an energy usage limit value setting method, and a program.

The Law Concerning the Rational Use of Energy (hereinafter referred to as the Energy Conservation Law) aims to further promote the rational use of energy in the business sector and the household sector where energy consumption has increased significantly. It was amended in May 2010 and was fully enforced from April 2010. As a result of the amendment of the Energy Conservation Law, the unit for energy management has changed from the unit of business such as factories and business establishments to the unit of business (enterprise unit). Penalties are imposed if the efforts are insufficient (see Non-Patent Document 1). For this reason, business operators are required to aggregate the amount of energy used by factories and sales offices belonging to the business operators so that the total usage does not exceed the limit value. Business operators are also required to save energy.
As a technology that can contribute to energy saving in units of business operators, Patent Document 1 collects energy consumption at each facility (factory, sales office, etc.) belonging to the same business operator, calculates the total amount, and gives a warning as appropriate. An originating system is disclosed.

In order to realize the purpose of the Energy Conservation Law and make energy conservation effective as a whole company, it is necessary to set limit values (numerical targets) appropriately and make efforts to realize them.
However, there is a possibility that it is not possible to achieve the restriction on the energy usage amount for the entire company only by setting a numerical target for each establishment (facility). On the other hand, even when a numerical target is set for the total amount of energy used by a business operator, it is necessary to set a numerical target for each office.
On the other hand, numerical targets set by careful analysis may actually deviate from the actual situation. In addition, the business environment is changing every moment, and even numerical targets once set must be appropriately modified and updated according to changes in the environment.

A determination unit that determines whether the energy usage amount for each facility acquired by the acquisition unit is larger than a limit value for each facility set by the setting unit;
When the determination unit determines that there are both a facility having a usage amount larger than the limit value and a facility having a usage amount smaller than the limit value, the setting unit has determined that the usage amount is larger than the limit value. Update the limit value set for the facility to an increased value, and update the limit value set for the facility whose usage is determined to be less than the limit value to a decreased value.
It is characterized by that.

  According to the present invention, it is possible to set a limit value for each facility so that the energy usage amount of the entire company achieves the target value. Moreover, the limit value of each facility can be updated according to the actual situation of energy demand.

(Embodiment 1)
First, the first embodiment of the present invention will be described.
A system 1 including an energy usage limit value setting device (hereinafter referred to as an energy limit value setting device) 100 according to Embodiment 1 includes a plurality of energy amount measurement devices managed by the same operator as shown in FIG. 200 and a plurality of equipment devices 300. In the present system 1, the energy amount measuring device 200 is installed for each facility 30 (facility 30 </ b> A, 30 </ b> B), and the energy limit value setting device 100 and the plurality of energy amount measuring devices 200 are connected via the communication line 10. In addition, the energy amount measuring device 200 and the plurality of facility devices 300 are connected via the power line 20. Hereinafter, the facility 30A and 30B are collectively referred to as the facility 30.

The energy amount measuring device 200 includes, for example, a watt-hour meter and a digital multimeter, and is disposed on a switchboard or the like of the facility 30, and measures the total energy amount used by the equipment device 300 installed in the facility 30. By integrating the amount of energy, the integrated amount of energy (the amount of energy used) is measured. Here, the integrated value of the energy amount refers to a value obtained by integrating (accumulating) the energy amount used by the facility 30 within an arbitrary period such as one day, one month, or one year.
In addition, the energy amount measuring apparatus 200 includes an RTC (Real Time Clock), a storage device, and the like, constantly measures the integrated value of the energy amount, and integrates the energy amount as shown in FIGS. 2 (a) and 2 (b). The value is associated with the measurement date and stored in the storage device. The energy amount measuring apparatus 200 can also store a graph indicating the relationship between time and the integrated value of the energy amount based on (history) information stored in the storage device.

  Returning to FIG. 1, the facility device 300 is an arbitrary device that uses (consumes) energy, and includes, for example, an electric device such as an air conditioner, a lighting device, and a ventilator. The facility device 300 is installed in the facility 30 and receives energy from the power line 20 and operates to use energy. For this reason, when the facility apparatus 300 operates, the integrated value of the energy amount increases.

  As illustrated in FIG. 3, the energy limit value setting device 100 includes a storage unit 101, an acquisition unit 102, a determination unit 103, a setting unit 104, a prediction unit 105, and an input unit 106.

  The storage unit 101 is configured by a predetermined storage device such as a RAM (Read Access Memory) or a flash memory, for example, and is necessary for executing each process in addition to an operation program (application) executed by a configuration unit such as the acquisition unit 102. Storing (storing) various data, data acquired or generated by execution of each process, and the like. The processing by the energy limit value setting device 100 is realized by each component executing an operation program stored in the storage unit 101.

  As shown in FIG. 4, the storage unit 101 identifies the facility 30 (here, the facility 30 </ b> A), and for each of a plurality of dates, the integrated value of energy amount and the limit value of energy amount. In addition, the predicted value of energy amount, a possible value, etc. are stored. And the value memorize | stored in the memory | storage part 101 turns into a past value (The integrated value of the past energy amount, etc.).

Here, the energy amount limit value is an upper limit value of the integrated amount of energy that is set in advance by the user or set by the setting unit 104, and is the energy amount limit determined by the company by the Energy Saving Act. The value is the amount assigned to each facility 30 belonging to the business. As the limit value of the energy amount, for example, an amount within an arbitrary period such as one day, one month, or one year is set.
The predicted value of the energy amount is an amount obtained by adding the energy amount predicted to be used in the future by the facility 30 to the integrated value of the energy amount used by the facility 30.
The interchangeable value is an amount obtained by subtracting a predicted value of energy amount (or an integrated value of energy amount) from an energy amount limit value.

  In the following, for ease of explanation, the integrated value of energy amount, the limit value of energy amount, the predicted value of energy amount, and the interchangeable value are values at one-hour intervals, which are one day (from 0:00 to 24). Time).

  Returning to FIG. 3, the acquisition unit 102 includes an interface for performing communication, and mediates communication performed between the energy limit value setting device 100 and the energy amount measurement device 200 in accordance with a predetermined protocol. By doing this, the integrated value of the energy amount of each facility 30 measured by the energy amount measuring device 200 is acquired via the communication line 10. The acquisition unit 102 includes an RTC or the like. For example, at a predetermined time, the acquisition unit 102 acquires an integrated value of the energy amount measured by the energy amount measurement device 200 and stores the integrated value in the storage unit 101.

  The determination unit 103 includes, for example, an arithmetic processing circuit such as a CPU (Central Processing Unit), a RAM serving as a work area, various drivers, and the like, and in each facility 30, an integrated value of energy amount or a predicted value of energy amount. It is determined whether or not the energy amount limit value has been exceeded. Moreover, the determination part 103 adds the interchangeable value in each facility 30, and determines whether the combined interchangeable value is positive (plus).

  The setting unit 104 includes, for example, an arithmetic processing circuit such as a CPU, a RAM serving as a work area, various drivers, and the like, and satisfies a predetermined numerical target indicating the upper limit of the total amount of energy used by the operator. The limit value which shows the upper limit of the usage-amount of energy for every 30 is set. Specifically, the setting unit 104 calculates an interchangeable value for each facility 30 and sets a limit value for the energy amount for each facility 30 based on the calculated interchangeable value. The facility 30 having a positive interchangeable value indicates that there is a surplus in the limit value of the energy amount by the interchangeable value. Therefore, a value obtained by subtracting only the interchangeable value from the energy amount limit value is set as a new energy amount limit value, and a value obtained by adding only the interchangeable value to the energy amount limit value of the other facility 30 is newly added. By setting the limit value for the energy amount, the limit value for the energy amount can be interchanged between the facilities 30. A method of setting the energy amount limit value will be described later.

  In addition, the setting unit 104 not only sets (updates) the limit value of the energy amount of each facility 30, but also notifies each facility 30 (the manager) of the facility 30 to reduce the energy used. It can also be done.

  The prediction unit 105 includes, for example, an arithmetic processing circuit such as a CPU, a RAM serving as a work area, various drivers, and the like, and predicts how the integrated value of the energy amount used by each facility 30 will change in the future. By doing so, the predicted value of the energy amount is calculated (predicted). A method for calculating the predicted value of the energy amount will be described later.

  The input unit 106 includes various keys, buttons, or a touch panel for receiving instructions from the user, and inputs various instructions and data. The input unit 105 receives, for example, the limit value of the energy amount for each facility 30 input by the user and stores it in the storage unit 101.

  Next, the operation of the energy limit value setting device 100 will be described with reference to FIG.

  Here, it is assumed that the storage unit 101 included in the energy limit value setting device 100 stores the limit value of the energy amount in each facility 30 in advance (step S101). The energy amount limit value stored in advance is, for example, a value obtained by equally dividing the energy amount limit value set for the business by the energy saving method by the number of facilities 30 or a value arbitrarily set by the user. The energy amount limit value is updated by setting the energy amount limit value by repeating the processing described later.

  When the predetermined time is reached and a processing start operation is received from the user, the acquisition unit 102 acquires the integrated value of the energy amount for each facility 30 measured by the energy amount measuring device 200 (step S102). The acquisition unit 102 integrates past energy amounts stored in the energy amount measuring apparatus 200 as illustrated in FIGS. 2A and 2B in addition to the accumulated amount of energy measured by the energy amount measuring apparatus 200. A value (history of integrated value of energy amount) is also acquired and stored in the storage unit 101.

  Next, the prediction unit 105 calculates (predicts) a predicted value of the energy amount based on the integrated value of the energy amount acquired in the above step (Step S103). The prediction unit 105 stores the difference value between the integrated value of the energy amount and the integrated value of the past energy amount (for example, the integrated value of the energy amount of today and the previous day) stored in the storage unit 101 at the same time, and A predicted value of the energy amount is calculated from the integrated value of the energy amount for the past day.

  Here, a method for calculating the predicted value of the energy amount will be described with reference to FIG. First, the prediction unit 104 has a difference value of 20 kWh (= 80 kWh−) between the integrated value of the current amount of energy at 12:00 today, which is the latest measured value, and the integrated value of the energy amount at 12:00 of the previous day, which is the same time as the previous day. 60 kWh). Then, the prediction unit 105 adds and adds the calculated difference value 20 kWh and the integrated value of the energy amount at 24:00 on the previous day 100 kWh corresponding to the integrated value of the energy amount used on the previous day. The calculated value 120 kWh (= 100 kWh + 20 kWh) is calculated as the predicted energy amount 120 kWh. This is because the history (graph) of the integrated value of the energy amount between today and the previous day is predicted (estimated) to be substantially equal, the predicting unit 105 has acquired the integrated value of the energy amount at each facility 30. The difference value of the integrated value of the energy amount between the time and the same time of the previous day is calculated, and the predicted value of the energy amount is calculated by adding the difference value to the integrated value of the energy amount used in the previous day.

  Next, the determination unit 103 determines whether or not the predicted energy amount exceeds the energy amount limit value in each facility 30 stored in the storage unit 101 (step S104).

  If the predicted energy amount does not exceed the energy amount limit value in all the facilities 30 (step S104; less than all), it is determined that there is no need to set (update) the energy amount limit value in step S102. Return.

  In all the facilities 30, when the predicted value of the energy amount exceeds the limit value of the energy amount (step S104; all exceeded), the energy amount used in the facility 30 belonging to the same company is large, Since there is a possibility that the limit value set for the person may be exceeded (becomes larger), the setting unit 104 gives a predetermined notification to all the facilities 30 (its manager) to reduce the amount of energy (step) S105), the process returns to step S102. By notifying all the facilities 30 to reduce the amount of energy, the amount of energy can be reduced as a whole company to which the facility 30 belongs. And by reducing the amount of energy for the entire company, the integrated amount of energy for the entire company can be suppressed so as not to exceed the limit value for the amount of energy imposed on the entire company by the Energy Saving Act. .

  In a case where there are both a facility where the predicted energy amount exceeds the energy amount limit value and a facility where the energy amount does not exceed the limit value (step S104; both), that is, the determination unit 103 determines that the predicted energy amount value is greater than the limit value. When the setting unit 104 determines that there are both a facility having a larger value and a facility having a predicted energy amount smaller than the limit value, the setting unit 104 determines the interchangeable value (= energy amount limit value−energy amount predicted value) in each facility 30. ) Is calculated (step S106). Here, as shown in FIG. 6, in the facility 30A, the limit value of the energy amount is 100 kWh, and the predicted value of the energy amount is 120 kWh, so the interchangeable value is −20 kWh (= 100 kWh−120 kWh), In the facility 30B, the limit value of the energy amount is 130 kWh and the predicted value of the energy amount is 100 kWh, so the interchangeable value is 30 kWh (= 130 kWh-100 kWh).

  Next, the prediction unit 105 adds up the interchangeable values in each facility 30, and the determination unit 103 determines whether or not the combined interchangeable value is negative (minus) (step S107). In FIG. 6, the interchangeable value at the facility A is −20 kWh and the interchangeable value at the facility B is 30 kWh, so the combined interchangeable value is 10 kWh (= −20 kWh + 30 kWh).

  If the total interchangeable value is negative (step S107; Yes), the amount of energy used in the facility 30 belonging to the same company is large and may exceed the limit set for the company by the Energy Saving Act. The setting unit 104 gives a predetermined notification to all the facilities 30 (the managers) whose interchangeable values are negative to reduce the amount of energy (step S108), and returns to step S102. Reducing the amount of energy for the entire company to which the facility 30 belongs by notifying the facility 30 having a negative interchangeable value, that is, the facility 30 that uses a large amount of energy, to reduce the amount of energy. Can do. And by reducing the amount of energy for the entire company, the integrated amount of energy for the entire company can be suppressed so as not to exceed the limit value for the amount of energy imposed on the entire company by the Energy Saving Act. .

  When the total interchangeable value does not become negative (step S107; No), the setting unit 104 newly reduces the energy amount limit value set in the facility 30 for which the interchangeable value is positive by a predetermined value. Set a limit value (update to a value that reduces the limit value), and set a new limit value that increases the limit value of the amount of energy set in the facility 30 for which the interchangeable value is negative (by a predetermined value) The limit value is updated to an increased value (step S109), and the process returns to step S102. Here, a method of setting the limit value will be described with reference to FIG. Since the interchangeable value of the facility 30A is −20 kWh and the interchangeable value of the facility 30B is 30 kWh, the facility 30A is a facility having a negative interchangeable value, and the facility 30B is a facility having a positive interchangeable value. is there. The setting unit 104 adds the energy limit value 20 kWh of the facility 30B to the energy amount limit value 100 kWh set for the facility 30A where the interchangeable value is negative, and sets a new energy amount limit amount 120 kWh (= 100 kWh + 20 kWh). To do. Further, the setting unit 104 sets a new energy amount limit value 100 kWh (= 120 kWh-20 kWh) by subtracting 20 kWh, which is interchanged with the facility 30A, from the energy amount limit value 120 kWh of the facility 30B. The setting unit 104 updates (resets) the energy amount limit value set in each facility 30 so that the interchangeable value in all the facilities 30 is 0 or more. Thereby, since the integrated value of the energy amount used in each facility 30 belonging to the operator can be suppressed to a limit value or less, the integrated value of the energy amount for the entire operator is imposed on the entire operator by the Energy Saving Law. It is possible to suppress the energy amount from exceeding the limit value.

  With the above processing, a limit value can be set for each facility according to the amount of energy used in the facility belonging to the same business. Moreover, the integrated value of energy amount can be suppressed below a limit value in each facility belonging to a business operator. Further, by notifying a facility with a large amount of used energy so as to reduce the amount of energy, the amount of energy can be reduced for the entire business operator to which the facility belongs. Thereby, the integrated value of the energy amount of the entire company can be suppressed so as not to exceed the limit value of the energy amount imposed on the entire company by the Energy Saving Law.

(Embodiment 2)
Next, a second embodiment of the present invention will be described. In the second embodiment, the energy amount limit value is set based on the power generation amount generated by the power generation device in addition to the interchangeable value in each facility 30. As shown in FIG. 7, the system 2 including the energy limit value setting device 100 according to the second embodiment includes a plurality of energy amount measurement devices 200, a plurality of facility devices 300, and a power generation device 400 that are managed by the same company. Composed. In the present system 2, the power generation device 400 is installed, and the power generation device 400 and the energy limit value setting device 100 are connected via the communication line 10.

  The power generation apparatus 400 is an arbitrary apparatus that generates power using natural energy. For example, a solar power generation apparatus that converts solar energy into electric power, a wind power generation apparatus that converts wind energy into electric power, and geothermal energy into electric power. It consists of a geothermal power generation device that converts to The energy stipulated in the Energy Saving Law is fuel, heat and electricity, but natural energy from wind power and solar power generation is excluded. For this reason, the power generation amount generated by the power generation device 400 is not subject to regulation, and is not included in the integrated value of the energy amount in the entire business.

  Further, the power generation device 400 includes a watt-hour meter, an RTC, a storage device, etc., and constantly measures the integrated value of the power generation amount generated by the self-device, and as shown in FIG. And the date and time when the integrated value of power generation is measured are stored in the storage device. Here, the integrated value of the power generation amount refers to a value obtained by integrating (accumulating) the power generation amount generated by the power generation device 400 within an arbitrary period such as one day, one month, or one year.

  The acquisition unit 102 included in the energy limit value setting device 100 according to the present embodiment acquires the integrated value of the power generation amount generated by the power generation device 400 in addition to the integrated value of the energy amount measured by the energy amount measuring device 200. Store in the storage unit 101.

  The setting unit 104 sets an energy amount limit value for each facility 30 based on the interchangeable value in each facility 30 and the integrated value of the amount of power generated by the power generation device 400. A method of setting the energy amount limit value will be described later.

  Next, the operation of the energy limit value setting apparatus 100 according to the present embodiment will be described with reference to FIG. The description of the same processing as in the first embodiment is omitted.

  In step S107, the prediction unit 105 adds the interchangeable value and the integrated value of the power generation amount in each facility 30, and the determination unit 103 determines whether the added value is negative. The integrated value of the power generation amount does not correspond to the integrated value of the energy amount in each facility 30, and is a value that can relax the limit value of the energy amount imposed on the entire operator, and therefore is a value corresponding to the interchangeable value. is there. For this reason, the determination part 103 determines about the value which added the interchangeable value and the integrated value of electric power generation amount. In FIG. 9, the interchangeable value in the facility A is −20 kWh, the interchangeable value in the facility B is 30 kWh, and the interchangeable value (the integrated value of the power generation amount) in the power generation apparatus is 100 kWh. The possible value is 110 kWh (= −20 kWh + 30 kWh + 100 kWh).

  When the sum of the interchangeable value and the integrated value of the power generation amount is negative (step S107; Yes), the amount of energy used in the facility 30 belonging to the same company is large and is set by the company according to the Energy Saving Act. Therefore, the setting unit 104 performs a predetermined notification so as to reduce the amount of energy to all the facilities 30 (the managers) of which the interchangeable value is negative (step S108). Return to step S102. By notifying the facility 30 having a negative interchangeable value, that is, the facility 30 that uses a large amount of energy, to reduce the amount of energy, the same effect as in the first embodiment can be obtained.

  When the sum of the interchangeable value and the integrated value of the power generation amount does not become negative (step S107; No), the setting unit 104 sets the energy amount limit value set for the facility 30 whose interchangeable value is positive. A new limit value reduced by a predetermined value is set (step S109), and the process returns to step S102. Here, a method of setting the limit value will be described with reference to FIG. Since the interchangeable value of the facility 30A is −20 kWh and the interchangeable value of the facility 30B is 30 kWh, the facility 30A is a facility having a negative interchangeable value. The setting unit 104 adds the energy limit value 20 kWh of the power generation device 400 to the energy amount limit value 100 kWh set in the facility 30 </ b> A whose accommodation value is negative, and adds a new energy amount restriction amount 120 kWh (= 100 kWh + 20 kWh). Set. The setting unit 104 distributes the interchangeable values of the power generation device 400 and updates (resets) the energy amount limit values set in each facility 30 so that the interchangeable values in all the facilities 30 are 0 or more. To do. Thereby, since the integrated value of the energy amount used in each facility 30 belonging to the operator can be suppressed to a limit value or less, the integrated value of the energy amount for the entire operator is imposed on the entire operator by the Energy Saving Law. It is possible to suppress the energy amount from exceeding the limit value.

  With the above processing, a limit value can be set for each facility according to the amount of energy used in the facility belonging to the same business. In addition, since the integrated value of the power generation amount corresponds to the interchangeable value, the integrated value of the energy amount exceeds the limit value of the energy amount by adding the value obtained by distributing the integrated value of the power generation amount to the limit value of the energy amount. Can not be.

  In addition, this invention is not limited to said embodiment, A various deformation | transformation and application are possible.

  The number of the energy amount measuring device 200, the facility device 300, and the power generation device 400 included in the systems 1 and 2 is arbitrary.

  The systems 1 and 2 can also include an equipment control device for controlling the operation of the equipment 300 for each facility 30. The facility apparatus control device acquires the limit value of the energy amount for each facility 30 stored in the storage unit 101 included in the energy limit value setting device 100, and the energy amount (integrated value) used by the facility apparatus 300 is the limit value. The operation of the equipment device 300 is controlled so as not to exceed. In addition, when the limit value of the energy amount of the facility 30 is updated and the updated limit value becomes larger than the previous limit value, the facility device control device installed in the facility 30 uses the energy amount that the facility device 300 uses. The operation of the facility apparatus 300 is controlled so as to suppress the above. Thereby, in each facility 30, since the integrated value of energy amount can be suppressed below the limit value, the integrated value of energy amount of the entire company is set to the limit value of energy amount imposed on the entire company by the Energy Saving Law. The following can be suppressed.

  In addition, when the predicted value of energy amount (or the integrated value of energy amount) exceeds the limit value in each facility 30, the facility apparatus control device sets (updates) the limit value of the facility 30 that exceeds the limit value. The energy limit value setting device 100 can also be notified. And the energy limit value setting apparatus 100 which received the notification from the facility apparatus control apparatus sets a limit value such that the predicted value of the energy amount does not exceed the limit value. Thereby, even if there is a facility 30 that exceeds the limit value, the limit value can be quickly updated.

  The integrated value of energy amount, the limit value of energy amount, the predicted value of energy amount, and the interchangeable value have been described with one day as one unit (separator), but any time such as one hour, one week, one month, etc. It can also be separated by units.

  The determination unit 103 can determine not only whether the predicted value of the energy amount exceeds the limit value of the energy amount, but can also determine whether the integrated value of the energy amount exceeds the limit value of the energy amount. .

  The prediction unit 105 can calculate the predicted value of the energy amount by an arbitrary method. For example, the acquisition unit 102 acquires the temperature around the facility 30 in addition to the integrated value of the energy amount, and stores the temperature in the storage unit 101. The predicted value of the above-mentioned energy amount obtained from the difference between the integrated value of the energy amount between today and the previous day is A, the temperature at the time when the integrated value of the energy amount was acquired, and the stored temperature on the previous day When the temperature difference (today's temperature-the previous day's temperature) is a number B, the prediction unit 105 can also obtain a predicted value of the energy amount as (number A × 0.05) × number B + number A. .

  In addition, the hardware configuration and the flowchart described above are merely examples, and can be arbitrarily changed and modified.

  In the above embodiment, the program to be executed is a computer-readable recording medium such as a flexible disk, a CD-ROM (Compact Disc Read-Only Memory), a DVD (Digital Versatile Disc), and an MO (Magneto-Optical Disc). A system that executes the above-described program may be configured by storing and distributing the program in a medium and installing the program.

  Further, the program may be stored in a disk device or the like of a predetermined server device on a communication network such as the Internet, and may be downloaded, for example, superimposed on a carrier wave.
