Regarding 2). Of these, the electrical equipment E (EA to EF) is a facility including a group of indoor wiring and various electrical devices provided in establishments and other facilities such as houses and stores. In FIG. Represent.

  In the example of FIG. 1, only the electric equipment EA is representatively shown, but there is a control device C for each electric equipment E. In addition, the electric equipment E includes a power generator, and in the example of the electric equipment EA, the power generator includes a solar battery panel P, a power conditioner (not shown) using an inverter or a converter, a reverse power wattmeter for power sale, and the like. Although the control device C is provided, the energy source of the power generation device may be of a type other than sunlight, such as wind power.

  There may be an electrical installation E that does not include a power generation device, and the control device C of such an electrical installation E does not require a power generation configuration such as a power conditioner.

  The power transmission network equipment X is for connecting the electrical equipment E corresponding to the user of the schedule information management service, and the schedule information management service is a calendar service that responds to the registration and inquiry of the schedule according to the date and time. Many representative information processing services send reminders. Since the function of the schedule information management service is also referred to as PIM (Personal Information Manager / Management), it is hereinafter also referred to as “PIM”.

  The PIM server S shown in FIG. 2 provides a PIM, and a user corresponding to the electrical equipment E (EA to EF) is not shown in the figure, but the PIM server S is connected to the PIM server S through a home or an Internet connection line of a mobile terminal. An action schedule is registered in advance.

  The power transmission network equipment X is provided at a plurality of section power transmission paths R for transmitting power between the electrical equipment E and the end of the section power transmission paths R, and the connection state between the section power transmission paths R or the section power transmission paths R A switching circuit SW that changes at least one of the connection states with the electrical equipment E. A part of the section transmission line is an inter-area transmission line RR.

  The information processing device 1 is a server device that receives information such as the amount of power generation from the electrical equipment E (EA to EF) and controls the power transmission network equipment X. As shown in FIG. Communication control unit 6, storage unit 7 such as a main memory or auxiliary storage device, and communication unit 8 (for example, a mobile communication network such as the Internet, mobile phone, PHS, public wireless LAN, etc.) , Various wireless and wired communication adapters, other communication circuits, communication devices, and the like).

  In the information processing apparatus 1, elements (11, 12, etc.) such as each unit shown in FIG. 2 are realized by the arithmetic control unit 6 executing the computer program stored in the storage unit 7. Of the elements to be realized, the mode of the information storage means is free and can be realized in any data format such as a file on the storage unit 7, or may be remote storage by network computing (cloud).

  The storage means may include not only a data storage area but also functions such as data input / output and management. In addition, the unit of the storage means shown in this application is for convenience of explanation, and the configuration can be divided or integrated as appropriate, and the processing data and processing results of each means are stored in addition to the explicit storage means. A storage means is used as appropriate.

  The arrows in the figure (for example, FIG. 1) supplementarily indicate the main direction of the flow of data, control, etc., and do not deny other flows or imply direction limitations. For example, before or after data acquisition in a certain direction, a data request or an acknowledgment (ACK) can occur in the reverse direction. In addition, each means other than the storage means is a processing means for realizing and executing the information processing functions and operations (for example, FIG. 1) described below, but these are functional units arranged for explanation. It doesn't matter if it matches the actual hardware elements or software modules.

[2. Action)
Of the system configured as described above, a processing procedure particularly related to the present embodiment is shown in a flowchart of FIG.
[2-1. Output of electricity supply and demand forecast)
The portion of FIG. 3 excluding the parentheses represents the basic operation of this embodiment. That is, the power generation amount acquisition means 11 predicts the power generation for each electrical facility E (EA to EF) for the target time (for example, the next few hours, the next day, etc., hereinafter referred to as “target time”). An amount is acquired (step S11).

  As one aspect of obtaining the predicted power generation amount, the power generation amount is received from the control device C of the electrical equipment E via the communication network N as needed, and the extension generation number is estimated based on the received power generation amount. It is conceivable to obtain an amount.

  As another mode for obtaining the predicted power generation amount, the average value and the like calculated by the power generation amount totaling means 80 as shown by the broken line from the power generation amount for each electrical equipment E received as described above are used for the season, day of the week, and time. A value corresponding to the target time may be read as the predicted power generation amount by accumulating in the predicted power generation amount storage unit 81 for each time such as a belt.

  On the other hand, the schedule acquisition unit 12 pre-corresponds to the electric equipment E or the region to which the electric equipment E belongs from the PIM provided via the communication network N (actually the PIM server S that provides it). Information on the registered action schedule of the user is acquired (step S12), and the acquired schedule is stored in the schedule storage means 21 (for example, the rightmost column in FIG. 4).

  As for the correspondence relationship between the electric equipment E and the user, for example, as illustrated in the left two columns of FIG. 4, for example, equipment information storage means includes identification information (for example, electric equipment ID) of the electric equipment E and a user account in the PIM. 82 are stored in association with 82 in advance.

  Then, the consumption calculation means 13 calculates the predicted power consumption based on the action schedule information acquired by the schedule acquisition means 12 (step S13). Here, the action schedule information represents the time zone and the action content (for example, FIG. 4), and the consumption calculation means 13 is assumed to store power consumption or power consumption per unit time that is assumed in advance according to the action content. The predicted power consumption is calculated based on the amount and the action schedule information.

  Furthermore, the excess / deficiency calculation unit 14 calculates the power of the electrical equipment E based on the predicted power generation amount acquired by the power generation amount acquisition unit 11 and the predicted power consumption amount calculated by the consumption amount calculation unit 13 for the target time. The excess / deficiency amount is calculated (step S14).

  FIG. 5 schematically illustrates power excess / deficiency for each electrical equipment E, such as “insufficient (−1)” and “surplus (+3)”, but the actual numerical value is power (XX kW) or Use electric energy (XX kWh) or other appropriate index. The prediction output means 15 outputs the power excess / deficiency amount calculated by the excess / deficiency calculation means 14 in this manner as power supply / demand prediction in an appropriate format such as text or image display (step S15).

[2-2. (Transmission based on power supply and demand forecast)
Further, in the information processing apparatus 1, the power transmission determining unit 31 transmits the power generated by the electrical equipment E between the electrical equipment E based on the power supply and demand prediction using the user action schedule information acquired from the PIM. The content is determined (step S16), and the power transmission control unit 32 controls the power transmission network facility X according to the power transmission content determined by the power transmission determination unit 31, and thereby the electric power generated by the electrical facility E is transmitted between the electrical facilities E. (Step S17).

  That is, according to said control, the switching circuit provided in the edge part of the section transmission path R plays the role of a connection node, and changes the connection state of the section transmission paths R or between the section transmission paths R and the electrical equipment E Any power transmission path can be set between any electrical equipment E as required. Then, the electric power generated by the electric equipment E is transmitted between the electric equipments E through this power transmission path.

  The control of the power transmission network equipment X by the power transmission control means 32 may be for each switching circuit SW of the power transmission network equipment X, or for a control device (not shown) of the power transmission network equipment X, and the control device sets each switching circuit SW. It may be controlled.

[2-3. (Transmission between regions)
In addition, power transmission may be performed between regions. The processing procedure in this case is the contents including the parentheses in FIG. That is, the excess / deficiency calculation means 14 calculates the excess / deficiency amount of power for the area to which the electrical equipment E belongs by means of aggregation by the power generation amount aggregation means 80 (step S14).

  The power transmission network facility X includes an inter-region transmission path RR for transmitting power between the regions to which the electric facility E belongs, and the power transmission determining unit 31 uses the calculated power excess / deficiency between regions. Is determined (step S16). Then, the power transmission control unit 32 controls the power transmission network facility X according to the determined power transmission contents between the regions, thereby transmitting power between the regions through the inter-region power transmission path RR (step S17).

  Furthermore, the action schedule in PIM is not limited to individual users, but is registered in association with all electric facilities E in the area or all users, so that power transmission between areas can be prevented in response to excess or shortage of power between areas. This makes it easier to handle.

  For example, as an example of excess or deficiency of electricity between regions, a certain area A shown in Fig. 1 is an elementary school athletic meet, so it is considered that there is a lot of going out and the amount of self-consumption is reduced, so there should be relatively more electricity. In this case, it is possible to conserve power by planning to reduce the output of the power plant that supplies power to the B district while arranging the sale of power from the A district to the adjacent B district.

  In the example of FIG. 1, some of the section transmission lines R (RR) in both the electric equipments E and between the regions so as to cancel out the power excess / deficiency schematically shown as “+3” and “−1”. ) And the switching circuit SW constitute a power transmission path indicated by a solid arrow. The section transmission line R (RR) indicated by the broken line is not used, but may be used when the state of the power excess / deficiency changes.

[3. effect〕
(1) As described above, in this embodiment, in cooperation with the schedule information management service provided via the communication network N, the power generation amount for each electrical equipment E and the information of the action schedule stored in advance for the target time. By predicting the power consumption according to the power consumption and outputting the power surplus and deficiency based on the power generation amount and the power consumption as a power supply and demand forecast, power trading can be conducted by comparing the power trading between the electrical facilities E and between the regions. Can promote. In addition, it can be used for power supply advance planning based on regional power supply and demand forecasts.

(2) In particular, in the present embodiment, the action schedule information indicating the time zone and the action content (for example, FIG. 4), and the information on the power consumption per unit time stored in advance according to the action content, By calculating the predicted power consumption based on this (step S13), a highly accurate calculation result can be obtained quickly with a small load.

(3) Moreover, in this embodiment, the information about the power transmission network equipment X connecting the electrical equipment E used by the user of the schedule information management service is obtained using the information on the action schedule of the user acquired from the schedule information management service. By controlling with the power transmission content determined by the processing device 1 (for example, step S17 in FIG. 3 and FIG. 1), it is possible to smoothly carry out the actual power transmission.

  In particular (FIG. 1), the switching circuit SW provided at the end of the section transmission path R serves as a connection node, and is necessary by changing the connection state between the section transmission paths R or between the section transmission paths R and the electrical equipment. Accordingly, any power transmission path can be set between any electrical equipment E. For this reason, in addition to cost reduction due to simplification of equipment, fault tolerance is also improved by bypassing the fault part. Furthermore, by providing the power transmission network facility X that is separate from the normal power system, it is possible to reduce the influence of a power system failure such as a power failure.

(4) Further, in the present embodiment, based on the power excess / deficiency calculated for each region to which the electrical equipment E belongs, the excess / deficiency is determined by the interregional transmission path of the transmission network facility (for example, the district A in FIG. 1). In addition to facilitating power trading, it is possible to respond to peak power and power system failures through regional cooperation.
