By the way, in order to introduce and operate such a power supply system, initial investment and running cost (hereinafter, also referred to as introduction cost) are incurred. Even if the reduction of electricity charges is realized by collective power reception, it is unclear at the time of introduction of the system whether or not the introduction cost can be recovered by the profit finally obtained by the reduction of the electricity charges.

Regarding this, it is possible to perform simulations according to various conditions in advance, but the actual results may not always be as simulated, so the owner of the complex facility should use the collective power supply system when introducing the collective power supply system. , You will bear the risk that the invested funds may not be recovered. For this reason, there is a problem that the spread of the power supply system as described above does not progress easily.

The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the risk of introducing a power supply system that supplies power to a complex facility including a plurality of power supply destinations.

In order to achieve the above object, the present invention adopts the following configuration. That is, it is an information processing device used together with a power supply system that supplies power to a complex facility including a plurality of power supply destinations.

<Application example>
Hereinafter, application examples of the present invention will be described with reference to the drawings. FIG. 1 shows a block diagram of a power supply system 90 to which the present invention is applicable. In FIG. 1, the solid line connecting each block indicates a power line, and the broken line connecting each block indicates a communication line (including wireless communication). The power supply system 90 according to this application example is premised on being applied to an apartment house 91. In this case, the apartment house 91 is an example of a complex facility including a plurality of power supply destinations.

In FIG. 1, the power supply system 90 is electrically connected to the power system 98. The electric power system 98 may be a so-called retail electric power company or a general electric power company. Further, a facility meter 94 is provided at the connection between the power supply system 90 and the power system 98, and it is possible to measure the power supplied from the power system 98 to the power supply system 90.

Further, as a plurality of power supply destinations of the power supply system 90, the exclusive units 96a, 96b, 96c ... Are assumed. The exclusive portions 96a, 96b, 96c ... Are, for example, each room (hereinafter, also referred to as a resident) in the apartment house 91. More specifically, the load in the exclusive portions 96a, 96b, 96c ... Is an electric product or the like (not shown) in each room of the apartment house 91. Further, in the apartment house 91, there is a common portion 97 in addition to the exclusive portion 96a, 96b, 96c ... The common area 97 is a common area in the apartment house 91, and the load of the common area 97 may be, for example, lighting of a corridor or an entrance. The exclusive portions 96a, 96b, 96c ... And the common portion 97 are provided with individual meters 95a, 95b, 95c ..., 95d, respectively, and the exclusive portions 96a, 96b, 96c ... And the common portion 97. It is possible to measure the power consumed in.

Further, the power supply system 90 has a management device 92 configured to be able to communicate with the system in the apartment house 91 outside the apartment house 91. More specifically, the management device 92 may be a server device provided on the cloud by a management company that is an operating entity of the power supply system 90. However, the management device 92 may be connected to the power supply system 90 by wire communication as long as it can exchange information with the system in the apartment house 91, and is not necessarily provided on the cloud. It doesn't have to be a new one.

Further, the power supply system 90 includes a compensation calculation device 93 configured to be communicable with the management device 92. FIG. 2 is a block diagram showing a schematic configuration of the compensation calculation device 93. The compensation calculation device 93 can be configured by, for example, a general-purpose computer, and includes functional modules of the balance forecast information acquisition unit 931, the security information acquisition unit 932, the actual balance calculation unit 933, and the compensation calculation unit 934. I have. In addition, although not shown, various input means such as a mouse and a keyboard, an output means such as a display, a storage means such as a RAM and an HDD, a communication means, and the like may be provided. The compensation calculation device 93 corresponds to the information processing device in the present invention.

The income and expenditure forecast information acquisition unit 931 is a functional module that acquires and retains the result of the income and expenditure forecast (hereinafter, also referred to as simulation) performed prior to introducing the power supply system 90 into the apartment house 91. In the simulation, for example, the estimated expenditure (cost) related to the introduction and operation of the system and the estimated income (income) obtained by the introduction of the system are calculated based on various conditions, and the system is based on these. It predicts how long it will take to turn a profit after the introduction of. FIG. 3 shows an image diagram of the simulation. In the figure, the horizontal axis shows the time axis, for example, the number of years elapsed since the introduction of the power supply system 90, and the vertical axis shows the cumulative value of the total amount of costs and profits incurred by introducing the power supply system 90. There is. Further, P in the figure represents a break-even point where the cumulative revenue exceeds the cumulative cost.

The guarantee information acquisition unit 932 is a functional module for acquiring and holding information of predetermined guarantee contents, which is predetermined based on the above simulation result. For the prescribed coverage, for example, the owner of the housing complex (hereinafter, also referred to as the owner) pays the insurance premium to the manager of the power supply system (for example, the person entrusted with the introduction and operation of the power supply system by the owner). In exchange for this, even when the break-even point P in the simulation arrives, if the cumulative profit is less than the cumulative cost, a part or all of the negative portion may be compensated.

The actual balance calculation unit 933 is a functional module that acquires the cumulative cost and the cumulative profit from the introduction of the power supply system 90 from the management device 92 and calculates the cumulative actual balance of the balance since the introduction of the power supply system. ..

The compensation calculation unit 934 will use the compensation calculation unit 934 at the time when the predetermined period has elapsed from the introduction of the power supply system 90, based on the simulation result, the predetermined guarantee content, and the cumulative actual amount of the balance. It is a functional module that determines whether or not a compensation is generated to compensate at least a part of the difference between the simulation result and the actual amount of income and expenditure, and the amount of the compensation. The time when the predetermined period has elapsed may be, for example, the time at the break-even point P described above.

Conventionally, the owner of an apartment house has introduced a power supply system for the collective power receiving business, and by a collective power receiving contract, the electricity consumed by the entire apartment house is procured at a low price, and a certain margin is added from each resident. It is done to earn profits by collecting electricity charges. This is a business model in which the introduction cost of the power supply system is recovered and further profits are obtained.

However, there are considerable risks associated with introducing a power supply system for the collective power receiving business. In other words, after the introduction of the system, it is assumed that the occupancy rate of the apartment house will be lower than expected, or the payment of electricity charges from the occupants will be delayed. The problem is that it is difficult to make a clear decision as to whether or not to turn a profit (when to turn a profit).

On the other hand, in this application example, when the compensation calculation device 93 is used and the actual amount of income and expenditure with respect to the simulation result is negative after a lapse of a predetermined period from the introduction of the system, at least the negative amount is obtained. It will be possible to partially compensate the owner. This makes it possible to reduce the risk when introducing a power supply system.

In the above-mentioned application example, the electric power supply system 90 is configured to procure the electric power used in the apartment house 91 only from the electric power system 98, but the electric power supply provided with other electric power procuring means such as a distributed power source. It is possible to apply the present invention to the system as well.

The series of processes can be regarded as an operation method of the power supply system executed by the management device 2 to reduce the risk of unrecovered investment of the equipment owner 23.

7 and 8 are flowcharts for explaining the flow of processing performed in the management device 2. In the management device 2, first, the balance forecast information acquisition unit 204 acquires information on the balance simulation result performed prior to the introduction of the power supply system 1 (S101). Specifically, for example, it may be acquired from another database (not shown) via a communication means, or the user may be requested to input information via an input means. Here, the information of the simulation result may include the information of the forecast time when the break-even point arrives.

Next, the security information acquisition unit 205 acquires information on the security content agreed between the equipment owner 23 and the management company 21 when introducing the power supply system 1 (S102). Here, regarding the contents of the guarantee, specifically, the amount of the insurance premium paid by the equipment owner 23 to the management company 21 (or reduced from the return fee to the owner), the amount of compensation (or the negative amount). The ratio, etc.) and the conditions for the compensation to be paid (for example, the average occupancy rate of the facility exceeds a predetermined value) may be included. In the management device 2, information on the initial cost spent for introducing the system (capital investment) is subsequently acquired (S103). Specifically, for example, it may be acquired from another database (not shown) via a communication means, or the user may be requested to input information via an input means.

When the process of step S103 is completed, the process of loop L1 described below is repeatedly executed every month. In the loop L1, first, the electricity charge calculation unit 201 calculates the electricity charge of each resident 22 (S104). More specifically, it is calculated by multiplying the power consumption of each resident 22 by the electricity rate unit price (yen / kWh). Then, a billing process is performed for each resident 22 (S105).

Next, income management is performed in the management device 2 (S106). More specifically, it is confirmed whether or not the payment of the electricity charges for the corresponding month from each resident 22 is completed, and in the case of receivables, a reminder process is performed. Further, information on the power purchase charge is acquired by the power purchase charge calculation unit 203 of the management device 2 (S107). More specifically, the invoice amount from the electric power company 20 stored in the power purchase charge calculation unit 203 may be referred to, or the power purchase charge is calculated from the amount of electric power purchased from the electric power company 20. You may. Then, the amount of return to the equipment owner 23 is calculated from the income amount calculated in step S106 and the power purchase charge calculated in step S107 (S108).

Next, the actual balance calculation unit 206 calculates the cumulative actual balance from the time of introduction of the power supply system 1 (S109). Specifically, even if the total amount of income and expenditure from the time of system introduction is calculated from the initial cost information acquired in step S103 and the cumulative amount of returns to the equipment owner 23 calculated in step S108. good.

Next, the compensation calculation unit 207 determines whether or not a predetermined period has elapsed since the introduction of the power supply system 1 (S110). Here, the predetermined period can be, for example, a period until the time when the break-even point P is set in the simulation arrives. If it is determined in step S110 that the predetermined period has not elapsed, the process proceeds to step S115, payment processing of the return amount calculated in step S108 is performed, and processing in loop L1 ends.

On the other hand, if it is determined in step S110 that the predetermined period has elapsed, a process of determining whether or not the compensation has already been paid is subsequently performed (S111). Here, if it is determined that the compensation has already been paid, the process proceeds to step S115, the payment processing of the return amount calculated in step S108 is performed, and the processing in the loop L1 ends.

On the other hand, if it is determined in step S111 that the compensation has not yet been paid, a process of determining whether or not a predetermined compensation condition is satisfied is subsequently performed (S112). Here, the predetermined compensation condition is, for example, whether the cumulative expenditure exceeds the cumulative income as of the month (that is, the balance is negative), or the average occupancy rate of the facility is equal to or higher than the predetermined value. There may be, and so on. If it is determined in step S112 that the predetermined compensation condition is not satisfied, the process proceeds to step S115, the payment processing of the return amount calculated in step S108 is performed, and the processing in the loop L1 ends.

On the other hand, if it is determined in step S112 that the predetermined compensation condition is satisfied, the compensation amount is subsequently calculated (S113). The compensation amount is calculated using the balance simulation result acquired in step S101, the information on the guarantee content acquired in step S102, and the cumulative actual amount of balance calculated in step S109.

Then, the compensation amount calculated in step S113 is added to the return amount calculated in step S108 (S114), the return fee payment process is performed (S115), and the process in the loop ends.

According to the present embodiment as described above, it is possible to reduce the risk at the time of system introduction even in a power supply system provided with a distributed power source that requires a large initial investment for introduction. .. For this reason, the hurdles for the owner to introduce the power supply system are lowered, and the management company can improve the contract rate of the collective power receiving consignment contract.
