Description

  The present invention relates to a power supply evaluation system, a power supply evaluation method, and a power supply evaluation program for effectively utilizing a power charge by utilizing liberalization of a power supply system.

  In consideration of effective use of resources and environmental load, each household is required to reduce power consumption. And the technique for promoting suppression of such electric power use is examined. For example, an environmental load evaluation system for evaluating resource consumption in an integrated manner and encouraging reduction of the environmental load has been studied (see Patent Document 1). In the technique described in this document, the control unit of the environmental load evaluation server acquires utility fee withdrawal information, obtains a past withdrawal amount, and calculates a reduction evaluation value. And a control part calculates an evaluation point using the evaluation point calculation formula which considered the regional attribute according to the reduction evaluation value.

  On the other hand, devices (such as smart meters) that can transmit power consumption via a network are also being studied. For example, a power supply system that avoids the risk of power outage of important facilities and reduces the cost of power interchange has been studied (see Patent Document 2). In the technique described in this document, the remote disconnection / insertion system is connected to the smart meter via a communication line.

  In addition, a technique for buying and selling emission rights in ordinary households using points has been studied (see Patent Document 3). In the technology described in this document, electric power is supplied to an end user site by an electric power company. The point server of the electric power company acquires the amount of power generation at the end user site, and converts the amount of power generation into points indicating the degree of contribution to the reduction of greenhouse gas emissions. These points are aggregated over all end-user sites and converted into greenhouse gas emission reductions.

  Conventionally, the supply of electricity has been carried out only by a power company (general electric utility) authorized by the country for each region. However, the system reform of liberalization of the power supply system has made it possible to purchase electricity from power producers and suppliers (PPS) that have newly entered the electric power business and power companies in other areas ( For example, Non-Patent Document 1).

Next, a processing procedure for supporting switching to PPS and evaluation of power usage using the system configured as described above will be described with reference to FIGS.
(Recovery plan support process)
Next, a collection plan support process for creating a cash flow will be described with reference to FIG.
First, the control part 21 of the electric power supply evaluation system 20 performs the specific process of evaluation object (step S1-1). Specifically, the balance management unit 210 of the control unit 21 outputs a target designation screen for designating a PPS switching target house on the display of the administrator terminal 10. In this target designation screen, aggregate information (name, address, area name) about the aggregate of PPS switching targets is input. Here, as a collective, an apartment house or a plurality of households in a specific area is applied. In this case, the balance management unit 210 assigns a group code to the aggregate information input on the target designation screen. Then, the balance management unit 210 generates an aggregate record 270 in which the group code and aggregate information are recorded, and registers the aggregate record 270 in the user information storage unit 27.

  Next, the control unit 21 of the power supply evaluation system 20 executes household information acquisition processing (step S1-2). Specifically, the balance management unit 210 of the control unit 21 outputs a household information input screen on the display of the manager terminal 10. On this household information input screen, information on the household composition of each household constituting the aggregate is sequentially input. In this case, the balance management unit 210 assigns a household code to each household input on the household information input screen. Then, the balance management unit 210 generates an occupancy status record 271 and registers it in the user information storage unit 27. This occupancy status record 271 includes a group code, a household code, and a household composition.

  When the input of all the household information is completed, the control unit 21 of the power supply evaluation system 20 executes a power prediction process based on the household information (Step S1-3). Specifically, the balance management unit 210 of the control unit 21 uses the household configuration recorded in the occupancy status record 271 and the usage statistics value recorded in the usage statistics table 240 of the statistical information storage unit 24. The power consumption is predicted. Then, the balance management unit 210 calculates the power consumption reduction effect (power consumption) and the power charge reduction effect (difference). This process will be described later with reference to FIG.

  Next, the control part 21 of the electric power supply evaluation system 20 performs the acquisition process of the existing installation information (step S1-4). Specifically, the balance management unit 210 of the control unit 21 outputs a facility information input screen on the display of the administrator terminal 10. On this equipment information input screen, information on existing power equipment that needs to be replaced when PPS is switched is input. In this embodiment, the device code and quantity of the device used in the existing facility are input. In this case, the balance management unit 210 generates an existing equipment record 272 in which a group code is recorded for the existing equipment input on the equipment information input screen, and registers it in the user information storage unit 27.

  Next, the control part 21 of the electric power supply evaluation system 20 performs the calculation process of the investment cost with respect to an alternative installation (step S1-5). Specifically, the balance management unit 210 of the control unit 21 specifies a corresponding device corresponding to the device code recorded in the existing facility record 272 in the alternative facility table 230 of the facility information storage unit 23. Next, the balance management unit 210 acquires the equipment unit price of the equipment code of the corresponding equipment from the equipment unit price table 231 of the equipment information storage unit 23. Then, the balance management unit 210 calculates the total amount of each corresponding device by multiplying the equipment unit price of the device code by the number of devices. Then, the balance management unit 210 calculates the facility cost of the alternative facility that is the sum of the total amount of each corresponding device.

  Next, the balance management unit 210 calculates an amount (initial) according to the equipment scale corresponding to the equipment code and quantity recorded in the existing equipment record 272 from the personnel cost table 232 recorded in the equipment information storage unit 23. Acquired as labor costs (initial). Then, the balance management unit 210 calculates the amount of capital investment (initial cost) by summing up the equipment cost and personnel cost of the alternative equipment.

  Next, the control part 21 of the electric power supply evaluation system 20 performs the setting process of the redemption time of a capital investment (step S1-6). Specifically, the balance management unit 210 of the control unit 21 outputs a redemption time input screen on the display of the administrator terminal 10. On this redemption time input screen, information on the redemption time for collecting the investment for switching the PPS is input. In this case, the balance management unit 210 generates a cash flow table 291 in which the redemption period (year) input on the redemption period input screen is developed, and registers the cash flow table 291 in the plan information storage unit 29.

  Next, the control unit 21 of the power supply evaluation system 20 executes surplus calculation processing (step S1-7). Specifically, the balance management unit 210 of the control unit 21 develops the power rate reduction effect (difference) calculated in step S1-3 in each year of the cash flow table 291. Furthermore, the balance management unit 210 obtains the incentive corresponding to the reduction effect of electric power consumption (electric power amount) from the negative watt table 250 recorded in the reduction support information storage unit 25. Then, the balance management unit 210 sets the difference in power rate and the incentive (negative watt incentive) as income in the cash flow table 291 for each year. Furthermore, the balance management unit 210 sets depreciation that develops investment costs (initial costs) in each year until the redemption period. Further, the balance management unit 210 acquires a maintenance / repair cost corresponding to the facility scale from the maintenance cost table 233 recorded in the facility information storage unit 23. Further, the balance management unit 210 acquires the amount (operation) from the personnel cost table 232 as the personnel cost (operation). Next, the balance management unit 210 develops maintenance and repair costs and labor costs (operations) each year. Then, the balance management unit 210 sets an amount obtained by subtracting maintenance and repair costs and labor costs (operation) from the income as a cost for returning the residents. Using the cost of returning the residents, a part of the difference due to PPS switching will be returned and incentives will be allocated to reduce electricity.

  Next, the control unit 21 of the power supply evaluation system 20 executes cash flow output processing at the time of PPS switching (step S1-8). Specifically, the balance management unit 210 of the control unit 21 outputs the cash flow table 291 recorded in the plan information storage unit 29 to the display of the administrator terminal 10.
