[Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides an energy management system for managing an amount of energy, The power management system includes a storage unit, an acquisition unit, and a calculation unit.

[0046] <Functional configuration> 2(a), the information processing device 10 includes, as functional components, an acquisition unit 101, a calculation unit 102, a specific processing unit 103, and a display processing unit 104. These are information processing performed by software (stored in the storage unit 12) specifically realized by hardware (such as the control unit 11).

[0047] The acquisition unit 101 acquires (accepts) various information from a user terminal, the power DB 3, etc. The acquisition unit 101 acquires user information and company information. In this embodiment, the acquisition unit 101 acquires power classifications and power amounts for each power classification at each location, and stores them in the storage unit 12 in association with the hierarchical structure. The acquisition unit 101 also acquires hierarchical structure information and conversion information, and stores them in the storage unit 12.

[0048] The calculation unit 102 calculates the amount of CO2 emissions. In this embodiment, the calculation unit 102 calculates the amount of CO2 emissions of a specific dependent range specified by a user in the hierarchical structure of a demand company (organization) based on the amount of power associated with the hierarchical structure and the conversion information. The calculation unit 102 calculates the amount of CO2 emissions of the specific dependent range based on the conversion information including a CO2 conversion coefficient for each power plan defined for each power supplier.

[0049] Furthermore, the calculation unit 102 calculates the CO2 emission amount of a specific power class in a specific dependent range based on the power class specified by the user.

The display processing unit 104 can also process and display the CO2 emissions at a selected hierarchical location in the hierarchical structure based on the calculation result by the calculation unit 102, and transmit the display processing result.

[0053] <Database> 1 stores user information on users such as management personnel of demand companies, company information on demand companies, hierarchical structure information showing the subordinate relationships between multiple locations, conversion information for converting the amount of power into CO2 emissions, power information on the amount of power used by each demand company, and various other information necessary for power management. Some or all of these may be stored in the storage unit 12, etc., or some of these may be stored in another database, etc.

[0054] The power energy management system 1 and the processing contents of each functional component will be described below with reference to FIGS.

[0055] <Outline of the power management system> The power energy management system 1 of this embodiment is a system for simply and accurately managing CO2 emissions based on the amount of power consumed in each location at a power demand company having an organizational structure with bases scattered around the country.

[0056] That is, in the energy management system 1 according to this embodiment, in an organizational structure in which various bases are scattered across various locations, a specific range (specific location or subordinate range) can be freely set according to the user's wishes, and further, as necessary, CO2 emissions can be managed for each type of power determined by the power plan and voltage supply conditions of each electric utility (power supply company).The flow of processing in the energy management system 1 according to this embodiment will be described in detail below.

[0057] <Registering various information> 3 shows a flowchart of a processing procedure in the power energy management system 1 according to one embodiment of the present invention. In S201, a user, such as a person in charge of a demand company that uses electricity, registers user information in advance. In addition, the user (or the person in charge of the power energy management system 1) also registers company information related to the demand company to which the user belongs in advance. The acquisition unit 101 of the information processing device 10 acquires various information used for power energy management and registers it in the memory unit 12.

[0058] In addition to the management personnel of the demand company, the users in this embodiment also include, for example, on-site personnel of the prime contractor or cooperating company at the construction site, workers of the cooperating company, etc. (people related to the construction work). Some of the demand company personnel (management personnel) belong to the head office, while others belong to a branch office or a business site.

[0059] As shown in Fig. 4(a), user information includes information such as the user's name, contact information, company ID (described later), job title such as manager or section manager, duties such as administrator or site supervisor, affiliation such as head office or branch office, registration date, etc., and is managed by the user ID. Also, as shown in Fig. 4(b), company information includes information such as the company name, company contact information, company address, type such as prime contractor or partner company, etc., and is managed by the company ID. In this embodiment, CO2 emissions can be viewed, etc., based on the user information, company information, etc. For example, the viewing range of CO2 emissions can be limited based on attributes such as the user's job title and duties.

[0060] In the energy management system 1 of this embodiment, in addition to user information and company information, information regarding a hierarchical structure showing the subordinate relationships between multiple locations in a company (hierarchical structure information), and conversion information for converting the amount of energy for each energy classification based on specified conditions into CO2 emissions are also pre-registered.

[0061] A schematic image diagram of a hierarchical structure used in an energy management system according to an embodiment of the present invention is shown in Fig. 5. As shown in the figure, hierarchical structure information is information indicating the subordinate relationships at each location (base), such as branch office A and branch office B linked to the head office, business site 1 and business site 2 linked to branch office A, and business site 3 and business site 4 linked to branch office B.

[0062] In this specification, multiple bases such as a head office, a branch office, and a business site may be referred to as a location in a broad sense. Business sites include factories, offices, stores, and construction sites managed by prime contractors. Locations in the hierarchical structure of a demand company also include non-business sites (and unlinked locations) that are not directly linked to a head office or a branch office. For example, specific construction sites that are not linked to a head office or a branch office are also included.

[0063] As shown in FIG. 4(c), the hierarchical structure information includes company IDs, location names (hierarchical relationships), and other information necessary to express the hierarchical structure of the demand company, and is managed by a hierarchical structure ID. For example, the hierarchical structure information can be configured using a construction system at a construction site. More specifically, the hierarchical structure information can be configured using the hierarchical structure of the demand company included in the construction system. In this embodiment, this hierarchical structure information can be used to calculate the CO2 emissions of multiple locations having a dependency relationship of a specific range selected by the user (specific dependency range).

[0064] As shown in Fig. 6(a), the conversion information includes information such as electric power suppliers (and retail electric power suppliers) that share electric power with consumer companies such as XX Electric Power (XX Electric Power Co., Ltd.) and XX Power Co., Ltd., multiple electric power plans (contract plans) defined for each electric power supplier, CO2 conversion coefficients for each electric power plan, and menu descriptions of public organizations notified by each electric power supplier to the Ministry of the Environment and other public organizations, and is managed by a conversion ID. In this embodiment, this conversion information and the above-mentioned hierarchical structure information are used to realize a simple and accurate calculation of CO2 emissions.

[0065] FIG. 7 shows a schematic image of conversion information managed by an energy management system according to one embodiment of the present invention. Each electricity retailer is obligated to notify which of the plans set by the public body corresponds to its own electricity plan (contract plan). As shown in the schematic image of FIG. 7, for example, it is possible to associate the electricity plans provided by each electricity retailer to each consumer company with the plans notified to the public body, and to determine a CO2 conversion coefficient according to the correspondence between them. Naturally, it is also possible to obtain electricity plans from general electricity suppliers regardless of the schematic image of FIG. 7.

[0066] <Acquisition of power data> 3, the acquisition unit 101 of the information processing device 10 acquires the amount of power used by the demand company from the power DB 3, and stores the amount of power used by the demand company in association with the hierarchical structure of the demand company in the storage unit 12. In the power DB 3, power classifications (power plans and power types) at each location of the demand company and the amount of power for each power classification are stored in the storage unit 12 as power amount information.

[0067] As shown in Fig. 6(b), the power amount information includes information such as a company ID, a hierarchical structure ID, a power plan for each power company, a power type such as low-voltage lighting (e.g., single-phase 100-200V), low-voltage power (e.g., three-phase 200V), high voltage, and special high voltage, power amount (kWh) and a period during which the power amount was actually measured (not shown), the number of contracts (and / or the number of power lines) in an electricity contract for supplying power to each location, and the usage status of the number of contracts, and is managed by an electricity amount ID. The electricity contract in this embodiment is a contract for each plan with each electricity retailer (a contract for each power meter or smart meter). Note that in this specification, the number of contracts and the usage status of electricity contracts may be collectively referred to as contract information.

[0068] In this embodiment, the acquisition unit 101 can acquire the power consumption (and power classification such as power plan and power type) of the target demand company from the power management organization DB 3(a) managed by a power management organization such as the Power Data Management Association, or directly acquire the power consumption from the demand company DB managed by the demand company. Further, as shown in FIG. 1, the acquisition unit 101 can also acquire the power consumption of the target demand company from the electric utility DB 3(c) managed by an electric utility such as an electric power company.

[0069] <Calculation of CO2 emissions> In S203, the calculation unit 102 of the information processing apparatus 10 receives a specific subordinate range from the user terminal 2. The specific subordinate range here means that, for example, when the user (user terminal 2) designates (selects) the subordinate range of branch A in FIG. 5, the three bases (three locations), namely branch A, workplace 1 subordinate to branch A, and workplace 2 also subordinate to branch A, become the specific subordinate range. The calculation unit 102 can calculate the CO2 emissions in the designated specific subordinate range.

[0070] Also, in FIG. 5, when the user designates the subordinate range of the head office, all locations including the head office, branch A subordinate to the head office, branch B, and workplaces 1 to 4 subordinate to branch A and branch B become the specific subordinate range. In this case, the CO2 emissions of all bases in the demand company are calculated.

[0071] In S204, the calculation unit 102 calculates the CO2 emissions of the specific subordinate range designated by the user terminal 2. Specifically, based on the power consumption associated with the hierarchical structure and the conversion information, the CO2 emissions of the specific subordinate range designated by the user in the hierarchical structure are calculated.

[0072] For example, when the user designates the subordinate range of branch A in the schematic image diagram of FIG. 5, the power consumption (kWh) of hierarchical structure IDs 20011 (head office), 20012 (branch A), 20014 (workplace 1), and 20015 (workplace 2) in the hierarchical structure information of FIG. 4(c) is extracted from the power consumption information in FIG. 6(b), and the CO2 emissions are calculated based on the total power consumption obtained by adding these up.

[0073] According to this example, as can be seen from the power consumption information in Figure 4(c), the head office is under the jurisdiction of XX Electric Power, branch office A is under the jurisdiction of △△ Electric Power, and business site 1 and business site 2 are under the jurisdiction of XX Power Co., Ltd. In other words, each location is under the jurisdiction of a different electric power company, and each electric power company has different contract plans. In this case, since the CO2 emissions actually differ for each contract plan, calculating the CO2 emissions using the location-based CO2 conversion coefficient will not actually provide accurate results.

[0074] Therefore, in this embodiment, the CO2 emissions are calculated using more detailed conversion information (CO2 conversion coefficients) based on each contract of each electric power company according to market standards. In this embodiment, for a specific dependent range selected by the user from locations scattered throughout the country, the CO2 emissions can be calculated simply and accurately by using the detailed CO2 conversion coefficients based on each contract of each electric power company.

[0075] In addition, in this embodiment, in addition to calculating detailed CO2 emissions in a specific dependent range, hierarchical structure information, conversion information, and power information can be appropriately combined and used to calculate CO2 emissions in a range that meets the user's needs.

[0076] For example, the calculation unit 102 (or the acquisition unit 101) can receive a designation of a specific power plan from a user, and selectively calculate the CO2 emissions of a specific power plan in a specific dependent range based on the power plan designated by the user. In other words, the user can freely set the dependent range in the hierarchical structure of demand companies and the power plan to be used within that dependent range, and selectively calculate the CO2 emissions desired by the user based on the set conditions.

[0077] Furthermore, in this embodiment, the calculation unit 102 (or the acquisition unit 101) can selectively calculate the CO2 emission amount of a specific power type in a specific dependent range based on the power type (low-voltage lighting, low-voltage power, high-voltage, special high-voltage, etc.) specified by the user. In other words, the user can freely set the dependent range in the hierarchical structure of the demand companies and the power type, such as three-phase 200V, used within the dependent range, and selectively calculate the CO2 emission amount desired by the user based on the set conditions.

[0078] <Specific processing of electricity contracts> In S205, the identification processing unit 103 performs identification processing of the number of electricity contracts and their usage status. Specifically, the acquisition unit 101 acquires contract information related to electricity contracts for supplying power to each location, associates it with a hierarchical structure (electric energy information), and stores it in the storage unit 12. Then, the identification processing unit 103 performs identification processing of the number of electricity contracts in the specific dependent range and the usage status of the electricity contracts based on the contract information.

[0079] For example, at construction sites involving large-scale construction work, a single location (the construction site) is divided into multiple areas and managed (according to the construction period or by type of electricity), and a power meter is installed for each of the multiple areas, and an electricity contract is made.

[0080] In this case, even if a power meter is contracted and in operation in a certain area during a certain period of time, it is possible that the power supply operation has been stopped in a specific area because construction has already been completed at the present time. Also, one contract may be made in one area, but multiple contracts may be made in another area (or another period). In other words, in this embodiment, in addition to being able to grasp the amount of power (CO2 emissions) for each business or construction site, the user can also grasp more detailed information such as the number of electricity contracts and usage status.

[0081] <Display processing> In S206, the display processing unit 104 performs display processing of various information of the specific dependent range. Fig. 8 shows an example of a display processing result in the user terminal 2 according to an embodiment of the present invention. The display processing unit 104 performs display processing of the CO2 emission amount of the specific dependent range according to an input instruction from the user based on the calculation result by the calculation unit 102, and transmits the display processing result to the user terminal 2.

[0082] As shown in Fig. 8, a search area W20 showing a screen for searching for CO2 emission status and a result area W30 showing a screen for the search results are displayed on the display screen W10 of the user terminal 2. The search area W20 displays the organizational classification such as head office, branch office, or business establishment, the organization name, the display method for the search results such as monthly display or daily display, the power plan for selecting the power company or a plan available for contract with the power company, the power type for selecting low voltage or high voltage, and the aggregation period for selecting a specific period. The display processing unit 104 processes and displays information regarding the CO2 emission amount desired by the user based on the calculation results calculated using the hierarchical structure information, conversion information, power amount information, etc. in response to various selection inputs from the user terminal 2.

[0083] In the organization classification of the search area W20, the user can select locations such as the head office or branch office according to their wishes. In the organization name, a portion of the locations selected in the organization classification (if the organization classification is branch office, then branch office A) can be selected. For example, by selecting the head office, the CO2 emissions related to the head office are displayed, and by selecting a branch office, the CO2 emissions related to the branch office are displayed. In addition, by selecting the organization name (by scrolling or entering the name to select), a portion of multiple business locations can be selected and displayed. For example, the CO2 emissions of non-business locations that are not directly subordinate to the head office or unlinked locations, such as base F, can also be displayed.

[0084] Furthermore, as shown in Figure 9, when branch office A in the organizational classification is selected from the user terminal 2 and a subordinate relationship is selected, the display processing unit 104 displays the total CO2 emissions of all locations subordinate to branch office A (specific subordinate range) and the CO2 emissions of each of those locations in the result area W30.

[0085] In this embodiment, as shown in FIG. 8 (and FIG. 9), a power plan can be selected in the search area W20. The power plan is, for example, the power plan of each electric power supplier shown in the conversion information of FIG. 6(a). The display processing unit 104 can display the details of the power plans in the CO2 emissions of the specific dependent range based on the calculation result by the calculation unit 102, and transmit the display processing result to the user terminal 2. The display processing unit 104 can also selectively display the power plan selected by the user in the CO2 emissions of the specific dependent range.

[0086] In this embodiment, the power type can be selected in the search area W20. The power types include low voltage, high voltage, special high voltage, etc. For example, when selecting the power type, it is possible to select a detailed classification such as single-phase 100V to 200V (lighting) or three-phase 200V (power) for low voltage (not shown).

[0087] The display processing unit 104 can display the breakdown of the power types in the CO2 emissions in the specific dependent range based on the calculation result by the calculation unit 102, and transmit the display processing result. The display processing unit 104 can also selectively display the power type selected by the user in the CO2 emissions in the specific dependent range. The user can easily and accurately check the CO2 emissions and their breakdown for each power type, such as single-phase 200V (lighting) and three-phase 200V (power), high voltage, and special high voltage, in a certain specific dependent range.

[0088] In this manner, in this embodiment, the hierarchical structure of the organization and the power classifications such as power plans and power types can be freely set, so that the user can view and manage CO2 emissions with high accuracy in various ways.

[0089] As described above, the power management system 1 of the present invention can easily and accurately manage CO2 emissions in the organizational structure of consumer companies scattered across various locations by executing predetermined processing using a hierarchical structure showing the subordinate relationships between multiple locations, as well as characteristic conversion information and power classifications.

[0090] In addition, in this embodiment, the energy management of a consumer company having an organizational structure with bases and construction sites scattered across various locations has been described, but the same effects as the present invention can be obtained when the energy management system 1 is used in fields other than construction sites.
