Description

Environment value management auxiliary device and method

Technical Field

The present invention relates to a technology for assisting environmental value management, and more particularly, to a technology for a company to more effectively implement environmental measures that apply renewable energy to electricity consumption of the company.

Background

Recently, there are increasing cases in which, due to the influence of climate change such as global warming, an enterprise is evaluated between a consumer, an investor, and the like to recognize the environment and perform an activity, and purchase and investment are determined by the evaluation. Accordingly, the cases of enterprises aiming at reduction of greenhouse gas emissions, introduction of renewable energy sources, and the like are increasing, and countermeasures such as CDP (project of disclosing environmental strategy and emission of greenhouse gas is required by upper enterprises of non-profit groups who cooperatively operate and set up offices in london to market values of major countries), RE100 (international enterprise union of enterprises aiming at making 100% of electric power used to be electric power generated by renewable energy sources), and the like are expanding internationally. In recent years, attempts have been made to reduce the environmental load of the entire supply chain of the company as well as the company as the supply chain discharge amount.

When a business introduces renewable energy into the use power of the business, there is a means for supplying power generated by solar power generation or hydroelectric power to a contracted power retailer or the like. In addition, there are the following means: the part of the renewable energy source where the CO2 emission is reduced by another operator is traded as an environmental value, and the renewable energy source is considered to be used by the use of electric power applied to the non-renewable energy source of the company, and the J-credit system and the like are equivalent to this in japan. In either case, the present company is managed to introduce an environmental measure such as the introduction of renewable energy sources by managing the power/environmental value of which means the present company has generated.

As a conventional technique related to such environmental value management, for example, patent document 1 discloses a system for properly evaluating environmental value of renewable energy sources. In the case where an enterprise performs environmental measures, a certificate circulated in a form shown in patent document 1 can be purchased. Patent document 2 describes a power source management device as a conventional technique for subdividing an object to be managed of environmental value into devices.

In the prior art, in order to accurately import and manage environmental values for loads caused by activities of the enterprise to the enterprise, problems exist in terms of accuracy and range. In the related art, it is only possible to manage an extremely limited object, specifically, a case where the object is fixed to a power supply device of the company and the company can easily obtain the power supply amount to the object.

However, the use of electric power that does not meet these conditions has various problems. For example, an electric vehicle (hereinafter referred to as EV) does not necessarily need to be charged with electric power in its own company power supply equipment, and can be charged by a charging pile (stand), a socket, or the like outside the company. In recent years, remote operations such as satellite offices and home operations have been increased, and notebook computers at this time are also being supplied with power from outside the company. The above-described case should be implemented in an enterprise having and operating an EV or a notebook computer to manage environmental value in terms of using electric power for enterprise activities, but cannot be managed in the prior art.

In addition, in the example of charging an EV, there are a plurality of related persons such as manufacturers, rental owners, users, operators of charging piles, and power retailers of the EV, and each of the related persons has a certain responsibility for environmental load during EV charging. These correlators share responsibility related to environmental load, and for example, by applying an environmental certificate (hereinafter, sometimes referred to as "certificate") corresponding to a part of the amount of electric power used, the system can be performed at a lower cost than when environmental measures are performed by one company.

Detailed Description

The embodiments will be described in detail with reference to the drawings. However, the present invention is not limited to the description of the embodiments described below. It will be readily appreciated by those skilled in the art that the specific structure may be altered without departing from the spirit or scope of the invention.

In the structure of the embodiments described below, the same reference numerals are used between the drawings for the same portions or portions having the same functions, and overlapping description may be omitted.

When there are a plurality of elements having the same or similar functions, the same reference numerals are given to different subscripts to explain the description. However, when it is not necessary to distinguish between a plurality of elements, a description of the subscript may be omitted.

The expressions "first", "second", "third", and the like in the present specification are added for identifying the constituent elements, and are not necessarily limited in number, order, or content. The numbers used for identifying the components are used for each context, and the numbers used in one context do not necessarily indicate the same structure in the other contexts. The components identified by a certain number may also have the functions of components identified by other numbers.

For easy understanding of the invention, the positions, sizes, shapes, ranges, and the like of the respective structures shown in the drawings and the like may not indicate actual positions, sizes, shapes, ranges, and the like. Therefore, the present invention is not necessarily limited to the position, size, shape, range, etc. disclosed in the drawings and the like.

Publications, patents and patent applications cited in this specification are incorporated directly into the specification as part of the specification.

In this specification, constituent elements expressed in the singular form include plural forms unless the context indicates otherwise.

An example of the embodiment described below is an environmental value management support device that supports environmental value introduction during power use by an enterprise. The device comprises: a device power supply data acquisition unit that collects information on a device and a power supply; a device power supply connection identification unit that identifies between which device and which power supply the user wants to manage; a power composition acquisition unit that integrates what environmental value is applied to various subjects associated with power supply; a power supply amount estimation unit that performs estimation when the power supply amount is not clear; and an environmental value distribution unit that compares the power composition information acquired by the power composition acquisition unit and the power supply amount estimation unit with an environmental value distribution target, and distributes an environmental value when the power composition information is insufficient.

According to the technology described in the embodiments, it is possible to estimate the power supply amount of a wide range of combinations of devices and power sources including the amount of power that cannot be measured, and to visualize and allocate the environmental value that the relevant other person has allocated and the environmental value that the company should allocate based on the visualizations, and it is possible to advance efficient environmental measures for the enterprise.

The concept of environmental value proposed in recent years is as follows. The electricity obtained from fossil fuel and atomic energy is the same as the electricity obtained from renewable energy sources based on solar energy and wind power, but the electricity based on renewable energy sources is called green electricity, and has an "environmental value" such that carbon dioxide is not discharged, in addition to the "value of electricity and heat itself". Thus, the portion of the "environmental value" can be taken out to be treated as a "certificate" having an economic value. In the present embodiment, "environmental value" and "certificate" are specifically limited values (data) that can be allocated to electric power. As a unit of environmental value, for example, the J-credit (credit) sets a unit for the amount of CO2 to be reduced. Alternatively, the energy may be converted into an electric power supply amount or a ratio of renewable energy sources in the electric power supply amount.

By purchasing such a certificate, the electric power used corresponding to the purchased "environmental value" can be regarded as electric power supplied by renewable energy sources. As a precondition for such a system, it is necessary to know how much power is available to consumers and operators from renewable energy sources.

Example 1

The embodiments are described below with reference to the drawings, but in the examples, embodiments that can be implemented by partial modification are described as modifications in each example.

Fig. 1 shows a schematic configuration of an information processing system 1 of embodiment 1. The information processing system 1 includes an environmental value management support device (hereinafter referred to as "support device 10"), one or more equipment-side servers 2, one or more power-supply-side servers 3, and one or more power purchase management servers 4. Which are all information communication devices (computers) connected via a communication network 5.

The auxiliary device 10 and each server may be configured by a single computer, or any part of the input device, the output device, the processing device, and the storage device may be configured by another computer connected via the communication network 5.

Fig. 2 shows main functions of the auxiliary device 10, the equipment-side server 2, the power-supply-side server 3, and the power purchase management server 4. As shown in fig. 2, the auxiliary device 10 includes functions of a device power supply data acquisition unit 111, a device power supply connection identification unit 112, a power composition acquisition unit 113, a power supply amount estimation unit 114, and an environmental value distribution unit 115.

As will be described later with reference to fig. 7, each function of the auxiliary device 10 may be configured by a general server having a processor, a memory, a communication device, an input/output device, a storage device, and an internal signal line. The device power supply data acquisition unit 111, the device power supply connection identification unit 112, the power composition acquisition unit 113, the power supply amount estimation unit 114, and the environmental value distribution unit 115, which are indicated by broken lines, are realized by a processor executing programs stored in a memory. The device power supply connection information 151, the environmental value distribution target 152, the environmental value distribution result 153, the power supply individual log T600, and the power supply integration log T1000 are stored as data in the storage means.

The device-side server 2 manages information on the device that has received the supply for the power supply that may be the object of the system management of the power supply amount/the environmental value. The device-side server 2 may be configured by a general server having a processor, a memory, a communication device, an input/output device, a storage device, and an internal signal line. The equipment-side server 2 collects and stores data of various equipment-side logs 121, equipment information lists 122, equipment position information histories 123, and power supply amount estimation specification information 124, and supplies the data to the auxiliary device 10. The information existing in the device-side server 2 may be provided by a correlator (manufacturer, seller, user, etc.) related to the device.

The power source side server 3 manages information on the power source to be supplied to the power supply that may be a target of system management. The power source side server 3 may be configured by a general server having a processor, a memory, a communication device, an input/output device, a storage device, and an internal signal line. The power source side server 3 collects and stores data of various power source side logs 131, a power source information list 132, power supply amount estimation specification information 134, differential measurement electrical system configuration information 135, and differential measurement log 136, and supplies the data to the auxiliary device 10. The information existing in the power source side server 3 may be provided by a correlator (manufacturer, provider, etc.) related to the power source.

Fig. 3 is a diagram showing a configuration example of the device-side log 121. As a device to be supplied with power, a user can arbitrarily set an EV, a smart phone (smart phone), a notebook PC, a mower, a factory device, and the like. In the present embodiment, the supply of electric power is performed in a one-to-one relationship between one power source and one device. The supply of electric power is not limited to charging, and the supplied electric power may be consumed immediately.

The device side log 121 stores information as shown in fig. 3. In the example of fig. 3, information including a start time 311 of charging, an end time 312 of charging, a device ID313 of a device to be charged, a power source ID314, a data manager 315, a power supply amount 316, a location 317, and a renewable energy ratio 318 of a charged energy source is included. This is an example, and there may be missing data and additional data. The information of the device-side log 121 is acquired by a device to which power is supplied, for example, by a known method, and is collected in the device-side server 2 via the communication network 5.

In addition to the start time 311, the end time 312, the device ID313, and the data manager 315, there may be defects in the power supply ID314, the power supply amount 316, the position 317, and the renewable energy ratio 318 (# 2, #3, #4 in fig. 3).

The power ID314, the power supply amount 316, and the renewable energy ratio 318 need to be obtained from the power source side or input separately. The power supply amount 316 may be measured by the device itself. In the case where the position is not a fixed position with respect to the position 317, the device needs to have a function of measuring the position (for example, GPS (Global Positioning System: global positioning system)). If no information is obtained, this is indicated by unknown (unknown) in fig. 3 (# 3 in fig. 3).

The data manager 315 represents a participant (actor) that manages data of each line of the log, and can be a data manager for, for example, an EV, a manufacturer of the EV, a rental provider, a user, or the like. For the same power supply, there may be different logs based on multiple data managers.

The renewable energy ratio 318 represents the proportion of the electric power generated by the renewable energy source, such as the data manager 315 purchasing the renewable energy source or applying an environmental certificate as a substitute for the renewable energy source.

Fig. 4 is a diagram showing a configuration example of the power supply-side log 131. The user can arbitrarily set the EV charger, the green outlet, the battery, the outlet, and the like as the target power source.

The power supply side log 131 stores information as shown in fig. 4. In the example of fig. 4, information including a start time 321 of charging, an end time 322 of charging, a device ID323 of a device to be charged, a power source ID324, a data manager 325, a power supply amount 326, a location 327, and a renewable energy ratio 328 of energy to be charged is included. This is an example, and there may be missing data and additional data. The information of the power source side log 131 is acquired by a power source by a known method, for example, and is collected to the power source side server 3 via the communication network 5.

The information that may be defective is basically the same as the device-side log 121 of the device-side server except that it is not the power ID324 but the device ID323 (# 2, #3, #4 of fig. 4). In addition, when the power supply amount 326 of the charged electricity and the renewable energy ratio 328 are measured on the power source side, they can be included in the data.

Fig. 5 is a diagram showing a configuration example of the device information list 122. In the example of fig. 5, the device information list 122 includes information of a device ID of a device to be charged, a data manager 412 of the device, a location 413 of the device, a renewable energy authentication 414 of the device, a renewable energy ratio 415 of the device, and a category 416 of the device. The information on the device information list 122 is collected and collated by the manager of the device side server 2, for example, information provided by the data manager, and is stored in the device side server 2.

Unlike the device-side log 121, the device information list 122 manages information that does not change with time. There may be a defect in data other than the device ID411 and the data manager 412. The position 413 may be described as "unknown" in the case where the value is fixed regardless of the time in the device information list 122, but is different depending on the time. The information shown in fig. 5 is minimal, and for example, information about the device such as the model number and manufacturer of the device may be additionally held.

The renewable energy authentication 414 indicates whether the data manager 412 has accepted the authentication by ensuring that the power used by the device is 100% renewable energy.

The renewable energy ratio 415 is described as 415 when it is a fixed ratio independent of time, as in the renewable energy ratio 318 in the equipment-side log 121.

Fig. 6 is a diagram showing a configuration example of the power supply information list 132. In the example of fig. 6, the device information list 421 includes information of a power source ID of a charged power source, a data manager 422 of the device, a location 423 of the device, a renewable energy authentication 424 of the device, a renewable energy ratio 425 of the device, and a type 426 of the device.

The power supply information list 132 is substantially the same as the device information list 1221, except that the power supply ID421 is used instead of the device ID411 of the device information list 122. The information of the power supply information list 132 is collected and collated by, for example, a manager of the power supply side server 3, and stored in the power supply side server 3.

Referring to fig. 1 and 2, power purchase management server 4 supplies an environmental value holding amount 141 that can be allocated by the system to auxiliary device 10. The power purchase management server 4 may be configured by a general server having a processor, a memory, a communication device, an input/output device, a storage device, and an internal signal line. The environmental value-keeping amount 141 manages the kind and amount of environmental value that a user using the system holds and that the system can apply.

In fig. 2, the storage device of the auxiliary device 10 stores device power supply connection information 151, an environmental value allocation target 152, an environmental value allocation result 153, a power supply individual log T600, and a power supply integration log T1000.

The device power connection information 151 manages information indicating that a connection and power supply are performed between the device and the power supply. The device power connection information 151 is described later using fig. 11.

For the power supply that is the object managed by the system, the environmental value-distribution target 152 manages the conditions (equipment, date and time, power source, etc.) that are the objects to which the environmental value should be distributed, and information indicating the ratio of the environmental value to the power supply amount that should be distributed. The environmental value allocation target 152 is, for example, information acquired by an operation input from a user. The environmental value allocation target 152 is described later using fig. 22.

The environmental value distribution result 153 manages information about the date and time, the equipment, the power source, and the power composition with respect to the power supply amount that is the subject of system management. The environmental value allocation result 153 will be described later using fig. 23.

The power supply individual log T600 is an intermediate product obtained in the middle of the processing of the device power supply data acquisition unit 111 and the device power supply connection identification unit 112. First, the data is generated as a result of the processing by the device power supply data acquisition unit 111, and then the records are edited appropriately as a result of the processing by the device power supply connection identification unit 112. The power supply individual log T600 is described later using fig. 9.

The power supply integration log T1000 is an intermediate product obtained as a result of the processing by the power composition acquisition unit 113 and the power supply amount estimation unit 114. The power composition acquisition unit 113 generates a power supply individual log T600, and the power supply amount estimation unit 114 edits the generated log appropriately. The power supply integration log T1000 is described later using fig. 13.

In the function of the auxiliary device 10 shown in fig. 2, the device power supply data acquisition unit 111 acquires information of the device side server 2 and the power supply side server 3 via the communication network 5, and generates a power supply individual log T600 based on the information.

If the power source ID or the device ID is not clear in the power supply individual log T600, the device power source connection identifying unit 112 estimates the device power source connection information 151 and the information of the device side server 2 and the power source side server 3, and updates the power supply individual log T600.

The power composition obtaining unit 113 replaces a part of the ambiguous items in the power supply individual log T600 with a default value, integrates a plurality of records of the same power supply, calculates a renewable energy ratio/renewable energy importer for each power supply, and generates a power supply integration log T1000.

When the power supply amount is not clear in the power supply integration log T1000, the power supply amount estimation unit 114 obtains and uses the device position information history 123, the power supply amount estimation specification information 124, the power supply amount estimation specification information 134, and the difference measurement electrical system configuration information 135 of the power supply side server 3 of the device side server 2, and estimates the power supply amount, thereby updating the power supply integration log T1000.

For each object to be managed specified by the environmental value allocation target 152, the environmental value allocation unit 115 acquires a corresponding record from the power supply integration log T1000, determines whether or not the renewable energy ratio satisfies the target, and if not, performs environmental value allocation with reference to the environmental value holding amount 141 acquired via the communication network 5, and outputs the environmental value allocation result 153.

Fig. 7 is a diagram showing an example of a hardware configuration of the assist device 10 shown in fig. 1. The auxiliary device 10 has a processor 21, a memory 22, a communication device 23, an input-output device 24, a storage device 25, and an internal signal line 26. The input/output device 24 is connected to a monitor 27, a keyboard 28, and a mouse 29.

The memory 22 is configured by a volatile storage medium such as DRAM, and stores a device power supply data acquisition program 711, a device power supply connection identification program 712, a power configuration acquisition program 713, a power supply amount estimation program 714, and an environmental value allocation program 715. The processor 21 as a processing unit executes programs stored in the memory 22 to realize the functions of the device power supply data acquisition unit 111, the device power supply connection identification unit 112, the power configuration acquisition unit 113, the power supply amount estimation unit 114, and the environmental value distribution unit 115 described in fig. 2. In the present embodiment, each function is installed by software, but may be installed by hardware.

The storage 25 is constituted by a nonvolatile storage medium such as a hard disk drive, and stores device power supply connection information 151, an environmental value allocation target 152, an environmental value allocation result 153, a power supply individual log T600, and a power supply integration log T1000.

Next, the processing performed by the assist device 10 will be described. The main processing performed by the auxiliary device 10 is roughly classified into processing for generating the power supply integration log T1000 based on the information of the equipment-side server 2 and the power supply-side server 3 (hereinafter referred to as "power supply log generation processing S500") and processing for generating the environmental value allocation result 153 based on the environmental value allocation target 152 and the power supply integration log T1000 (hereinafter referred to as "environmental value allocation processing S1700"). These processes are performed at fixed intervals, for example, every month, in accordance with the unit in which the system user manages the environmental value.

Fig. 8 is a flowchart showing the power supply log generation process S500. The assist device 10 generates the power supply integration log T1000 by executing the process S500.

First, the device power supply data acquisition unit 111 acquires the device log 121 and the power supply log 131 from the device server 2 and the power supply server 3 during the period to be managed in the present process (S511).

Subsequently, the device power supply data acquisition unit 111 generates a record of the power supply individual log T600 for all records of the acquired log (S512).

Fig. 9 shows an example of the power supply individual log T600. In S512, the records acquired from the device-side log 121 of the device-side server and the power-side log 131 of the power-side server are transferred for each item including the unknown log. For example, entries #1 to 4 of fig. 9 are transfer records of the device-side log 121 of the device-side server of fig. 3, and entries #5 to 8 are transfer records of the power-side log 131 of the power-side server of fig. 4.

In addition, regarding the renewable energy authentication 619, the device power supply data acquisition unit 111 searches the device information list 122 or the power supply information list 132 based on the recorded device ID613 or the power supply ID614, and acquires and records whether or not the renewable energy authentication is performed for the corresponding device or power supply.

Next, returning to fig. 8, the device power connection identifying unit 112 determines whether or not any of the device ID613 and the power ID614 is unknown in the record of the power supply individual log T600 (S513). The processing from S513 to S514 is performed on each record of the power supply individual log T600. In the power supply individual log T600 of fig. 9, in the case of #2, #6, either one of the device ID613 and the power ID614 is ambiguous.

Next, in S513, if either one of the device ID613 and the power ID614 is ambiguous, the device power connection identifying unit 112 estimates the ambiguous ID using the device power connection information 151 and the information of the device-side server 2 and the power-side server 3 (S514). Fig. 10 shows details of the processing of S514.

Next, the power composition acquisition unit 113 integrates a plurality of records representing the same power supply in the power supply individual log T600, and generates a power supply integration log T1000 (S515). Details of the processing of S515 are shown in fig. 12.

Next, the power supply amount estimating unit 114 determines whether or not the power supply amount 616 is not clear in the record of the power supply integration log T1000 (S516). S516 and S517 are performed on each record of the power supply integration log T1000.

Next, in S516, when the power supply amount 616 is not clear, the power supply amount estimating unit 114 estimates the power supply amount as not clear using the device position information history 123, the device-side power supply amount estimation specification information 124, and the power supply-side power supply amount estimation specification information 134 (S517). Fig. 14 shows details of the processing of S517.

Next, the power supply amount estimating unit 114 determines whether or not the power supply amount 616 is not clear in the record of the power supply integration log T1000 (S518). S518 and S519 are performed on each record of the power supply integration log T1000.

Next, in S518, when the electric power supply amount 616 is not clear, the electric power supply amount estimating unit 114 estimates an electric power supply amount that is not clear using the electric system configuration information for differential measurement 135 and the log for differential measurement 136 (S519). Fig. 17 shows details of the processing of S519.

The description of the power supply log generation process S500 ends above.

Fig. 10 is a flowchart illustrating a process S514 in which the device power connection identifying unit 112 estimates an ambiguous device ID613 or power ID614. The device power connection identifying unit 112 estimates the device ID613 or the power ID614, which is unknown, by using the device power connection information 151 and the information of the device side server 2 and the power side server 3. S514 is performed on each record of the power supply individual log T600.

First, the device power connection identifying unit 112 searches the device power connection information 151 based on the non-ambiguous information in the start time 611, the end time 612, the device ID613, or the power ID614, and determines whether or not there is corresponding information (S711). Regarding the start time 611 and the end time 612, an appropriate margin may also be allowed.

Fig. 11 shows an example of the device power connection information 151. The device power connection information 151 is registered when the device is fixedly set and always connected to a specific power supply (case #3 in fig. 11). In addition, information known in advance, such as a case where charging is periodically performed between a specific power source and a device, may be recorded. The device power connection information 151 can be collected via the communication network 5.

When charging the device by connecting it to a power supply, if a fee is charged by using a smart phone or the like, the device such as the smart phone may be authenticated, and the IDs of the power supply and the device may be read and recorded (cases #1 and #2 in fig. 11). The reading can use QR codes (registered trademark), RFID (Radio Frequency Identifier ).

Category 818 represents the category of the acquisition source of these connection information. The definition of the category can be arbitrarily set. Further, the charged power source and the charged device are premised on one-to-one.

The application start time 811 and the application end time 812 represent a period in which the connection relationship between the device and the power supply is maintained, and data of the application end time 812 is blank (-) in a case where the connection is not released after the connection, a case where the connection is always made, or the like. This may occur, for example, in the case of equipment fixed to a factory or the like (e.g., in the case of # 3). In the search at S711, the connection information between the application start time 811 and the application end time 812 is set as the start time 611 and the end time 612.

The device power connection information 151 is valid for associating the two logs when neither the device ID nor the power ID is recognized in the device-side log 121 and the power-side log 131. In the device-side log 121 and the power-supply-side log 131, two modes are considered as reasons for missing the device ID and the power ID. The first is a case where the device or the power supply does not have the function of identifying the ID. Second is the case where no ID or no identity is assigned on the original system. In the present embodiment, the second case is sometimes referred to as "no ID".

As described above, even when the device ID and the power ID are absent in the device-side log 121 and the power-side log 131, the two logs can be associated, and thus, there may be two modes in the case where information is recorded in the device power connection information 151.

The first mode is a case where both the device ID813 and the power ID814 are known (cases #1, #3 in fig. 11).

The second mode is a case where no ID is assigned to either the device or the power supply, but only the regenerated energy authentication is recognized (case #2 in fig. 11). In this case, the renewable energy authentication 815 is set to "True" (True), and it is necessary to record the authenticated side (device or power supply) in the renewable energy authentication target 816. In addition, one of the device ID813 and the power ID814 that has no ID is described as "no ID". As described above, "no ID" is different from "unknown" in data.

Returning to fig. 10, next, in S711, if there is corresponding information in the device power connection information 151 by the search based on the connection time, the device power connection identification unit 112 replaces the device ID or the power ID that is not clear in the power supply individual log T600 with the information of the device power connection information 151 (S712). Here, in S712, even if the ID of one of the device power connection information 151 is "no ID", substitution is performed.

For example, in S513 of fig. 8, it is found that the power ID of #2 of the power supply individual log T600 of fig. 9 is "unknown". In S711 of fig. 10, the connection time "2020/4/114" at #2 of fig. 9: 00-2020/4/115: 00 "retrieve device power connection information 151. Then, the case of #2 is extracted in the device power connection information 151 of fig. 11. Since the power ID814 of #2 in fig. 11 is "no ID", the "unknown" of the power ID614 of #2 in fig. 9 is replaced with "no ID".

Next, the device power connection identifying unit 112 determines whether or not any of the device ID813 and the power ID814 is "no ID" in the information acquired in S711 (S713). In the above example, it is determined that the power ID614 of #2 in fig. 9 is "no ID".

Subsequently, in S713, if a certain ID is "no ID", the device power connection identifying section 112 generates a new record in the power supply individual log T600 (S714). In the case of S714, as described above, the renewable energy authentication is given to the "ID-free" device or power supply.

Referring to fig. 9, the recording of the power supply individual log T600 generated in S713 is described. Let #9 of fig. 9 be the new record. The same contents as the S712 end time point of the record (in this example, # 2) to be processed in S514 to S711 are recalled regarding the start time 611, the end time 612, the device ID613, the power ID614, the power supply amount 616, and the position information 617. At the end time point of S712, the power ID614 of #2 is replaced with "no ID".

In the device power connection information 151, the data manager 615 records the value of the renewable energy authentication responsible person 817 together with the renewable energy authentication object 816 when the value is not clear, and records "ambiguity (device)" or "ambiguity (power)" together with the renewable energy authentication object 816 when the value is not clear. In the above example, the renewable energy authentication principal 817 "good" of #2 in fig. 11 is described together with the renewable energy authentication object 816 "power supply". The renewable energy authentication 619 is authenticated, and thus "True" is described, and the renewable energy ratio 618 is described as "100". By assigning an ID of "no ID", even a device or power supply that is not defined on the system can be considered as a device or power supply to which an environmental value is assigned.

When no device or power source is defined in the system, even when the responsible person (817) acquires the renewable energy authentication and takes the environmental value, the record is not registered in the device-side log 121 and the power source-side log 131. Therefore, in this state, since the information of the renewable energy authentication 815 of the renewable energy authentication responsible person 817 is missing, a new record is generated in S714.

Returning to fig. 10, next, if the corresponding information does not exist in the device power connection information 151 in S711, the device power connection identification unit 112 determines whether or not the position information 617 is not ambiguous (S715).

Next, if the position information 617 is not ambiguous in S715, the device power connection identification unit 112 searches the device-side log 121 and the device information list 122 or the power-side log 131 and the power information list 132 using the position information 617 as a key (S716). It is sufficient to search only on the side where the device ID613 or the power ID614 is ambiguous.

Next, the device power connection identifying unit 112 determines whether or not there is a device or a power source at a sufficiently close position in the position information 617 between the start time 611 and the end time 612 (S717). Whether or not the position information is sufficiently close can be determined by whether or not the position information is within a fixed distance, taking into consideration an error of the position information.

Next, if there is a sufficiently close device or power source in S717, the device power source connection identifying unit 112 acquires the ID of the nearest device or power source (including "no ID") and replaces the device ID613 or the power source ID614 (S718).

Next, if there is no sufficiently close device or power source in S716, the device power source connection identifying unit 112 sets the ambiguous device ID613 or power source ID614 to "unknown" (S719). That is, the information is originally described as "unknown", and if there is no corresponding information in S711 and there is no sufficiently close device or power source in S717, the information is directly described as "unknown" in S719. The above ends the description of the process S514.

Fig. 12 is a flowchart illustrating the process S515 of the electric power composition acquisition unit 113. The power composition acquisition unit 113 integrates a plurality of records representing the same power supply in the power supply individual log T600, and generates a power supply integration log T1000.

First, for the recording of the power supply individual log T600, the power composition acquisition unit 113 replaces it with "0" when the renewable energy ratio 618 is not clear, and replaces it with "false" when the renewable energy authentication 619 is not clear (S911).

Next, the power composition acquisition unit 113 acquires one record from the power supply individual log T600 (S912). At this time, when there is data in the power supply individual log T600 that the device ID613 is not "unknown" and the power source ID614 is not "unknown", the data is acquired. For example, a record of #3 of the power supply individual log T600 of fig. 9 is acquired.

Next, the power composition acquisition unit 113 acquires all the records having the same device ID613 or the same power ID614, which are the same as the record start time 611 and the end time 612 acquired in S912 or are similar to each other within a predetermined margin, from the power supply individual log T600 (S913). In S913, all the records related to the same power supply as the record acquired in S912 are acquired. For example, a record of #7 of the power supply individual log T600 of fig. 9 is acquired.

Next, the power composition acquisition unit 113 generates a record in the power supply integration log T1000 based on the records acquired in S912 and S913 (S914).

Fig. 13 shows an example of the power supply integration log T1000.

In S914 of fig. 12, one or more records acquired in S912 and S913 are aggregated into one record. The same-name items of the data of one record acquired in S912 are transferred to the power supply integration log T1000 with respect to the start time 1011, the end time 1012, the device ID1013, and the power ID1014, respectively. All the records acquired in S912 have the same start time/end time, and the device ID or the power ID are common, so that no contradiction occurs. In the above example, the record of #3 of the power supply individual log T600 of fig. 9 is recalled.

Note that, regarding the power supply amount 1016, the position 1017, and the renewable energy authentication 1019, when a value that is not unknown exists in any record, the value is transcribed, and when all the values are unknown, the value is unknown. In the above example, the recorded renewable energy ratio 618"30" of #7 of the power supply-individual log T600 of fig. 9 is recalled.

The renewable energy ratio 1018 is the sum of all the recorded renewable energy ratios, and is "100" when it exceeds 100[% ]. For example, when "rental company purchases and applies a renewable energy (certificate) corresponding to 10% of the charge amount of an EV" and "charging pile supplies 50% of the power supply amount of renewable energy", there are a log that "data manager is rental company and a log that" data manager is charging pile and that "renewable energy ratio is 50%" for power supply of an EV. Therefore, if they are integrated, it is possible to make such a power supply integration log that 60% has been burdened by the rental company and the charging stake. Then, when 100% is the target value, it is sufficient to further allocate environmental value or the like to fill the remaining 40%. Since the integration of the renewable energy ratio cannot be performed as in the present embodiment, the rental company may recognize only 10% of its own load, purchase the remaining 90% of the environmental value, and pay 50% of the unnecessary cost.

The renewable energy manager 1020 records a group of the data manager 615 and the renewable energy rate 618 in the record in which the renewable energy rate is not "0" in the power supply integration log T1000. For example, in the example #3 of fig. 13, the renewable energy ratio 1018 is 50% of the total of 20% of the load of P company and 30% of the load of Q company.

In addition, the renewable energy ratio 1018 is often the sum of the power source side and the device side in one-to-one power supply. The responsibility for the environmental value in this case is 2 people. In addition, as a responsible person, there are also 3 or more. For example, in the case where the equipment side is a rental EV, the borrower and the lender may be burdened with environmental values, and the responsible person on the equipment side may be 2 or more. In fig. 13, only the total value of the renewable energy ratio and the renewable energy manager 1020, which is the data manager, are shown, but the information may include the ratio of each of the users to whom the environmental value is actually applied.

Next, the power composition acquisition unit 113 deletes all records of the power supply single log T600 acquired in S912 and S913 and used for log generation in S914 from the power supply single log T600 (S915).

Next, the power composition acquisition unit 113 determines whether or not a record remains in the power supply individual log T600 (S916). If a record remains, the flow returns to S912, and the record is acquired again. If there is no remaining record, the process ends.

The description of the process S515 ends in the above manner.

Fig. 14 is a flowchart illustrating the process S517 of the power supply amount estimating unit 114.

First, the power supply amount estimation unit 114 determines whether or not the device ID1013 is not "unknown" in the record of the target power supply integration log T1000 (S1111).

Next, in S1111, if the device ID1013 is not "unknown", the power supply amount estimating unit 114 searches the device information list 122 based on the device ID1013 (S1112).

Next, the power supply amount estimating unit 114 determines whether or not the device is EV based on the type 416 of the device information list retrieved in S1112 (S1113).

Next, in the case of EV in S1113, the power supply amount estimation unit 114 estimates the upper limit and the lower limit of the power supply amount by using the device position information history 125 of the device side server 2. (S1114).

As a method of estimation in S1114, for example, the following estimation can be performed.

First, a travel history after the last EV was charged is acquired from the device location information history 125, and the upper limit and the lower limit of the charge margin at that point in time are estimated based on the travel distance, speed, and the like in the history. Here, the upper limit means a value larger than a range that is preferable as an actual value, and the lower limit means a value smaller than a range that is preferable as an actual value. By obtaining the maximum charge capacity from the power supply amount estimation specification information 124 of the device-side server 2, the upper limit and the lower limit of the power supply amount can be estimated as the maximum charge capacity-charge margin. The estimation may be performed by another method using the device location information history 125.

Next, the power supply amount estimating unit 114 searches the power supply amount estimating specification information 124 and 134 based on the device ID1013 and the power source ID1014, and obtains the corresponding specification information (S1115).

Fig. 15 shows an example of the specification information 124 for estimating the power supply amount on the device side. The device ID1211 includes a specification information name 1212, an upper limit/lower limit 1213, a numerical value 1214, and a calculation unit 1215. The manager who knows the specification of the device registers this information in advance.

Fig. 16 shows an example of the specification information 134 for estimating the power supply amount of the power source. Basically, the same as fig. 15 is adopted except that the device ID1211 is replaced with a power source ID 1221. The manager who knows the power specification registers this information in advance.

Returning to fig. 14, next, the power supply amount estimating unit 114 estimates the upper limit or the lower limit of the power supply amount based on the calculation unit 1215 of the acquired power supply amount estimation specification information 124 or the calculation unit 1225 of the specification information 134 (S1116). S1116 is executed for each of the specification information acquired in S1115.

As a method of estimation in S1116, for example, in the case of the charge capacity of fig. 15, there is no calculation means, and it is an estimated value of the power supply amount itself. Thus, 120[ kwh ] is obtained as the upper limit of the power supply amount.

For example, in the rated case of fig. 15, since the calculation means is x (time), a value obtained by multiplying 10kW by the time in the power supply integration log T1000, that is, the difference between the end time 1012 and the start time 1011, described in the specification information becomes the upper limit of the power supply amount.

Next, returning to fig. 14, the power supply amount estimating unit 114 selects one of the upper limit and the lower limit of the power supply amount estimated in S1114 and S1116, and records the estimated supply amount upper limit 1021 and the estimated supply amount lower limit 1022 in the power supply integration log T1000, respectively (S1117).

Here, the upper limits obtained in S1114 and S1116 are each larger than the actual power supply amount, and therefore, by selecting the smallest value among the upper limits, the value close to the entity can be used as the estimated value. In the lower limit, the maximum value may be selected in the same manner.

The description of the process 517 ends in the above.

Fig. 17 is a flowchart illustrating the process S519 of the electric power supply amount estimating unit 114.

First, the power supply amount estimation unit 114 determines whether or not the power supply ID1014 in the record of the target power supply integration log is unknown (S1311).

Next, if the power source ID1014 is not unknown in S1311, the power supply amount estimating unit 114 searches the electrical system structure information 135 for differential measurement based on the power source ID1014 (S1312).

Fig. 18 shows an example of the electrical system configuration information 135 for differential measurement. An application start time 1411, an application end time 1412, a lower power supply list 1413, and an upper measurement unit 1414 are described. The lower power list 1413 is a list composed of a plurality of power IDs, and in S1312, search is performed according to whether or not the power ID1014 matches the list.

The upper measurement unit 1414 indicates an ID of a measurement unit of an upper level constituted by a plurality of power supplies.

For example, when there are the power sources X1 and X2 in the room a, and the total of the power supply amounts of the power sources X1 and X2 can be measured by the power meter of the room a, the room a corresponds to the upper measurement unit, and the power sources X1 and X2 correspond to the lower power sources.

Returning to fig. 17, next, the power supply amount estimating unit 114 determines whether or not information conforming to the power supply ID1014 exists in the electrical system configuration information for differential measurement 135 (S1313).

Next, when the corresponding information is acquired in S1312, the power supply amount estimating unit 114 searches the log of the acquired upper measurement unit 1414 in the period overlapping with the start time 1011 and the end time 1012 from the difference measurement log 136, and acquires the corresponding record (S1314).

Fig. 19 shows an example of the log 136 for differential measurement. A start time 1511, an end time 1512, a measurement unit 1513, and a power supply amount 1514 are described.

Next, returning to fig. 13, the power supply amount estimating unit 114 calculates the power supply amount in the upper measurement unit 1414 from the record acquired in S1314 (S1315).

Here, the calculation of the power supply amount in S1315 will be described. Since the upper measurement unit 1414 also handles power supply of different power sources, the start time 1011 and the end time 1012 in the recording of the power supply integration log T1000 may be different from the start time 1511 and the end time 1512 of the recording acquired in S1314.

In the case where the start time 1511 and the end time 1512 are completely included in the recording of the power supply integration log T1000 for the recording acquired in S1313, the power supply amount is the power supply amount 1514 itself of the recording acquired in S1313.

Further, for the record acquired in S1314, when the start time 1511 and the end time 1512 exceed the periods of the start time 1011 and the end time 1012 in the record of the power supply integration log T1000, the power supply amount 1514 is calculated by multiplying the ratio of the overlapping period to the period between the start time 1511 and the end time 1512.

If there are a plurality of records acquired in S1314, the power supply amounts of the respective records calculated in the above-described steps are summed up. In the case where the record acquired in S1314 does not exist, since there is no power supply in this period, the power supply amount is calculated as 0.

The power supply amount of the upper measurement unit 1414 in S1315 is calculated by the above steps.

Next, the power supply amount estimation unit 114 searches the power supply integration log T1000 for the log of each power ID of the obtained lower power supply list 1413 in the period overlapping with the start time 1011 and the end time 1012, and obtains a corresponding record (S1316). However, the initial differential measurement object, i.e., the power ID1014 used for searching in S1312, is excluded.

Next, the power supply amount estimating unit 114 calculates the power supply amount for each power ID of the lower power source list 1413 based on the record acquired in S1316 (S1317). Here, when the electric power supply amount 1016 does not exist in the record acquired in S1315, calculation is performed using the estimated supply amount lower limit 1022 instead. The calculation method is the same as S1315.

Next, the power supply amount estimating unit 114 calculates an upper limit of the estimated supply amount based on the differential measurement, based on the power supply amount in the upper measurement unit 1414 calculated in S1315 and the power supply amounts (or the estimated lower limit thereof) of the other power sources in the lower power source list obtained in S1317 (S1318).

Specifically, the total value of the power supply amounts (or the estimated lower limit thereof) of the other power sources in the lower power source list obtained in S1317 is subtracted from the power supply amount in the upper measurement unit 1414 calculated in S1315.

A specific example will be described with reference to fig. 20. In the example of fig. 20, the power supply amount is estimated for the power supply between the device Y0 and the power source X0. First, in the differential measurement information acquired in S1313, the upper measurement unit is "room a", and the lower power supply list is described with "power supply X0, power supply X1". Next, in S1315, the power supply amount of the upper measurement unit "room a" is calculated, and found to be 300kWh here. In S1317, the lower limit of 100kWh is obtained as the power supply amount between the power source X1, which is the lower power source, and the connected device Y1. At this time, the power supply amount of the upper measurement unit "room a" is equal to the sum of the power supply amounts of the power supplies "X0" and "X1" of the lower power supply list by definition thereof, and therefore the power supply amount C1 in the power supply X0 can be expressed as c1=300-C2 using the power supply amount C2 in the power supply X1. Since 100kWh is obtained as the lower limit of the estimated amount of C2, c1.ltoreq.200 is obtained, and 200kWh is obtained as the upper limit of the electric power supply amount in the power source X0.

Returning to fig. 17, next, the power supply amount estimating unit 114 registers the power supply amount calculated in S1318 in the differential measurement estimated supply amount upper limit 1023 (S1319).

Next, the power supply amount estimation unit 114 registers smaller values of the estimated supply amount upper limit 1021 and the differential measurement estimated supply amount upper limit 1023 as the final estimated supply amount 1024 (S1320).

If differential measurement is not performed, the value of the estimated supply amount upper limit 1021 is recorded.

By S1320 comparing the estimated value of the upper limit of the power supply amount obtained in S1114 and S1116 separately with the upper limit of the estimated value obtained in S1317 based on the differential measurement, it is possible to select a smaller estimated value, that is, an estimated value close to the actual power supply amount.

The description of S519 ends in the above manner.

Fig. 21 is a flowchart illustrating the environmental value assignment process S1700. The assist device 10 generates the environmental value allocation result 153 by executing the process S1700.

First, the environmental value-distribution unit 115 obtains one target from the environmental value-distribution targets 152 (S1711). The steps after S1711 are performed on each of the environmental value-assigned targets 152.

Fig. 22 shows an example of the environmental value assignment target 152. Application start time 1811, application end time 1812, device ID1813, power ID1814, target renewable energy ratio 1818 are set.

In the case where either of the device ID1813 and the power ID1814 is blank (-), this indicates that the device ID or the power ID is applied regardless.

In the example of fig. 22, the device ID1813 and the power ID1814 are used to individually designate the device or the power of the object, but other condition setting columns may be added, and a plurality of devices or power sources may be designated collectively by the device, the owner of the power source, and the user. In this case, in the step described later, determination as to whether or not the record is a record that meets the target and the device information list 122 or the power supply information list 132 used for the determination are appropriately performed.

Returning to fig. 21, the environmental value assignment unit 115 acquires a record corresponding to the target acquired in S1711 from the power supply integration log T1000 (S1712).

Whether the target is met is determined based on the application start time 1811, the application end time 1812, the device ID1813, and the power ID 1814.

Next, the environmental value-distribution unit 115 creates a line of the environmental value-distribution result 153 from the record and the target of the acquired power supply integration log T1000 (S1713). The steps S1713 and later are performed on the records of the acquired power supply integration log T1000, respectively.

Fig. 23 shows an example of the environmental value assignment result 153. In S1713, the application start time 1911, the application end time 1912, the device ID1913, the power source ID1914, and the renewable energy authentication 1919 are respectively recalled from the items of the same name of the power supply integration log T1000. In addition, the target renewable energy ratio 1925 is recalled from the items of the same name of the environmental value allocation target 152.

Regarding the electric power supply amount 1915, the electric power supply amount 1015 is noted in the electric power supply integration log T1000, and the final estimated supply amount 1024 is noted in the case of "unknown".

The assigned renewable energy ratio 1918 and the assigned renewable energy responsible person 1920 respectively remember the renewable energy ratio 1018 and the renewable energy responsible person 1020.

In addition, in the case where the start time 1011 and the end time 1012 of the record acquired in S1712 are spent only on a part of the target application start time 1811 and the application end time 1812, in S1713, the application start time 1911 and the application end time 1912 are corrected based on the spent time, and the power supply amount 1915 is multiplied by the ratio of the spent time.

Returning to fig. 21, next, the environmental value-assigning unit 115 determines whether or not the record acquired in S1712 satisfies the target acquired in S1711 (S1714).

In the determination of whether or not the target is satisfied, a determination is made by comparing the target renewable energy ratio 1818 of the environmental value allocation target and the allocated renewable energy ratio 1918 of the generated environmental value allocation result 153.

Next, if the target is not satisfied in S1714, the environmental value-distribution unit 115 calculates a new renewable energy distribution ratio 1926 and a new renewable energy distribution amount 1927 in the environmental value-distribution result 153 (S1715).

Here, the new renewable energy distribution ratio 1926 is calculated from the difference between the target renewable energy ratio 1818 of the target compared in S1714 and the distributed renewable energy ratio 1918.

The new renewable energy distribution amount 1927 is calculated by multiplying the electric power supply amount 1915 by the new renewable energy distribution ratio 1926.

Next, the environmental value distribution unit 115 instructs the power procurement management server 4 to amortize the corresponding environmental value based on the new renewable energy distribution amount 1927 calculated in S1715 (S1716). In the power purchase management server 4, the new renewable energy allocation amount 1927 is subtracted from the environmental value held amount existing in the environmental value held amount 141.

The above ends the description of the process S1700 of the environmental value assigning unit 115.

According to the above embodiment, the power supply log generation process S500 is performed for the power supply between the device and the power source, the power supply amount is estimated for the device whose power supply amount is unknown based on the specification of the device/power source and the power supply of the other device/power source, the environmental value distribution state by the other relatives is obtained, and the environmental value distribution process S1700 is performed for the necessary and sufficient amount of environmental value distribution based on the environmental value and the environmental value distribution target already distributed by the other relatives, so that the promotion of environmental measures of the enterprise can be facilitated.

Example 2

In this embodiment, the processing in embodiment 1 is performed by a plurality of servers on the device side 2 and the power source side 3.

In the case of example 2, it is necessary to collect only information of environmental value distribution of other subjects and use the information for distribution of the own company as in example 1, and also to share the information of environmental value distribution of the own company with other companies.

Example 2 is substantially the same as example 1 except for 1 point. After the process in S1716 is completed, the distribution result of the company is output as S1717 in the form of the device-side log 121 or the power-supply-side log 131.

According to the above-described embodiments, it is possible to calculate information on power supply from a device to be supplied, a power supply for supplying power, and other devices, estimate missing information from the calculated information, and determine the configuration of the supplied power. In addition, the power supply amount is estimated so that the required amount of renewable energy can be appropriately calculated even without an electric power meter or the like. Thus, with respect to the supply of electric power between the device and the power source, it is possible to provide an environment value management support apparatus and method that can realize environment value management for a wide range of devices and power sources and can share environment measures among a plurality of correspondents.

For example, when the own EV receives power supply from the power supply device of another company, if the power supply of another company has already allocated an environmental value, it is possible to avoid repeated allocation of the environmental value to the own EV. In this way, power, equipment, other information can be integrated, the applied environmental value is visualized without omission or repetition, and the portion of the visualized environmental value deficiency target is rapidly allocated with certificates.
