This application claims priority from Japanese Patent Application No. 2022-033518 filed on March 4, 2022, and the content thereof is incorporated into the present application by reference.
In order to prevent the emission of greenhouse gases such as carbon dioxide that cause global warming, so-called decarbonization, which aims to break away from fossil fuels, has attracted attention. In this respect, a data center (DC) is equipped with a large number of information processing devices and communication devices, and their operation and operation require a large amount of electric power. Therefore, attempts have been made to achieve decarbonization by using renewable energy to operate and operate these facilities.

Here, in Patent Document 1, regarding the procurement of electric power for consumers, an electric power procurement support system supports the procurement of electric power for a plurality of consumers from a plurality of procurement sources. One or more consumer combinations in which a plurality of consumers are classified based on the received evaluation index, and one or more procurement sources for each consumer combination. It is described that the amount of power procurement and the determination of

By the way, the following circumstances exist in the data center. In other words, a data center has a housing (individual part) where users bring in equipment, etc., and a common part (backbone network equipment, etc.) where other equipment is installed for the operation of all users. is responsible for reducing emissions of greenhouse gases (here, carbon dioxide: CO2) derived from power consumption for the former, and businesses are responsible for the latter. In addition, since CO2 emissions can be reduced by using renewable energy, it is necessary to manage power usage and renewable energy.

However, it is difficult for each user to independently procure actual electric power and supply it to the equipment they have brought in, because it involves changes in the electric power equipment of the business operator. In addition, individual procurement such as environmental value certificates cannot take advantage of economies of scale and costs are high. Therefore, the cost can be reduced due to economies of scale by collectively procuring renewable energy for the business operator and for the user, and implementing renewable energy utilization for each user. However, the power consumption of common parts for which the operator is responsible changes depending on the usage status of the user. Furthermore, since the environmental requirements set by each user and business operator (such as the target percentage of renewable energy) are different, the amount of renewable energy to be procured by the business operator and the user together is calculated. It is difficult to calculate what should be done.
Under these circumstances, there is a demand for a mechanism for efficient management of renewable energy in cooperation with business operators and users.

The present invention has been made in view of such a background, and its object is to provide a renewable energy management device capable of efficiently managing renewable energy in facilities having common parts and individual use parts, and to provide a renewable energy management method.

One of the present inventions for solving the above problems is, in the power consumption of a facility that has a processor and a memory and is managed by a business operator and used by a user, the power consumption part associated with the business operator, The power consumption portion associated with the user is calculated, and the calculated power consumption portion and the power consumption portion of the facility managed and used by the user are associated with the business operator. a required renewable energy amount prediction unit that calculates the amount of renewable energy required to be procured by the business operator based on the parameter and the parameter associated with the user; and the calculated required renewable energy and a renewable energy procurement plan creation unit that outputs information about the renewable energy management device.

<Renewable energy procurement plan first creation process>
FIG. 11 is a diagram illustrating an example of processing for creating the first renewable energy procurement plan. For example, when the user makes a predetermined input to the management terminal 10 for the DC operator, this process is performed at a predetermined timing or time interval (for example, at the beginning of the fiscal year, when a contract regarding the user's environmental requirements is concluded or changed). ), it is started at

First, the DC operator management terminal 10 transmits a request to create a renewable energy procurement plan (s1). Upon receiving this creation request, the integrated DC management server 40 transmits a user environment requirement request requesting acquisition of user environment requirements to the DC user management server 50 (s3).

Upon receiving the user environment requirement request, the DC user management server 50 transmits information on the existing user's environment requirements (information on the DC user environment requirement table 600) to the integrated DC management server 40 (s5). . When the DC user management server 50 receives the information on the environmental requirements of the user, it sets the received information in the renewable energy management table 100 .

Also, the integrated DC management server 40 transmits to the DCIM 61 a request to obtain performance information regarding the operation of the data center 60 (s7). When the DCIM 61 receives this acquisition request, the DCIM 61 sends the integrated DC management server 40 performance information related to the operation of the data center (for example, history of configuration changes of each device in the data center, use of each device, each device or data center (the temperature of the common part and the individual part, and the power consumption of the device) are transmitted (s9).

When the integrated DC management server 40 receives the performance information regarding the operation of the data center, it calculates the renewable energy conversion factor for the business operator and each user (s11).

Specifically, the integrated DC management server 40 performs the following processing for each entity of the business operator and each user. That is, the integrated DC management server 40 refers to the renewable energy management table 100 and acquires the requirement item 102 and the requirement numerical value 103 of the record related to the subject.

Then, the integrated DC management server 40 calculates the conversion factor for the subject based on the acquired requirement numerical value 103 . For example, the integrated DC management server 40 uses the renewable energy rate, which is a requirement numerical value, as a conversion factor. Also, for example, the integrated DC management server 40 converts the CO2 emission reduction amount, which is a requirement numerical value, into a renewable energy rate using a predetermined conversion formula (for example, multiplying the total power consumption by an emission factor), and converts this into a renewable energy rate. Use the conversion factor. The integrated DC management server 40 sets the calculated conversion factor to the conversion factor 105 of the renewable energy management table 100 .

In addition, the integrated DC management server 40 refers to the renewable energy procurement method type table 200, and identifies the type ID of the record in which the acquired requirement item 102 is set in the compatible requirement 203, so that the regeneration of the subject is performed. Identify types of renewable energy procurement methods. The integrated DC management server 40 sets the identified procurement method type to the procurement method type 104 of the renewable energy management table 100 .

The integrated DC management server 40 executes an impact calculation process s13 for calculating the impact of each individual part on the common part (the impact on the required amount of renewable energy).

The integrated DC management server 40 calculates the total amount of required renewable energy for each type of procurement method specified in s11 (the total amount for business operators and all users; hereinafter referred to as the total required renewable energy amount by type). is executed.

The integrated DC management server 40 detects whether or not the total amount of required renewable energy calculated in the required generated energy amount prediction process s15 is currently insufficient for each type of procurement method specified in s11. Renewable energy An excess/deficiency detection process s17 is executed.

The integrated DC management server 40 determines whether procurement of renewable energy is necessary for each type of procurement method specified in s11 based on the result of the renewable energy excess/deficiency detection process s17 (s19). If it is necessary to procure renewable energy (s19: YES), the integrated DC management server 40 executes the renewable energy procurement plan s21 for creating (updating) the renewable energy procurement plan, and then the process of s23 is performed. executed. On the other hand, if procurement of renewable energy is not necessary (s19: NO), the integrated DC management server 40 executes the process of s23.

In s23, the integrated DC management server 40 transmits the current renewable energy procurement plan to the DC operator management terminal 10. FIG.
Next, the details of each of the above processes will be described.

<Influence calculation processing>
FIG. 12 is a flowchart for explaining the details of the impact calculation process s13. First, the impact calculation program 46 selects one user (s201).

If the user selected in s201 is an existing user, the impact calculation program 46 calculates the impact of the increase/decrease plan on the common portion (s203).

Specifically, the impact calculation program 46 calculates the impact from the increase/decrease in the power consumption 305 of the record related to the business operator in the required renewable energy amount prediction table 300 and the actual value of the power consumption acquired in s9. .

In addition, the impact calculation program 46 calculates the impact on the common part based on the current state of the device of the user selected in s201 (configuration or use of the device, etc.) (s205).

For example, the impact calculation program 46 determines the type of each device installed in the individual part of the user selected in s201 (e.g., server device, communication device) and the purpose of each device (e.g., arithmetic processing, communication processing). ) is obtained from the performance information received in s9. The influence degree calculation program 46 calculates a predetermined weight value (for example, the weight value of the server device is greater than the weight value of the network device) set for the type of each acquired device, and the usage or operation of each type of device acquired. A predetermined weight value set for the situation (for example, the weight value of a device for calculation is greater than the weight value of a device for communication; the higher the temperature of the device, the higher the weight value). Calculated for each The influence degree calculation program 46 sums up the calculated multiplication values to calculate the degree of influence of the selected user's individual portion on the common portion.

Note that the method of calculating the degree of impact on the common portion described here is just an example, and the degree of impact calculation program 46 may calculate, for example, the temperature of each device or the data center 60 (for example, the higher the temperature of the individual portion or the common portion, the higher the the degree of influence increases), the degree of influence may be calculated based on the air volume of the air conditioner and the power state of each device.

The impact calculation program 46 sets the total value of the impact calculated in s203 and s205 to the impact 106 of the renewable energy management table 100. Note that the method of calculating the degree of impact described here is just an example, and the degree of impact calculation program 46 may calculate the degree of impact by any method according to the user's increase/decrease plan and the device configuration of the individual part. .

The impact calculation program 46 checks whether there are any users who have not executed the processes of s203 and s205 (s207). If there is a user who has not executed the processes of s203 and s205, the impact calculation program 46 repeats the processes from s131 onwards to select that user. If there is no user who has not executed the processes of s203 and s2035, the influence calculation process s13 ends.

<Necessary generated energy amount prediction processing>
FIG. 13 is a flow chart for explaining the required generated energy amount prediction process s15. First, the required renewable energy amount prediction program 47 selects one user (s301).

The required renewable energy amount prediction program 47 predicts the power consumption of each user's individual part during the prediction period based on the current information on the equipment of the individual part (s303). Note that the prediction period is the period of the aggregation unit.

For example, the required renewable energy amount prediction program 47 calculates power consumption based on the performance information (configuration and power consumption of each device) received in s9.

The required renewable energy amount prediction program 47 calculates the required renewable energy P_RE for the individual portion of the user in the prediction period based on the conversion factor in the renewable energy management table 100 and the power consumption of the individual portion calculated in s303 ( prediction) (s305).

For example, the required renewable energy amount prediction program 47 refers to the renewable energy management table 100, acquires the value of the conversion factor 105 of the record related to the user, and calculates The required renewable energy P_RE for the individual portion of the user is calculated by multiplying the future power consumption of the individual portion thus obtained.

The required renewable energy amount prediction program 47 calculates the required renewable energy total amount by type (the initial value is set to 0 is set) is added to the required renewable energy P_RE for the user's individual portion calculated in s305 (s307).

Specifically, the required renewable energy amount prediction program 47 refers to the renewable energy management table 100 and acquires the requirement items 102 of the record related to the user. The required renewable energy amount prediction program 47 refers to the renewable energy procurement method type table 200 and identifies the type ID 201 of the record in which the acquired requirement item 102 is set in the available requirement 203 . The required renewable energy amount prediction program 47 adds P_RE calculated in s305 to the total required renewable energy amount by type related to the type ID.

The necessary renewable energy amount prediction program 47 calculates (predicts) the power consumption of individual parts of existing and new users in the prediction period based on the DC user equipment increase/decrease design plan table 700 (s309).

In the case of an existing user, for example, the required renewable energy amount prediction program 47 refers to the DC user equipment increase/decrease design plan table 700 and acquires a record in which the user is set as the user 701 . Then, the necessary renewable energy amount prediction program 47 selects each device of the increase/decrease plan 703 of the record in which the period specified from the implementation date of the increase/decrease plan 703 and the plan period 704 includes the prediction period among the acquired records is multiplied by the prediction period, and the multiplied values are totaled to predict the power consumption.

In the case of a new user, for example, the required renewable energy amount prediction program 47 acquires data on newly introduced equipment and its power consumption from the performance information received in s9 or a predetermined management table, so that the user Calculate the power consumption of the individual parts of

Note that the method of calculating power consumption described here is just an example, and the required renewable energy amount prediction program 47 may predict changes in power consumption due to changes in the configuration of individual parts.

Next, the required renewable energy amount prediction program 47 determines the power consumption of the user's individual part predicted in s309 and the degree of influence of the user calculated in the influence degree calculation process s13. , the power consumption of the common portion in the prediction period is predicted (s311). Specifically, the required renewable energy amount prediction program 47 calculates the power consumption of the common portion by multiplying the power consumption of the user's individual portion by the degree of influence of the user.

The required renewable energy amount prediction program 47 calculates (predicts) the required renewable energy P_RE_dc for the business operator in the prediction period based on the conversion factor in the renewable energy management table 100 and the power consumption of the common portion predicted in s311. (s313).

For example, the required renewable energy amount prediction program 47 refers to the renewable energy management table 100, acquires the value of the conversion factor 105 of the record related to the business operator, and calculates By multiplying by the power consumption of the common portion obtained above, the required renewable energy P_RE_dc of the business operator corresponding to the amount affected by the individual portion is calculated.

Next, the required renewable energy amount prediction program 47 calculates in s313 the required renewable energy total amount by type related to the type of procurement method of the business operator (the type of procurement method corresponding to the environmental requirements of the business operator) , the operator's required renewable energy P_RE_dc is added (s315).

Specifically, the required renewable energy amount prediction program 47 refers to the DC user environment requirement table 600 and acquires the requirement item 602 of the record related to the business operator. The required renewable energy amount prediction program 47 refers to the renewable energy procurement method type table 200 and identifies the type ID 201 of the record in which the acquired requirement item 602 is set in the available requirement 203 . The required renewable energy amount prediction program 47 adds P_RE_dc calculated in s313 to the total required renewable energy amount by type associated with the type ID.

The required renewable energy amount prediction program 47 confirms whether or not the processes of s301 to s315 have been executed for all users (s317). When the processes of s301 to s315 have been executed for all users (s317: Yes), the required renewable energy amount prediction program 47 executes the process of s319. If the processes of s301 to s315 have not been executed for all users (s317: No), the required renewable energy amount prediction program 47 repeats the process of s301 to select the users who have not executed the processes.

In s319, the required renewable energy amount prediction program 47 predicts the power consumption of the common portion (business-specific portion) during the prediction period.

For example, the required renewable energy amount prediction program 47 refers to the DC user equipment increase/decrease design plan table 700 and acquires a record in which the operator is set as the user 701 . Then, the necessary renewable energy amount forecasting program 47 determines, among the acquired records, the period specified by the implementation date of the increase/decrease plan 703 and the period specified by the plan period 704 includes the prediction period. By multiplying the power consumption by the prediction period, the power consumption of the common part in the prediction period is calculated.

Next, the required renewable energy amount prediction program 47 calculates the required renewable energy P_RE_dc0 of the common portion of the business operator in the prediction period based on the conversion factor in the renewable energy management table 100 and the power consumption of the common portion predicted in s319. is calculated (estimated) (s321).

Specifically, the required renewable energy amount prediction program 47 refers to the renewable energy management table 100, acquires the value of the conversion factor 105 of the record related to the business operator, and obtains the conversion factor 105 value of the business operator, The required renewable energy P_RE_dc0 of the business operator is calculated by multiplying by the power consumption of the common portion of the business operator calculated in s319.

Next, the required renewable energy amount prediction program 47 calculates in s321 the required renewable energy total amount by type related to the type of procurement method of the business operator (the type of procurement method corresponding to the environmental requirements of the business operator) , and the required renewable energy P_RE_dc0 for the common part of the operator (s323). Thus, the required energy amount prediction process s15 is completed.

Specifically, the required renewable energy amount prediction program 47 refers to the renewable energy management table 100 and acquires the requirement items 102 of the record related to the business operator. The required renewable energy amount prediction program 47 refers to the renewable energy procurement method type table 200 and identifies the type ID 201 of the record in which the acquired requirement item 102 is set in the available requirement 203 . The required renewable energy amount prediction program 47 adds P_RE_dc0 calculated in s321 to the total required renewable energy amount by type related to the type ID.

<Renewable energy excess/deficiency detection processing>
FIG. 14 is a flowchart illustrating details of the renewable energy excess/deficiency detection process s17. The renewable energy excess/deficiency detection program 48 selects one of the renewable energy procurement methods (s401).

The renewable energy excess/deficiency detection program 48 aggregates the procurement amount of renewable energy of the type selected in s401 during the prediction period (s403).

For example, the renewable energy excess/deficiency detection program 48 refers to the renewable energy procurement plan table 500, the forecast period is set to the planned procurement date 501, the type selected in s401 is set to the procurement method type ID 502, and the status 504 is set to The values of the procurement renewable energy amount 503 of all the records that are “procured” are acquired, and the acquired values are totaled. In addition, the renewable energy excess/deficiency detection program 48 may add a record whose status is "to be procured".

The renewable energy excess/deficiency detection program 48 compares the renewable energy procurement amount in the prediction period aggregated in s403 and the required renewable energy amount in the prediction period calculated in the required renewable energy amount prediction process s15, thereby determining the renewable energy is insufficient in the prediction period (s405).

For example, the renewable energy excess/deficiency detection program 48 determines whether or not the renewable energy procurement amount aggregated in s403 is less than the required renewable energy amount related to the selected type calculated in the required renewable energy amount prediction process s300. judge.

The renewable energy excess/deficiency detection program 48 checks whether or not the processes of s401 to s405 have been executed for all renewable energy procurement method types (s407). When the processes of s401 to s405 have been executed for all renewable energy procurement method types (s407: Yes), the renewable energy excess/deficiency detection process s17 ends. If there is a type of renewable energy procurement method for which the processes of s401 to s405 have not been executed (s407: No), the renewable energy excess/deficiency detection program 48 repeats the process of s401 to select that type.

<Renewable energy procurement plan creation process>
FIG. 15 is a flowchart for explaining the details of the renewable energy procurement plan creation process s21.

The renewable energy procurement plan creation program 49 selects one type of procurement method (s501).

The renewable energy procurement plan creation program 49 calculates the renewable energy procurement amount for the prediction period calculated in the renewable energy excess/deficiency detection process s17 and the required generated energy amount prediction process s15 for the type of procurement method selected in s501. , the difference from the total amount of required renewable energy for each type in the prediction period (s503).

The renewable energy procurement plan creation program 49 identifies the option with the lowest unit price in the type of procurement method selected in s501 (s505).

For example, the renewable energy procurement plan creation program 49 refers to the renewable energy management table 100 to identify the content of the procurement method type 104 of the record related to the business operator, and further refers to the renewable energy procurement method type table 200. All options of the procurement method 204 of the record related to the specified procurement method type 104 are acquired (for example, non-fossil certificate, green power certificate, VPPA, and in-house power generation). Then, the renewable energy procurement plan creation program 49 identifies the type of procurement method with the lowest unit price among the acquired procurement methods.

It should be noted that the renewable energy procurement plan creation program 49 may specify the type of procurement method using the monetary amount record related to the procurement amount 405 of the renewable energy procurement record table 400 . In addition, the renewable energy procurement plan creation program 49 may specify procurement method options based on criteria other than the unit price (for example, the option with the lowest procurement risk).

The renewable energy procurement plan creation program 49 creates a renewable energy procurement plan based on the processing results of s503 and s505 (s507).

For example, the renewable energy procurement plan creation program 49 creates a new record in the renewable energy procurement plan table 500, sets the forecast period to the planned procurement date 501, selects the selected procurement method option to the procurement method type ID 502, and selects the procurement renewable energy. The amount 503 is set to the difference calculated in s503, and the status 504 is set to "planned procurement".

The renewable energy procurement plan creation program 49 determines whether or not the processes of s501 to s507 have been executed for all procurement method types (s509). If the processes of s501 to s507 have been executed for all procurement method types (s509: Yes), the renewable energy procurement plan creation process s21 ends. If there is a type of procurement method for which the processes of s501 to s507 have not been executed, the renewable energy procurement plan creation program 49 repeats the process of s501 to select the type of procurement method.

A transition 1022 of the cumulative amount of energy is displayed. In addition, in the renewable energy information display column 1020, information 1023 on the timing and the amount of shortage of the procurement amount of renewable energy with respect to the demand amount of renewable energy is displayed.

In the procurement plan display column 1030, the cost 1031 related to the procurement of the shortage of renewable energy and the content 1032 of the renewable energy procurement plan are displayed.

<Renewable Energy Procurement Plan 2nd Preparation Process>
FIG. 17 is a diagram illustrating an example of processing for creating a second renewable energy procurement plan. This process is started, for example, when a new user decides to use the data center 60 .

First, the DC user terminal 20 used by the new user transmits a contract request regarding the use of the data center 60 to the DC operator management terminal 10 (s51).

Upon receiving the contract request, the DC operator management terminal 10 transmits information such as environmental requirements (information corresponding to the DC user environment requirement table 600) included in the received contract request to the DC user management server 50. (s53). The DC user management server 50 registers the received information in the DC user environment requirement table 600. FIG.

The subsequent processing from s1 to s17 is the same as the renewable energy procurement plan first creation processing. However, in the processes of s11 to s19, the DC operator management terminal 10 only performs processes related to new users.

In s19, the integrated DC management server 40 determines whether procurement of renewable energy is necessary for each type of procurement method specified in s11 based on the result of the renewable energy excess/deficiency detection process s17 (s19 ). If procurement of renewable energy is required (s19: YES), the integrated DC management server 40 executes the process of s55, and if procurement of renewable energy is not required (s19: NO), the integrated DC management server 40 executes the processing of s23, which is the same as the processing for creating the first renewable energy procurement plan.

In s55, the integrated DC management server 40 creates contract information with changed environmental requirements for the new user. For example, the integrated DC management server 40 changes the environmental requirements so as to eliminate the shortage of renewable energy calculated in s17 (for example, lowering the renewable energy rate, changing the do).

The integrated DC management server 40 transmits the contract information created in s55 to the new user's DC user terminal 20 via the DC operator management terminal 10 (s57).

The new user's DC user terminal 20 transmits a new contract request corresponding to the received contract information to the new user's information processing device via the DC operator's management terminal 10. (s59).

When the integrated DC management server 40 receives a new contract request, it executes the processes of s11 to s15 again (s61). After that, the integrated DC management server 40 executes the processing of s21, which is the same as the renewable energy procurement plan first creation processing. After that, the process of s23 is executed.

In addition, in this process, the integrated DC management server 40 changes the environmental requirements for the new contractor in s55, but changes the environmental requirements for other existing users or businesses, and furthermore The processing of s57 to s61 may be performed similarly.

Also, in s61, the integrated DC management server 40 may further perform the processes of s17 to s61 to confirm or re-determine that the required renewable energy is sufficient.
