本発明によれば、再生可能エネルギーにより発電された電力を効率的かつ有効に利用する技術を提供することができる。 According to the present invention, it is possible to provide a technique for efficiently and effectively using electric power generated by renewable energy.

本発明に係る電力運用システムの構成の一例を示す図である。1 is a diagram showing an example of the configuration of a power operation system according to the present invention.

以下、本発明の電力運用システムの構成の一例について、図面を用いて説明する。実線矢印は情報の流れを示す。破線矢印は電気の流れを示す。 An example of the configuration of the power operation system of the present invention will be described below with reference to the drawings. Solid arrows indicate the flow of information. Dashed arrows indicate the flow of electricity.

図1の電力運用システムは、ユーザサイトUSと、情報処理部Vとを有する。 The power operation system in FIG. 1 includes a user site US and an information processing section V.

「ユーザサイトUS」とは、再生可能エネルギー発電設備により発電された電力が一旦蓄積される場所を意味する。以下、ユーザサイトUSで蓄電されることを「再エネ蓄電」ともいう。
ユーザサイトUSには、再生可能エネルギー発電設備Pにより発電された電力を蓄える蓄電設備Bと、前記蓄電設備Bの制御及び管理をする管理設備2とを有する。
"User site US" means a place where electric power generated by renewable energy power generation equipment is temporarily stored. Hereinafter, storing power at the user site US will also be referred to as "renewable energy storage."
The user site US includes a power storage facility B that stores power generated by the renewable energy power generation facility P, and a management facility 2 that controls and manages the power storage facility B.

再生可能エネルギー発電設備Pは、再生可能エネルギーを用いて発電をする。ここで、再生可能エネルギー発電設備Pは、図1ではユーザサイトUSに設置されているが、ユーザサイトUSの必須な構成要素ではなく、ユーザサイトUSの外部に設置され、蓄電設備Bと送電線等により接続されるようにしてもよい。再生可能エネルギー発電設備Pとして、太陽光発電設備、風力発電設備、水力発電設備、バイオマス発電設備、地熱発電設備等が挙げられる。 Renewable energy power generation facility P generates power using renewable energy. Here, although the renewable energy power generation facility P is installed at the user site US in FIG. 1, it is not an essential component of the user site US, but is installed outside the user site The connection may be made by, for example, Examples of renewable energy power generation equipment P include solar power generation equipment, wind power generation equipment, hydroelectric power generation equipment, biomass power generation equipment, geothermal power generation equipment, and the like.

蓄電設備Bは、再生可能エネルギー発電設備Pにより発電された電力を蓄える機能を有する設備である。蓄電設備Bは、例えば蓄電池として構成されてもよいし、蓄電池を有する装置や機械(例えば、電気自動車)として構成されてもよいし、揚水発電であってもよい。
ここで、蓄電池は、特に限定されず任意なものを採用することができる。例えば、リチウムイオン電池、ナトリウム―硫黄電池(NAS電池)、全固体電池、レドックスフロー電池(以下、「RFB」ともいう。)等を採用することができる。
蓄電設備Bとして、RFBを採用することが好ましい。RFBを採用することで、後述の管理設備2は、RFBの電解液の量、活物質の種類、活物質の濃度、及び活物質の価数等の情報を取得して、これらの情報に基づいて供給できる電力量を含む蓄電情報をリアルタイムに取得することが容易となる。
The power storage facility B is a facility that has a function of storing power generated by the renewable energy power generation facility P. The power storage facility B may be configured, for example, as a storage battery, a device or machine (for example, an electric vehicle) having a storage battery, or a pumped storage power generation system.
Here, the storage battery is not particularly limited and any suitable storage battery can be used. For example, a lithium ion battery, a sodium-sulfur battery (NAS battery), an all-solid-state battery, a redox flow battery (hereinafter also referred to as "RFB"), etc. can be employed.
As the power storage equipment B, it is preferable to employ RFB. By adopting RFB, the management equipment 2 described below can acquire information such as the amount of electrolyte in RFB, the type of active material, the concentration of active material, and the valence of active material, and based on this information. It becomes easy to obtain power storage information including the amount of power that can be supplied in real time.

管理設備2は、蓄電設備Bに対する制御及び管理(例えば充放電制御や蓄電情報のリアルタイム取得)を行うと共に、情報処理部Vとの間で各種情報の授受を行う。具体的には、管理設備2は、ユーザサイトUSを識別可能な情報を含むユーザサイト情報と、蓄電設備Bの供給できる電力の量(以下「供給できる電力量」という)を含む蓄電情報とを情報処理部Vに送付する。ここで、供給できる電力量とは、蓄電設備Bから取り出せる全電力量のことであってもよく、蓄電設備Bから取り出せる全電力量からユーザサイトUSのユーザUが利用する予定の電力量が除かれた余剰電力量のことであってもよい。ここで、蓄電設備Bから取り出せる全電力量は管理設備2により推定されるリアルタイム値である。例えば、蓄電設備Bがレドックスフロー電池であれば、管理設備2は、活物質の平均価数をリアルタイムに測定し、前記平均価数、電解液の量、活物質の種類とその濃度及びレドックスフロー電池の充放電効率に基づいて、レドックスフロー電池の取り出せる全電力量をリアルタイムに推定することができる。ユーザUが利用する予定の電力量は管理設備2で設定する(例えばユーザUが入力する)ことができる。
ユーザサイトUSの識別情報は、例えば、再生可能エネルギー発電設備P、蓄電設備B、及び管理設備2の夫々の装置を一意に識別可能な情報(装置のID情報等)として挙げられる。
蓄電情報は、供給できる電力量の他、蓄電設備Bの空き容量情報(蓄電設備Bの蓄電可能な電力総量から取り出せる全電力量を差し引いた電力量)、蓄電設備Bの位置情報、再生可能エネルギー発電設備Pの発電量情報、電力供給計画情報、電力の供給に関する料金情報(例えば、電力供給単価 X円/kWh)等をさらに含むようにすることができる。ここで、電力供給計画情報は、例えば、いつ、どのぐらいの電力を供給できる等が挙げられる。
The management equipment 2 controls and manages the power storage equipment B (for example, charge/discharge control and real-time acquisition of power storage information), and also exchanges various information with the information processing unit V. Specifically, the management equipment 2 stores user site information including information that allows identification of the user site US, and power storage information including the amount of power that the power storage equipment B can supply (hereinafter referred to as "supplyable power amount"). Send to information processing department V. Here, the amount of power that can be supplied may refer to the total amount of power that can be extracted from power storage equipment B, and the amount of power that is scheduled to be used by user U of user site US is excluded from the total amount of power that can be taken out from power storage equipment B. It may also refer to the amount of surplus electricity generated. Here, the total amount of power that can be taken out from power storage equipment B is a real-time value estimated by management equipment 2. For example, if power storage equipment B is a redox flow battery, the management equipment 2 measures the average valence of the active material in real time, and measures the average valence, the amount of electrolyte, the type of active material and its concentration, and the redox flow. Based on the charging and discharging efficiency of the battery, the total amount of power that can be extracted from the redox flow battery can be estimated in real time. The amount of power that the user U plans to use can be set in the management equipment 2 (for example, inputted by the user U).
The identification information of the user site US is, for example, information that can uniquely identify each of the renewable energy power generation equipment P, the power storage equipment B, and the management equipment 2 (device ID information, etc.).
In addition to the amount of power that can be supplied, the power storage information includes information on the free capacity of power storage facility B (the amount of power obtained by subtracting the total amount of power that can be extracted from the total amount of power that can be stored in power storage facility B), location information of power storage facility B, and renewable energy. It is possible to further include power generation amount information of the power generation facility P, power supply plan information, price information regarding power supply (for example, power supply unit price X yen/kWh), etc. Here, the power supply plan information includes, for example, when and how much power can be supplied.

また、管理設備2は、情報処理部Vからの放電指示に基づいて、蓄電設備Bから電力を所定の送配電網Gに送り出すように、蓄電設備Bを放電させる制御を実行することもできる。ここで、送配電網Gは、複数の送電線、配電線、変電所等により構成されていてもよく、蓄電設備Bと電力需要家とをつなぐ一本の電線のみで構成されていてもよい。 Furthermore, the management equipment 2 can also perform control to discharge the power storage equipment B, based on a discharge instruction from the information processing unit V, so that power is sent from the power storage equipment B to a predetermined power transmission and distribution network G. Here, the power transmission and distribution network G may be composed of multiple power transmission lines, distribution lines, substations, etc., or may be composed of only one electric wire connecting the power storage facility B and the power consumer. .

情報処理部Vは、ユーザサイトUSの管理設備2から送付されてきたユーザサイト情報を識別して、前記ユーザサイトUSから供給された電力が再生エネルギー発電設備Pより発電された電力であることを認証する(以下、「再エネ証明」ともいう)機能を有する。
また、情報処理部Vは、後述する電力需要家により送付されてきた電力需要要求を受信して、電力需要要求と、前記再エネ証明されたユーザサイト情報及び蓄電情報とを何等かの基準に基づいて、マッチングさせる機能を有する。
更に、情報処理部Vは、前記マッチング結果に基づいて、蓄電設備Bに対する放電指示を生成し、前記放電指示を管理設備2に送付する機能を有する。管理設備2は、情報処理部Vからの放電指示に基づいて、蓄電設備Bから電力を所定の送配電網Gに送り出すように、蓄電設備Bを放電させる。
The information processing unit V identifies the user site information sent from the management facility 2 of the user site US, and determines that the power supplied from the user site US is the power generated by the renewable energy power generation facility P. It has a function of authentication (hereinafter also referred to as "renewable energy certification").
Further, the information processing unit V receives a power demand request sent by a power consumer, which will be described later, and compares the power demand request, the renewable energy-certified user site information, and the power storage information with some criteria. It has a matching function based on
Further, the information processing unit V has a function of generating a discharge instruction for the power storage equipment B based on the matching result and sending the discharge instruction to the management equipment 2. Based on the discharge instruction from the information processing unit V, the management equipment 2 discharges the power storage equipment B so that power is sent from the power storage equipment B to a predetermined power transmission and distribution network G.

情報処理部Vは、上記機能を実現できるものであれば、特に限定されない。情報処理部Vは、例えば、再エネ証明を含む情報処理を集中管理用のサーバで行う集中管理形態や、集中管理用サーバを使わず、ネットワークを利用して情報処理をブロックチェーン技術(分散台帳管理技術を含む)により行う分散管理形態や、前記2つの形態を利用する併用管理形態とすることができる。併用形態を採用する場合、例えば、再エネ証明はブロックチェーン技術により通信ネットワークで行われ、他の情報処理(例えば、マッチング)は集中管理用サーバにより行われるようにすることができる。 The information processing section V is not particularly limited as long as it can realize the above functions. For example, the information processing unit V may adopt a centralized management format in which information processing including renewable energy certification is performed on a centralized management server, or use blockchain technology (distributed ledger) to perform information processing using a network without using a centralized management server. It is possible to adopt a distributed management format using a management technology (including management technology), or a combined management format using the above two methods. When a combination mode is adopted, for example, renewable energy certification can be performed in a communication network using blockchain technology, and other information processing (for example, matching) can be performed by a central management server.

集中管理用サーバは、汎用性を有する情報処理装置で構成されることができる。通信ネットワークは、少なくとも複数のユーザサイトUSのデータを保存可能な設備(例えば、管理設備2や、管理設備2と別のデータ管理及び通信ができる設備)が有線通信又は無線通信により互いに接続されるように構成されたネットワークを一例として挙げられる。ブロックチェーン技術を採用して、情報処理を行うことは、中央集権管理形態と比べて記録の喪失や改竄等に対して安全性が高くなり、更にシステム導入コストや利用運用にかかわるコストが削減できるという利点がある。 The central management server can be configured with a versatile information processing device. In the communication network, equipment capable of storing data of at least a plurality of user sites US (for example, management equipment 2 and equipment capable of data management and communication separate from management equipment 2) are connected to each other by wired or wireless communication. An example of this is a network configured as follows. Adopting blockchain technology for information processing is more secure against loss or falsification of records than a centralized management system, and can further reduce system installation costs and costs related to usage and operation. There is an advantage.

電力需要家は、再エネ証明された電力を利用したい又は取り扱いたい者や施設や建物であればよく、特に限定されない。例えば、再エネ証明された電力を利用したい住宅、工場、ビル、商店、病院、充電ステーション等、又はそれらの施設や建物の利用者、再エネ証明された電力を取り扱いたい電力会社が例として挙げられる。 The electric power consumer is not particularly limited, and may be any person, facility, or building who wants to use or handle electric power certified as renewable energy. Examples include residences, factories, buildings, shops, hospitals, charging stations, etc. that wish to use electricity that has been certified as renewable energy, users of these facilities and buildings, and electric power companies that wish to handle electricity that has been certified as renewable energy. It will be done.

電力需要要求は、電力需要量要求、電力の給電開始時刻や終了時刻等の情報、電力需要計画情報(計画電力需要時間要求、計画電力需要量要求等を含む)、電力の使用に関する料金情報、電力需要家の識別情報、電力需要家の位置情報等の情報から選択することができ、必要に応じて複数を組み合わせて選択しても構わない。
情報処理部Vにおいて、電力需要要求と、前記再エネ証明されたユーザサイト情報及び前記蓄電情報とのマッチングを行う。マッチングの方法は種々あるが、例えば、情報処理部Vが、それぞれのユーザサイトUSから受信した蓄電情報に含まれる供給できる電力量情報を、電力需要家からの電力需要要求に含まれる電力需要量情報とマッチングさせて、供給できる電力量が電力需要量を満たすことができるユーザサイトUSを抽出する。このとき抽出されるユーザサイトUSは1つでも良いし、供給できる電力量を合計することで電力需要量を満たすことができる1以上のユーザサイトUSを抽出しても良い。或いは、別のマッチング方法として、情報処理部Vが、ユーザサイト情報に含まれたユーザサイトUSの識別情報と、電力需要家の識別情報をマッチングさせて、ユーザサイトUSを抽出する。具体的な例として、特定のユーザサイトUS群の識別情報と、特定の電力需要家群の識別情報とをリンクさせて、前記特定の電力需要家群から送付されてきた電力需要要求に合致する条件のユーザサイトUSを、優先的に前記特定のユーザサイトUS群からを抽出する。或いは、情報処理部Vは、ユーザサイトUSの電力の供給に関する料金情報と、電力需要家の電力の使用に関する料金情報に基づいたマッチングを行い、電力需要家の料金情報に合致するユーザサイトUSを抽出することもできる。或いは、情報処理部Vは、蓄電設備Bの位置情報と、電力需要家の位置情報を基に、蓄電設備Bと電力需要家の位置が近い順にマッチングさせて、ユーザサイトUSを抽出する。なお、上記のマッチングを一つのみ行ってもよく、同時に又は優先順位を付けて、複数のマッチングを行ってもよい。
The power demand request includes power demand amount request, information such as power supply start time and end time, power demand plan information (including planned power demand time request, planned power demand amount request, etc.), rate information regarding power usage, The information can be selected from information such as the identification information of the power consumer and the location information of the power consumer, and a combination of a plurality of information may be selected as necessary.
The information processing unit V matches the power demand request with the renewable energy certified user site information and the power storage information. There are various matching methods, but for example, the information processing unit V may match the supplyable power amount information included in the power storage information received from each user site US to the power demand amount included in the power demand request from the power consumer. By matching the information, a user site US whose supplyable power can meet the power demand is extracted. At this time, only one user site US may be extracted, or one or more user sites US that can satisfy the power demand by summing up the amount of power that can be supplied may be extracted. Alternatively, as another matching method, the information processing unit V matches the identification information of the user site US included in the user site information with the identification information of the power consumer to extract the user site US. As a specific example, the identification information of a specific user site US group and the identification information of a specific power consumer group may be linked to match the power demand request sent from the specific power consumer group. A user site US of the condition is preferentially extracted from the specific user site US group. Alternatively, the information processing unit V performs matching based on the rate information regarding the power supply of the user site US and the rate information regarding the power usage of the power consumer, and selects the user site US that matches the rate information of the power consumer. It can also be extracted. Alternatively, the information processing unit V extracts the user site US by matching the power storage facility B and the power consumer in order of their location based on the location information of the power storage facility B and the location information of the power consumer. Note that only one of the above matchings may be performed, or a plurality of matchings may be performed simultaneously or in a prioritized manner.

情報処理部Vは、マッチングで抽出されたユーザサイトUSの管理設備2に対して、放電指示を生成して、送付する。管理設備2は、情報処理部Vからの放電指示に基づいて、蓄電設備Bから所定の送配電網Gに所定の電力を送り出すように、蓄電設備Bを放電させる。 The information processing unit V generates and sends a discharge instruction to the management facility 2 of the user site US extracted by matching. Based on the discharge instruction from the information processing unit V, the management equipment 2 discharges the power storage equipment B so that a predetermined amount of power is sent from the power storage equipment B to a predetermined power transmission and distribution network G.

このような図1の例の電力運用システムでは、例えば次のような一連の処理が実行される。
ステップSS11において、管理設備2は、ユーザサイト情報と蓄電情報とを情報処理部Vに送付する。
ステップSS12において、管理設備2から送付されてきたユーザサイト情報と蓄電情報とは、情報処理部Vにおいて再エネ証明及び管理される。
