Description
<概要>
図1は、実施形態1に係るグリッド統合制御装置2000を、その使用環境と共に示した図である。グリッド統合制御装置2000は、各グリッド3000の電力需要を満たすように、グリッド3000間における電力の送電を制御する。ここで図1において、実線の矢印はデータの流れを表し、点線の矢印は電力の流れを表す。
グリッド3000は、配電部3030を複数有していてもよい。
需給電力量情報は、例えば図2に示す需給電力量テーブル100によって表される。需給電力量テーブル100は例えば、グリッドID102及び、グリッドID102が示すIDのグリッド3000における需給電力量を表す需給電力量104を有する。以下、グリッドIDがiのグリッド3000を、グリッド3000-iと表記する。需給電力量は、グリッド3000の供給電力量と需要電力量の差を示す。そのため、例えば需給電力量104の値が正の値の場合は供給電力量が需要電力量より多いことを表し、需給電力量104の値が負の値の場合は需要電力量が供給電力量より多いことを表す。例えば図2の場合は、グリッド3000-1は100kWh、グリッド3000-3は200kWh、それぞれ供給電力量が需要電力量より多い。一方グリッド3000-2は、需要電力量が供給電力量より300kWh多い。
コスト情報は、例えば図3に示すコストテーブル200で表される。コストテーブル200は例えば、送電線5000の片側のグリッド3000のIDであるグリッド1ID202、送電線5000のもう一方側のグリッド3000のIDであるグリッド2ID204、及びグリッド1ID202が示すグリッドとグリッド2ID204が示すグリッドを結ぶ送電線5000を利用した送電にかかるコストを示すコスト206を有する。コスト206は例えば、送電線5000を介して1Wの電力を1時間送電するためのコストを示す。
グリッド制御指示生成部2020からグリッド制御部3020へ送信するグリッド制御指示は、グリッド3000が電力を送電する送電先のグリッド3000と、グリッド3000へ送電する電力量の組み合わせを有する。これは、例えば図4に示す送電制御テーブル300で表される。送電制御テーブル300は例えば、送電先のグリッド3000のIDを示すグリッドID302、グリッドID302が示すグリッド3000へ送電する送電電力量を示す送電電力量304を有する。
グリッド間の送電電力量を決定する方法は例えば、以下の数式1で表される線形計画問題1を満たす送電電力Pl(i,j)を求める方法である。ここでPl(i,j)は、グリッド3000-iからグリッド3000-jへ送電する電力の大きさである。グリッド3000がグリッド統合制御装置2000の制御に従って送電を行う時間の長さをTpとすると、グリッド3000-iからグリッド3000-jへ送電する送電電力量は、Pl(i,j)・Tpで表される。下記線形計画問題1を解くことで、送電線5000を介した電力の送電にかかるコストが最小になる送電電力量が定まる。
図5は、グリッド制御指示生成部2020が行う、グリッド制御指示生成処理の流れを示している。
グリッド制御部3020は、グリッド制御指示生成部2020から受信するグリッド制御指示に従って送受電部3050を制御し、Tp時間内に他のグリッド3000へ電力を送電する。送電制御指示が送電制御テーブル300で表される場合、送電制御テーブル300の各レコードを参照し、IDがグリッドID302であるグリッド3000へ、送電電力量304に示される電力量の電力を送電する。
以上の構成により、本実施形態によれば、各グリッド3000の需給電力量情報及び各送電線5000のコスト情報に基づいて、グリッド3000の需要を満たすという条件の下、送電にかかる総コストを小さくするようにグリッド3000の送電を制御することで、グリッド3000間の送電にかかるコストを小さくすることができる。

図6は、実施形態2に係るグリッド統合制御装置2000を、その使用環境と共に示した図である。ここで図6において、図1と同符号が割り当てられている機能ブロックは、特に説明しない限り、図1の機能ブロックと同じ機能を有するとし、説明を省略する。また矢印の意味は、図1と同様である。
時系列需給電力量情報は、2つ以上の複数の時間帯それぞれについて、各グリッド3000の需給電力量を示す。時系列需給電力量情報は例えば、図7に示す時系列需給電力量―ブル400で表される。時系列需給電力量テーブル400は例えば、グリッドID402、各時間帯における需給電力量(時間帯1の需給電力量404、時間帯2の需給電力量406など)で構成される。
蓄電情報は、蓄電部3040の現在の蓄電電力量を示す。蓄電情報は例えば、図8に示す蓄電電力量テーブル500で表される。蓄電電力量テーブル500は例えば、蓄電部3040を特定するグリッドID502及び蓄電部ID504、及び蓄電部3040の現在の蓄電電力量を示す蓄電電力量506を有する。
適正範囲情報は、蓄電部3040の蓄電電力量の適正範囲を示す。蓄電部3040の蓄電電力量は、蓄電部3040の定格容量以下である必要がある。さらに蓄電部3040の蓄電電力量は、グリッド3000が需要家7000や他のグリッド3000へ供給できる電力量が予期せず増減する場合を想定して決定することが望ましい。まず、グリッド3000が供給可能な電力量が想定よりも多くなり、余剰電力が発生する場合に備え、蓄電部3040の蓄電電力量の上限値を定格容量よりも小さく設定しておくことが望ましい。これにより、上記余剰電力を蓄電部3040に蓄電することができるため、電力の無駄を少なくできる。そして、グリッド3000が供給可能な電力量が想定よりも少なくなる場合に備えるために、蓄電部3040の蓄電電力量の下限値を設定しておくことが望ましい。こうすることで、グリッド3000が受電する電力だけでは電力が不足する場合に、蓄電部3040から電力を供給することで、電力需要を満たすことができる。
グリッド制御部3020は、グリッド統合制御装置2000から受信するグリッド制御指示に従い、送受電部3050から蓄電部3040へ電力を送電して蓄電部3040を充電し、又は蓄電部3040から電力を放電して送受電部3050へ送電する。グリッド制御指示は例えば図10が示す充放電制御テーブル700を有する。充放電制御テーブル700は例えば、ある時間帯において、蓄電部ID702が示す蓄電部3040に充放電する電力量を表す充放電電力量704を有する。例えばグリッド制御部3020は、充放電電力量704が正の値場合は蓄電部3040へ電力を充電し、充放電電力量704が負の値の場合は蓄電部3040から電力を放電する。
グリッド3000間の送電電力量、及び蓄電部3040の充放電電力量を決定する具体的な方法は例えば、以下の数式2で表される線形計画問題2を満たすPl(t,i,j)及びE(t,i,j)を求める方法である。Pl(t,i,j)は、時間帯tにおいてグリッド3000-iからグリッド3000-jへ送電する電力の大きさを表す。E(t,i,j)は、時間帯tの開始時における、グリッド3000-iが有する蓄電部IDがjの蓄電部3040(以下、蓄電部3040-i-j)の蓄電電力量を表す。時間帯tにおける充放電電力量は、時間帯t+1における蓄電電力量E(t+1,i,j)から、時間帯tにおける蓄電電力量E(t,i,j)を引くことで求まる。線形計画問題2を解くことで、全ての時間帯tにおいて、グリッド3000の電力需要を満たし、かつ蓄電部3040の蓄電電力量を適正範囲内にするという条件の下、送電にかかるコストを最小にするグリッド3000間の送電電力量及び蓄電部3040の充放電電力量が求まる。なお線形計画問題2の各数式中の記号の内、線形計画問題1に同記号のものがあるものは、線形計画問題1における記号と同じ意味を表す。
グリッド制御部3020は、グリッド制御指示生成部2020から受信するグリッド制御指示に従い、送受電部3050と蓄電部3040を制御する。前述したように、本実施形態における送電制御指示は例えば、充放電制御テーブル700と送電制御テーブル300で表される。ここで、送電制御テーブル300に従った送電処理は実施形態1と同様であるため、説明を省略する。
以上の構成から、本実施形態によれば、少なくとも1つ以上のグリッド3000が1つ以上の蓄電部3040を有する場合において、各グリッド3000の電力需要を満たしつつ、さらに全ての蓄電部3040の蓄電電力量が適正範囲内であるという条件も満たした上で、送電にかかるコストを小さくできる。蓄電部3040の蓄電電力量を適正範囲内にすることで、グリッド3000による需要家7000や他のグリッド3000への電力供給が不足することを防ぎ、また、グリッド3000が受電した電力を消費しきれずに電力が無駄になることを防ぐ。
<概要>
図12は、実施形態3に係るグリッド統合制御装置2000を、その使用環境と共に示した図である。ここで図12において、図1又は図6と同符号が割り当てられている機能ブロックは、特に説明しない限り、図1又は図6記載の機能ブロックと同じ機能を有するとし、説明を省略する。また、矢印の意味は図1及び図6と同じである。
発電情報は、発電部3060による発電電力量を示し、例えば図13に示す発電電力量テーブル800で表される。発電電力量テーブル800は例えば、グリッドID802及び発電電力量804を有する。ここで、グリッド3000-iが発電部3060を複数有する場合は例えば、複数の発電部3060の発電電力量の合計を、グリッド3000-iにおける発電電力量とする。
発電情報履歴は、各時間帯における発電部3060の発電電力量の履歴を示し、例えば図14に示す発電電力量履歴テーブル900で表される。発電電力量履歴テーブル900は例えば、グリッドID902、及び時間帯ごとの発電電力量(時間帯1の発電電力量904、時間帯2の発電電力量906など)を有する。
発電部3060の発電電力量に基づいて蓄電部3040の蓄電電力量を決定する方法は例えば、発電部3060の発電電力量が増加した場合は、発電部3060と同じグリッド3000に属する蓄電部3040の蓄電電力量の適正範囲の上限値を小さくし、発電部3060の発電電力量が減少した場合は、発電部3060と同じグリッド3000に属する蓄電部3040の蓄電電力量の下限値を大きくする方法である。発電部3060の発電電力量が増加した場合に蓄電部3040の蓄電電力量を少なくすることで、発電部3060の発電電力量が増加し続けた場合に、発電部3060が発電した電力を蓄電部3040へ蓄えられるようにしておく。こうすることで、発電した電力を消費しきれずに電力の無駄が発生することを防ぐ。また、発電部3060の発電電力量が減少した場合に蓄電部3040の蓄電電力量を多くすることで、発電部3060の発電電力量が減少し続けた場合に、蓄電部3040からより多くの電力を補えるようにしておく。こうすることで、電力不足になることを防ぐ。
図15は、適正範囲決定部2120が蓄電部3040の蓄電電力量の適正範囲を決定する処理の流れを表している。
以上の構成から、本実施形態によれば、少なくとも1つ以上のグリッド3000が1つ以上の蓄電部3040を有する場合において、各グリッド3000の電力需要を満たしつつ、さらに全ての蓄電部3040の蓄電電力量が適正範囲内であるという条件も満たした上で、送電にかかるコストを小さくできる。蓄電部3040の蓄電電力量を適正範囲内にすることで、グリッド3000が電力不足になることを防ぎ、また、発電部3060が発電した電力を蓄えきれずに電力が無駄になることを防ぐ。さらに、発電部3060による発電電力量の変化に追従して蓄電部3040の蓄電電力量の適正範囲を変更することで、発電部3060の発電電力量が予期せず変化した場合に、電力の無駄及び電力不足が発生することを防ぐことができる。
<概要>
図16は、実施形態4に係るグリッド統合制御装置2000を、その使用環境と共に示す図である。ここで図16において、図1、図6又は図12に記載の機能ブロックと同符号の機能ブロックは、特に説明しない限り、図1、図6又は図12に記載の機能ブロックと同様の機能を有するとし、説明を省略する。また、図16におけるグリッド3000の内部構成は例えば、図6又は図12におけるグリッド3000の内部構成と同じである。そのため、図16において、グリッド3000の内部構成は省略する。
需要電力量取得部2160が需要電力量を取得する方法、及び供給電力量取得部2180が供給電力量を取得する方法は様々である。例えば、グリッド統合制御装置2000の管理者が手動で入力する方法がある。また、需要電力量と供給電力量が、電力供給者と電力消費者の間における売買契約に基づくものである場合は、その売買契約を管理する外部のサーバから取得する方法も考えられる。需要電力量については、需要電力量が配電部3030から需要家7000へ配電される電力量に基づいて定められる場合は、配電部3030から取得する方法も考えられる。供給電力量については、供給電力量が発電部3060によって発電される電力量に基づいて定められる場合は、発電部3060から発電電力量を取得する方法も考えられる。
以上の構成により、本実施形態によれば、各グリッド3000の需給電力量情報及び各送電線5000のコスト情報に基づいて、グリッド3000の需要を満たすという条件の下、送電にかかる総コストを小さくするようにグリッド3000の送電を制御することで、グリッド3000間の送電にかかるコストを小さくすることができる。また、グリッド統合制御装置2000が需給電力量を算出する機能を有するため、管理者や外部装置が需給電力量を算出する必要がなくなり、グリッド統合制御装置2000をより容易に利用できるようになる。

図17は、実施形態5に係るグリッド制御システム8000をその使用環境と共に示した図である。ここで、図17において図1、図6又は図16と同符号の機能構成部は、それらの図に記載されている同符号の機能構成部と同様の機能を有するため、説明を省略する。また、図が煩雑になることを避けるため、グリッド3000及びグリッド制御装置6000の組み合わせは1つだけ表記する。
以上の構成により、本実施形態によれば、グリッド制御システム8000において、グリッド制御装置6000はグリッド3000の需給電力量を算出してグリッド統合制御装置2000へ通知し、グリッド統合制御装置2000はグリッド制御装置6000から受信した需給電力量とコスト情報取得部2050が取得するコスト情報に基づき、グリッド3000の需要を満たすという条件の下、送電にかかる総コストを小さくするようにグリッド3000の送電を制御することで、グリッド3000間の送電にかかるコストを小さくすることができる。
