本開示の説明に先立ち、本開示に至った経緯について図1及び図2を参照しながら説明する。まずは、バーチャルパワープラント(VPP)の概要について、図1を参照しながら説明する。図1は、比較例に係る電力融通システム1001の概要を示す図である。
以下、本実施の形態に係る電力融通方法等について、図3~図12を参照しながら説明する。
まずは、電力融通システムの構成について、図3を参照しながら説明する。図3は、本実施の形態に係る電力融通システム1の機能構成を示す図である。本実施の形態に係る電力融通システム1は、複数の需要家を1つのグループ(コミュニティ)として、複数のグループ全体の電力需給バランスを調整するために、互いに異なるグループの需要家同士が電力を融通することを可能とするエネルギー管理システムである。電力融通システム1は、蓄電池を搭載する電動車両100を用いて電力を融通するエネルギー管理システムであるとも言える。なお、本実施の形態に係る電力融通システム1の概要は図1と同様であり、以下において図1に示すリソースアグリゲーターA~Cと、需要家A1~A3、B1~B3及びC1~C3とを用いて説明する。
上記のように構成される電力融通システム1の動作について、図5~図12を参照しながら説明する。図5は、本実施の形態に係る電力融通システム1の動作(電力融通方法)の一例を示すフローチャートである。具体的には、図5は、サーバ装置10Aの動作を示す。なお、図5では、リソースアグリゲーターAの需要家に電力需給の逼迫が発生しており、リソースアグリゲーターB及びCのそれぞれの需要家から電力の供給を受ける例について説明するが、リソースアグリゲーターB及びCの一方の需要家からのみ電力の供給を受けてもよい。電力の供給を受けることは、電力を融通することの一例である。
以上、本開示に係る電力融通方法等について、上記実施の形態に基づいて説明したが、本開示は、上記実施の形態に限定されるものではない。
