Abstract
Description
(電力管理システム)
以下において、実施形態に係る電力管理システムについて説明する。
以下において、実施形態に係る制御装置について説明する。図2に示すように、制御装置(EMSコントローラ160)は、通信部161と、管理部162と、制御部163とを有する。
以下において、実施形態に係る機器について説明する。機器500は、EMSコントローラ160によって制御される機器であればよく、太陽電池110、蓄電池120、PCS130又は負荷150である。図3に示すように、機器500は、通信部510と、制御部520とを有する。
以下において、実施形態に係る管理方法について説明する。図4では、機器500として、機器500A~機器500Dが例示されている。
実施形態では、EMSコントローラ160は、電力供給が再開した再開状態において、インスタンスリストの送信を要求する要求コマンドを未受信機器に送信する。すなわち、EMSコントローラ160は、未送信機器からブロードキャスト又はマルチキャストにて送信されたインスタンスリストの受信に失敗した場合であっても、要求コマンドによってインスタンスリストの取得を試みる。このような動作によってインスタンスリストを取得できた場合には、未受信機器を利用することができるため、システム全体として利便性が向上する。さらに、EMSコントローラ160は、このような動作によってインスタンスリストを取得できなかった場合に限って未受信機器を利用することができないと判定するため、未受信機器を利用することができるか否かの判断精度を向上することができる。
以下において、実施形態の変更例1について説明する。以下においては、実施形態に対する相違点について主として説明する。
本発明は上述した実施形態によって説明したが、この開示の一部をなす論述及び図面は、この発明を限定するものであると理解すべきではない。この開示から当業者には様々な代替実施形態、実施例及び運用技術が明らかとなろう。
