以下において、第4実施形態について、第1実施形態との相違点を説明する。第4実施形態は、システム構成については第1実施形態と同様である。
第4実施形態では、電力制御装置150の制御部152は、太陽光発電装置130の余剰電力を検出する。余剰電力は、太陽光発電装置130の発電電力のうち、電力系統への逆潮流を行わない場合における、負荷120により消費されず、かつ蓄電池装置140に充電されない電力である。例えば、太陽光発電装置130は、通常はMPPT制御により最大発電力を確保するよう動作するが、最大発電電力が必要とされない場合にはMPPT制御を停止して出力電力を低下させる機能を有している。ここで、本来発電可能な電力値と、意図的に低下させた電力との差は、いわば抑制した電力であり、MPPT制御を行っていたならば余剰となる電力(余剰電力)でもある。よって、太陽光発電装置130がMPPT制御を行っているときと行っていないときとの出力差により、余剰電力を算出することができる。電力制御装置150の通信部151は、マルチDCリンククラスに対応するプロパティとして、太陽光発電装置130の余剰電力を機器制御装置200に通知する。
上述したように、第4実施形態では、電力制御装置150の通信部151は、マルチDCリンククラスに対応するプロパティとして、太陽光発電装置130の余剰電力を機器制御装置200に通知する。機器制御装置200の通信部210は、太陽光発電装置130の余剰電力を電力制御装置150から取得する。機器制御装置200の制御部220は、太陽光発電装置130の余剰電力を消費するように負荷120を制御する。
以下において、第5実施形態について、第1実施形態との相違点を説明する。第5実施形態は、システム構成については第1実施形態と同様である。
第5実施形態では、電力制御装置150の通信部151は、マルチDCリンククラスに対応するプロパティとして、蓄電池装置140の放電モードを機器制御装置200に通知する。放電モードは、負荷120の消費電力の増減に追従するように放電を行う負荷追従放電モードを含む。機器制御装置200の通信部210は、蓄電池装置140の放電モードを電力制御装置150から取得する。
上述したように、第5実施形態では、電力制御装置150の通信部151は、マルチDCリンククラスに対応するプロパティとして、蓄電池装置140の放電モードを機器制御装置200に通知する。放電モードは、負荷120の消費電力の増減に追従するように放電を行う負荷追従放電モードを含む。機器制御装置200の通信部210は、蓄電池装置140の放電モードを電力制御装置150から取得する。
以下において、第6実施形態について、第1実施形態との相違点を説明する。第6実施形態は、システム構成については第1実施形態と同様である。
第6実施形態では、電力制御装置150の通信部151は、マルチDCリンククラスに対応するプロパティとして、蓄電池装置140の充電モードを機器制御装置200に通知する。充電モードは、太陽光発電装置130の余剰電力のみを充電する余剰充電モードを含む。
上述したように、第6実施形態では、電力制御装置150の通信部151は、マルチDCリンククラスに対応するプロパティとして、蓄電池装置140の充電モードを機器制御装置200に通知する。充電モードは、太陽光発電装置130の余剰電力のみを充電する余剰充電モードを含む。機器制御装置200の通信部210は、蓄電池装置140の充電モードを電力制御装置150から取得する。
上述した第4実施形態では、太陽光発電装置130の余剰電力が、マルチDCリンククラスに対応するプロパティであるケースを例示した。しかしながら、太陽光発電装置130の余剰電力は、住宅用太陽光発電クラスに対応するプロパティであってもよい。
