Description
(1)上記実施形態では、宅間電圧送信装置60が、宅間配線80の電圧を測定し、コントロールユニット7は測定された電圧値に基づいて売電電圧を変換するため、売電電圧と宅間配線80の電圧との差を小さく設定することができる。従って、売電電圧値を固定していた上記従来に比して、電圧変動の許容範囲が同じであっても、多くの売電を可能としうる。その為、複数の発電機が同時に発電する場合であっても、供給電力の品質低下を防止しつつ、売電不能となる状態の発生を抑制することができる。
・上記実施形態では、売電用スマートメータ50からコントロールユニット7までの測定電圧値の送信は、売電用の電力線71を用いて行われるが、他の構成であっても良い。例えば、通常の通信用配線を用いて通信することや、電波によって通信することも可能である。汎用技術を用いることにより、コストダウンがはかれる可能性もある。
