<1.第1の実施の形態>
<2.第2の実施の形態>
<3.変形例>
「第1の実施の形態の構成」
図1に示すように、本技術の第1の実施の形態による電源供給システムは、系統電源1、分散電源2及び蓄電システム3を備えている。系統電源1は電力会社が提供する電源である。分散電源2は自然エネルギー例えば太陽光を利用した発電装置2aとPCS(パワーコンディショナ)2bを有する。
上述した第1の実施の形態の制御回路12の制御によってなされる動作について説明する。最初に図2のフローチャートを参照して放電中に系統異常(電圧低下、周波数異常等)が発生した場合の処理について説明する。
ステップST2:電力メータ13によって系統異常の発生が監視されている。
ステップST3:系統異常の発生が検出されると、無瞬断で制御回路12によってスイッチ6が開(OFF)とされる。
ステップST5:系統異常が継続しているかどうかが判定される。
ステップST6:系統異常が継続していないと判定されると、スイッチ6が閉とされる。そして、処理がステップST1(連系放電)に戻る。但し、スイッチ6を閉とする代わりに制御の停止等の任意の動作を行うようにしてもよい。
ステップST7:ステップST5において系統異常が継続していると判定されると、双方向変換装置10が充放電停止状態となり、双方向変換装置11が自立放電を継続する。
ステップST12:電力メータ13によって系統異常の発生が監視されている。
ステップST13:系統異常の発生が検出されると、無瞬断で制御回路12によってスイッチ6が開(OFF)とされる。
ステップST15:系統異常が継続しているかどうかが判定される。
ステップST16:系統異常が継続していないと判定されると、スイッチ6が閉とされる。そして、処理がステップST11(連系充電)に戻る。但し、スイッチ6を閉とする代わりに制御の停止等の任意の動作を行うようにしてもよい。
ステップST17:ステップST15において系統異常が継続していると判定されると、双方向変換装置10が充放電停止状態を継続し、双方向変換装置11が自立放電を継続する。
ステップST22:電力メータ13によって系統異常の発生が監視されている。
ステップST23:系統異常の発生が検出されると、無瞬断で制御回路12によってスイッチ6が開(OFF)とされる。
ステップST25:系統異常が継続しているかどうかが判定される。
ステップST26:系統異常が継続していないと判定されると、スイッチ6が閉とされる。そして、処理がステップST21(連系充電)に戻る。但し、スイッチ6を閉とする代わりに制御の停止等の任意の動作を行うようにしてもよい。
ステップST27:ステップST15において系統異常が継続していると判定されると、双方向変換装置10が充放電停止状態を継続し、双方向変換装置11が自立放電を継続する。
「第2の実施の形態の構成」
図6を参照して本技術の第2の実施の形態について説明する。第1の実施の形態の構成(図1)と対応する構成要素については同一の参照符号を付すことにする。第2の実施の形態による電源供給システムは、系統電源1、分散電源2及び蓄電システム3を備えている。系統電源1は電力会社が提供する電源である。分散電源2は自然エネルギー例えば太陽光を利用した発電装置2aとPCS(パワーコンディショナ)2bを有する。
上述した第1の実施の形態の動作について図7のフローチャートを参照して説明する。一例として、放電中に系統異常(電圧低下、周波数異常等)が発生した場合の処理について説明する。
ステップST32:電力メータ20によって系統異常の発生が監視されている。
ステップST33:系統異常の発生が検出されると、無瞬断で制御回路12によってスイッチ6が開(OFF)とされる。スイッチ17は閉のままである。
ステップST35:系統異常が継続しているかどうかが判定される。
ステップST36:系統異常が継続していないと判定されると、スイッチ6が閉とされる。そして、処理がステップST31(連系放電)に戻る。但し、スイッチ6を閉とする代わりに制御の停止等の任意の動作を行うようにしてもよい。
ステップST37:ステップST35において系統異常が継続していると判定されると、双方向変換装置10が充放電停止状態となり、双方向変換装置11が自立放電を継続する。
ステップST39:双方向変換装置10及び11が共に自立放電を行う。特定負荷8及び19に電力を供給することができる。この場合、分散電源2及び双方向変換装置10を介して蓄電池9を充電することも可能である。
ステップST40:スイッチ6を閉とする。
ステップST41:系統異常が継続しているかどうかが判定される。ステップST41において系統異常が継続していると判定されると、処理がステップST39に戻る。
ステップST42:系統異常が継続していないと判定されると、スイッチ17が閉とされる。そして、処理がステップST31(連系放電)に戻る。但し、スイッチ17を閉とする代わりに制御の停止等の任意の動作を行うようにしてもよい。
なお、上述した第2の実施の形態においては、双方向変換装置10が電力線18に電力を供給していない場合では、系統異常が発生した時にスイッチ6及びスイッチ17を開として無瞬断で特定負荷8及び10に電力を供給することもできる。
「住宅における蓄電システム」
本技術の電池を用いた蓄電装置を住宅用の蓄電システムに適用した例について、図8を参照して説明する。例えば住宅101用の蓄電システム100においては、火力発電102a、原子力発電102b、水力発電102cなどの集中型電力系統102から電力網109、情報網112、スマートメータ107、パワーハブ108などを介し、電力が蓄電装置103に供給される。これと共に、家庭内の発電装置104などの独立電源から電力が蓄電装置103に供給される。蓄電装置103に供給された電力が蓄電される。蓄電装置103を使用して、住宅101で使用する電力が給電される。住宅101に限らずビルに関しても同様の蓄電システムを使用できる。
以上、本技術の一実施の形態について具体的に説明したが、本技術は、上述の一実施の形態に限定されるものではなく、本技術の技術的思想に基づく各種の変形が可能である。例えば、上述の実施形態において挙げた構成、方法、工程、形状、材料及び数値などはあくまでも例に過ぎず、必要に応じてこれと異なる構成、方法、工程、形状、材料及び数値などを用いてもよい。
