Abstract
Description
本実施形態に係るハイブリッド式電源システム1などの太陽光発電システム(分散型電源システム)等においては、該システム設置後、電源システムのバックアップ機能を充実させる為、ハイブリッド式電源システムにおける電池容量の増大を希望することが予想される。この場合、既存のハイブリッド式電源システムに対して、蓄電池を増設させる対策が考えられる。しかしながら、蓄電池ユニットを増設させると、電池容量や使用状態(蓄電池の健全性(劣化状態)を示すSOH(State of Health)や蓄電池の充電率を示すSOC(States Of Charge))等が異なる蓄電池の性能(スペック)を十分に発揮させるためには、1個の双方向DC/DCコンバータによってすべての蓄電池を制御することは不可能である。これに対して、本実施形態に係るハイブリッド式電源システム1では、各々の蓄電池に対して設けられた双方向DC/DCコンバータにより個別に制御することができるので、各蓄電池の電池容量や使用状態(蓄電池33のSOHやSOC)に応じたスイッチング制御をそれぞれ行うことが可能となるので、各々の蓄電池の性能(スペック)を十分に発揮させることが可能となる。
