Summary: | To perform a proper output suppression control using a conversion circuit 100 for various output suppression events.SOLUTION: A conversion circuit 100 includes an inverter 13. The conversion circuit 100 converts DC power output from a DC power source (a solar cell 2 and a power storage unit 3) via at least inverter 13, and output the power AC power to a load 5 or an electric power system (system 4). A control circuit 101 is configured so as to, when obtaining a piece of information that two or more output suppression events have occurred, control the conversion circuit 100 to output at maximum suppression in two or more suppression amounts according to the content of two or more output suppression events.SELECTED DRAWING: Figure 1
【課題】各種の出力抑制事由の発生に対して、変換回路100において的確な出力抑制制御を行う。【解決手段】変換回路100は、インバータ13を含む。変換回路100は、直流電源(太陽電池2及び蓄電部3)から出力される直流電力を少なくともインバータ13において電力変換して交流電力として負荷5又は電力系統(系統4)に出力する。制御回路101は、2つ以上の出力抑制事由が発生したことを示す情報を得ると、2つ以上の出力抑制事由の内容に応じた2つ以上の抑制量のうち、最大の抑制量にて変換回路100に出力抑制させる。【選択図】図1 |
