| Abstract: | The photovoltaic grid-connected generation was greatly influenced by the environment and its utilization rate was low.To solve these problems,two control schemes of PV grid-connected inverter based on ip-iq current detection method of instaneous reactive power theory were presented,and flexible combination of grid-connected generation,dynamic reactive power compensation and active power filter could be achieved.The two control schemes could achieve renewable energy generation,and improve electrical energyqu... |
