Research on Power Quality Integrated Control Technology for Photovoltaic Poverty Alleviation Rural Grid
Aiming at the operation characteristics of rural distribution network with photovoltaic for poverty alleviation, this paper presents a coordinative control technology of grid connected photovoltaic and energy storage system based on the power control of inverters. The voltage/reactive power control principle of the inverter was analyzed, and the system of photovoltaic and energy storage was established in a low voltage distribution network.Setting the control of the dead zone of the inverter to guarantee the priority of reactive power adjusting, meanwhile, the power supply and energy storage can be controlled coordinately to smooth the output of power.Finally, verified the low voltage distribution network with Opendss software, and the simulation results show that the proposed control strategy can effectively improve the power quality of the rural grid.
