风光储微电网功率控制策略研究

he integration of low rating wind power/photovoltaic with intermittent and random characteristics and energy storage can fully explore the potential of renewable energy power generation.Simultaneously, it can solve the problem of output power fluctuation of the grid-connectedwind/PV/storage hybrid system. Considering the random variation of wind speed, illuminationintensity, in this paper, a power control strategy is proposed. By coordinated controlling between two micro sources and energy storage, the output power of wind/photovoltaic/energy storage hybrid system can be unchanged.Simultaneously, the voltage of Point of Common Coupling (PCC) can be stabilized. In this paper, a wind/photovoltaic/energy storage hybrid Power System is built by MATLAB/Simulink simulation software. The simulation results verify the correctness and effectiveness of the proposed control strategy.
