A Dispatch Strategy for Large-scale Wind/Photovoltaic Power Accommodation Based on Multi-Generator System

A dispatch strategy for multi-generator system is proposed in order to solve the problems of large-scale wind/photovoltaic power accommodation and improve the stability of its grid connection. Firstly the output characteristics of various power source in the association system are analysed. Secondly the wind/photovoltaic power is filtered in terms of frequency for getting different multi-frequency components. Thirdly the power outputs of other kinds of power stations are scheduled. Lastly the outputs of multi-generator system and its generators are optimized by a presented fast particle swarm optimization. The simulation results verify that the devised strategy is not only quite capable of settling large-scale wind/photovoltaic power accommodation problem but also specialized in solving the power fluctuation problems. The results also verify that the power output of multi-generator system is stable.
