Abstract

This paper presented an extensive analysis of dynamic change of power flow between distributed generators and loads in the situation of low grid voltage. And, a control strategy with energy storage to balance the power flow was proposed. First, the constant power control strategy of the distributed generators such as photovoltaic power generation and wind power generation was realized, and the output power flow of the voltage source converter was also analyzed. Second, with different types of system loads which were constant power load and constant impedance load, the dynamic process characteristics of the distributed generators and the loads were presented when the grid voltage was lower than the normal value. Finally, energy storage equipment was used to balance the power flow, and the control method of the energy storage was also presented. Based on these analyses, the characteristics of distributed generation system are obtained. Simulation investigation results are finally provided to verify the analysis and specification.
