Frequency Control Strategy and Test Technology of Photovoltaic Power Plant

摘要

Due to the increase of photovoltaic (PV) generations, the current power system is under extraordinary pressure of the frequency regulation for the frequency adjustment device is reduced. In this paper, in view of the grid-connected PV generations, the frequency control strategy, modification method and testing method are proposed. After quantitative analysis of the frequency regulation performance of the PV generations and compared with synchronous generator primary frequency performance, the simulation results shows that the PV generations could participate in power system frequency control with a good technical performance.
