Simulation Research On Photovoltaic-storage Distributed Power System In Island Operation

Abstract

The stability of island operation of high power distributed power system is the focus and difficulty of distributed power supply research. We use the simulation software PSCAD/EMTDC to establish the model of the power supply system in this paper. The master-slave control method was adopted to simulate the island operating condition of the distributed power supply system. Through the simulation of ground fault condition of each circuit, the influence of ground fault condition on the island operation condition was verified. The simulation results show that the distributed power system with master-slave control can operate normally and stably under steady and ground fault conditions.
