Research and Development of New Energy Microgrid Charging Simulation Platform

Abstract

With the rapid growth of electric vehicles, the grid load continues to increase, which is bound to impact the operating efficiency of the grid. For the promotion and popularization of electric vehicles, the establishment of new energy microgrids represented by photovoltaic microgrids is a better solution for electric vehicle charging. This paper analyzes the influencing factors of photovoltaic charging through a large number of experimental data, and develops a micro-grid charging simulation system. The established micro-grid charging simulation system can simulate the irregular DC voltage waveforms when different energy sources are converted into electric energy. It lays a foundation for the measurement performance of electric vehicle charging piles in the microgrid environment under the real state of simulation testing, ensures the stable performance of charging piles under various extreme voltage conditions, and fills the technical gap of simulation testing in domestic microgrid systems.
