Abstract

In this paper, we use matlab to build an optical storage microgrid, which consists of photovoltaic power generation, storage battery and load. We do the researches on the traits of the microgrid when it´s in grid-connected mode and off-grid mode. This paper presents different control strategies towards grid-connected condition and off-grid condition. Via the control method, we can achieve the seamless grid-connected operation and off-grid operation between the photovoltaic energy storage microgrid system and the main grid. Further, we use matlab simulation to verify the control strategies´ correctness and effectiveness.
