Battery energy storage research of photovoltaic power generation system in micro-grid

At present, micro grid has gradually become the trend of distributed energy applications. View of battery energy storage of PV generation system in micro grid; research the battery energy storage system discharge characteristics and the realization of simulation. Simulation models are designed based on PSCAD / EMTDC platform, corresponding control strategies. Set up the equivalent model and design the control strategy of charge and discharge of battery. This paper put forward fine-tuning control strategy on the battery about Charging current and time, and simulate the model simulation. Results show that the effectiveness of control strategies designs is effective.
