Summary:This paper presents a simulative technique to evaluate the reliability of distribution system including distributed generations (DGs) and energy storage system, which compose microgrids with load. The introduction of energy storage system will play an important role on the stable of power supply in microgrids where renewable energy DGs are connected. Stochastic characteristic of photovoltaic and wind power DGs is firstly studied, and then a reliability model for the combined DGs and storage energy system is established. On the base of the above models, a reliability evaluation algorithm for microgrids based on Monte Carlo simulation is proposed. Case studies on the modified IEEE RBTS Bus 4 system containing two microgrids verify the validity of the proposed technique. Results prove that microgrids are capable to improve the power supply reliability for their customers.
