Monte Carlo Simulation Based Reliability Evaluation of Distribution System Containing Microgrids

Abstract

To evaluate the reliability of distribution network containing microgrids such as distributed generations(DGs) and energy storage system,at first the stochastic characteristics of power output of photovoltaic generation and wind power generation are researched,and a reliability model of hybrid generation system consisting of distributed generation and energy storage system is built.On this basis and based on Monte Carlo simulation a reliability evaluation algorithm for distribution network containing microgrids is proposed.Finally,the reliability of modified IEEE DRTS Bus 4 is evaluated by the built model and the proposed algorithm.Evaluation results show that microgrids can effectively improve power supply reliability of distribution system.
