Abstract

To evaluate the reliability of islanded microgrid and analyze the impact of energy storage devices on system reliability, a reliability evaluation scheme of islanded microgrid based on sequential Monte Carlo simulation method was proposed. Firstly, the output model of key equipment such as distributed power supply is built by taking the island type wind turbine/diesel generator/energy storage hybrid microgrid system as the research object. Secondly, the reliability evaluation index system, different energy storage operation strategies and load reduction strategies were formulated. On this basis, the reliability evaluation algorithm of islanded wind turbine/diesel generator/energy storage microgrid based on sequential Monte Carlo simulation method was proposed. Finally, through the simulation of the improved RBTS Bus 6 F4 islanding system, the influence of the operation strategy, storage capacity and capacity configuration of the energy storage device on the reliability level of the system was quantitatively analyzed. The results show that reasonable energy storage strategy, appropriate increase of energy storage capacity and appropriate storage system configuration scheme can improve the system reliability.
