The stochastic output characteristic of wind power generating units in wind farm is analyzed. Taking the operation strategy, working condition and charging/discharging constraints of energy storage system into account and through all sequential simulation, the operating characteristics and reliability of microgrid operated in isolated island mode are emphatically analyzed. Based on the idea of load partitioning and synthetically considering the two factors of the importance and the position of load, the load shedding strategy under isolated island mode of microgrid is researched. Finally, based on the features of island operation mode two novel reliability indices, namely the first average continuous working period of microgrid operated in isolated island mode and the rate of operational stability, are proposed, and using the two novel reliability indices the reliability evaluation of modified RBTS Bus6 is performed, and simulation results show that the proposed model and reliability evaluation algorithm are effective.
