摘要：
As the coupling between the power system and the hydrogen system deepens, the AC/DC hybrid microgrid with the elec-tricity-hydrogen system (EHS) has become one of the development directions of energy systems. In this work, the reliability evaluation of islanded AC/DC hybrid microgrid with EHS is carried out. Firstly, an EHS model and a load model are established. Secondly, the reliability index system is defined from the perspective of system-level and equipment-level. Also system power scheduling strategies and shedding loads strategies are put forward. Thirdly, random factors such as component failure and source-grid-load uncertainty are taken into account, and the reliability evaluation method based on the sequential Monte Carlo simulation method is proposed. Finally, the improved RBTS BUS6 F4 feeder system is applied to analyze the system reliability and the influence of total capacity of new energy and capacity of equipment in EHS on system reliability. The results show that the system reliability can be effectively improved with an EHS. The total capacity of new energy has an optimal value, which makes the system reliability the highest. Increasing the capacity of certain equipment in the EHS, the system reliability can be improved but the degree of improvement is restricted by the capacity of the equipment. © 2021, High Voltage Engineering Editorial Department of CEPRI.
