The Utility Analysis of LHSS Combined SMES System Considering Capacity Configuration

Based on common characteristic that liquid hydrogen storage system(LHSS) and superconducting magnetic energy storage(SMES) has similar requirement for refrigeration, This paper analyzes advantages of joint operation of LHSS combined SMES system based on their common characteristics. Consider current situation of renewable energy utilization difficulties in recent years, this paper studies the optimal capacity configuration of LHSS combined SMES hybrid energy storage system to maximum use renewable energy. Based on above scene, a time series based method is proposed to simulate the operation scenario of a high penetration renewable energy system, and a capacity optimization method which objects to maximize the economic benefit of hybrid energy storage system is also proposed in this paper. Also, the effectiveness of the proposed strategy is verified by a simple case.
