Optimal Scheduling of Solar Hydrogen Storage in Jilin Province Based on Hierarchical Analysis Approach

As human demand for energy continues to rise, the problems of resource scarcity and environmental degradation are becoming more and more serious. In order to reduce the impact of stability reduction in renewable energy access microgrid, a thermoelectric-hydrogen coupled microgrid system is proposed. This paper analyzes in detail the structure of the thermoelectric-hydrogen coupled microgrid system and the operation mechanism of each device in the system, and establishes a mathematical model of the microgrid system. Then, by studying the operating characteristics of the thermoelectric-hydrogen coupled microgrid system, the optimal solar energy scheduling based on hierarchical analysis method is formulated. Finally, in order to verify the feasibility of the optimal scheduling method proposed in this paper, a case simulation is carried out to verify it. Taking a microgrid system in Jilin Province as an example, this paper uses the PV generation and load data in the region, and selects three typical days in winter, summer, and transition seasons for analysis to derive the optimization results of the scheduling. The results show that the addition of hydrogen energy storage effectively improves the economy of the system.
