Capacity configuration optimization of an integrated energy system coupled with hydrogen storage for a park

In this paper, the capacity configuration optimization of the integrated energy system coupled with hydrogen energy storage are studied in order to provide theoretical guidance for its engineering application. A comprehensive evaluation index was used as the optimization objective and the maximum rectangle method and particle swarm optimization algorithm were used to optimize the system capacity configuration. A park in Xi 'an was taken as the research object, and to obtain its hourly cooling, heating and electric load data of 8760 h in a year were simulated by DeST software. In order to study the effect of the hydrogen storage on the integrated energy system, four storage schemes were compared. The comprehensive evaluation index of the system coupling electrolytic cell and hydrogen storage tank was best，which was 20.04%. The gas turbine capacity of the system was 7000 kW, and the average daily hydrogen supply was 483 kg.
