Abstract

The CHP microgrid with photovoltaic, hydrogen fuel cell, electrolyzer, hydrogen storage is taken as the research object. First of all, the optimization target of minimum annual value of initial investment cost and annual operating cost is established. Secondly, the evaluation index of heat load satisfaction rate of cogeneration microgrid is proposed. Finally, the integrated control strategy of microgrid is designed according to the basic constraints of system operation. Taking the historical source load data to obtain taken as reference, a mathematical model satisfying engineering application is established. PSO algorithm is used to solve the problem and the basic scheme of hydrogen storage island microgrid CHP system was obtained. This paper demonstrates the feasibility of hydrogen energy storage replacing battery energy storage from application level, and the capacity optimization configuration of microgrid system is carried out,which can meet the demand of residents power supply and improve the operation economy of the system. It is expected to have a good application prospect.
