Optimal Capacity Planning of a PV-Battery-Hydrogen System for Microgrid in Grid-Connected Mode

To improve the overall economy of the microgrid during the design and planning stage, a microgrid capacity configuration model containing photovoltaic, batteries, and hydrogen storage is proposed in this paper. The model of each equipment unit and the system control method are considered comprehensively. Demand response is utilized for load management, relieving pressure on the generation and storage sides. The configured capacity of each device is obtained by solving the optimization model using an improved particle swarm algorithm. The validity of the model is verified by using case simulations, and the impact of demand response on the allocation results and the influence of the algorithm on the optimization are also analyzed.
