Hybrid energy storage capacity optimization based on VMD-SG and improved Firehawk optimization
Due to the hybrid energy storage system(HESS) in assisting the grid connection of Photovoltaic(PV) energy, the pursuit of smooth effect leads to increased system costs. In this paper, a capacity optimization method considering grid-connected constraints and dynamic balance of energy storage economy is proposed. Firstly, by combining variational mode decomposition(VMD) and Savitzky-Golay filtering method(SG), the photovoltaic power signal is decomposed and reconstructed to minimize energy storage usage while meeting grid connection standards. The reconstructed compensation power is used as the data input for cost analysis. Secondly, considering the energy storage SOC and power constraints, an economic capacity cost model is constructed. Then, chaotic mapping and variable spiral search strategy are introduced to improve the Firehawk optimization algorithm(IFHO), and the optimized capacity allocation scheme is obtained by solving the capacity allocation model. Finally, by analyzing the power data of a photovoltaic energy storage demonstration project in typical days of four seasons in Hebei Province, it is verified that the strategy is effective and economic.
