Considering the severity of modal aliasing in frequency division within offshore wind farms
a method for configuring hybrid energy storage capacity is proposed
based on an improved artificial protozoa optimizer (APO) integrated with successive variational mode decomposition (SVMD). In this method
SVMD is adopted to decompose the discrepancy between raw wind power and grid-connected power
with the compensatory power for the electro-hydrogen hybrid energy storage system being determined through a combination of fast Fourier transform and maximizing spectral entropy difference. The hybrid system consists of a super-capacitor system and a hydrogen storage system encompassing a desalination unit
electrolyzer
hydrogen storage tank
and fuel cell. With the dual objectives of minimizing the overall cost of the energy storage system and maximizing the stabilization of offshore wind power fluctuations
a capacity allocation optimization model is formulated and solved using the refined APO algorithm. Simulation analysis validates the efficacy and economic viability of the proposed method in stabilizing these fluctuations.
