To mitigate the adverse impacts of the volatility and randomness of wind and photovoltaic resources on the lifespan of electrolyzers
this paper proposes a regional integrated energy system scheme based on collaborative hydrogen production using hybrid electrolyzers. The system leverages the complementary advantages of alkaline electrolyzers and proton exchange membrane electrolyzers to effectively extend the service life of the electrolyzers. A capacity optimal configuration model is established with the objective of minimizing the annual average system cost
and the secretary bird optimization algorithm is employed to determine the optimal configuration of wind turbines
photovoltaics units
gas turbines
batteries
fuel cells
alkaline electrolyzers
proton exchange membrane electrolyzers
hydrogen storage tanks
thermal storage equipment
and gas boilers. The simulation results demonstrate that the proposed system reduces the electrolyzer life degradation cost
effectively extends their service life
and enhances the system's economic efficiency by recovering and utilizing the waste heat generated by fuel cells and electrolyzers.
