Capacity Allocation of Hydrogen Production and Fuel Cells in Wind Farm Based on Stochastic Prediction Error

Abstract

Hydrogen production system is special energy storage device. Hydrogen production using wind power and electricity generation using hydrogen fuel cells can reduce wind power grid-connected power fluctuation. The optimal capacity allocation is determined based on the hydrogen production and fuel cells energy conversion efficiency. With the target of hydrogen throughput and stabilizing power fluctuation effect, the optimal internal configuration of electrolyzers and fuel cells is determined by comparing the different parameters of them. In the case studies, without the aid of other sources of energy, the system can achieve the goal of reducing wind power fluctuation by the optimal capacity allocation and the internal configuration, which verifies the accuracy and effectiveness of the method in this paper.
