Power allocation strategy for electrolytic cell cluster system for high proportion photovoltaic consumption

Abstract

Abstract Limited by the capacity of a single electrolytic cell, the large-scale hydrogen production system must be operated by a combination of multiple electrolytic cells to form an electrolytic cell cluster. Meanwhile, photovoltaic power generation has real-time changes of uncertainty. Allocating the operating power safely, efficiently, and reasonably to each electrolytic cell in the cluster is a crucial issue for large-scale hydrogen production systems. Therefore, this paper proposes a power allocation strategy for the electrolytic cell cluster system. Firstly, the operation characteristics of a single electrolytic cell and cluster are analyzed. Then, considering constraints such as power balance, electrolytic cell power limitations, and grid restrictions, a power allocation model for electrolytic cell clusters is established to maximize photovoltaic consumption. Based on this, a power coordination allocation strategy for the single electrolytic cell is provided. Finally, the effectiveness of the proposed strategy is verified through an example analysis.
