Coordinated Control Study of Hybrid Electrolytic Hydrogen Production Based on Photovoltaic DC Microgrids

鉴于光伏发电功率波动频繁且波动幅度大,电解制氢系统不能快速响应。本文提出一种基于光伏直流微电网的多方式电解制氢方案,对分布式光伏发电微网模式下电氢耦合系统控制策略进行研究。本文所提出的构想有利于减少动态弃光,改善运行的平稳性,完成电氢耦合的整体源网荷的实时功率平衡,提高电氢耦合系统整体能效水平和经济性。

PV power fluctuations are frequent and large,and the electrolytic hydrogen production system cannot respond quickly.This paper proposes a multi-modal electrolytic hydrogen production scheme based on a PV DC microgrid,and investigates the control strategy of the electro-hy-drogen coupled system in the microgrid mode of distributed PV power generation.The concept proposed in this paper is conducive to reducing dy-namic light abandonment,improving the smoothness of operation,accomplishing the real-time power balance of the overall source-grid-load of the electro-hydrogen coupling,and improving the overall energy efficiency level and economy of the electro-hydrogen coupling system.
