摘要:

氢能具有清洁、高能量密度的特点,是可再生能源大规模消纳和能源清洁化利用的重要技术路径。针对光伏耦合电解制氢系统的经济性问题,提出一种基于不同电价的系统协同运行功率优化分配策略。建立光伏和碱性电解槽的数学模型,并分析电解槽产氢速率与功耗之间的非线性动态关系。在此基础上,以系统总收益最大化为目标,所提策略利用电价差异引导能量在并网售电与电解制氢之间进行动态分配。结果表明,所提策略能根据电价和光伏出力情况,有效优化功率分配,从而在不同时段均实现收益最大化,为光伏耦合制氢系统经济运行提供了技术支撑。

Abstract:

Hydrogen energy, characterized by its clean nature and high energy density, is a key technical pathway for the large-scale integration of renewable energy and clean energy utilization.To address the economic challenges of photovoltaic(PV)-coupled electrolytic hydrogen production systems, a coordinated operational strategy for optimal power allocation based on varying electricity prices is proposed.Mathematical models for the PV system and the alkaline electrolyzer are developed, and the nonlinear dynamic relationship between the electrolyzer's hydrogen production rate and its power consumption is analyzed.On this basis, with the objective of maximizing total system revenue, the proposed strategy utilizes electricity price differences to dynamically allocate energy between grid sales and electrolytic hydrogen production.The results show that the strategy effectively optimizes power allocation according to electricity prices and PV power output, thereby achieving revenue maximization in different time periods.This work provides technical support for the economic operation of PV-coupled hydrogen production systems.

Key words: photovoltaics, hydrogen production, power supply for hydrogen production, revenue optimization
