摘　　要：针对光伏制氢系统受环境影响导致光伏出力波动性强、制氢效果不理想等问题,在光储耦合制氢系统模型基础之上,以提升光伏发电质量、平滑制氢以及增强系统稳定性为目的,采用了一种基于稳压控制的光储一体化耦合制氢系统控制策略。该控制策略包括光伏系统的最大功率点跟踪(MPPT)控制,电化学储能系统自适应协调控制等,可在实现最大光资源利用的同时,保证母线电压稳定以及制氢平滑性,通过仿真验证了该控制策略的有效性。Photovoltaic(PV) hydrogen production systems are affected by the environment,resulting in strong fluctuation of photovoltaic output and unsatisfactory hydrogen production effect.To solve these problems,based on the model of the photovoltaic storage coupled hydrogen production system,a control strategy for the photovoltaic storage integrated coupled hydrogen production system based on voltage stabilisation control is adopted for the purpose of improving the quality of photovoltaic power generation,smoothing hydrogen production and enhancing system stability.The control strategy includes the maximum power point tracking(MPPT) control of the PV system and the adaptive coordinated control of the electrochemical energy storage system,which can guarantee stable bus voltage and smooth hydrogen production while realizing the maximum use of solar resource.At last,the effectiveness of this control strategy is verified by simulation.
