氢能在能源转型中占据着越来越重要的地位。传统的氢电耦合直流微电网设计方案中,制氢设备并联嵌入直流微网,并作为一种灵活性负载参与系统调控以平替部分储能的功能。但是碱液电解槽(alkaline water electrolyzer
AWE)具有低压大电流的特点。随着直流微电网电压等级的提升,传统的并联结构一方面增加了电力电子装置的电压转换比的需求,另一方面忽略了碱液电解槽的电热特性。针对以上问题,该文提出了一种基于虚拟热敏电阻的串联型氢电耦合直流微电网稳定控制策略。首先,针对碱液电解槽建立了一套等效电热模型以表征最大电流与温度的关系。在此基础上,提出了一种电堆串联结构的碱液电解制氢模块(series-connectedstacks alkaline water electrolysis module
