并网型直流耦合制氢系统(grid-connected DC-coupled hydrogen production system,GDHPS)参与电网调节是能源转型战略下的热门趋势,其需在尽可能为电网提供频率支撑的同时确保电解槽间合理功率分配,而现有文献对该问题研究较少。为此,...并网型直流耦合制氢系统(grid-connected DC-coupled hydrogen production system,GDHPS)参与电网调节是能源转型战略下的热门趋势,其需在尽可能为电网提供频率支撑的同时确保电解槽间合理功率分配,而现有文献对该问题研究较少。为此,该文针对碱液电解槽(alkaline water electrolyzer,AWE),提出一种新型的GDHPS参与频率支撑的控制策略,该策略包含3点改进:一是提出自适应虚拟热敏电阻控制策略,通过控制系统定期更新AWE模型并结合其温度实时计算下垂系数;二是设计频率响应机制以快速响应电网频率变化;三是引入虚拟惯性响应机制提升系统动态性能。所提策略可在宽温度范围内实现AWE间完全分散控制与合理功率共享,同时为电网提供频率支撑,并通过Matlab/Simulink仿真平台及电解制氢实验平台验证有效性。展开更多
