论文摘要
本文介绍了网格连接的氢电解器系统的操作模式和控制架构，用于提供频率和电压支撑。该分析的重点是分层控制方案中的主要和次要回路。在功率转换器内部控制循环下，分析了电压和电流控制模式。在初级级别，描述了提供电压和频率支持的下垂和相反的下垂控制策略。讨论了主要控制与次级，第三级储备之间的协调。案例研究和实时模拟结果是使用台风HIL提供理论研究的。
This paper presents the operation modes and control architecture of the grid-connected hydrogen electrolyzer systems for the provision of frequency and voltage supports. The analysis is focused on the primary and secondary loops in the hierarchical control scheme. At the power converter inner control loop, the voltage- and current-control modes are analyzed. At the primary level, the droop and opposite droop control strategies to provide voltage and frequency support are described. Coordination between primary control and secondary, tertiary reserves is discussed. The case studies and real-time simulation results are provided using Typhoon HIL to back the theoretical investigation.
