摘要: 高热值、零碳排的氢能可为微电网提供优质的调频资源.然而,电制氢(power tohydrogen,P2H)装置的响应频次、爬坡率等安全性约束对微电网负荷频率控制(load frequency control,LFC)策略设计构成挑战.提出一种基于双边自适应事件触发的微电网LFC设计方案.首先,设计了基于双边自适应事件触发的微电网LFC通信方案,仅当控制性能下降到预设阈值以下才允许调整包括P2H装置在内的调频装置运行功率点,从而有效降低P2H装置的动作频次;其次,考虑P2H装置的爬坡约束问题,将基于事件触发的微电网LFC系统描述为饱和非线性模型;最后,通过构造Lyapunov函数确定事件触发及控制器参数的设计准则.算例结果表明,在P2H装置的参与下可使微电网频率偏差幅度进一步下降6.24%,调整时间可缩短1.55%,从而有效增强微电网的频率稳定性.

Abstract: Hydrogen energy with advantages such as high calorific value and zero-carbon emission can provide high-quality frequency regulation resources for microgrids. However, safety constraints such as response frequency and ramp rate of power-to-hydrogen (P2H) devices pose challenges to load frequency control (LFC) strategy design in microgrids. This paper proposes an adaptive event-triggered LFC design scheme for microgrids. Firstly, a bilateral adaptive event-triggered LFC communication scheme is designed for microgrids. The operating power points of frequency regulation devices including P2H devices can be adjusted only when the control performance is degenerated below the preset level, which effectively reduces the action frequency of P2H devices. Secondly, considering the ramp constraints of P2H devices, the event-triggered LFC system in microgrids is modeled as a saturated nonlinear model. Finally, the design criteria for event-triggering and controller parameters are determined by constructing a Lyapunov function. Simulation results show that P2H device participation can decrease the frequency deviation amplitude of the microgrid by 6.24% and shorten the settling time by 1.55%, thereby effectively enhancing the frequency stability of the microgrid.
