基于自适应事件触发控制的微电网二次恢复
Secondary Recovery of Microgrid Based on Adaptive Event-Triggered Control
摘要: 针对微电网一次控制引起的电压和频率下降问题，本文提出了一种基于事件触发控制(ETC)和模型参考自适应控制的(MRAC)分布式控制策略，该策略能够在存在噪声干扰和工况改变时实现微电网系统中电压和频率的协同精确恢复。首先通过反馈线性化和状态观测器对微电网的大信号模型进行改进，在此基础上，提出了基于事件触发的模型参考自适应控制律，并通过理论证明了所提方法的稳定性以及不存在芝诺行为。最后，通过仿真实验验证了所提方法的有效性，能更好地应对现实生活中的应用场景。
Abstract: In response to the voltage and frequency drop issues caused by primary control in microgrids, this paper proposes a distributed control strategy based on Event-Triggered Control (ETC) and Model Reference Adaptive Control (MRAC). This strategy can achieve precise recovery of microgrid voltage and frequency in the presence of noise interference and changes in operating conditions. Firstly, the large-signal model of the microgrid is improved through feedback linearization and state observer design. Based on this, an event-triggered model reference adaptive control law is proposed, and the stability of the proposed method as well as the exclusion of Zeno behavior are theoretically proven. Finally, the effectiveness of the proposed method is verified through simulation experiments, and it can better cope with real-life application scenarios.
