中文摘要

在电力市场放松管制的环境下,传统的频率控制目标与市场驱动策略相结合,以确保竞争性电力市场中电网的可靠高效运行。传统上,电价协议是离线结算的。然而,私营分布式发电公司的兴起和第四次工业革命正推动市场向实时竞价转型,其特点是存在极大的不确定性且网络攻击风险增加。为应对这些挑战,本文提出了一种新颖的模型跟随有限时间鲁棒跟踪控制策略。该方法能有效应对极端时变不确定性、虚假数据注入网络攻击和时滞问题,适用于实时运行。其主要特点包括采用鲁棒控制来减轻不确定性和网络攻击的影响,以及具有带有时滞补偿的有限时间收敛性。在实时竞价市场中的一个典型微电网进行的大量测试表明,即使在遭受虚假数据注入攻击的情况下,该方法也能显著提高频率稳定性和可靠性。在包括调速器死区非线性和时滞等各种条件下,这些改进效果都很明显。与其他方法相比,经Opal RT硬件仿真验证,该方法表现出更强的鲁棒性和更快的收敛速度。这些结果凸显了该方法在确保微电网可靠运行方面的有效性。

English Abstract

In a deregulated environment, traditional frequency control objectives are combined with market-driven strategies to ensure reliable and efficient power grid operations in competitive electricity markets. Traditionally, price agreements are settled offline. However, the rise of private distributed generation companies and the fourth industrial revolution are transitioning the market to real-time bidding, characterized by extreme uncertainty and increased cyberattack risks. To address these challenges, this paper proposes a novel model-following finite-time robust tracking control strategy. The proposed method effectively handles extreme time-varying uncertainty, false data injection cyber-attacks, and delays, making it practical for real-time operations. Key features include robust control to mitigate uncertainties and cyberattacks and finite-time convergence with time delay compensation. Extensive testing on a typical microgrid within a real-time bidding market, even under false data injection attacks, demonstrates significant improvements in frequency stability and reliability. These improvements are evident under various conditions, including governor dead-band nonlinearity and time delays. Compared to alternative methods, the proposed method demonstrates superior robustness and faster convergence, validated by Opal RT hardware simulations. These results highlight the effectiveness of the proposed method in ensuring reliable operation of the microgrid.
