This article deals with the load frequency control problem of multiarea power systems subject to multiple intermittent denial-of-service (DoS) attacks that can interrupt the data transmission of each area independently. A decentralized event-triggering (ET) scheme under periodic sampling is proposed to reduce the transmission burden. Then, a decentralized ET-based controller is designed by tuning several parameters. Such control scheme can reduce the computational complexity while achieving privacy preserving. Moreover, sufficient conditions are derived for ensuring the input-to-state stability of multiarea power systems and an optimization solution method via particle swarm algorithm is provided. Finally, a three-area power system is employed to verify the effectiveness of the proposed scheme.
本文研究了多区域电力系统在遭受多个间歇性拒绝服务（DoS）攻击时的负荷频率控制问题，这些攻击可独立中断各区域的数据传输。提出了一种周期性采样下的分散式事件触发（ET）方案，以减轻传输负担。然后，通过调整几个参数设计了一种基于分散式ET的控制器。这种控制方案在实现隐私保护的同时，可以降低计算复杂度。此外，还推导了确保多区域电力系统输入到状态稳定性的充分条件，并提供了一种基于粒子群算法的优化求解方法。最后，采用一个三区域电力系统来验证所提方案的有效性。
