提出了一种基于记忆的事件触发H8负荷频率控制方法。为了克服带宽限制，首先提出了一种基于记忆的事件触发方案（METS），以减少发送的数据包的数量。与现有的无记忆事件触发方案相比，METS具有利用最新发布的一系列信号的优点。针对开放网络引起的随机欺骗攻击，建立了网络化电力系统模型，将METS和随机欺骗攻击耦合在一个统一的框架中。然后，一个充分的稳定性准则推导出的记忆H无穷LFC控制器的增益和事件触发参数同时获得。与现有的无记忆LFC相比，由于充分利用了最新发布的动态信息，控制性能得到了很大的提高。最后通过一个算例说明了该方法的有效性。
This article proposes a memory-based eventtriggering H8 load frequency control (LFC) method for power systems through a bandwidth-constrained open network. To overcome the bandwidth constraint, a memory-based event-triggered scheme (METS) is first proposed to reduce the number of transmitted packets. Compared with the existing memoryless event-triggered schemes, the proposed METS has the advantage to utilize series of the latest released signals. To deal with the random deception attacks induced by open networks, a networked power system model is well established, which couples the effects of METS and random deception attacks in a unified framework. Then, a sufficient stabilization criterion is derived to obtain the memory H infinity LFC controller gains and event-triggered parameters simultaneously. Compared with existing memoryless LFC, the control performance is greatly improved since the latest released dynamic information is well utilized. Finally, an illustrative example is used to show the effectiveness of the proposed method.
