An adaptive critic design (ACD)-based damping controller is developed for a thyristor-controlled series capacitor (TCSC) installed in a power system with multiple poorly damped interarea modes. The performance of this ACD computational intelligence-based method is compared with two classical techniques, which are observer-based state-feedback (SF) control and linear matrix inequality LMI-H(infinity) robust control. Remote measurements are used as feedback signals to the wide-area damping controller for modulating the compensation of the TCSC. The classical methods use a linearized model of the system whereas the ACD method is purely measurement-based, leading to a nonlinear controller with fixed parameters. A comparative analysis of the controllers' performances is carried out under different disturbance scenarios. The ACD-based design has shown promising performance with very little knowledge of the system compared to classical model-based controllers. This paper also discusses the advantages and disadvantages of ACDs, SF, and LMI-H(infinity).
针对安装在具有多个弱阻尼区域间模式的电力系统中的晶闸管控制串联电容器（TCSC），开发了一种基于自适应评判器设计（ACD）的阻尼控制器。将这种基于ACD计算智能的方法的性能与两种经典技术进行了比较，这两种技术分别是基于观测器的状态反馈（SF）控制和线性矩阵不等式LMI-H(∞)鲁棒控制。远程测量被用作广域阻尼控制器的反馈信号，以调节TCSC的补偿。经典方法使用系统的线性化模型，而ACD方法完全基于测量，从而得到一个具有固定参数的非线性控制器。在不同的干扰场景下对控制器的性能进行了对比分析。与基于经典模型的控制器相比，基于ACD的设计在对系统了解甚少的情况下表现出了良好的性能。本文还讨论了ACD、SF和LMI-H(∞)的优缺点。
