传统的电力系统稳定器(PSS)是通过发电机励磁系统作用的主要局部阻尼器。有研究表明，远程信号可能会增加比本地信号所能达到的更大的衰减。提出了一种基于广域测量的监控级电力系统稳定器。该控制器具有较强的鲁棒性，能够补偿电力系统的非线性动态运行和不确定扰动。基于多智能体系统理论的原理，实现了鲁棒PSS和局部PSS的协调。该理论是分布式人工智能(DAI)中一个活跃的应用分支。以一个29机179节点的电力系统为例，研究了该控制器作为电力系统稳定剂的性能。
Conventional power system stabilizers (PSS) are major local damping controllers acting through generator excitation systems. There are studies that suggest that remote signals could si-crease damping beyond that attainable by local signals. A supervisory level power system stabilizer (SPSS) using wide-area measurements is proposed. The robustness of the proposed controller is capable of compensating for the nonlinear dynamic operation of power systems and uncertain disturbances. The coordination of the robust SPSSs and local PSSs is implemented based on the principles of multiagent system theory. This theory is an active branch of applications in distributed artificial intelligence (DAI). The performance of the robust controller as a power system stability agent is studied using a 29-machine 179-bus power system example.
