本文讨论了参与互联的电力系统实体的负荷频率控制（LFC）的分析和设计问题。无论实体是纵向一体化的公用事业、独立的系统运营商还是完全放松管制的市场中的虚拟控制区，基本的实际控制机制都是相同的。本文的目标是双重的：检查已知的启发式设计准则的基本原理，并提出一个有序的控制综合方法。由于电力系统元件及其相互连接的动态模型中存在很大的不确定性，本文提出了一种物理激励的无源性目标作为实现有效闭环控制的手段。定量反馈理论为建议的设计和分析方法提供了方便的图形工具。一个两系统互联的仿真模型被用作一个例子。
This paper addresses the analysis and design issues in load frequency control (LFC) for a power system entity that participates in interconnection. The basic physical control mechanisms are the same whether the entity is a vertically integrated utility, an independent system operator or a virtual control area in a fully de-regulated market. Goals of this paper are twofold: to examine a rationale for known heuristic design guidelines; and to suggest an orderly methodology for control synthesis. Motivated by the large uncertainty in dynamic models of power system components and their interconnections, this paper proposes a physically motivated passivity objective as a means to achieve effective closed-loop control. Quantitative feedback theory provides convenient graphical tools for suggested design and analysis methods. A simulation model of a two-system interconnection is used as an illustration.
