论文摘要
自动发电控制（AGC）是现代互连电源系统中最重要的协调控制系统之一。尽管经过大量研究，但文献中仍未使用AGC的互连动态稳定性和性能分析。本文为一类多区域互连的非线性功率系统提供了这样的分析，提供了非线性稳定性证明，并从非相互作用调整，响应速度和对干扰的敏感性的角度检查了动态性能。关键见解是，动态稳定性和性能可以通过简化的动态模型严格捕获，这仅取决于AGC控制器参数和区域频率特性常数。我们的分析结果阐明了有关动态稳定性和性能的频率偏差常数调整的一些历史争议，并通过详细测试系统上的模拟来验证。
Automatic generation control (AGC) is one of the most important coordinated control systems present in modern interconnected power systems. Despite being heavily studied, no interconnected dynamic stability and performance analysis of AGC is available in the literature. This paper presents such an analysis for a class of multi-area interconnected nonlinear power systems, providing a nonlinear stability proof and examining dynamic performance from the perspectives of non-interactive tuning, response speed, and sensitivity to disturbances. The key insight is that dynamic stability and performance can be rigorously captured by a reduced dynamic model, which depends only on the AGC controller parameters and on the area frequency characteristic constants. Our analytical results clarify some of the historical controversy concerning the tuning of frequency bias constants in AGC for dynamic stability and performance, and are validated by simulations on a detailed test system.
