本章介绍了电力系统稳定性和控制的一般方面。电力系统控制试图将系统从非正常操作状态返回到正常操作状态。本章强调了角度、电压和频率稳定性以及现有控制的基本概念和定义。节点电压角、节点电压幅值和网络频率是电力系统运行和控制的三个重要量。本章讨论了功角和电压稳定性，可分为小扰动稳定性和大扰动稳定性。本章介绍了各种电力系统控制的时间尺度和特点。监控和数据采集（SCADA）与安全控制、自动发电控制（AGC）和负荷管理一起是现代（EMS）应用层的主要单元。本章还提出了一些挑战和新的研究方向。
This chapter provides an introduction on the general aspects of power system stability and control. Power system controls attempt to return the system from an off-normal operating state to a normal operating state. Fundamental concepts and definitions of angle, voltage and frequency stability, and existing controls are emphasized in the chapter. Angles of nodal voltages, nodal voltage magnitudes, and network frequency are three important quantities for power system operation and control. The chapter discusses angle and voltage stability, which can be divided into small- and large-disturbance stability. The timescales and characteristics of various power system controls are described in the chapter. The supervisory control and data acquisition (SCADA) together with security control, automatic generation control (AGC), and load management are the major units in the application layer of a modern (EMS). The chapter also presents some challenges and new research directions.
