Role of Voltage Stability and Frequency in Power System Operation & Control

Understanding the Interplay of Voltage Stability and Frequency in Power System Operation & Control

Abstract

The basic operating requirement of a power system is that total generation must always be balanced to prevailing total consumption or load and maintaining acceptable levels of voltage and frequency. This paper presents role of voltage stability and power frequency in power system operation & control. It covers voltage collapse phenomena, prevention of voltage collapse, detection of vulnerable systems’ state and load frequency control. Finally conclusions are drawn.
