✦ Synopsis

Abstract

With communication signal delays, a power system control can actually excite sustained oscillations. This paper proposes a method to analyze the stability of such delayed systems and the like. The stability is estimated using delay margins. The main result is nicely based on a sufficient and necessary condition. Simulation results of the Automatic Generation Control (AGC) system of the real‐world East China Power Grid (ECPG) system are reported to validate the methodology.

Two new asymptotic stability criteria for linear time-invariant systems with multiple delays are established by using a quadratic inequality lemma together with frequency-domain techniques. One criterion is for delay-dependent ␣-stability and another is for delay-independent asymptotic stability. Ea
