Automatic Rescheduling of Generator for Rotor Speed Regulation by KRASOVSKII’s Theorem

Emergency control of the power system is performed via generator rescheduling or load shedding depending upon availability generation and demand. This paper presents a method based on Krasovskii’s theorem for enhancing rotor speed regulation during multiple contingency conditions. The governor in automatic (AGC) voltage regulator (AVR) are indispensable components mechanism deploying any scheme. Contingencies may lead security state towards preventive, emergency, restorative state. Generally, there violation equality constraints active reactive corrective However, this paper, considers significant imbalance with capacity always greater than load. For angle stability, delivery by met demands, whilst turbine together balance it changing set point inlet. investigates stability triggering new generator. strategy proposed encompasses broad domain using theorem, which an extensive form Lyapunov nonlinear multivariable autonomous system. scheme deployed IEEE-10 machine 39-bus validation feasibility detection.
