摘要

Voltage stability is a growing concern for the successful planning and operation of modern power systems.nThe prediction of voltage collapse point of the multibus power network through its two-bus equivalentnmodel is a hot topic of the research in the field of power system operation and control. This article presentsna method to assess the voltage stability status of a power system incorporating the static var compensatorn(SVC) using a unique two-bus p-network equivalent model obtained with the optimal power flow solutionnof the actual system at different operating conditions. The novelty of the proposed methodology is that itnconsiders the series and shunt parts of transmission losses lumped separately in equivalent series and shuntnform to evaluate the p-network equivalent two-bus model. SVC firing angle model is integrated intonoptimal power flow program to investigate its effect on power system performance in terms of voltagenstability assessed in the equivalent two-bus domain. The simulation results for a practical power systemn(203-bus Indian Eastern Grid) have shown that the proposed methodology is promising to assess voltagenstability of any power system at any operating point in global scenario. Voltage stability marginnaugmentation with the application of SVC at the weakest bus is compared with the system having noncompensation. In the proposed p-network equivalent model, the generators have been modeled morenaccurately considering economic operation. Copyright © 2011 John Wiley & Sons, Ltd.
