Optimal svc setting for voltage stability enhancement using a few biologically inspired optimization techniques

Abstract

Due to huge increase in load modern power system networks are newlinebeing operated under highly stressed conditions As a result power system newlinenetworks find it extremely difficult to meet reactive power requirement and newlinemaintain the bus voltage of power system within acceptable limits Voltage newlineinstability in the system occurs in the form of a progressive decay in voltage newlinemagnitude at some of the buses Voltage instability and the resultant voltage newlinecollapse are the major concerns in the operation of power system This newlineresearch work aims to provide a system that will solve the problems of newlinevoltage instability and voltage collapse newlineReactive power compensating devices other than Flexible AC newlineTransmission System FACTS device give only fixed compensation whereas newlineFACTS device provides variable compensation to improve voltage stability newlineenhance voltage profile reduce power losses and also increase the loadability newlineof the system newline newline
