Modelling control of a multimachine power system with facts controller

Abstract

newline Flexible Alternating Current Transmission System (FACTS) newlineis a stationary tool that is used to operate the power transmission system. newlineFACTS is a power electronic-based system and other stationary newlineinstrument that allows users to alter one or more AC transmission newlinesystem parameters to improve controllability and power transfer newlinecapabilities. The different kinds of FACTS tools accessible for this newlinepurpose comprises Static Var Compensator (SVC), Thyristor controlled newlineseries Capacitor (TCSC), Static Synchronous series compensator newline(SSSC), Static Synchronous Compensator (STATCOM), Unified Power newlineFlow Controller (UPFC) and Interlink Power Flow Controller (IPFC). newlineUPFC is one of the FACTS tools among them that can manage the newlinepower flow in transmission line by inserting active and reactive voltage newlinecomponent in series with the broadcasting line. newlineTo improve reactive power or dynamic stability, a hybrid newlinestrategy based on optimal location and sizing of HPFC is presented. newlineBecause the generator outage affects power flow restrictions such as newlinepower loss, voltage, real and reactive power flow, the largest power loss newlinebus is chosen as the most advantageous site for fixing the HPFC. The newlineGA algorithm was used to find the best position.The required amount of newlinethe UPFC to recover the starting operating condition is optimised based
