Simultaneous coordination of power system stabilizers and FACTSdevice stabilizers in a multimachine power system for enhancing dynamicperformance

摘要

By using the concept of induced torque coefficients, a method isndeveloped for the simultaneous coordination of power system stabilizersn(PSSs) and FACTS device stabilizers (FDSs) in order to enhance thendamping of the rotor modes of oscillation in a multimachine system. Thenproposed coordination scheme employs linear programming. However,nbecause eigenanalysis using the QR algorithm is required, it is limitednto systems with less than 600-700 states. A case study is given whichnillustrates the coordination of PSSs and FDSs in a three-area systemnwith 29 stations, 3 SVCs and 400 states
