Each controller produce different supplementary signals, the power system stabilizer PSS signal for machine and the power oscillation damping POD signal for UPFC. A two stage lead lag compensator scheme was considered in the PSS structure. A new controller design, linear optimal control LOC associated with modal control scheme MO, is proposed in both PSS and POD design. The multi-objective GA method was used to determine the parameter controllers for both PSS and POD. The controller performances were investigated by using small disturbance to power system. The simulation results show that the presence of UPFC non POD leads to get less stability system. Appropriate PSS parameters have been determined and could enhance dynamic responses performance. Using Bryson method for weighting matrix Q, proposed LOC POD could improve system stability. The simulation results also show that system with PSS and MO POD has the best oscillation damping. The dominant eigenvalues shift and approach their real part threshold. POD controllers could give a better rotor angle response, up to 81.33% and 93.9% reduction in overshoot and settling time respectively. Both PSS and UPFC POD controller simultaneously present a positive interaction. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Lihat Sejarah Pengadaan  Konversi Metadata   Kembali
