A Fuzzy Power System Stabilizer for DFIG -based Wind FarmsTo Improve Transient Stability of Power Systems

This paper proposes a new fuzzy power system stabilizer (FPSS) in reactivepower control loop of DFIG-based wind farm for improving power systemtransient stability. The proposed FPSS will be compared with a conventionalpower system stabilizer (CPSS) in the same power control strategy. Thestandard Western System Coordinating Council (WSCC) ۳-machines ۹-busessystem was used to investigate the performance of the proposed FPSS. Thesimulation results verify the effectiveness and robustness of the FPSS forimproving the rotor angle oscillations of the power system's synchronousgenerators. Moreover, the system has more fault critical clearing time (CCT)when the DFIG-based wind farm is equipped with the FPSS.
