Coordinated Design of a Fuzzy Logic Power System Stabilizer and an SVC-based Stabilizer for Single-Machine Infinite-Bus Power System

In this paper, a new coordinated damping controller for power systems is designed based on a Fuzzy Logic Power System Stabilizer (FLPSS) and an Static VAR Compensator (SVC). The test system considered is a Single-Machine Infinite Bus (SMIB) power system for evaluating the performance of the proposed damping controller under various disturbances and load conditions. Nonlinear time domain simulation is done for the proposed controller and compared with a Conventional Power System Stabilizer (CPSS) and a coordinated damping controller of a PSS and SVC (PSS-SVC). Simulation results show the effectiveness and robustness of the proposed damping controller in improving the dynamic stability of power systems over a wide range of operating conditions and disturbances.
