A Robust TFPDC Based Power System Stabilizer

چکیده
This paper presents a robust Takagi-Sugeno Fuzzy Parallel Distribution Compensation (TSFPDC) based Power System Stabilizer (PSS) for damping power system low frequency oscillations. The main motivation of using this controller is minimizing the efforts of load disturbances and achieves the desired level of robust performance in the presence of modeling uncertainties. The effectiveness of the proposed method is verified on a NewEngland test system under various load demand and disturbances in comparison with the Strength Pareto Evolutionary Algorithm (SPEA) based designed PSS through nonlinear time domain simulations and system performance indices. The results evaluation show that the proposed control strategy achieves good robust performance for a wide range of system parameters and load changes in the presence of system nonlinearities and is superior to the other stabilizers.

This paper suggests a method for designing PSS to damp multi-machine power system oscillations. The method is based on robust control theory. First, the conventional method for designing robust controller in LMI framework is illustrated. Then, the suggested method is given, in which, a PID output feedback controller is tuned using the LMI approach. Mostly, the classical methods are used t...

متن کاملAlleviating the Small-Signal Oscillations of the SMIB Power System with the TLBO–FPSS and SSSC Robust Controller
Power systems are subjected to small–signal oscillations that can be caused by sudden change in the value of large loads. To avoid the dangers of these oscillations, the Power System Stabilizers (PSSs) are used. When the PSSs can not be effective enough, installation of the Thyristor–based compensators to increase the oscillations damping is a suitable method. In this paper, a Static Synchronou...
