Damping of Low Frequency Oscillation in Power System using QFT FESS controller
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 4
Abstract
In this paper, a robust flywheel energy storage system (FESS) controller using quantitative feedback theory (QFT) is designed to damp low frequency oscillations in spite of uncertainties and various disturbance of power system. To design the QFT FESS controller, the target performance specifications of the closed loop system and system uncertainties are converted to QFT bounds. Through the iterative loop shaping procedure, the FESS controller is designed to satisfy all QFT bounds at all frequencies. To verify control performance of the QFT FESS controller, nonlinear dynamic simulations are performed under various disturbance. The control characteristics with QFT FESS controller have been compared with that of the conventional power system stabilizer (PSS). The simulation results show that the QFT FESS controller provided better dynamic responses in comparison with the conventional PSS controller.
