Power Oscillation Damping Control using Robust Coordinated Smart Devices
Abstract: The lack of damping
of the electromechanical oscillation modes usually causes severe problems of
low frequency oscillations in interconnected power systems. In the extreme
operating conditions, PSS may fail to damp power oscillation. This paper
presents a robust coordinated design of power system stabilizer (PSS) and
thyristor controlled series capacitor (TCSC) to damp power oscillation in an
interconnected power system. The inverse additive perturbation is applied to
represent unstructured uncertainties in the power system such as variations of
system parameters, system generating and loading conditions. In addition, genetic
algorithm is employed to search a robust tuning to the controller parameters of
both PSS and TCSC simultaneously. Simulation studies have been done in a single
machine infinite bus system to confirm that the performance and robustness of
the proposed controller are superior to that of the conventional controller.
