Abstract

The main objectives of this paper are to simultaneously improve power system damping and to maintain voltage at the static var compensator (SVC) location bus simultaneously. A new controller for SVC with closed-form analytic solution nonlinear optimal predictive control (NOPC) law was presented. The controller does not require online optimization and the huge calculation burden can be avoided, so that the demand of real-time control can be satisfied. In addition, there are only two design parameters, which are the predictive period and control order; so it is easy to implement and test in practical use. Simulation results have shown that the controller can not only attenuate power system oscillation effectively but can also maintain voltage at the SVC bus location.
