The menace of losing stability following a disturbance is one of the results of such a stressed system. Shunt Flexible AC Transmission System (FACTS) namely static synchronous compensator (STATCOM) can play important role to enhance power system stability. To more reduction of power system oscillations, a supplementary damping controller is very essential for STATCOM. A maiden attempt has been made to implement Proportional-Double Derivative (PDD) structure as a supplementary damping controller for STATCOM. To demonstrate robustness of proposed damping controller, it has been compared with Proportional-Integral (PI), Lead-Lag (LL) and Proportional-Integral-Derivative (PID) controllers. Also, dynamic performance of these controllers is evaluated under three different conditions of disturbance in Single-Machine Infinite-Bus (SMIB) power system. The Real Coded Genetic Algorithm (RCGA) optimization technique due to have high sufficiency to solve the very non-linear objective is applied for solution of the optimization problem. The obtained results of the power system stability improvement in SMIB power system reveal the robustness of STATCOM-based PDD damping controller.

W artykule przedstawiono implementację regulatora proporcjonalno-podwójnie-różniczkującego (PDD), do tłumienia oscylacji w kompensatorze STATCOM. Dokonano porównania działania proponowanego regulatora z klasycznymi strukturami jak: PI, LL, PID. Przeprowadzono badania w trzech różnych stanach dynamicznych. Do optymalizacji regulatora wykorzystano algorytm genetyczny RCGA. Wyniki badań potwierdziły, zwiększoną stabilność systemu, a co za tym idzie niezawodność i skuteczność działania regulatora.
