چکیده

A modified particle swarm optimization is proposed and used for coordinated designing of the power system stabilizer and unified power flow controller as a damping controller in the multi-machine power system. For evaluation of the effectiveness and robustness of the proposed controllers, their performances have been tested on a weakly connected power system subjected to different disturbances. The results of these studies show that the proposed coordinated controllers have an excellent capability in damping power system inter-area oscillations and enhance greatly the dynamic stability of the power system. Streszczenie. W artykule opisano metodę projektowania struktury sterowania układem elektrycznym wielomaszynowym, gwarantującej stabilność pracy i jednostkowy współczynnik mocy. W metodzie wykorzystano zmodyfikowaną optymalizację rojem cząstek. Analizy skuteczności i odporności polegała na poddaniu zakłóceniom systemu przy połączeniu słabym. Wyniki badań potwierdzają skuteczność proponowanego rozwiązania. (Projektowanie struktury UPFC i PSS dla zwiększenia stabilności mocy w systemie).
