Stability Region in the Parameter Space of PI Controller for a Single-Area Load Frequency Control System With Time Delay

This letter proposes a graphical method to compute the stabilizing values of proportional-integral (PI) controller parameters for a single-area load frequency control (LFC) system with time delay. The method is based on the stability boundary locus. The stability region is displayed in controller pa...

Zusammenfassung:This letter proposes a graphical method to compute the stabilizing values of proportional-integral (PI) controller parameters for a single-area load frequency control (LFC) system with time delay. The method is based on the stability boundary locus. The stability region is displayed in controller parameter space and time-domain simulation studies are carried to verify the accuracy and effectiveness of the proposed method.
