Stable Zones of Fractional Based Controller for Two-Area System Having Communication Delay

Abstract

In this work, an attempt has been made to estimate stable and unstable zones of fractional load frequency controllers for two-area systems. The communication delay is also included in the system. A simple and graphical method is implemented to determine the locus of controller parameters. The controlled system is tested in the MATLAB environment by taking the controller parameters from different zones. The stable and unstable zones of fractional controllers are compared. These MATLAB responses indicate the flexibility of the fractional controller.
