REQUENCY CONTFUZZY TUNED PI CONTROLLER BASED AUTOMATIC LOAD FROL OF MULTI AREA SYSTEM

Abstract

                 Currently as there has been an increase in the interconnected systems as far as power systems are concerned. Load as well as power flow in tie-line are varying dynamically. So there is a need of robust control of system frequency as well as tie-line power flow system. This robust control could be achieved by the help of fuzzy logic controllers in the place of orthodox system using proportional, PI and PID controllers
