Single Area & Two Area Multimachine Load Frequency Control Strategy

Abstract

Using a typical Proportional Integral (PI) controller, the frequency of a single area and two area system was investigated for frequency variation due to load variation in this study. At the same time, the power of two area system tie lines has been regulated. To achieve zero steady state error in tie line power flow, a proportional integral controller is fitted. When compared to a conventional Proportional-Integral-Derivative (PID) controller, the proposed Artificial Neural Network (ANN) controller gave better response for a change in load for single area Load frequency control.
