AUTOMATIC GENERATION CONTROL OF TWO AREA REHEAT THERMAL SYSTEM WITH GENERATION RATE CONSTRAINTS USING FUZZY LOGIC

Abstract

In this paper automatic generation control (AGC) of two area power system has been studied with and without generation rate constraints (GRC). When GRC is introduced in the system then actual frequency deviation is obtained which is more than without GRC consideration case. During load disturbance system frequency goes down which comes back around nominal system frequency on increasing the generation of the system. Overshoot and settling time of frequency deviation increases when GRC is taken into account. Analysis is based on MATLAB/SIMULINK 2010a.
