Abstract:
Modern power system networks consist of a number of utilities
interconnected networks together . Power is exchanged between utilities
over tie-line by which they are connected. Automatic generation control
(AGC) plays a very important role in power system. Its main role is to
maintain the system frequency and tie-line flow at their scheduled values
during normal period and also when the system is subjected to small step
load perturbations. In this study, a power system with two areas
connected through tie-line is considered. The objective of AGC, based on
fuzzy PID controller, is to damp transient deviations(frequency and
power)and to provide zero steady-state error of these variables in a very
short time. The simulation is implemented by using
MATLAB/SIMULINK program. To further adding various types of
membership functions and applying for more than two area power
system.
