This research work illustrates the modeling of a traditional controller called
proportional-integral-derivative controller for the automatic generation control in the
system of a single area. The load-dependent equipment is the governor in the automatic
load frequency control, while the parameters of the generator, i.e., time constant and
the gain, are dependent on load in the automatic voltage regulator system. The values
of the parameters do not remain constant when the load varies. These values have to be
constant to maintain stability in the system as these will relate to the performance of the
ALFC and AVR system. In this research work, the PID controller has been used to
control these systems by automatic generation control. Based on simulation results, it
may be reported that the conventional controller has done a superior job by yielding
better performance index values.
Keywords: Automatic Generation Control, Automatic Load Frequency Control, Automatic Voltage Regulator, Proportional-integral-derivative Controller.
