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