Summary:

In this thesis, load frequency control of three different two-area power systems is

realized. Two-area reheat thermal power system, two-area multi-source power system and

non-linear two-area multi-source power system models are established and the behavior of

four different controllers is observed for these models under two types of load changes.

Proportional-integral-derivative (PID), tilt-integral-derivative (TID), tilt-integral-derivative

with derivative filter (TIDF) and tilt-integral-derivative with fractional derivative filter

(TIDFF) are the controllers designed and used in the thesis. Aiming to minimize the time-weighted absolute error (ITAE) metric, which is one of the error-based performance

metrics, the controllers are designed by optimizing with the Equilibrium Optimization

Algorithm. The objective function value, frequency change curves and tie line power

curves obtained after the control of the power system models with the controller are

examined and the settling time, undershoot and overshoot values of these curves under

certain conditions are presented. The results obtained are presented in comparison with the

studies in the literature.

For most of the cases, the fractional calculus-based controllers, i.e. TID, TIDF and

TIDFF, are found to outperform the performance of the classical PID controller.
