| Summary: | This paper presents an application of Grey Wolf Optimizer (GWO) technique to estimate the
parameters of the Proportional Integral Controller (PI) for Automatic Generation Control of two
area power system. In this work two thermal units with non reheat turbines are considered. The
detailed eigenvalue analysis is carried out for exhibiting the philosophy of damping requirement in
the complex networks. The parameters namely proportional integral gain, speed regulation,
frequency sensitivity coefficient are considered as the modifiable parameters. These parameters
are estimated through optimization process with the aim to minimize the Area Control Error
(ACE). The comparison between two objective functions namely Integral Square Error (ISE) and
Integral Time Absolute Error (ITAE) is presented. Sensitivity analysis advocates the
effectiveness of the proposed approach. To draw a fair comparison between the proposed method
and the conventional methods (GSA, PSO and GA) convergence characteristics of the
optimization techniques are compared and presented. It is observed that the proposed design
satisfactorily handle different contingencies and operating conditions |
