| Abstract | Modern power systems are very complex and critical to electrical engineering services. The interconnections betweenvarious areas, nonlinear dynamics, and huge inertia of the components, make the problem very complex. Any load deviation inone area will affect the others, too. So, in this paper, a robust control strategy is utilized to offer minimal and non-oscillatoryfrequency swings in response to load deviation. The paper also explores and compares the use of covariance matrix adaptationevolution strategy (CMA-ES) based algorithm for the design of optimal robust controller. The controller has been expressed asthe aggregate function of a multi-objective optimization problem. The results obtained show that the robust controller designedusing CMA-ES offers a satisfactory response when compared to classical and other controllers obtained using time-basedperformance indices. |
