Abstract

This work focuses on a unique approach for an on-line adaptive tuning of Support Vector Machine (SVM) controller to regulate power system frequency whenever load perturbation occurs. A multi-area power system integrating with Hybrid Wind-Diesel system is considered for the present analysis. The proposed SVM controller is trained by input-output dataset of Proportional-Integral-Derivative (PID)-Load Frequency Controller. Primarily, the SVM controller is trained and analyzed with a three-area, nine-machine power system by neglecting system non-linearities. Further, to account for real-time conditions of the power system, all non-linearities and system uncertainties including variable wind input power are considered for the simulation to test the efficacy of the designed controller. The results show the robustness of the designed SVM controller over conventional PID controller. SVM based Load Frequency Controller ensures the zero steady state error for deviations in the frequency and maintaining minimum over/undershoots, the settling time of the frequency and deviation in the tie-line power under all operating conditions.
