Dynamic analysis of variable structure based sliding mode intelligent load frequency control of interconnected nonlinear conventional and renewable power system

In this paper dynamic analysis of variable structure based sliding mode intelligent load frequency control of interconnected nonlinear conventional and renewable power system has been carried out using advanced fuzzy logic controller. A new model using variable structure concept of sliding mode fuzzy logic controller has been proposed. The model is simple and gives better dynamics compare to conventional models. The proposed fuzzy logic controller maintains the dynamics of stability and proves its superiority compared to other conventional fuzzy models. Simulation results show that the settling time, percent of peak overshoot, frequency deviations of proposed model are much better than other conventional fuzzy controller.
