TIDF-II controller for hybrid system with renewable sources

Abstract

With the integration of renewable sources, modern power system is the unpredictable nonlinear system. The incorporation of sustainable power sources causes frequency deviation and power oscillations due to insufficient damping and progressively changing demand conditions. Initially the power system does necessary adaption to make equilibrium point between demand and supply. But it is stiffer to get a satisfactory point by utilizing conventional control techniques. To resolve this issue new control schemes are required. In this paper, tilt integral derivative with filter plus double integral (TIDF-II) control strategy is implemented to alleviate the frequency deviation and other power system stability issues. A newly appeared sine cosine algorithm (SCA) is exploited to optimize the parameters of TIDF-II controller. The functioning of SCA-TIDF-II controller is contrasted with other existing controllers to show its supremacy. Also, time-domain analysis demonstrated to endorse the procured results. Further, to test the sturdiness of SCA-TIDF-II controller, 5% change in step load and random load perturbations are included. Results of both cases show the dominance of SCA-TIDF-II controllers over others.
