Abstract: This paper demonstrates a modified PID controller that gives enhanced performance in terms of amplitude of first peak, overshoot, and time of settling. The significance of this research work stems from the point that modified PID controller for unit of wind power (WU) with inertial control (C-I), integration of controller of inertial and droop (C-D), and integration of controller of inertial, droop, and pitch angle (C-P) has not been counted in literature so far in totality. In addition, the same controller is not implemented for the TP with WU for C-P with different step load perturbations. The suggested controller is established by cascading of derivative filter with PID controller to restrict the noise sensitivity in PID controller. For validation of the proposed controller, it is employed in different scenario and compared its performance with conventional PID controller. Also, this article compares different frequency regulation techniques of WU separately and gets the best possible combination of controller to offer the boosted performance of the system. The suggested controller has been simulated in MATLAB/SIMULINK ver. 2013 environment. Simulation results show the reductions in frequency deviation and tie line power deviation when TP is subjected to modified PID controller. The major contribution of this work is to advance regulation of frequency and power, which leads to enhanced grid stability.
