In this study, Fuzzy-logic based Proportional-Integral-Derivative controller with filter (F - PID- N) is recommended in the Load Frequency Control loop to regulate the frequency of a two-area, multi-source power-system. Since, now-a-days the load demand increases exponentially, renewable energy sources are chosen as the best alternatives to meet the desired load demand. Hence here solar unit is added in both the areas with the conventional hydro-thermal system and the whole system is considered for the study of dynamic stability. The above controller is proved to be superior by comparing it's result with that of PID controller. The controller gains are obtained through the efficient Wild-Goat-Algorithm (WGA). For the conduction of the experiment, 1 % load variation is inserted in the area-1 of the system taken for the study. Further Capacitive Energy Storage device is used as the energy storage system (ESS) to reduce the frequency and tie-line power excursion. The robustness of the proposed controller is proved by varying the system parameters.
