Biogeography based krill herd migration (BBKH) optimizer is used in this paper to find the optimal gains of the conventional controllers to enhance the frequency profile of the isolated power system. This model integrated with solar, wind along with conventional thermal and hydro units. Two conventional controllers known as integral (I) and proportional-integral-derivative (PID) controllers are taken to study the frequency control of test system under various loading conditions. Further, primary regulation gains of conventional plants are also considered as decision variables along with controller gains to study the impact of their variations on system frequency. Under regular and random load disturbances, these controllers improve the system frequency profile even the volatile nature of the renewables exist. Comparative assessment of BBKH over other heuristic algorithms shows the improvements in the frequency control of isolated power system.<
