This paper describes a frequency control using of small-scale power systems is investigated. Utility grids are affected by load and photovoltaic generation fluctuations, which could result in frequency and voltage changes, thereby deteriorating the power quality. Therefore, it is necessary to suppress the effects of these fluctuations on the utility grids. To control a utility grid, we used the conventional proportional-integral controller and a Hinfinity controller, which is one of the recent control methods. Then, we compared and studied both the controls. From the results, it is confirmed that by using the H-infinity control device the frequency fluctuation of power systems can be suppressed when the load fluctuates.
