Abstract: The purpose of this study is analysis and classified load fluctuations by the type of the power system load. The load fluctuation was appeared in case of unsatisfied the power supply and demand in the power system. It would be decreased the power quality (power system frequency) and stability in the power system. By unstable the power system, it could be occurred the wide power outage. The power system has been changed in the power capacity according to the variety load and increase transmission line capacity. This study is studied the load fluctuations by the type of the power system instability. Technical measures were used to mitigate the load fluctuation and secure the reserve power in the power system. The load fluctuation was examined by analyzing the power usage pattern of the domestic loads. It was shown the mitigation method to the most effective characteristic by the load following with the Governor Free Control (GFC) operation mode of the generator. It was operating by applying the peak mitigating type generator and the Energy Storage System (ESS).
