A Monte-Carlo simulation method for setting the underfrequency load shedding relays and selecting the spinning reserve policy in autonomous power systems

This paper presents a computational method using the Monte-Carlo simulation approach for the calculation of the settings of load shedding underfrequency relays and the selection of appropriate spinning reserve policy in autonomous power systems. The method can be used for comparing alternative strategies by taking into account the amount of load to be shed and the corresponding risk for system stability. This method was applied on a system, that is based on the autonomous power system of the Greek island of Crete and the obtained results are presented and discussed.
