An adaptive approach to setting underfrequency load shedding relays for an isolated power system with private generation

The problem of frequency load shedding in an isolated power system is considered. A proper design of the load shedding scheme should minimize consumer disruption in the case of the load excess and help balance the load to the remaining generation in a system. An adaptive strategy, which can reduce total amount of shed close to the theoretical minimum, is proposed and compared to conventional load shedding scheme.
