Protective relays are important parts of the power system. The objective of the protection in power systems is to eliminate faults or unacceptable operating conditions for a component and related effects on the network. Fault elimination is usually d

Under Frequency Load Shedding, UFLS, is the last step and the most extreme in protecting electric power systems from black outs and severe damages. Adaptive UFLS methods using df/dt are unreliable. SCADA is too slow to achieve a proper protection of
