A topology-based scheme for adaptive underfrequency load shedding [PDF]
2017 IEEE Manchester PowerTech, 2017 This paper presents a topology-based scheme for adaptive underfrequency load shedding (UFLS). By tracking changes of power system topology and information about power flow, the proposed method is able to identify islanded conditions, the number of islands and their deficits of active power, which are fundamental parameters for the adaptive UFLS scheme.

Combination of adaptive and intelligent load shedding techniques for distribution network [PDF]
2012 IEEE International Power Engineering and Optimization Conference, 2012 One of the challenge in islanding operation is to maintain frequency stability when generation is less than demand. This paper presents a new Under-Frequency Load shedding scheme for an islanded distribution network. The scheme is based on an adaptive and intelligent load shedding techniques.

Under voltage load shedding using hybrid ABC-PSO algorithm for voltage stability enhancement
Heliyon, 2021 Voltage collapse tends to occur due to the voltage instability created during large faults. As a last resort, under-voltage load shedding (UVLS) is performed after all the available power operation and control mechanisms have been exhausted.

Adaptive under-frequency load shedding
Tsinghua Science and Technology, 2008 Abstracts Under-frequency load shedding (UFLS) is used in the power industry to rescue systems facing extreme disturbances to avoid system collapse. Traditionally, many computations are repeated to seek the proper power system settings such that the UFLS provides the desired good performance for selected scenarios.
