Adaptive Voltage-Based Load Shedding Scheme for the DC Microgrid
IEEE Access, 2019 The direct current (DC) microgrid requires a fast load shedding scheme that prevents instability and voltage collapse when the distributed energy resources are unable to meet the power demand.

Adaptive load shedding and regional protection
International Journal of Electrical Power & Energy Systems, 2009 The requirement for improved efficiency whilst maintaining system security necessitates the development of improved system analysis approaches and the development of advanced emergency control technologies. Load shedding is a type of emergency control that is designed to ensure system stability by curtailing system load to match generation supply. This

Underfrequency Load Shedding Strategy With an Adaptive Variation Capability for Multi-Microgrids
IEEE Access, 2023 Multi-microgrids (MMGs) suffer from power shortages due to the loss of utility grid support when an unintentional transition occurs. This imposes a transient shock on the system voltage and frequency. To maintain the frequency stability and power balance

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.

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.

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.
