Adaptive load shedding and regional protection

International Journal of Electrical Power and 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

Decentralized Adaptive Under Frequency Load Shedding Scheme Based on Load Information [PDF]

IEEE Access, 2019
The inertia of the power system changes when the generators in the system are disturbed or tripped. However, in some systems, there is no control center or communication device falling behind.

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
