Abstract System integrity protection schemes safeguard electric power systems' overall
integrity, among which under-frequency load shedding carries a flagship role. Although …

Everywhere, typical network systems are challenging two opposite situations, mainly caused
by suppliers and consumers. The provision of new power quality resources and an increase …

Technology advancement for renewable energy resources and its integration to the
distribution network (DN) has garnered substantial interest in the last few decades …

Severe generation outages may affect the power system frequency stability and cause
abnormal frequency declines especially under the high penetration of low inertia generation …

As power systems continue to expand, the need arises for more robust monitoring, control
and protection techniques especially under abnormal conditions. In the event of generator …

This paper presents a review of the state of the art of UFLS schemes for isolated power
systems. Isolated power systems are especially sensitive to power imbalances and …

Islanding operation in a distribution network connected to Distributed Generations (DGs) has
the advantage of being able to continuously supply power to the loads even when …

Abstract The integration of Distributed Generation (DG) units in the existing power system
has made the reliable operation of the system more complex. This has necessitated a …

Severe disturbances in a power network can cause the system frequency to exceed the safe
operating range. As the last defensive line for system emergency control, under frequency …

A blackout is usually the result of increasing load beyond the transmission capacity of the
power system. One of the main reasons for power blackouts is voltage collapse. To avoid …
