Parallel Restoration Method for AC-DC Hybrid Power Systems Based on Graph Theory
IEEE Access, 2019 High voltage direct current (HVDC) transmission systems have been used for interconnection among multiple power grids. As a result, the conventional AC power systems are transforming into AC-DC hybrid power systems.

A Novel Sectionalizing Method for Power System Parallel Restoration Based on Minimum Spanning Tree
Energies, 2017 Parallel restoration is a way to accelerate the black-start procedure of power systems following a blackout. An efficient sectionalizing scheme can reduce the restoration time of a system, taking into account the black-start ability, generation-load ...

Parallel Power System Restoration
INFORMS Journal on Computing, 2023 After a blackout event, power system restoration is an essential activity for grid resilience; operators restart generators, re-establish transmission paths, and restore loads. With a goal of restoring electric service in the shortest time, the core decisions in restoration planning are to partition the grid into subnetworks, each of which has an ...

Optimal references for ecological restoration: the need to protect references in the tropics
Perspectives in Ecology and Conservation, 2023 Restoration and conservation are linked by the fact that restoration can help improving, expanding, or connecting protected areas. Here, we argue that conservation can play a critical role for restoration by targeting optimal references, i.e., areas ...
