Adaptive distance protection for microgrids [PDF]
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015 Due to the increasing penetration of distributed generation resources, more and more microgrids can be found in distribution systems. This paper proposes a phasor measurement unit based distance protection strategy for microgrids in distribution system. At the same time, transfer tripping scheme is adopted to accelerate the tripping speed of the relays

CHALLENGES AND DESIGN ASPECTS OF MICROGRID CLUSTERING
Праці Інституту електродинаміки Національної академії наук України, 2023 With the growing penetration of distributed energy resources, the traditional microgrid concept is evolving into microgrid clustering, which decomposes the distribution system into interconnected microgrids to improve stability,

, 2021 The concept of microgrids goes back to the early years of the electricity industry although the systems then were not formally called microgrids. Today, two types of microgrids can be seen: independent and grid connected. The protection requirement of these two types differs as the protection needs of an independent microgrid are intended for ...
