Distributed Power-Generation Systems and Protection [PDF]
Proceedings of the IEEE, 2017 Continuously expanding deployments of distrib¬uted power-generation systems (DPGSs) are transforming the conventional centralized power grid into a mixed distributed electrical network. The modern power grid requires flexible energy utilization but presents challenges in the case of a high penetration degree of renewable energy, among which wind and ...
