Microgrids: a Survey on Technology and Operation
Résumé
In the last years, the importance of Distributed Generation Systems (DGS), and specially, Microgrids (MGs), has increased considerably. The special features of MGs, such as islanding or the use of renewable electrical sources constitutes a new interesting paradigm in electrical networks, whose operation must be optimized. This paper presents a survey in MG's technologies and operation, focused on their architecture, kinds of MG, regulation and management systems and, specially, the islanding. The aim of the paper is to study the state of the art and the problems that must be resolved in order to spread the use of MG.
