DC Distribution Systems and Microgrids — Recommend this title to your library

Thank you

Your recommendation has been sent to your librarian.

In recent years, several demonstration projects using dc microgrids have been implemented across the world due to some distinct advantages of dc over ac systems. The purpose of such initiatives is to validate the theoretically predicted benefits of dc distribution in practical scenarios. This chapter presents a noncomprehensive overview of existing demonstrations and pilot projects for a wide range of applications such as off-grid microgrids, transportation electrification, datacenters, residential and industrial purposes. For each application, key aspects such as architecture, components, control, protection and socioeconomic impacts are highlighted. A short discussion is offered on trends in voltage levels, capacity and topology, progressing toward possible standardization approaches based on recognized best practice.
