Distributed energy network using nanogrid

Abstract

With the guidance of local governments and the concerns of the environment, more and more distributed energy resources (DERs) and distributed energy storage units (DESUs) are installed by subscribers in remote villages, outskirts and mountainous areas. The DERs and DESUs form an easy, self-controlled nanogrid. Nanogrid can be seen as smaller and technologically simpler islanding microgrids. When more and more renewable sources are interfaced to the nanogrid, a power-management issue is important for this system to supply smooth power to the customers. Therefore, some reviews for nanogrid and some representative control strategies for renewable sources in nanogrid are presented in this book chapter.
