Architecture and Functions of Micro-grid Energy Management System for the Smart Distribution Network Application

Abstract

Energy management of smart distribution network composed of Micro-grids as the cell units is challenging, it is very important to develop and improve the Micro-grid energy management system (MEMS) to face the distributed generators (DGs) integration. After briefly introducing the elemental functions and architecture of MEMS, which is divided into central energy management system (CEMS) and distributed energy management system (DEMS), the application area and development direction of CEMS and DEMS are analyzed from the viewpoint of their own functional characteristics. Then the MEMS functions are testified by applying to a practical Micro-grid as example, the results of which verified the correctness and effectiveness of the operation strategy in the proposed MEMS architecture.
