An Overview on Operation and Control of Microgrid

Abstract

A microgrid is a complex network with different distributed generators (DG) and loads operating to provide electrical energy for local loads. It can operate in grid-connected or islanded mode, which has the ability to enhance the reliability and stability of electrical energy supply. Most of micro sources in a microgrid are interfaced through power electronic converters. It is an important task for different types of micro sources to be connected and form a microgrid. A lot of control strategies are used in microgrid to achieve stable and reliable operation and smooth switching between two operation modes.
