Microgrid: Structures, control methods, standards and challenges [articol]

Abstract

In this paper, the various structures of the microgrid such as AC, DC, Hybrid, Urban DC and Ceiling DC Microgrids are explained. In addition, various energy management schemes are detailed. The benefits, drawbacks and various applications of microgrid structures also showcased with interactive figures and flowcharts. Moreover, to control the various parameters such as voltage, current, and power in MG, different control strategies are discussed. Further, different earthing methods are explained along with the standards like IEEE and IEC which helps in implementation of perfect microgrid system.
