Abstract:

The state-of-the-art and typical characteristics of the energy interconnection system(EIS)and microgrid are reviewed from the interpenetration and interrelation perspective of the two systems. Six “cell” functions of microgrids to facilitate the future EIS, namely, improving power quality, enhancing reliability and resilience, coordinating energy dispatch among different areas, achieving load active control and bidirectional information flow, and promoting resources utilization efficiency, are further analyzed from the six features of microgrid including deployment localization, source/load diversification, structural diversity, operational flexibility, controllability, and interactivity. In addition, several typical microgrid interconnection types are presented. Finally, key technologies and equipment to promote EIS development in the future are presented and predicted.
