Multi-microgrids System Reliability Assessment Considering Difference Characteristics and Inter-connection Ability Among Microgrids

Connecting neighbor microgrids into a multi-microgrids system (MMS) is one of research hotspots in the field of microgrids. This paper analyzes difference of distributed generators configuration and load types among each microgrid in a MMS. A method to evaluate the influence of dynamic behaviors and energy exchange behaviors on power supply reliability of microgrids in a MMS is proposed in this paper. A reliability assessment algorithm which takes account of connectivity ability among microgrids and intermittence characteristics of distributed energy, different load type and energy exchange behavior is also proposed in this paper. Since the proposed model can characterize dynamic behavior of microgrids in a MMS, the proposed method is of great significance for design and operation of a MMS.
