Summary:With the promotion of distributed energy (DG) technologies, microgrid (MG) applications are becoming more and more widespread. To avoid unstable operations caused by the frequent interaction between an individual MG and the external grid, a grid-connected multi-microgrid (MMG) system energy scheduling should be investigated. In this paper, we establish a hierarchical model and scheduling strategy according to the architecture of the MMG system. Based on the Colored Petri nets, we build and simulate a hierarchical energy scheduling model using CPN IDE. Finally, the interacting power data before and after scheduling are obtained and compared, which shows that the model can reduce the interaction frequency between the sub-MG and the external grid, thus improving the stability of the MMG system.
