Smart microgrid combined with communication network has attracted great attention at domestic and overseas for its high flexibility, wide adaptability and controllable economy. Communication constraints are the key factors influencing the microgrid intelligent integrated scheduling. Firstly, the control structure of smart microgrid including hierarchical control and secondary control is briefly described, and the common communication constraints in microgrid such as communication network delay, communication bandwidth limitation and communication link uncertainty are comprehensively summarized. At the same time, the secondary control methods of smart microgrid under different communication constraints are analyzed, and the stability analysis methods of smart microgrid under various communication constraints are summarized. Finally, the development status and future direction of this field are discussed and prospected.
