摘　　要：智能微电网结合通信网络以其高度的灵活性、广泛的适应性、可控的经济性,受到国内外的高度关注。通信约束是影响智能微电网实现综合调度的关键因素,首先简要阐述了包括分层控制和二级控制在内的智能微电网控制结构,对通信网络时延、通信带宽限制和通信链路的不确定性等微电网中常见的通信约束进行了全面的总结,同时,分析了在不同通信约束下智能微电网的二级控制方法,总结了在多种通信约束下智能微电网的稳定性分析方法,最后对这一领域的发展现状和未来的方向进行了讨论和展望。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.
