It has the characteristics of safety, self-healing, interaction, compatibility, cleanliness, high efficiency, and high quality. It plays an important role, and its core driving force is to solve energy security and environmental protection issues and address climate change. Smart distribution network is an important part of smart grid and has the basic characteristics of smart grid.

能源环境压力对智能配电网提出了高效运行的需求,智能配电网能够采用多种手段实现高效运行。合理规划和利用分布式电源能够缩小故障影响范围、改善潮流分布、减少能量的远距输送、实现节能减排。合理引导用户参与互动能够改善电网运行水平、降低峰谷差、减少或延缓电网建设投资。分布式电源的出力稳定性和可调可控性较差,渗透率越高电网安全稳定运行的风险就越大。用户的互动行为具有自发性和随机性,使负荷特性的变化难以预测,不加以合理引导将影响电网的安全稳定运行。对智能配电网的高效性进行评估是制定科学建设方案、充分利用分布式能源、促进用户参与互动、引导高效性发展的理论依据,具有理论研究意义和实用价值。The pressure of the energy environment puts forward the demand for efficient operation of the smart distribution network, and the smart distribution network can use various means to achieve efficient operation. Reasonable planning and utilization of distributed power can reduce the scope of fault influence, improve power flow distribution, reduce long-distance energy transmission, and achieve energy saving and emission reduction. Reasonably guiding users to participate in the interaction can improve the operation level of the power grid, reduce the peak-valley difference, and reduce or delay the investment in power grid construction. The output stability and adjustable controllability of distributed power generation are poor, and the higher the penetration rate, the greater the risk of safe and stable operation of the power grid. User interaction is spontaneity and randomness, which makes it difficult to predict the change of load characteristics. Without reasonable guidance, it will affect the safe and stable operation of the power grid. Evaluating the efficiency of smart distribution networks is the theoretical basis for formulating scientific construction plans, making full use of distributed energy, promoting user participation and interaction, and guiding the development of high efficiency. It has theoretical research significance and practical value.
