未来配电网面临高比例分布式能源接入及用户互动等多种新需求，而源荷双端的高度不确定性等问题会对当前连通度相对较低的配网拓扑结构带来巨大挑战。目前，蜂巢结构已在通信、计算机、建筑、材料等领域得到广泛应用，其灵活、可靠、扁平化以及易扩展的优点为解决未来配网结构问题提供了新的思路。本项目以应用蜂巢拓扑结构的新型配电网——蜂巢配电网为研究对象，重点解决三个基础问题：1）计及负荷分布与现有网架基础等实际条件，解决蜂巢配电网的非理想结构形态设计问题；2）从图论视角分析蜂巢拓扑对一般网络典型性能的影响机理，揭示不同领域蜂巢网络性能优良的共性原因；3）计及安全、效率、成本、环境等多种因素，量化评估蜂巢结构在远期配电网场景下的优势和不足，科学评价其可用性程度。通过本项目研究，可为未来配电网结构的发展演变提供理论基础和可行方案，提升复杂配电网的灵活性与清洁化水平，实现蜂巢结构在不同学科的应用拓展。

Future distribution networks will be faced with some new requirements, such as the absorption of high-penetration distributed energy resources and demand response. The new problems, such as high uncertainty from both source and load, will cause great challenges to the existing distribution network with relatively weak connectivity. Honeycomb structure has been widely used in communication, computer network, architecture and materials. The advantages of flexibility, reliability, delayering and extensibility provide new ideas to solve the problem of distribution network structure. This project is to study a new topology of future distribution network, that is, honeycomb distribution network (HDN). Three basic problems will be studied. Firstly, design the non-ideal network structure of HDN considering actual load distribution and existing distribution network. Secondly, analyze the influence mechanism of honeycomb topology on the typical properties of general networks in the aspect of graph theory to discover the root cause of the good performance of different honeycomb networks. Thirdly, analyze the advantages and disadvantages of HDN quantitatively considering security, efficiency, cost and environmental benefits then assess the availability degree of HDN in future scenarios. Through this project, it is expected to provide the theoretical foundation and available scheme of the evolution of distribution network structure, improving the flexibility and cleanliness of complex distribution network, broadening the application of honeycomb structure in different research areas.
