泛在电力物联网传输网优化关键技术研究

泛在电力物联网作为能源互联网建设的重要基石，对于提升电网综合效能和社会效能，促进满足用户需求的新兴业务的发展具有重要意义。面对新形势、新要求，通过优化泛在电力物联网内部通信网络架构，加快建设泛在电力物联网步伐，实现“能源数据”广泛互联，成了亟待解决的关键问题。本文以泛在电力物联网架构下的传输网为例，分别从网络拓扑结构和路由层面2个角度出发，制定优化策略。从网络拓扑角度出发，提出了基于节点权重的加边优化策略；从路由层面出发，考虑业务均衡性问题，提出了基于边介数的优化路由策略；通过构建网络性能评价指标，将本文提出的优化策略与传统策略进行对比，验证了优化策略能够提升网络的健壮性，扩充网络容量。

Research on Key Optimization Technologies for Transmission Network of Ubiquitous Power Internet of Things

As an important cornerstone of energy Inter-net construction, the construction of Ubiquitous Power Internet of Things is of great significance for improving the comprehensive performance of power grids and social efficiency as well as the promotion of the development of emerging services to meet users' needs. Regarding the new requirements under new circumstances, the optimization of the Ubiquitous Power Internet of things internal communication network architecture has become a key technical issue to be resolved immediately to accelerate the construction of the Ubiquitous Power Internet of Things and achieve the extensive interconnection of “energy data” . Taking the Ubiquitous Power Internet of Things transmission network as an example, this paper develops the optimization strategies from the perspectives of network topology and routing layer respectively. From the perspective of network topology, an edge-added optimization strategy based on node weight is proposed. From the routing level, with the business balance taken into account, an optimal routing strategy based on edge betweenness is proposed. By constructing network performance evaluation indicators, the optimization strategy and traditional strategy proposed in this paper are compared, from which it is verified that the optimization strategy can effectively improve the robustness of the network and expand the network capacity.
