Research On Performance Evaluation Of Backbone Network For Power Communication

Nowadays,with the rapid development of the energy Internet,the structure of the backbone of the power communication is becoming more and more complex,and the power service is also increasing.The power communication network occupies an important position in the energy Internet and plays an extremely important role in the safe and stable operation of the energy Internet.In order to meet the communication needs of the electric power communication network,communication nodes increasing,the electric power business diversification,only fully consider the nodes of the topology and characteristics of power business and realize the evaluation of important nodes,in order to ensure the safe and stable operation of electric power communication network and the communication quality of the backbone.In view of the above problems,the performance evaluation of backbone transmission network of electric power communication is carried out based on the characteristics of the loop structure of the topology and the characteristics of the power business.First,analyzed the evaluation index of backbone network node importance,according to the particularity of the power ring communication backbone network,the design of a contraction of the minimum node evaluation method based on the evaluation of degree of polymerization into a combination of characteristics of the ring through the network node important degree.Then,on the basis of the characteristics of the network loop,considering the difference of the power business carried by the network link,the importance of the edge weight based on the power business is fully considered,and a business based minimum loop shrinkage node evaluation method is proposed.Finally,by simulating the attack algorithm to complete the simulation,through the simulation experiment,the validity of the proposed method is verified from various aspects,are better to the important nodes in the network to make a correct assessment,provide theoretical support and reference has more practical significance to the development of the power communication backbone network and the reliability analysis study.
