摘要:

随着智能电网的发展,配电网通信网络对智能配电网的支撑作用越来越重要。配电网通信业务种类多、通信需求差异大,单一网络无法满足各类通信业务的需求,因此智能配电通信中的异构网络架构十分必要。为了提高配电网运行可靠性,在异构接入网的基础上,综合考虑配电通信网络当前状态和配网业务通信需求,提出了一种基于网络效用的多目标业务逃生策略。该策略针对实时(RT)业务和非实时(NRT)业务需求,根据网络承担负载能力,建立了关于RT业务服务率函数和NRT业务服务率函数的多目标模型,然后利用NSGA-II求解Pareto前端。仿真结果表明,该策略可以在配电通信网络发生故障时保证RT业务和NRT业务配网业务的逃生率及时效性。

Abstract:

With the development of the smart grid,the communication network for distribution grid plays a more and more importantl supporting role in smart distribution grid.There are various types of communication services in distribution grid,and they differ in communication requirements.A single network cannot meet the needs of all of them.Thus,it is necessary to introduce the heterogeneous network architecture into smart distribution.To improve the reliability of distribution grid,a multi-objective escape strategy based on heterogeneous access networks was proposed,which considered the current state of the communication and services requirements.Based on the network capacity,a multi-objective model subjected to the service functions of real-time (RT) and non-real-time (NRT) services was consouctd by this strategy.And then NSGA-II was adopted to get the Pareto front.The simulation results show that the strategy can guarantee the escape rate and timelines of RT and NRT distribution services.

Key words: smart distribution network, access network, service escape
