Access selection algorithm of heterogeneous wireless networks for smart distribution grid

针对配电网通信业务的差异性,准确地从异构无线网络中选出合适的通信网络并提高网络资源利用率是配电网高效运行的关键。提出一种面向智能配电网的异构无线网络接入选择算法,考虑不同类型配电业务需求和网络性能,结合灰色关联度和逼近理想解排序法构建相对贴近度模型,将相对贴近度最高的网络作为接入网络。仿真结果表明,该算法能够准确选出满足配电业务需求的接入网络,将配电业务更均匀分布在网络中,改善网络资源利用率。

Aiming at the difference in communication services of distribution network,it is the key for efficient operation of smart distribution grid（SDG）to accurately select the appropriate communication network from the heterogeneous wireless networks and improve the utilization ratio of network resources.An access selection algorithm of heterogeneous wireless networks for SDG was presented.Different types of distribution business requirements and network performance were considered.Relative closeness model combined with gray correlation and technique for order preference by similarity to ideal solution method（TOPSIS）was constructed,and the network with the highest relative closeness was selected as the access network.Simulation results show that the proposed algorithm can accurately select the access network which can meet the demands of distribution business,and the distribution business can be more evenly distributed in networks,while the utilization of network resources can be effectively improved.
