摘要

为切实提高现实中信息传输网络的资源利用率，通过分析智能电网环境下弹性光网络中的频谱配置问题，提出了一种结合遗传和蚁群算法优势特点的频谱配置方法，通过衔接策略结合这两种算法的优势，利用遗传算法生成初始解，最后通过蚁群算法正反馈、收敛高效的特点来获得频谱配置问题最优解，从而实现配电通信网的频谱最佳整理效果；提到的优化算法的性能通过软件仿真的方法得到验证。所提算法可优化利用空闲频谱资源，保障配电网海量数据传输的需要，同时可提高配电通信系统的可靠性，对智能电网的安全可靠运行具有重要意义。

Abstract

In order to effectively improve the resource utilization of information transmission network in reality

the spectrum allocation problem in flexible optical network in smart grid environment was analyzed

and a spectrum allocation method was proposed.Combining the advantages of genetic algorithm and ant colony algorithm

the genetic algorithm was used to generate the initial solution.Finally

the optimal solution of the spectrum allocation problem was obtained by the characteristics of positive feedback of ant colony algorithm and efficient convergence.The performance of the optimization algorithm mentioned was verified by software simulation.The proposed algorithm can optimize the use of idle spectrum resources to meet the needs of mass data transmission in distribution network

and improve the reliability of distribution network communication system

which is of great significance to the safe and reliable operation of smart grid.
