构建坚强智能电网是我国的战略性选择,同时迅速发展的通信技术有利于提高现有电力通信网能力,从而更好的满足坚强智能电网需求。从智能电网需求出发,以电力通信网为切入点,结合软件定义网络技术(software defined network,SDN)的优势和特点,提出引入SDN技术提升电力通信网性能。并结合应用场景分析,说明SDN技术能够提升电力通信网性能,使其更好满足智能电网的需求;展现SDN在智能电网中的应用前景。
Constructing a strong smart grid is a strategic choice in our country. At the same time, the rapid development of communication technologies is conducive to improving the capabilities of existing power communication networks so as to better meet the needs of a strong smart grid. Based on the demand of smart grid and the power communication network, this paper proposes the introduction of SDN technology to improve the performance of power communication network by combining the advantages and characteristics of software defined network (SDN). Combined with application scenario analysis, SDN technology can improve the performance of power communication network to better meet the demand of smart grid; and show the application prospect of SDN in smart grid.
