【摘要】：发展低碳经济、建设生态文明、实现可持续发展已经成为人类社会的普遍共识。作为能源供应的重要环节,电网的发展模式面临巨大挑战。智能电网成为全球电力工业应对未来挑战的共同选择。高速传输、支持多业务灵活接入的通信网络是智能电网安全、可靠、经济运行的有效保证。而随着通信技术的进步,各种无线通信技术日益成熟,无线网络的覆盖也越来越广泛,未来电网的通信终端将处在多网络覆盖的环境当中。因此研究多网络服务环境下的智能电网通信网络选择算法具有重要意义。面对未来智能电网多网络服务的通信环境,本文系统分析了智能电网对通信网络的特殊要求,详细介绍了智能电网通信网络的研究现状和关键问题。对未来智能电网多网络服务环境下的网络选择算法进行了深入的研究,提出了基于层次分析法的网络选择算法。针对于切换次数高、关键数据传输没有保障的问题,提出基于层级分析法的多决策联合网络选择算法。为了保证关键数据的及时、可靠传输,多决策联合网络选择算法中设置了优先级,对关键信息给予高优先级,提高响应等级。同时设立数据暂存区、使用备用网络传输,可以保证电网中调度控制信息安全、高速、及时的传递。针对于切换次数高的问题,多决策联合网络选择算法运用预判决机制、对网络属性值的动态化设定的方法,在切换次数上予以最低保证。通过仿真实验,该算法在切换次数上有了明显降低,在关键信息的时延和可靠性方面也有更好的质量保证。
[Abstract]:Developing low-carbon economy, building ecological civilization and realizing sustainable development have become the common understanding of human society. As an important part of energy supply, the development mode of power grid faces great challenges. Smart grid has become a common choice for the global power industry to deal with future challenges. High-speed transmission and multi-service flexible access are the effective guarantee for the security, reliability and economic operation of smart grid. With the development of communication technology, various wireless communication technologies are becoming more and more mature, and the coverage of wireless network is becoming more and more extensive. In the future, the communication terminal of power grid will be in the environment of multi-network coverage. Therefore, it is of great significance to study the smart grid communication network selection algorithm in multi-network service environment. Facing the future communication environment of smart grid multi-network service, this paper systematically analyzes the special requirements of smart grid for communication network, and introduces the research status and key problems of smart grid communication network in detail. In this paper, the network selection algorithm in the future smart grid multi-network service environment is deeply studied, and a network selection algorithm based on AHP is proposed. In order to solve the problem of high handover times and unguaranteed key data transmission, a multi-decision joint network selection algorithm based on AHP is proposed. In order to ensure the timely and reliable transmission of critical data, priority is set in the multi-decision joint network selection algorithm, which gives high priority to the key information and improves the response level. At the same time, the data temporary storage area is set up and the backup network is used to transmit the dispatching and control information safely, quickly and timely. In order to solve the problem of high handover times, the multi-decision joint network selection algorithm uses the pre-decision mechanism to set the dynamic property value of the network and to guarantee the minimum number of handoffs. The simulation results show that the algorithm can significantly reduce the number of handoffs and has better quality assurance in terms of delay and reliability of critical information.
