Communication Bandwidth Prediction for Information Gathering Services in Power Distribution and Utilization of Smart Grid
摘要
Abstract
Aiming at limitations of low bandwidth usage ratio in current bandwidth prediction method for information gathering services in power distribution and utilization network, a bandwidth calculation method is proposed to optimize bandwidth ratio based on queuing theory. Firstly, this paper analyses features of power distribution and utilization services in background of Smart Grid, and explains causes of low ratio in current method. Secondly, it depicts a proposed method based on M/M/1/k queuing bandwidth calculation model, including basic idea, implementing steps and diagram for optimal bandwidth calculation, which implements target of maximizing bandwidth utilization-ratio by fully considering dynamic communication features and related QoS (Quality of Service) requirements. Finally, taking electricity information gathering services as example, the paper clarifies rationality of queuing theory method in aspects of supporting quantitative evaluation of QoS to assign bandwidth resource according to related communication network. By using calculation examples from typical information gathering services of State Grid, validity of the proposed method is verified through comparative analysis of current elastic-coefficient-parameter bandwidth prediction method.关键词
