Abstract
With the development of smart grid, the requirements of high speed, low delay and better coverage have motivated a electric power wireless network that bridge the communication gaps between the transmission system and the load. In this paper, we introduce a new electric power wireless communication network, and give a general overview of studies on the major characters of communication such as wide coverage, a lot of measurement points in distribution networks as well. In order to improve the communication performance, the paper proposes a modified proportional fair algorithm, which allocates the radio resources by introducing a Quality-of-Service (QoS) scale factor. By comparing with the proportional fair algorithm, we get the conclusion that the modified algorithm is more suitable for the electric power wireless private network.
