Study on smart grid communications system based on new generation wireless technology

This paper presents a smart grid communications system based on the new generation wireless technology. Based on the characteristics of new generation broadband wireless communications technologies and wireless communications demands in smart grid, the smart grid wireless communications network is proposed, including three network modes, distributed network based on ROF(radio-over-fiber), cooperative relay network, indoor network based on femtocell (micro-cellular base station) or Wi-Fi. Meanwhile, focusing on applications of smart distribution and electricity, the wireless communications system is proposed, which is an effective solution for the last mile access. And, based on TDD 4G, the experiment of high rate transmission, video on demand, remote monitoring and so on is made. Based on this, the application mode of new generation wireless communications technologies in smart grid is given. The study of new generation wireless communications system and application experiment provides a reference guide for application in smart grid.
