Abstract

Communication networks for electric system is drawing lots of attention for its indispensable effect in the smart grid. When design an electric dedicated private network in the smart grid, only considering maximum capacity may not be enough. In this paper, we consider an orthogonal frequency division multiple access (OFDMA) two-way relay network in the smart grid. Joint resource allocation is used to get higher spectrum efficiency. A capacity reservation scheme is proposed to guarantee specific kind of service while taking energy efficiency and pollutant emissions into account. Simulation results show that our scheme can improve spectrum efficiency, lower energy cost and significantly reduce pollutant emissions.
