In order to mitigate the economic burden of Mobile Network Operators (MNOs) and restrict the emission of CO2, a joint power management model powered by hybrid sources is established. It
connects wireless communication system and smart grid by setting price factor reasonably. Besides, a based sleep mechanism named as Energy Cost First (ECF) algorithm is proposed to minimize the energy cost of base station system by deploying the cheapest energy source. The simulation results show that the proposed algorithm can achieve nearly two-thirds energy cost reductions in comparison with the conventional scheme although it consumes a little more electricity. ECF algorithm makes full advantage of renewable energy to reduce the practical power consumption of traditional energy, as a result, it can effectively reduce the expenditure on energy in the wireless communication system and is consistent with the interests of MNOs.
