The co-tier and cross-tier interferences become serious when the electric power communication networks are deployed densely in the coverage area of the primary network base station (PBS). To reduce the co-tier interference in the electric power communication networks and guarantee the quality of service of the primary networks users (PUEs), we propose a distributed power control method. First, a reasonable interference threshold of the PBS is chosen to guarantee the PUE's transmission requirement. Then, a fictitious power-price game with interference compensation is employed to update the power of gateways in smart grid on the condition of the interference threshold. Finally, a modified distributed power control method is proposed to protect the primary network link. Simulation results show that the co-tier interference among gateways is reduced efficiently, the target signal-to-interference plus noise ratio of the PUEs can be achieved, and the network performance is improved.
