Smart Grid (SG) is an efficient technology for electrical power distribution and management by incorporating two-way communications between utilities and customers. The versatile features of Cognitive Radio (CR) technology meet the requirements of SG communication and have drawn much attention. In this paper, the authors study the On-Demand cognitive radio communication for SG. Their contributions includes two components: a CR communication-driven SG power scheduling called Power Difference Coding (PDC) scheme is proposed to achieve efficient CR communications and optimal power distributions; the behaviors of SG power scheduling over cognitive radio networks are firstly modeled.
