Real-time pricing strategy with multi-retailers based on network stability

With the consideration of network stability in the cognitive radio enabled smart grid, this paper proposes a novel real-time pricing strategy with multi-retailers. Firstly, the model of power supply for multiple-retailers is developed, according to users´ demand, retailers´ power supply, and data transmission among multiple-retailers. Secondly, we present an effective real time pricing strategy with the Stackelberg dynamic game model, where the optimal price is obtained by the Nash equilibrium solution. At last, simulation results are shown to prove efficiency of the proposed strategy.
