Cloud energy storage is one of the most economical energy sharing and coordination technologies in the energy internet in recent years.Considering the operation characteristics of the cloud energy storage,a P2P energy trading ar-chitecture and its operation model are constructed.A distributed alternation direction multiplier method(DADM)is pro-posed for the cloud energy storage objective function considering sharing and virtual integration between single clients,which effectively improves the utilization of renewable energies.The real dataset of renewable energies and real-time e-lectricity prices are analyzed statistically.The simulation results show that the proposed framework can effectively reduce the cost in the long term.
