Peer-to-Peer Transactive Network with Shared Energy Storage in Distribution Network

With the development of distributed renewable energy, the power system is gradually becoming a high penetration of renewable energy system. The integration of distributed renewable energy has brought uncertainty to the power system, and the pressure of peak shaving of renewable energy system is increasing rapidly. For the distribution network, shared energy storage(SES) can support the peak shaving needs of distributed renewable energy system, and improve the security and economy of power grid. In this paper, a peer-to-peer transactive network model in distribution network is proposed, which includes renewable generators and communities with SES. A market equilibrium solution based on KKT condition and big-M method is proposed. The simulation results show that renewable generators can benefit from participating in the peer-to-peer transactive network, and communities can benefit from SES.
