Peer-to-Peer Energy sharing Among Smart Energy Hubs in an integrated Heat-Electricity Network

Abstract

By increasing the penetration level of the combined heat and power systems and demand response programs between energy consumers in the distribution network, the interaction between electricity and the natural gas network becomes more complicated. This paper proposes a peer-to-peer (P2P) energy sharing scheme for energy trading among Smart Energy Hubs (S.E. Hubs) which can trade both electrical and thermal energy with each other to reduce their cost and, reduce their dependency to gas and electricity utility companies. A two-stage energy strategy is presented. In the first stage, the S.E. Hubs total social cost is reduced by finding the optimal energy sharing profiles. And, in the second stage, we use energy sharing profiles to obtain the optimal payments among S.E. Hubs in a fair manner, which encourages them to participate in energy sharing. The numerical study illustrates that the proposed method significantly reduces the smart energy hubs total social cost by 14%.
