Coordinating energy management for multiple energy hubs: From a transaction perspective

Abstract The coupled multiple energy carriers integrated with distributed energy units, e.g., energy converters, renewable energy, and storages have offered energy hubs high flexibility and independent controllability. In this paper, a decentralized transactive based energy management framework enabling coordination among multiple energy hubs (MEHs) is developed. Aiming to improve the economic performance of the interconnected energy hub system, a peer to peer (P2P) transaction platform is established for the self-organized trading of MEH. Particularly, a generic scheme for the generation of transaction prices is specified for the energy hub, which is firstly integrated into a modified alternating direction method of multipliers (ADMM) method for the realization of achieving P2P transaction consensus amongst MEHs. Furthermore, this price scheme offers high traceability of energy-price flows inner EHs operation process and external energy transaction activities, providing transparent price signals in the local P2P market. A three-energy hub system is simulated, and numerical case studies have demonstrated the proposed coordination scheme actively encourages individual EH to enroll in the P2P transaction scheme, offering all EHs a win-win transaction framework and improving the global economic efficiency of the networked system.
