Peer-to-peer energy trading of hydrogen-producing prosumers in power distribution network

Abstract

The continuously increasing penetration of distributed energy resources in electric power networks is rapidly making peer-to-peer (P2P) transactions between prosumers and networks the primary market mechanism in recent years. However, hydrogen has emerged as a favored renewable energy source produced by prosumers, which poses considerable challenges to the stable operation of power networks. The present work addresses this issue by developing a distributed trading framework for prosumers that utilize power to hydrogen and heat units. A bi-level optimization framework is proposed to integrate P2P trading with the distribution system operation. Namely, the proposed model considers networks operation constraints to ensure the physical feasibility of distributed P2P trading. The results of numerical computations involving four prosumers connected to an IEEE 33-bus system demonstrate that the proposed model reduces operational costs by 18.93% while decreases daily voltage deviation by 17.7%, enhancing both operating efficiency and security of the distribution network.
