Collaborative Operation Between Power Network and Hydrogen Fueling Stations With Peer-to-Peer Energy Trading

Abstract

In recent years, hydrogen fueling electric vehicles (H2EVs) have developed rapidly and drawn much attention. Indeed, the prevalence of H2EVs may introduce a notable interaction between the power network (PN) and the transportation network (TN) via the hydrogen fueling station (HFS). Therefore, it is worth investigating the efficient interaction of PN and HFSs under the constraints of coupled power flow in the PN and traffic flow in the TN. To this end, this article establishes the operation model of HFSs coupled power-traffic system, in order to investigate their impact relationship. Then, a collaborative operation framework with peer-to-peer (P2P) energy trading is proposed to promote the interactive efficiency between the PN and the HFS, considering both energy and reserve. On this basis, the P2P energy trading strategy with dynamic pricing and arbitrage prevention mechanism is developed to further reduce the total operation cost and ensure the fairness of the transaction. Case studies on the HFS-coupled power-traffic system verify the effectiveness of our proposed operation model and the collaborative framework considering P2P energy trading, which results in a lower operation cost, compared with the independent operation and collaborative operation without P2P energy trading, respectively.
