A Novel Hybrid Price Mechanism for Regulating the Coupled Power Distribution Network and Transportation Network Based on Feedback Control Method
摘要
Currently, there is a substantial increase in hydrogen fuel cell vehicles (HFCEVs) and battery electric vehicles (BEVs) in transportation networks. The refueling of HFCEVs and charging of BEVs will led to a large-scale construction of integrated hydrogen-electric microgrid charging stations in the future. As a coupling factor, the integrated hydrogen-electric microgrid will deeply couple the new energy power distribution network and the transportation network. However, the uncertainty and randomness of new energy generation, as well as the uncoordinated charging behavior of new energy vehicles, pose severe challenges to the operation of the energy-transportation complex coupled system. How to coordinate and regulate the coupled network to maintain safe and stable operation of the system is a research challenge. This paper proposes a real-time hybrid pricing mechanism based on negative feedback theory for the coordinated regulation of complex networks. Electricity price is to guide the electricity power flow, hydrogen price is to guide the hydrogen power flow, and charging price is to guide the EV travelling. Feedback theory is adopted to update the price. The research results show that the proposed new method can effectively suppress voltage fluctuations in the energy network while also impacting traffic flow in the transportation network.
