The rational planning of hydrogen production and refueling stations(HPRS)is critical for the development of hydrogen fuel cell vehicles.This paper proposes a method for HPRS planning based on the coupling framework of transportation networks and power grids.The method focuses on site selection and capacity determination of HPRS within large-scale distributed renewable energy integrated power systems.Firstly,by simulating the driving patterns of hydrogen fuel vehicles using an urban road network impedance information model,the spatial-temporal distribution of hydrogen refueling load at the transportation network level is obtained.Then,a multi-objective evaluation-based model for site selection and capacity determination is constructed,taking into account factors such as construction and operation costs,hydrogen refueling load coverage of the transportation network,and power grid stability.The model utilizes an improved particle swarm optimization algorithm to solve for the optimal site selection and equipment capacity of HPRS.The effectiveness of the proposed method is verified through case studies on a 33-node power grid and a 25-node transportation network,demonstrating its ability to reduce power grid losses and voltage deviation caused by HPRS integration,enhance the self-consumption rate of renewable energy,improve the transportation network service quality of HPRS,and reduce construction and operation costs.
