With　the　development　of　clean　energy　technologies　such　as　hydrogen　energy,　public　transportation　systems　are　facing　a　critical　moment　to　switch　to　new　energy　transportation.　Therefore,　this　paper　takes　the　electric-hydrogen　integrated　charging　station　(EHICS)　constructed　by　electrolyzer,　hydrogen　storage　tank,　cold　ironing　(CI),　and　swapping　electricity　compartment　(SEC)　as　the　object　of　research,　and　formulates　the　optimized　configuration　scheme.　Analyze　the　adjustable　characteristics　of　the　SEC　and　CI　in　depth,　and　establish　the　adjustable　mathematical　model　of　battery　and　electric　ship　charging.　The　nonlinear　function　in　the　optimization　model　is　linearized　to　establish　a　mixed　integer　linear　programming　model.　With　the　goal　of　minimizing　the　comprehensive　cost　of　the　system,　the　proposed　configuration　method　can　effectively　improve　the　flexibility　and　economy　of　the　electric-hydrogen　integrated　charging　station　through　the　comparative　analysis　of　different　cases.　©　2024　IEEE.
