考虑固态运氢交互的电氢综合能源系统协同规划OA

[Objective]To address practical issues such as limited transmission channels for large-scale wind-solar bases in desert and arid regions of China and insufficient local consumption,this paper proposes a collaborative planning method for an integrated electricity-hydrogen energy system(IEHS)that considers solid-state hydrogen transport interactions.The method aims to alleviate the coupling bottleneck between renewable energy curtailment and the disconnection across hydrogen production,storage,transport and utilization.[Methods]First,an IEHS model is established,comprising electrolyzers,hydrogen storage tanks,gas-solid conversion units,and hydrogen vehicle loads.Solid-state hydrogen transport vehicles(SHTVs)are introduced to enable efficient interregional hydrogen transport and energy interaction.A bilevel planning model for hydrogen production,storage,transport,and utilization is then formulated.The upper-level objective minimizes equipment capacity configuration costs and the lower-level objective minimizes system operation optimal dispatch costs.The bilevel model is transformed into a single-level linear model using the Karush-Kuhn-Tucker(KKT)conditions and the Big-M method.[Results]The results demonstrate that adopting SHTVs for cross-regional hydrogen interaction reduces annual electricity purchase costs and renewable energy(wind and solar power)curtailment costs.Compared with independent operation in each region,the annual total system cost decreases by RMB 74.79 million,representing a reduction of 17.7％.In addition,relative to hydrogen tube trailer(HT)-based interaction,the annual transport cost decreases by RMB 15.52 million,or 67.9％.[Conclusions]The proposed method facilitates the accommodation of wind and solar power while reducing CO2 emissions by 9,450 t,thereby effectively improving the overall economic and environmental performance of the system.
