考虑氢氨储运的综合能源系统两阶段鲁棒优化经济调度OA

[Objective]To address the power imbalance between renewable generation(wind/solar)and load demand,this paper proposes a two-stage robust optimization-based economic dispatch method for integrated energy systems,incorporating hydrogen-ammonia storage and transportation.[Methods]First,to fully exploit the synergistic potential of hydrogen-based short-and long-term energy storage technologies,a hybrid energy storage model is established,integrating electro-thermal storage,short-term hydrogen storage,and seasonal hydrogen storage.Second,to enable large-scale and long-distance hydrogen transportation,a hydrogen-ammonia storage and transportation model is constructed within the hybrid energy storage framework via"hydrogen-ammonia-hydrogen"or"hydrogen-ammonia"conversion processes,enabling both cross-temporal hydrogen storage and cross-spatial transportation.Finally,considering uncertainties on both the source and load sides,a two-stage robust optimization-based economic dispatch model is developed with the objective of minimizing total system costs.[Results]Simulation results demonstrate that,compared with conventional hydrogen storage methods,the proposed approach reduces hydrogen storage and transportation costs while improving renewable energy consumption,system economy,and robustness,thereby verifying its effectiveness and feasibility.[Conclusions]A hybrid energy storage model integrating electro/thermal storage with short-/long-term hydrogen storage is established,enabling spatiotemporal hydrogen utilization,enhancing renewable energy consumption,and reducing operational costs.An innovative ammonia-based hydrogen storage technology is adopted,where the"hydrogen-ammonia-hydrogen"or"hydrogen-ammonia"conversion process lowers storage and transportation costs.By accounting for source-load uncertainty,the system achieves flexible balance between economy and robustness.A current limitation of the model is that it does not integrate the electricity-hydrogen-ammonia with other energy carriers(e.g.,biomass,geothermal)to realize broader multi-energy synergy.
