Planning of Large-scale Wind-Supplied Hydrogen Energy Storage System to Support Zero Energy Buildings in Urban Distribution System

Zero energy buildings (ZEBs) driven by green hydrogen can achieve net-zero carbon emissions and efficient energy utilization in urban buildings. Compared to distributed on-site hydrogen production in ZEBs, large-scale green hydrogen production is more cost-effective. Therefore, we propose a strategy that a large-scale wind-supplied hydrogen energy storage system (HESS) produces and stores hydrogen in a centralized manner while supplies hydrogen to ZEBs in a distributed manner. To fully consider the coordination between the HESS and battery energy storage systems (BESSs) in ZEBs, a seasonal-trend decomposition method is introduced for better analyzing the long-term energy storage effect of the HESS. A scenario-based two-stage stochastic planning model is also proposed in this work to determine the optimal planning capacity of the wind-supplied HESS (including wind turbines, electrolyzer and hydrogen storage tank). The case study results demonstrate that the seasonal-trend decomposition method effectively preserves long-term variation characteristics, leading to a 19.4% reduction in total planning costs compared with the planning results obtained without this method. The planning of the wind-supplied HESS can improve decarbonization and overall economic efficiency of the urban distribution system integrated with ZEBs.
