含光伏和储氢的电-氢集成化能源站容量配置

CAPACITY CONFIGURATION OF INTEGRATED ELECTRICITY CHARGING AND HYDROGEN REFUELING STATION CONTAINING PHOTOVOLTAIC AND HYDROGEN STORAGE

为适应车辆低碳清洁化的发展趋势,提出一种含光伏和储氢的电-氢集成化能源站架构。考虑光伏出力及负荷需求的不确定性,以年化成本最小为目标,采用模糊机会约束规划建立电-氢汽车集成化能源站容量配置模型。算例分析表明:能源站能充分利用光伏出力,通过电氢耦合满足电、氢负荷充能需求;置信水平越高,所需设备容量越大,年化成本越高;随着制氢效率的提高和氢储能设备价格的降低,可降低购电成本,提高能源站的经济性。

The architecture of an electricity charging and hydrogen refueling station,which contains photovoltaics and hydrogen storage,was proposed for new energy vehicles to adapt to the low-carbon and clean trend.Considering the uncertainty of PV output and load demand,the capacity allocation model of the electric-hydrogen integrated energy station is established by fuzzy chance constraint planning with the objective of minimizing annualized cost.A case study shows that:the energy station can make full use of PV output and meet the electric and hydrogen load charging demand through electric-hydrogen coupling.The higher the confidence level,the larger the required equipment capacity and the higher the annualized cost.With the improvement of hydrogen production efficiency and the reduction of hydrogen storage equipment price,the power purchase cost can be reduced and the economy of the energy station can be improved.
