摘要针对现有太阳能与氢能协同的混合能源系统存在系统能量利用率低、能源供需不匹配等问题,提出了全光谱太阳能与氢能利用协同的分布式综合能源架构。考虑太阳能综合输出效果最佳,确立了光谱分频窗口为700~1100 nm。以江苏省南京市某一工业园区为供能对象,通过对园区全年逐时的电、冷、热、生活热水负荷需求进行分析,进行了系统设计,并通过Matlab搭建了全工况动态数字模型。经过模拟仿真得出新系统较参比系统在全年的能量利用率及温室气体减排量上分别提升了10.43%和655660 kg,验证了新系统在能效以及环境友好性方面的优越性。分别探究了太阳能聚光面积和储热装置容量对系统性能的影响规律,在综合考虑系统性能和经济成本下,对新系统开展了容量配置优化,得出了新系统的最佳容量配置是太阳能聚光面积为6000 m^(2),储热装置容量比N_(store)为0.9。经过容量配置优化后,系统的能效达到29.03%,比初始设定下系统的能效提高了3.56%。采用全光谱太阳能与氢能利用协同的分布式综合能源系统,不仅提高了能源利用效率,还有效减少了温室气体排放,为实现可持续发展目标提供了新的思路和方法。 Existing hybrid energy systems using solar and hydrogen often face challenges such as low energy utilization efficiency and mismatches between energy supply and demand.To address these issues,a distributed integrated energy architecture for full-spectrum solar and hydrogen utilization is proposed.Considering the optimal output of solar energy,a spectral splitting window of 700–1100 nm is established.Targeting an industrial park in Nanjing,Jiangsu Province,as the energy supply object,the study analyzed the park’s hourly demand for electricity,cooling,heating,and domestic hot water over the course of a year.A system was designed,and a full-condition dynamic digital model was developed in Matlab.Simulation results showed that,compared to a reference system,the new system improved annual energy utilization efficiency by 10.43%and reduced greenhouse gas emissions by 655660 kg,demonstrating its superior energy efficiency and environmental friendliness.The effects of solar concentrator area and thermal storage capacity on system performance were explored individually.After balancing system performance and economic costs,capacity optimization for the new system was performed,identifying an optimal configuration with a solar concentrator area of 6000 m^(2)and a thermal storage capacity N_(store) of 0.9.Post-optimization,the system’s energy efficiency reached 29.03%,an increase of 3.56%from the initial configuration.This distributed integrated energy system,which synergistically utilizes full-spectrum solar and hydrogen energy,not only enhances energy utilization efficiency but also significantly reduces greenhouse gas emissions,offering a novel approach to achieving sustainable development goals.
