分布式光伏-公路交通多场景融合发展潜力研究与展望

Research and Prospects on the Integration Potential of Distributed Photovoltaics and Multi-Scenario Development in Highway Transportation

为推动公路交通可再生能源渗透,提高降碳减排效益,在分析公路能源消纳特征、公路光伏资源分布特征、梳理政策现状的基础上,提出了利用公路边坡、服务区、停车场、隧道、路面等多种公路空间资源的分布式光伏规划场景,为公路交通领域的绿电替代与融合提供了技术途径。同时以装机容量、年发电量为指标,评估了现阶段公路领域不同太阳能资源地区、不同应用场景下的分布式光伏资源开发潜力与技术经济性可行性。调研测算结果表明,全国范围内公路边坡场景下的光伏年发电潜力最高,现有案例较丰富,应用前景较好;路面光伏场景装机潜力最大,但受限于现有技术成熟度与经济性,目前现有案例较少,开发程度受限。对于四类不同太阳能资源禀赋地区,Ⅱ类与Ⅲ类地区为公路光伏资源潜力的主要分布地区,其中Ⅲ类地区在各应用场景下的资源潜力最高。

In order to promote the penetration of renewable energy in highway transportation and enhance carbon reduction benefits,in this paper various distributed photovoltaic(PV)application scenarios that utilize different spatial resources along highways,including road slopes,service areas,parking lots,tunnels,and road surfaces are presented.The proposal is based on an analysis of energy consumption characteristics,PV resource distribution patterns along highways,and a review of current policies.These scenarios provide technical pathways for the substitution and integrated development of green electricity in the field of highway transportation.The development potential and techno-economic feasibility of distributed PV resources in different solar resource regions and application scenarios in the highway sector are evaluated by using installed capacity and annual electricity generation as indicators.The research and calculation results show that the development potential of PV resources is higher in highway slope scenarios nationwide,with abundant existing cases and promising application prospects.Road surface PV scenarios has the greatest PV installed potential,but their development is limited due to the maturity and economic viability of current technologies,resulting in fewer existing cases.Regarding the four different solar resource regions,ClassⅡand ClassⅢregions are the main areas with highway PV resource potential,with ClassⅢregions exhibiting the highest resource potential in various application scenarios.
