Research and Prospects on the Integration Potential of Distributed Photovoltaics and Multi-Scenario Development in Highway Transportation
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,Class Ⅱ and Class Ⅲ regions are the main areas with highway PV resource potential,with Class Ⅲ regions exhibiting the highest resource potential in various application scenarios.
