Feasibility Analysis of Supply-Demand Matching between Highway Operational Energy Consumption and Renewable Energy Integration: A Case Study of Panzhihua-Dali Highway within Sichuan Province

Highway transportation is one of the main areas of energy consumption and carbon emission, facing great pressure of carbon peak and carbon neutralization. Building a green comprehensive energy system for highway transportation is conducive to dealing with the volatility of renewable energy and other adverse factors, promoting the highway transportation industry to change the energy structure and improve energy efficiency, to reduce carbon emissions. The core of green low-carbon highway transportation is to control resource occupation, reduce energy consumption and reduce carbon emissions. With the construction of green energy and renewable energy systems, it is not only of great significance to guide the construction of green energy and renewable energy systems, but also of great significance to the construction of green energy and renewable energy systems for the operation of new roads. In this paper, aiming at the problems encountered in the current construction of green and low-carbon highways, based on the analysis of the working characteristics of highways during the operation period, combined with the existing classification of highway energy consumption, the highway is divided into seven types of energy consuming facilities according to the scene, such as tunnels, toll stations, operation management centers, maintenance centers and service areas, which are divided into electricity, gasoline, diesel, hydrogen, liquefied gas and water according to the type of energy consumption, The corresponding energy consumption composition system is formed. Taking the energy consumption structure and energy consumption level during the operation period of Panzhihua-Dali highway and the analysis of local new energy collection as an example, the feasibility of matching supply and demand between energy consumption and renewable energy during highway transportation operation is analyzed.
