Analysis and Discussion on the Current State and Demand of Energy Supply for Highway Transportation Facilities

Energy supply is a crucial factor in realizing the future transformation of highway transportation. Determining a comprehensive and sustainable energy supply network that aligns with the demands of future highway transportation facilities - ensuring they are "safe, reliable, environmentally friendly, efficient, and sustainable" - poses a key challenge for current highway developers and operational managers. This study examines the types and energy consumption of significant energy-consuming facilities along expressways. It delves into the current state of power supply and distribution technologies for highway transportation facilities, including low-voltage, medium-voltage, and complementary wind and solar power systems. Additionally, the research analyzes existing issues within power supply and distribution systems for highway transportation facilities. The study investigates the load characteristics and spatial distribution of electricity-consuming facilities along expressways, concluding with an analysis of the future trends in energy demand for highway transportation facilities. This comprehensive exploration encompasses aspects such as the scale of energy demand, the diversification of energy supply, and the need for a secure, efficient, and intelligent energy supply. The findings aim to provide valuable insights for developing innovative, diverse energy supply, and control technologies for safe, efficient, and interconnected highway transportation facilities.
