Research on the Interval Calculation of Photovoltaic Power Generation Potential of Provincial Expressways under Multi-Scenario and Multi-Credibility Conditions

Key Points

• This research assesses the photovoltaic power generation potential on provincial expressways under various scenarios and reliability conditions.
• Developed a model for interval calculation of photovoltaic power potential based on generalized road rights theory.
• Analyzed multiple scenarios including service areas, maintenance bases, and slopes of highways.
• Evaluated the energy consumption of maintenance over recent, mid-term, and long-term periods.
• Photovoltaic potential in Hunan's expressways is currently insufficient for annual energy needs, requiring supplementary clean energy.
• By mid-term, significant increases in photovoltaic potential are observed, aiming for basic energy self-sufficiency.
• Long-term plans indicate maximum photovoltaic utilization could lead to surplus energy fed back into the grid.
