Abstract：[Background] Highway service areas, as critical nodes for energy supply and consumption in transportation, play a vital role in achieving carbon peak and neutrality goals in the transport sector. [Objective] This study aimed to assess the photovoltaic power generation potential and optimize the system configuration for highway service areas, with the goal of maximizing the energy self-sufficiency rate and operational economy. [Method] A photovoltaic potential assessment model integrating climate zoning and multi-scenario installation characteristics was developed, followed by a mixed-integer linear programming optimization model that coordinated photovoltaic generation, energy storage systems, charging loads, and conventional electricity consumption. [Data] The analyses utilized solar radiation resource distribution characteristics and meteorological data from 34 provincial-level administrative regions, along with conventional energy usage and electric vehicle charging load data from highway service areas. [Result] Under the optimal configuration, the system achieved a 73.8% self-sufficiency rate and reduced annual total costs by 17.7%. [Conclusion] Optimized photovoltaic system configurations can achieve high energy self-sufficiency and significant economic benefits, providing a regional reference and decision-making basis for the low-carbon construction of service areas in different resource zones.
