New energy microgrids constitute a critical development direction for emerging energy business models. The regional road network, primarily composed of national and provincial trunk lines, exhibits distinct characteristics such as clear ownership, extensive spatial coverage, abundant wind and photovoltaic resources, stable energy demand, and significant decarbonization benefits. This makes it a key scenario that aligns with China’s energy transition strategy and ensures energy security [1]. Based on the consensus in China regarding the construction of a “source-grid-load-storage integrated” new power system, this paper investigates the fundamental framework for developing “new energy microgrids” within the regional road network context. Furthermore, it explores an integrated operational model centered on electricity consumption scheduling [2], market transactions, and economic equilibrium. This not only supports the low-carbon transformation and technological innovation of transportation equipment, exemplified by electric vehicles, but also enriches scenarios for integrated terminal energy supply. Additionally, it facilitates traditional industries to achieve fiscal balance through market-oriented transactions of microgrid energy and other means, thereby promoting the healthy and sustainable development of the highway sector.
