Abstract
Aiming at the problems of weak power grid,difficulty in new energy consumption,and low power supply reliability in tunnels of highways with high bridge-tunnel ratios,a smart energy solution based on flexible DC microgrid and all-DC tunnel technology is proposed.By constructing a 1 500V DC microgrid architecture integrating"source-grid-load-storage",and integrating road-area photovoltaic development,transportation-dedicated energy routers,and magnetoresistive sensing energy-carbon management systems,energy self-sufficiency and efficient power supply for highways are achieved.Research results show that this technology can increase the clean energy self-sufficiency rate to over 70％,expand the power supply radius to 40 km,and reduce system losses by 10％,providing technical support for the construction of green and low-carbon highways.关键词
