分布式光伏发电技术在电气化铁路中的应用

Application of Distributed Photovoltaic Power Generation Technology in Electrified Railways

分布式光伏发电技术具有清洁、高效和灵活部署的特点,能够充分利用电气化铁路沿线的闲置土地和车站屋顶,实现清洁能源的本地化生产与消纳,降低铁路运输的碳足迹。目前,分布式光伏发电技术在电气化铁路中的应用主要有3种模式,即“自发自用,余电上网”模式、全额上网模式和“高铁+光伏”模式。结合分布式光伏发电技术在铁路行业的应用现状,分析分布式光伏发电技术在电气化铁路中的应用模式,指出每种模式在实施过程中面临的挑战并提出相应对策,以更好地将分布式光伏发电技术应用于电气化铁路沿线,助力碳达峰碳中和。

Distributed photovoltaic power generation technology has the characteristics of cleanliness,efficiency,and flexible deployment,which can fully utilize idle land and station roofs along electrified railways,achieve localized production and consumption of clean energy,and reduce the carbon footprint of railway transportation.At present,there are three main modes of application of distributed photovoltaic power generation technology in electrified railways,namely the“self use,surplus electricity grid connection”mode,the full grid connection mode,and the“high-speed rail+photovoltaic”mode.Based on the current application status of distributed photovoltaic power generation technology in the railway industry,the application modes of distributed photovoltaic power generation technology are analyzed in electrified railways,the challenges faced by each mode are pointed out in the implementation process,and the corresponding countermeasures are proposed to better apply distributed photovoltaic power generation technology along electrified railways and help achieve carbon peak and carbon neutrality.
