摘　　要：为解决高速公路新能源自发自用比例低、碳排放高的问题,可在高速公路路域内开发新能源并就近接入服务区的配电或微电网系统。本文针对远区边坡光伏与服务区的配电或微电网系统进行互联场景,提出五种互联方案,并进行技术经济性的对比分析。综合比较,对边坡光伏距离服务区较近场景,建议采用交流互联方案;当边坡光伏较远,建议采用柔直互联技术方案。随着直流变压器等电力电子设备造价的降低,全直流互联方案由于转换效率高,将成为最优选的技术方案。In order to solve the problems of low proportion of spontaneous self use of new energy and high carbon emissions from highway transportation,new energy developed within the highway area can be transmitted to nearby distribution facilities or micro-grid systems of service areas.This article proposes five interconnection schemes and analyzes their technical characteristics and the economic benefits.To conclude,for scenarios where the slope photovoltaic system is closer to the service area,an AC interconnection scheme can be adopted.For the slope photovoltaic system is farther away,it is recommended to use a flexible DC interconnection technology scheme.With the cost reduction of power electronic equipment such as DC transformers,the all DC interconnection scheme will become the most preferred technical solution due to its high conversion efficiency.
