江苏省高速公路站区光伏能源综合利用研究

基于江苏省高速公路沿线服务区、收费站、办公楼屋面面积以及服务区停车场面积统计数据,估算了可利用屋面面积和进行光伏车棚改造的服务区停车场面积。测算了光伏屋面、光伏车棚的装机规模和发电量,结合高速公路用电情况分析了运行方式。经测算:江苏省高速公路服务区和收费站屋面可安装光伏发电总装机容量为32 MW,首年发电量为3200万kWh,全省高速公路光伏屋面25年发电总量约7.3亿kWh;江苏省高速公路光伏车棚可安装光伏发电装机容量约11 MW,25年发电总量约2.5亿kWh;高速公路站区光伏系统所发电量均小于其昼间用电量,站区光伏发电能够以“自发自用”的模式运行。

Study on the comprehensive utilization of photovoltaic energy in the expressway station area of Jiangsu province

Based on the roof area of the service area,toll station,office building and the area of parking lot along the expressway in Jiangsu province,the roof area and parking area available for photovoltaic roofs/carports reconstruction were estimated.The installed scale and power generation of photovoltaic roofs/carports were calculated.The operation mode was analyzed based on the power consumption of the expressway.It is estimated that the available total installed capacity of photovoltaic roofs that can be installed is 32 MW.The power generation capacity of the first year is 32 million kWh.The total power generated in 25 years by photovoltaic roofs along the expressway in Jiangsu province is 730 million kWh.The total installed capacity of photovoltaic carports that can be installed is 11 MW.The total power generated in 25 years by photovoltaic carports is 250 million kWh.The capacity of the photovoltaic system in the station area of the expressway is less than the daytime power consumption,which shows the photovoltaic power generation in the station area can operate in self-use mode.
