摘要
公路边坡一般是可达性较高的闲置公共区域,是PV-PGS的理想应用场景,其中光伏发电潜力(PGP)评估是PV-PGS项目规划设计的关键.传统的潜力评价方法主要是基于数字地图和图像处理技术,没有充分考虑公路朝向、坡面几何特征对评价结果的影响.文章提出了一种利用设计或计算的公路和边坡几何参数对公路边坡光伏PGP进行评估的方法,该方法计算公路路线的分段和可用坡度的面积,估计倾斜的太阳辐射,考虑引起光伏系统辐射和能量损失的因素,进而确定公路边坡的光伏发电潜力.
Abstract
Highway slopes are generally idle public areas with high accessibility,which are ideal application scenarios for PV-PGS,in which photovoltaic power generation potential(PGP)assessment is the key to the planning and design of PV-PGS projects.The traditional potential evaluation methods are mainly based on digital map and image processing technology,and do not fully consider the influence of highway orientation and slope geometric characteristics on the evaluation results.This paper proposes a method to evaluate the PV PGP of highway slope by using the geometric parameters of the designed or calculated highway and slope,which calculates the area of the segmentation and usable slope of the highway route,estimates the inclined solar radiation,considers the factors that cause the radiation and energy loss of the photovoltaic system,and then determines the photovoltaic power generation potential of the highway slope.
