摘　　要：采用PVsyst软件,对光伏阵列倾角与土地成本双因素影响下的光伏发电项目经济性进行了研究和分析,分析了光伏阵列倾角与倾斜面上总太阳辐射量及光伏发电项目实际发电量的关系,计算了不同光伏阵列倾角和不同单位土地租金下光伏场区占地面积、土地年租金,以及光伏发电项目的平准化度电成本(LCOE)。研究结果表明:在光伏阵列倾角及土地成本双因素的共同影响下,随着光伏阵列倾角的增大,项目的LCOE呈先下降后上升的趋势,存在一个光伏阵列倾角使LCOE最优,且该光伏阵列倾角与项目发电量最高时对应的光伏阵列倾角可能不同。不同单位土地租金下,项目的LCOE最优时对应的光伏阵列倾角可能不同,随着单位土地租金提高,项目的LCOE最优时对应的光伏阵列倾角逐渐降低。Using PVsyst software,this paper studies and analyzes the economy of PV power generation project under the influence of two factors of PV array inclination angle and land cost.The relationship between PV array inclination angle and the total solar radiation of inclined plane and the actual power generation of PV power generation project is analyzed.The PV field cover an area,annual land rent and the levelized cost of energy(LCOE)of PV power generation project under different PV array inclination angles and different unit land rent are calculated.The research results show that under the joint influence of the inclination angle of the PV array and the land cost,with the increase of the inclination angle of the PV array,the LCOE of the project tends to decline first and then rise.There is an inclination angle of the PV array that makes the LCOE optimal,and this inclination angle of the PV array is not necessarily the corresponding inclination angle of the PV array when the power generation of the project is the highest.Under different unit land rents,the inclination angle of the PV array corresponding to the optimal LCOE of the project may be different.With the increase of unit land rent,the inclination angle of the PV array corresponding to the optimal LCOE of the project gradually decreases.
