182型和210型光伏组件在平原地区地面光伏电站应用的技术经济性分析

ANALYSIS OF TECHNICAL ECONOMIC OF 182 TYPE AND 210 TYPE PV MODULES APPLIED IN GROUND PV POWER STATIONS IN PLAIN AREAS

“十四五”时期,中国光伏行业得到快速发展,在目前的光伏组件市场情况下,现阶段投资者对采用182型和210型光伏组件的地面光伏电站的平准化度电成本(LCOE)存在一定争议。以山东省青岛市某地面光伏电站为例,选取其中1个3.2 MW光伏方阵为分析对象,利用PVsyst软件建立仿真模型,对其分别采用182型光伏组件和210型光伏组件时设计方案的差异性进行了分析;然后仿真模拟计算了不同设计方案下的光伏方阵首年发电小时数,并从光伏组件投资成本、光伏支架用钢量及投资成本、电缆用量及投资成本等方面,对其LCOE进行了对比分析。研究结果表明:1)采用210型光伏组件时光伏方阵的工程量清单(BOS)成本比采用182型光伏组件时的低0.03018元/W,即单个光伏方阵的投资成本节省了9.7万元;2)采用182型光伏组件的光伏方阵的25年年均发电量比采用210型光伏组件时的高0.5%,二者的发电量差异较小;3)在平原地区地面光伏电站中,同样条件下,采用210型光伏组件时的项目LCOE比采用182型光伏组件时的更优,但两者相差较少。

During the 14th Five Year Plan period,China's PV industry experienced rapid development.In the current market situation of PV modules,investors have some controversy over the levelized cost of energy(LCOE)of ground PV power stations using 182 type and 210 type PV modules.This paper takes a ground mounted PV power station in Qingdao,Shandong Province as an example,selects one 3.2 MW PV array as the analysis object,uses PVsyst software to establish a simulation model,and analyzes the differences in design schemes when using 182 type PV modules and 210 type PV modules respectively.Then,the first year power generation hours of the PV array under different design schemes are simulated and calculated,and the LCOE is compared and analyzed from the aspects of PV module investment cost,PV bracket steel consumption and investment cost,cable usage and investment cost.The research results show that:1)The bills of services(BOS)cost of a PV array using 210 type PV modules is 0.03018 yuan/W lower than that using 182 type PV modules,which saves 97000 yuan in investment cost for one PV array.2)The 25 year average annual power generation of the PV array using 182 type PV modules is 0.5%higher than that using 210 type PV modules,and the difference in power generation between the two is relatively small.3)In ground PV power stations in plain areas,under the same conditions,the LCOE of projects using 210 type PV modules is better than that using 182 type PV modules,but the difference between the two is relatively small.
