摘要

本文介绍了沙特电力公司(SEC)总部办公楼屋顶光伏系统的案例研究,该系统容量为277KWp。通过收集2021年光伏系统的发电数据以及建筑物的电力负荷,数据显示,该系统产生的直接馈送给负荷的能量约为404.8兆瓦时。据此计算,光伏发电对能耗的贡献率约为整个建筑负荷的15.7%,总计约为2547.8 MWh。研究表明,这些太阳能电池板产生的电能过剩。该系统通过逆变器进行编程,以保持太阳能电池板的产量等于或小于所连接的电力负荷,因为当时没有将光伏系统与电网连接的规定。光伏发电的剩余能量计算为478.5 MWh。因此,剩余能量为69.1兆瓦时,约占计算光伏发电量的15%。本研究从经济角度对该系统进行了分析,预计该系统的平准化能源成本和投资回收期分别为LCOE= 0.33 SR/kWh = 0.088 USD/kWh,投资回收期为23.9年。

Efficient utilization of solar PV for corporate building in Riyadh, Saudi Arabia
This paper presents a case study for rooftop PV system mounted on corporate building of Saudi Electricity Company (SEC) HQ with a capacity of 277KWp. By collecting the generation data of the PV system along with the electrical loads of the building for the year 2021, the data showed that the amount of energy produced from the system, which was directly fed to the loads is about 404.8 MWh. Accordingly, the contribution rate of the PV system generation to energy consumption was calculated to be about 15.7% of the loads of the entire building, which totaled about 2547.8 MWh. The study showed that there is an excess of electrical energy produced from these solar panels. The system is programmed through the inverter to keep the production of solar panels equal or less than the electrical loads which is connected to due to the absence of the regulation for connecting PV systems with the electric grid at that time. The excess energy of PV generation was calculated as 478.5 MWh. Hence, the surplus energy is 69.1 MWh representing approximately 15% of the calculated PV generation. The study covered the economic perspective for the system by estimating the levelized cost of energy and payback period to be LCOE= 0.33 SR/kWh = 0.088 USD/kWh and Payback period= 23.9 years respectively.
