摘要

摘要 阿尔及利亚是不断致力于制定太阳能开发战略的国家之一,因为它的能力使其成为该领域的先驱。本文选择了位于阿尔及利亚东部 Souk-Ahras 市的 Oued El Keberit (OKP) 光伏电站。该电站的发电能力为 15 兆瓦。我们重点研究了电站的太阳能电池板阵列部分,特别是在标准测试条件 (STC) 情况下,全年在各种室外条件下该电站其中一个分场的性能。研究的重点是已知因素。利用 OKP 光伏电站测量站提供的真实数据,使用 MATLAB Simulink 对光伏电站一个子场的光伏阵列进行了数值建模和仿真。结果显示了辐射强度和温度(无论是低还是高)对光伏系统的短路电流、开路电压、填充因子和效率的影响。请注意,辐射水平对两个重要因素的影响正好相反。夏季的 FF 值最低,但效率值最高。然后,冬季的 FF 达到最大值,但效率却是最低值。这说明它们之间的关系是相反的。另一方面,温度对开路电压的影响正好相反,尤其是当温度高于 25°C 时。

Performance Monitoring and Evaluation of Oued El Keberit Photovoltaic Plant in Eastern Algeria

One of the countries that constantly aim to develop a strategy for the exploitation of solar energy is Algeria, given the capabilities that make it a pioneer in this field. In this paper, we chose Oued El Keberit (OKP) Photovoltaic Plant located in the city of Souk-Ahras, eastern Algeria. The plant has a capacity of 15 MW. We focused on the solar panel array section of the station, specifically examining the performance of one of the subfields in this plant throughout the year under various outdoor conditions, beyond the Standard Test Conditions (STC) case. The study focused on factors that are known. Using a real data presented by the measurement station of the OKP photovoltaic power plant, numerical modeling and simulation of a PV station subfield were performed on the PV array for one subfield of the PV station using MATLAB Simulink. The results show how radiation intensity and temperature, whether low or high, affect the short-circuit current, open-circuit voltage, fill factor, and efficiency of the PV system. Notice that the level of radiation acts on the opposite of two important factors. The FF was at its lowest value in summer, but the efficiency is at its maximum value. Then, the FF in winter reaches its maximum, but efficiency is the lowest value. This means that they have an opposite relationship. On the other hand, the temperature affects the opposite way with open-circuit voltage especially when the temperature is above 25°C.
