雾霾对光伏发电量的影响分析

Impact Analysis of Haze on Photovoltaic System's Power Generation

太阳能被看作是抗击雾霾"最有力武器"的清洁能源,但太阳能发电却因雾霾频袭而遭受严峻考验。文中简单介绍了光伏电池的基本原理,分析雾霾对光伏发电量的影响机制。根据相似日原理选出一组相似日,在控制其他影响因素基本相似的条件下,分析雾霾对光伏发电量的独立影响,并通过浙江嘉兴某光伏电站实测数据验证分析结果的可靠性。

Solar energy is regarded as the most powerful weapon to resist haze, while photovoltaic（PV） generations are facing severe challenge due to frequently-occurring haze. In this paper, the basic principle of PV cells is introduced and the mechanism of haze＇s affection to PV output power is analyzed. A group of so called similar days are chosen, and then the standalone affection of haze to PV output is analyzed while other factors are guaranteed to be nearly the same. The actual output power of a certain PV plant in Jiaxing validates the reliability of the proposed method.
