论文摘要
我们提供了一种方法来估计由于光伏（PV）系统污染损失的方法。我们将这项工作重点放在估计未标记的历史电源生产数据中的损失，即使用时间戳的功率测量，但没有其他信息，例如站点配置或气象数据。我们对这种方法进行了验证，这些方法是在典型的屋顶光伏系统中的一小部分。所提出的方法与先前的工作不同，因为不需要构建性能指数即可分析污染损失。这种方法适合分析分布式屋顶系统机队的现场生产数据中的污染损失，并且非常自动，可以扩展到大型异质PV系统的大型车队。
We provide a methodology for estimating the losses due to soiling for photovoltaic (PV) systems. We focus this work on estimating the losses from historical power production data that are unlabeled, i.e. power measurements with time stamps, but no other information such as site configuration or meteorological data. We present a validation of this approach on a small fleet of typical rooftop PV systems. The proposed method differs from prior work in that the construction of a performance index is not required to analyze soiling loss. This approach is appropriate for analyzing the soiling losses in field production data from fleets of distributed rooftop systems and is highly automatic, allowing for scaling to large fleets of heterogeneous PV systems.
