2018 Sky Images and Photovoltaic Power Generation Dataset for Short-term Solar Forecasting (Stanford Raw)
- Large-scale integration of photovoltaics (PV) into electricity grids is challenged by the intermittent nature of solar power. Sky image-based solar forecasting has been recognized as a promising approach to predicting the short-term fluctuations. Here, we present a curated dataset from Stanford University in a format suitable for solar forecasting related research and applications. The dataset consists of high-resolution (2048x2048) sky images taken by a ground-based fish-eye camera and power output measurements from a 30-kW rooftop PV array approximately 125 meters away from the camera at Stanford Campus, both of which are logged in 1-min frequency. To support the flexibility of research, we also provide the source video footage recorded by the same camera. More details of the dataset can be found in our dataset GitHub repository with link shown in the “Related link” elsewhere on this page. We expect the users of this dataset to process the data based on their own needs, while some reference codes for data processing are provided in our dataset GitHub repository. We hope that the dataset will facilitate the research of image-based solar forecasting and we also encourage the users to explore on other related areas with this dataset, such as cloud classification, cloud image segmentation and cloud movement forecasting. This page includes data from January 2018 to December 2018. Data from 2017 and 2019 are also available. See links to related items elsewhere on this page.
