The energy available in a microgrid that is powered by solar energy is tightly related to the weather conditions at the moment of generation. A very short-term forecast of solar irradiance provides the microgrid with the capability of automatically controlling the dispatch of energy. We propose a dataset to forecast Global Solar Irradiance (GSI) using a data acquisition system (DAQ) that simultaneously records sky imaging and GSI measurements, with the objective of extracting features from clouds and use them to forecast the power produced by a Photovoltaic (PV) system. The DAQ system is nicknamed the (Girasol means Sunflower in Spanish). The sky imaging system consists of a longwave infrared (IR) camera and a visible (VI) light camera with a fisheye lens attached to it. The cameras are installed inside a weatherproof enclosure that it is mounted on a solar tracker. The tracker updates its pan and tilt every second using a solar position algorithm to maintain the Sun in the center of the IR and VI images. A pyranometer is situated on a horizontal mount next to the DAQ system to measure GSI. The dataset, composed of IR images, VI images, GSI measurements, and the Sun's positions, has been tagged with timestamps.
由太阳能供电的微电网中可用的能量与发电时刻的天气状况密切相关。对太阳辐照度进行非常短期的预测，能使微电网具备自动控制能量调度的能力。我们提出了一个数据集，用于使用数据采集系统（DAQ）预测全球太阳辐照度（GSI），该系统同时记录天空成像和GSI测量数据，目的是从云层中提取特征并利用它们来预测光伏（PV）系统产生的电力。DAQ系统的昵称是 （Girasol在西班牙语中意为向日葵）。天空成像系统由一台长波红外（IR）相机和一台附有鱼眼镜头的可见光（VI）相机组成。这些相机安装在一个安装在太阳能跟踪器上的防雨外壳内。跟踪器每秒使用太阳位置算法更新其水平和垂直角度，以将太阳保持在红外和可见光图像的中心。一个总日射表位于DAQ系统旁边的水平支架上，用于测量GSI。由红外图像、可见光图像、GSI测量数据和太阳位置组成的数据集已被标记上时间戳。
