Photovoltaic power generation, in specific, is greatly affected by weather factors, which may render power grids susceptible to instability, quality and balance issues. In this context, photovoltaic power generation forecasting is crucial not only to enhance the management of diverse energy sources through generation planning, but also to ensure widespread adoption of photovoltaic energy. To address the predictability issue in generation, this study aims to investigate the combination of satellite data with meteorological data to predict the energy generation potential in photovoltaic panels within 30, 60, 120, and 180-minute horizons. For this purpose, images from the GOES-16 satellite are used in combination with data from a ground-based weather station, located at Florian\u00f3polis &#8211; Santa Catarina &#8211; Brazil. The data is fed to a convolutional neural network, where convolutions are employed to extract features from the satellite images, aiming to establish a relationship with solar irradiation. The output of the convolutional network serves as input for a multilayer perceptron network, which utilizes the data to predict the Global Horizontal Irradiance (GHI). Our results support that models incorporating satellite images provide forecasts approximately 41% better for the 30-minute horizon and 21% better for the 180-minute horizon, when compared to models without satellite images.<\/p>\n<p><strong>Keywords:<\/strong> Photovoltaic power forecasting, deep learning, convolutional neural network, satellite image, GOES-16.<\/p>\n<p><strong>DOI code:<\/strong> <a href=\"http:\/\/dx.doi.org\/10.21528\/lnlm-vol22-no2-art1\">10.21528\/lnlm-vol22-no2-art1<\/a><\/p>\n<p><strong>PDF file:<\/strong> <a href=\"https:\/\/sbia.org.br\/lnlm\/wp-content\/uploads\/2024\/12\/vol22-no2-art1.pdf\">vol22-no2-art1.pdf<\/a><\/p>\n<p><strong>BibTex file:<\/strong> <a href=\"https:\/\/sbia.org.br\/lnlm\/wp-content\/uploads\/2024\/12\/vol22-no2-art1.bib\">vol22-no2-art1.bib<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Luiz Henrique Buzzi , Lucas Weihmann &#038; Pablo Andretta Jaskowiak Abstract: The increasing demand for clean energy presents challenges in energy supply management, largely due to their intermittency.
