This power production can vary depending on environmental variables, such as temperature, pressure, and humidity. Thus, the business problem is how to predict the power production as a function of these environmental conditions, in order to maximize the profit. The research community has solved this problem by applying Machine Learning techniques, and has managed to reduce the computational and time costs in comparison with the traditional thermodynamical analysis. Until now, this challenge has been tackled from a batch learning perspective, in which data is assumed to be at rest, and where models do not continuously integrate new information into already constructed models. We present an approach closer to the Big Data and Internet of Things paradigms, in which data are continuously arriving and where models learn incrementally, achieving significant enhancements in terms of data processing (time, memory and computational costs), and obtaining competitive performances. This work compares and examines the hourly electrical power prediction of several streaming regressors, and discusses about the best technique in terms of time processing and predictive performance to be applied on this streaming scenario.15460451enginfo:eu-repo/semantics/openAccessjournal article10.3390/en13030740Electrical power predictionCombined cycle power plantStream learningOnline regressionElectrical power predictionCombined cycle power plantStream learningOnline regressionRenewable Energy, Sustainability and the EnvironmentBuilding and ConstructionFuel TechnologyEngineering (miscellaneous)Energy Engineering and Power TechnologyEnergy (miscellaneous)Control and OptimizationElectrical and Electronic EngineeringProject IDinfo:eu-repo/grantAgreement/EC/H2020/783163/EU/Integrated Development 4.0/ iDev40info:eu-repo/grantAgreement/EC/H2020/783163/EU/Integrated Development 4.0/ iDev40Funding InfoThis work has been partially supported by the EU project iDev40.
