  1. 21. PV self-consumption: Regression models and data visualization

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Martos Tóth; [2022]
    Keywords : Self-Consumption; photovoltaics; battery; machine learning; solar energy; random forest; k-nearest neighbor; multi-layer perceptron; lasso regression; ridge regression; linear regression; Egenanvändning; photovoltaics; batteri; maskininlärning; solenergi; random forest; k-nearest neighbors; multi-layer perceptron; lasso regression; ridge regression; linjär regression;

    Abstract : In Sweden the installed capacity of the residential PV systems is increasing every year. The lack of feed-in-tariff-scheme makes the techno-economic optimization of the PV systems mainly based on the self-consumption. The calculation of this parameter involves hourly building loads and hourly PV generation. READ MORE

  3. 22. Exploring Machine Learning Techniques for Short-Term Wind Power Forecasting of Multiple  Wind Parks

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Alexis Tubulekas; [2022]
    Keywords : ;

    Abstract : Wind power is a renewable energy source that is growing rapidly globally. A disadvantage of wind power is its uncertainty as the energy output can vary greatly, a consequence of the stochastic nature of the wind. Accurate forecasts of wind power production can mitigate the problem of uncertainty. READ MORE

  4. 23. Predictions of Electricity Prices in Different Time Periods With Lasso

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Harriet Manninger; Xue Liu; [2022]
    Keywords : Electricity price prediction; linear model; lasso; affecting factors;

    Abstract : When the big data time comes, people also need to keep pace with the times to seek and develop tools that can deal with the vast amount of information. In this project, lassois applied to build parametric models of electricity prices based on different affecting factors. READ MORE

  5. 24. Genome-wide association studies using machine learning

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Mohammad Mshaleh; [2022]
    Keywords : ;

    Abstract : Genom-Wide Association Study (GWAS) is a field that studies the genomics of organisms. GWAS focuses on what is called single nucleotide polymorphisms (SNP). In GWAS,the data of the SNPs is usually massive, which requires modern statistical analysis methods to investigate the relationship between those SNPs and a phenotype. READ MORE

  6. 25. Stacking Ensemble Classification applied to US flight delay prediction during the COVID-19 pandemic

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Patrick Schwarz; [2022]
    Keywords : Stacking Ensemble; Machine Learning; Flight Delays; Classification;

    Abstract : This thesis aims to show that a Stacking Ensemble of multiple base-learners can provide a more accurate prediction of commercial flight delays between the ten largest US airports than the individual prediction models. Three types of machine learning models, namely LASSO, Random Forests and Neural Networks are used as base-learners with different hyper- parameters. READ MORE
