  1. 11. Harmonisk strömsimulering i inverterbaserade värmepumpar

    University essay from Umeå universitet/Institutionen för fysik

    Author : Alexander Magnusson; [2023]
    Keywords : Current harmonics; inverter-driven compressor; black box simulation;

    Abstract : An electrical distribution network supplies power to many households at a time. Each house has various types of electrical appliances which consume different levels of power depending on its function and the load it supplies. An ideal case would be when no appliances cause power disturbances, however, in reality, many electrical appliances (e.g. READ MORE

  3. 12. Neural Networks for Predictive Maintenance on Highly Imbalanced Industrial Data

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Oscar Montilla Tabares; [2023]
    Keywords : Class Imbalance; Cost Sensitivity; Cost-Sensitive Learning; Focal Loss; Binary Classification; Machine Learning; Deep Learning;

    Abstract : Preventive maintenance plays a vital role in optimizing industrial operations. However, detecting equipment needing such maintenance using available data can be particularly challenging due to the class imbalance prevalent in real-world applications. READ MORE

  4. 13. A Hierarchical Tucker Solver for the Vlasov-Maxwell System

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Oskar Tegby; [2023]
    Keywords : ;

    Abstract : The Vlasov-Maxwell equations is a common model to describe the behavior of a plasma, but come at the cost of their dimensionality since both spatial and veloocity data is stored in three dimensions. This causes a significant obstacle to be able solve them numerically since the size of the data is N^6, which yields a data size of 8. READ MORE

  5. 14. Model Predictive Control for Ground Source Heat Pumps : Reducing cost while maintaining comfort

    University essay from Linköpings universitet/Reglerteknik

    Author : Isak Bokne; Charlie Elf; [2023]
    Keywords : MPC; Model Predictive Control; heat pump control; electricity spot price; weather prediction; reducing cost;

    Abstract : Today, the control of heat pumps aims to first and foremost maintain a comfortable indoor temperature. This is primarily done by deciding input power based on outside temperature. The cost of electricity, which can be rather volatile, is not taken into account. READ MORE

  6. 15. Techno-Economic Optimization and Control of Hybrid Energy Systems

    University essay from Linköpings universitet/Fordonssystem

    Author : Louise Calmered; Tanja Nyberg; [2023]
    Keywords : Hybrid Energy Systems; Optimization; Control Techniques; Peak Shaving; Energy Arbitrage; Ancillary Services;

    Abstract : The increasing demand for renewable energy sources to meet climate targets and reduce carbon emissions poses challenges to the power grid due to their intermittent nature. One potential solution to maintain grid stability is by implementing Hybrid Energy Systems (HESs) that incorporate a Battery Energy Storage System (BESS). READ MORE
