  1. 1. A Model-Predictive-Control Based Smart-Grid Aggregator

    University essay from KTH/Optimeringslära och systemteori

    Author : Amanda Paulus; [2018]
    Keywords : ;

    Abstract : Intermittent energy source usage, such as solar and wind power, is continuously increasing. Intermittent energy sources are highly dependent on prevailing weather conditions, resulting in stochastic electricity generation. The expected stochasticity in electricity generation will cause issues for the current power grid. READ MORE

  2. 2. Microgrid Safety and Protection Strategies

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Aryudha Hartono; [2018]
    Keywords : IB-RES; grid-connected mode; islanded mode; short circuit; IED; directional zero and negative sequence current protection; unbalanced load flow; protection coordination; fault ride-through;

    Abstract : One of the challenging issues with the Microgrid is that the bidirectional power flow providedby the distributed generator (DG) which modify the fault current level. Furthermore, theinverter based-renewable energy source (IB-RES) limits the total fault current contributionto the grid due to its thermal capability. READ MORE

    Author : Sina Borhani; [2018]
    Keywords : Low power circuit; Dynamic Latches; Power consumption; Technology and Engineering;

    Abstract : Suitability of Dynamic Latches for Sub-VT Operation Sina Borhani [email protected] READ MORE

  4. 4. Diffusion MRI of Brain Tissue: Importance of Axonal Trajectory

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Jan Brabec; [2018]
    Keywords : dMRI; diffusion magnetic resonance; axonal trajectory; axonal geometry; undulations; modeling; axons; inverse problem; diffusion spectrum; time-dependent diffusion; Physics and Astronomy;

    Abstract : Obtaining microstructural information non-invasively on brain tissue remains a challenge. Diffusion magnetic resonance imaging (dMRI) is an imaging method that can provide such information. That includes geometrical considerations of nerve cells projections, axons, that are present in the white matter of the human brain. READ MORE

  5. 5. Reducing energy consumption of refrigerators byusing the outside temperature

    University essay from Högskolan Dalarna/Energiteknik; Högskolan Dalarna/Energiteknik

    Author : Maxence Menthon; Léa Van Migom; [2018]
    Keywords : Thermodynamic; Refrigerator; Energy; Climate change mitigation; Mathematical modelling;

    Abstract : Nowadays, many electrical appliances are used daily. The refrigerator is one of them. Consequently, by affecting the energy used by the refrigerator, a huge amount of energy, greenhouse gases (GHG) emissions and money can be saved. It is what this thesis tries to do by applying a concept: using the cold from outside. READ MORE
