  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. Enhancements of Positioning for IoT Devices

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Hatem Odetalla; Guoda Tian; [2018]
    Keywords : Internet of Things; IoT; NB-IoT; Narrowband IoT; Positioning; OTDOA; PRS; Positioning Reference Signal; Technology and Engineering;

    Abstract : The aim of this thesis work is to find novel method(s), which enhance the performance of the existing Observed Time Difference of Arrival (OTDOA) positioning technique for Internet of Thing (IoT) devices introduced in Third Generation Partnership Project (3GPP) standard release 14. In this thesis work, NarrowBand IoT (NB-IoT) positioning is considered as the baseline. READ MORE

  3. 3. Sustainable Business for ABB Motors and Generators

    University essay from Chalmers tekniska högskola/Institutionen för teknikens ekonomi och organisation

    Author : Axel Kullander; Johan Malmberg; [2018]
    Keywords : Industrial Marketing; Network Identity; Focal Startup; Network Context; Network Horizon; Sales Channels; Baseload Power; Geothermal Power; Smart Grids; Grid Stabilization; Electrical Machines; Wind Power;

    Abstract : The market for large motors and generators has experienced a decreased demand during the last couple of years following the drop in oil prices in 2014. This follows significant investment in the sector by different actors in 2005-2014, which has resulted in an oversupply of large motors and generators on the market. READ MORE

  4. 4. Reactive power management capabilities of Swedish sub-transmission and medium voltage level grid

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

    Author : Michal Tomaszewski; [2018]
