1. 1. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

   University essay from Umeå universitet/Institutionen för fysik

   Author : Franz Wikner; [2024]
   Keywords : Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

   Abstract : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

3. 2. Renewable Energy Generation and its Effect on Electricity Prices - A case study of Germany

   University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

   Author : Andreas Lindbom; Natalia Olsson; [2022-07-08]
   Keywords : ;

   Abstract : The implementation of renewable energy sources should, according to economic theory, reduce electricity prices. The main reason behind this is the merit order effect, which describes the sequence of contributions from different power stations. READ MORE

4. 3. A DSO-driven evaluation of a CIM profile : Development of a CIM profile based on use cases related to monitoring Vattenfalls low voltage network

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Louise Persson; [2022]
   Keywords : ;

   Abstract : The transition to more renewable energy sources places high demands on the power systems to be more flexible, and makes it grow in complexity. This has led to a growing need of a common format or language for data exchange in power systems because of the growing number of interconnected networks operated by different companies and utilities that need to communicate on a daily basis.

5. 4. Minimizing Transformer No-Load Losses at Hydropower Plants : A Study of Effects from Transformer Switch-Off During Stand-by Operation

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Elin Luedtke; [2021]
   Keywords : step-up transformer; transformer switch-off; stand-by operation; idle operation; transformer winding; inrush current; fatigue stress; fatigue failure; S-N curve; transformer thermal cycling; thermal time constant; saving potential in hydropower; hydropower plant;

   Abstract : Hydropower is the most important power balancing resource in the Swedish electrical power system, regulating the power supply to match the load. Consequently, several hydropower plants have periods of stand-by operation where the power production is absent but where several devices within a plant are still active. READ MORE

6. 5. WIND POWER PREDICTION MODEL BASED ON PUBLICLY AVAILABLE DATA: SENSITIVITY ANALYSIS ON ROUGHNESS AND PRODUCTION TREND

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Gireesh Sakthi; [2019]
   Keywords : wind resource assessment; wind power prediction model; wind power project; MIUU; wind flow modelling; annual energy production; production trend; wind measurement; power curve; power law exponent; roughness class;

   Abstract : The wind power prediction plays a vital role in a wind power project both during the planning and operational phase of a project. A time series based wind power prediction model is introduced and the simulations are run for different case studies. READ MORE
