1. 1. Battery storage implementation in Sweden and sizing software development

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

   Author : Santiago Moreano Rojas; [2023]
   Keywords : ;

   Abstract : Due to the rampant growth of the penetration of renewables into the electrical grids across the world, more challenges appear in the way to assure the optimal operation of the energy system. More particularly, in the case of Sweden, the nuclear power decommissioning tendency and the 100% renewable energy target by 2040, set two strong additional motivations for the rise of issues regarding variability, uncertainty, stability, balancing and quality in the grid.

3. 2. Assessing Offshore Wind System Integration: Comparative Analysis of Floating Photovoltaics, Oscillating Surge Wave Converters, and Battery Energy Storage Systems

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Wilhelm Niilekselä; Douglas Hansson; [2023]
   Keywords : Technology and Engineering;

   Abstract : The high penetration of wind power is increasing the intermittency and power variability into the existing power grid. This is forcing industries to look for optimal configurations in order to improve their systems performance and minimize these effects from the power production method. READ MORE

4. 3. Holistic embedding of equivalent conicity in wheelset maintenance

   University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

   Author : Philipp Linzbichler; [2023]
   Keywords : Railway Operation; Equivalent Conicity; Wheelset Maintenance; Smart Maintenance; Data Analysis; Järnvägsdrift; Ekvivalent Konicitet; Hjulset Underhåll; Smart Underhåll; Dataanalys;

   Abstract : With continuing digitization of railways an increasing number of data is recorded but particularly in operation advanced analysis tends to be partially rudimentary. Yet, it is essential to implement sophisticated processing for all records in order to develop more purposeful and predictive vehicle maintenance strategies that adhere to the increasing requirements imposed by the homologation.

5. 4. Insulation diagnostics of stator bars

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

   Author : Alexandra Garðarsdóttir; [2022]
   Keywords : Electrical insulation system; Stator bars; Insulation testing; Rotating machines; Partial discharges; Acoustic detection; Dielectric response analysis; Break-down test; Tap test; Elektriskt isoleringssystem; Statorstavar; Isolationsprovning; Roterande maskiner; Partiell urladdning; Akustisk detektering; Dielektrisk responsanalys; Nedbrytningstest; Taptest;

   Abstract : Insulation in rotating machines is a common cause for failure. Therefore, research in the area is large and is important to further increase the knowledge of the phenomena related to insulation degradation. READ MORE

6. 5. A feasibility study on production and storage of hydrogen with renewable energy resources at municipal scale

   University essay from KTH/Energiteknik

   Author : Philip Olsson; Martin Tholander; [2021]
   Keywords : ;

   Abstract : The feasibility of a PEM hydrogen storage system in a municipal setting using prosumer excess solar power has been investigated. The feasibility was determined upon key performance indicators payback time, internal rate of return (IRR) and net profit margin. The project was done as a case study on Södertälje municipality, Stockholm, Sweden. READ MORE
