1. 1. Local Voltage Control in Converter Based PV Generation

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Charlotta Sporre; [2024]
   Keywords : distributed generation; active network management; low voltage distribution network; delta control; voltage control; Technology and Engineering;

   Abstract : As the world is trying to rid itself of its dependence on fossil fuels, the need for renewable energy is rapidly increasing. In the power distribution network (DN), this takes the form of distributed generation (DG) from renewable sources, such as photovoltaic (PV) power production. READ MORE

3. 2. Techno-economic analysis and simulation of low temperature district heating networks

   University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Author : Ilia Iarkov; [2023]
   Keywords : Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

   Abstract : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. READ MORE

4. 3. Shape depiction using Local Light Alignment : Evaluating the shape enhancement capabilities of the Local Light Alignment technique at multiple scales

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

   Author : Edvard Ahlsén; [2023]
   Keywords : Shape depiction; Non-photorealistic rendering; Shading; Multiple scales; Formskildring; ickerealistisk rendering; skuggning; skalrymdsmetoder;

   Abstract : Local Light Alignment is a new shading based technique in the field of shape depiction, a field which concerns itself with techniques to represent and enhance the three-dimensional (3D) shape of objects in two-dimensional (2D) visual media. The main idea of Local Light Alignment is to locally adjust the incoming direction of light to create contrast in a way that enhances the perception of shape and surface detail. READ MORE

5. 4. Centering farmer perspectives on a dry-fertiliser made from human urine: a case study on Gotland, Sweden

   University essay from Lunds universitet/LUCSUS

   Author : Nicola Parfitt; [2023]
   Keywords : circular nutrient economy; human urine fertiliser; ecological sanitation; eutrophication; sustainability science; Social Sciences;

   Abstract : To reduce eutrophication and close the nutrient loop between sanitation and agriculture, innovations to recycle human waste are being further developed. As there is little research on Swedish farmer perspectives towards human urine fertilisers, this study investigates Gotlandic farmer perspectives on a dry-fertiliser derived from human urine, developed by Sanitation360.
