1. 1. Study case: The water-cooling effect on floating photovoltaic plants performance

   Master-uppsats, KTH/Energiteknik

   Författare :Alice Dragon; [2024]
   Nyckelord :Solar photovoltaic; Floating photovoltaic; Performance analysis; Thermal loss; Panel Efficiency; Cooling effect; Solceller; Flytande solceller; Prestandaanalys; Termisk förlust; Panelens effektivitet; Kylande effekt;

   Sammanfattning : Floating solar technology is relatively new, and it comes with its own set of challenges and opportunities. This master thesis focuses on understanding how Floating Photovoltaic (FPV) projects perform compared to Ground-Based Photovoltaic (GPV) projects, in specific weather conditions. LÄS MER

3. 2. Local voltage control in a low voltage grid with high photovoltaic penetration

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Joakim Bakklund; [2024]
   Nyckelord :Technology and Engineering;

   Sammanfattning : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. LÄS MER

4. 3. Morphological study of PS/PMMA-matrix on glass, related to vapour pressure, mass-fraction, and size

   Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Författare :Gustav Larsson; [2023]
   Nyckelord :organic solar cells; polymer; morphology; film; AFM;

   Sammanfattning : The objective of this study is to observe how changing amount or ratio between dried mixes of poly-methyl-methacrylate and poly-styrene change the surface appearance, and how the results might inform future design of Organic photovoltaic cells, whom are based on polymer mixtures and heavenly dependent on the arrangement of polymers. An atomic force microscope was used on glass surfaces coated in a poly-methyl-methacrylate/poly-styrene matrix and dried from either dichloromethane or ethyl-acetate to determine surface appearance.

5. 4. Solar Photovoltaic Thermal Collectors and Ground Source Heat Pumps for Commercial Buildings : Case study in Sweden

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Doris Dijak; Elin Torstensson; [2023]
   Nyckelord :Ground Source Heat Pump; Photovoltaic Thermal Collectors; Borehole Thermal Energy Storage; Free Cooling.; Bergvärmepumpssystem; Termiska Solceller; Borrhålsbaserade Termiska Energilager; Frikyla.;

   Sammanfattning : In order to reduce emissions from the building sector, which stands for than a fifth of the global energy consumption today, efficient and fossil free heating and cooling systems are of importance. This study investigates the combination of solar photovoltaic thermal collectors and ground source heat pump systems in order to regenerate energy to the ground in combination with free cooling.

7. 5. CO-LOCATION OF WIND AND SOLAR POWER IN SOUTHERN SWEDEN

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Michail Iakovos Dragasis; [2023]
   Nyckelord :Hybrid renewable energy system; Profitability; Lithium-ion battery storage system;

   Sammanfattning : This paper examines the possibility of adding a photovoltaic(PV) power station to an already planned wind park in terms of profitability. At this time, southern Sweden’s grid is facing a number of challenges and is hurting economic development. Hybrid parks have showed to be able to tackle some of those challenges. LÄS MER
