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

   University essay from KTH/Energiteknik

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

   Abstract : 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. READ MORE

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

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Joakim Bakklund; [2024]
   Keywords : Technology and Engineering;

   Abstract : 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. READ MORE

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

   University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Author : Gustav Larsson; [2023]
   Keywords : organic solar cells; polymer; morphology; film; AFM;

   Abstract : 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.

6. 5. Estimating Photovoltaic capacity using customs data : Model development of the tool NJORD and photovoltaics' characterization and impact on the African continent

   University essay from Uppsala universitet/Byggteknik och byggd miljö

   Author : Albin Åbrink; [2023]
   Keywords : Photovoltaic; Trade analysis; Development Goals; Africa;

   Abstract : Photovoltaics (PV) is one of the fastest growing power sources in the world in the last twenty years, being the most installed power source in almost half of the world's countries in 2020. Despite this, precise tracking of installations of PV does not exist in most of the world's markets due to PVs unique scalability and modularity. READ MORE
