Selection of ongoing or completed research assignments
|date||Project title||Project partners||description|
|Aug 2021||Calculation tools for optimal design of solar parks||Energiforsk, Becquerel Sweden||This research project aims to contribute knowledge on how to design and plan solar parks with higher efficiency and profitability. Currently, there is a lack of tools for solar park designers that take into account local weather conditions, and in particular the price signals from the electricity market and thus, by extension, the balance between production and demand. The project aims to develop a computational model that allows optimising the angle and direction of PV modules based on both local weather conditions and spot price variations over time.|
|Aug 2020 - ongoing||Automatic mapping of solar panels and generation of solar power forecasts from aerial images and machine learning||Becquerel Sweden, Uppsala University, Sweden||The project aims to evaluate whether it is possible to determine where the photovoltaic plants in Sweden are physically installed, their power and design through a system that uses aerial/satellite imagery and an image analysis method that uses machine learning.|
|Sep 2017 - Dec 2020||Member of the Swedish Energy Agency's Strategic Research Council on Solar Power||Swedish Energy Agency||Members of the Strategic Research Council assist the Swedish Energy Agency with input on the focus and focus on the research grants that are announced to, and awarded, swedish research on solar power.|
