1. 16. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Tanmmay Rout; [2023]
   Keywords : Carbon capture; biomass fired combined heat and power plant; MEA based chemical absorption; flue gas; dynamic operation; PI controllers;

   Abstract : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

3. 17. Influence of Varying Electric Light Distribution on Melanopic Equivalent Daylight Illuminance and Lighting Energy Use

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

   Author : Rebecka Ståhl; Parvathy Biju; [2023]
   Keywords : Alertness; Circadian Entrainment; Clear Sky; Correlated Colour Temperature; Daylighting; Direct Electric Lighting; Direct-Indirect Electric Lighting; Energy-Efficiency; Grasshopper; Integrative Lighting; LARK 2.0; Melanopic Equivalent Daylight Illuminance; Overcast Sky; Photopic Illuminance; Spectral Power Distribution.; Technology and Engineering;

   Abstract : Human beings in modern society spend more than 90% of their time indoors to live, work, and socialize. To improve health, quality of life and task performance, integrative lighting is designed to give the right light at the right time at the eye to stimulate circadian entrainment. READ MORE

4. 18. Anomaly Detection in the EtherCAT Network of a Power Station : Improving a Graph Convolutional Neural Network Framework

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

   Author : Niklas Barth; [2023]
   Keywords : Unsupervised Learning; Multivariate Time Series; Graph Convolutional Neural Networks; Anomaly Detection; Industrial Control System; EtherCAT; Power Station; Electricity Grid;

   Abstract : In this thesis, an anomaly detection framework is assessed and fine-tuned to detect and explain anomalies in a power station, where EtherCAT, an Industrial Control System, is employed for monitoring. The chosen framework is based on a previously published Graph Neural Network (GNN) model, utilizing attention mechanisms to capture complex relationships between diverse measurements within the EtherCAT system.

5. 19. Sustainable Production Patterns for Hydropower Units

   University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Author : Hannington Kayanja; [2023]
   Keywords : Automatic control; Hydropower modelling; PD-controller; Sustainable power production; Water level control.;

   Abstract : Globally, a significant portion of energy comes from hydropower. However, harnessing hydro energy interrupts the natural state of river flows, thus affecting the ecological processes of the surrounding communities. READ MORE

6. 20. Parallel Operation of Grid-Forming Power Inverters

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

   Author : Alessia Camboni; [2023]
   Keywords : ;

   Abstract : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. READ MORE
