1. 21. Evaluating the accuracy of NEWA, ERA5 and NORA3 in predicting onshore wind conditions: a comparative study using ICOS meteorological mast data in Sweden

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Svetlana Kuru; [2024]
   Keywords : NEWA; ERA5; NORA3; wind speed; wind distribution; correlation coefficient;

   Abstract : The ECMWF Reanalysis v5 (ERA5), the New European Wind Atlas (NEWA), and the 3 km Norwegian Reanalysis (NORA3) are reference datasets that are available for industry and research. The resolution of 3km in both the NORA3 and NEWA datasets sets them apart, while ERA5, with its 31km resolution, continues to serve as a reliable data source that is widely used in the industry.

3. 22. 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

4. 23. Implementation of Dyson equation to accelerate convergence in RS-LMTO-ASA code

   University essay from Uppsala universitet/Materialteori

   Author : Elis Uebel; Viktor Frilén; [2024]
   Keywords : Density functional theory; Dyson equation;

   Abstract : First-principle calculations is a key ingredient for us to understand, improve and design new materials. Density functional theory (DFT) [1] has proven to be a very powerful tool and a number of different versions exist depending on the problem at hand. READ MORE

5. 24. Learning a Grasp Prediction Model for Forestry Applications

   University essay from Umeå universitet/Institutionen för fysik

   Author : Elias Olofsson; [2024]
   Keywords : Forwarder; Autonomous grasping; Deep learning; Multibody dynamics; Convolutional neural network;

   Abstract : Since the advent of machine learning and machine vision methods, progress has been made in tackling the long-standing research question of autonomous grasping of arbitrary objects using robotic end-effectors. Building on these efforts, we focus on a subset of the general grasping problem concerning the automation of a forwarder. READ MORE

6. 25. Peak Load Shaving Strategies of an Office Building : A Case Study at AirSon

   University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Author : Azin Farzam; [2024]
   Keywords : Shifting Peak Load; Electricity Reduction; Measuring Peak Load; Electricity Efficiency; Building Management System; Electricity Consumption.;

   Abstract : Introduction: The global demand for renewable energy is expected to grow annually due to rising electricity consumption and economic and regulatory incentives. Efficient consumption and management of electricity consumption can support this trend (shifting from fossil resources to renewable resources) and benefit companies economically by reducing peak loads, reducing subscription costs, and protecting companies' power systems and networks.
