1. 16. National Energy System Modelling of Industry : Optimising the Transition Towards Carbon Neutrality

   Författare :Erik Sandberg; Anna Krook-Riekkola; Andrea Toffolo; Åsa Lindman; Peter Lund; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

   Sammanfattning : Industry is a major user of energy and emitter of fossil CO2. At the same time, Sweden targets net-zero greenhouse gas emissions by 2045. Current policies to reduce greenhouse gas emissions and mitigate climate change, and the transition of the energy system it requires, will present major challenges for industry. LÄS MER

3. 17. Numerical and experimental modelling for wave energy arrays optimization

   Författare :Marianna Giassi; Malin Göteman; Jan Isberg; Gregorio Iglesias; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy; Point absorber; Arrays; Parks; Farms; Optimization; Array layout; Genetic algorithm; Cost function; Wave tank experiment; Hydrodynamics; Economical model; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : Many wave power conversion devices, especially point-absorbers, do not provide alone the necessary amount of converted electricity to be cost effective, instead they are designed to be deployed in arrays of many units. Such arrays, or parks, can satisfy a large-scale energy demand, reduce the costs of the produced electricity and improve the reliability of the system. LÄS MER

4. 18. Electrification of Road Transportation - Implications for the Electricity System

   Författare :Maria Taljegård; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; highway E39; CO2 emissions; electric vehicle; electric road systems; energy system modelling; variable renewable electricity;

   Sammanfattning : It is incumbent upon the transport sector to reduce its CO2 emissions by replacing fossil fuels with low-carbon alternatives. Suggested strategies include electrification of the road transport sector through the use of electric vehicles (EVs) with static charging, electric road systems (ERS), and the use of electricity to produce fuels.

5. 19. Applications of artificial neural networks for time series data analysis in energy domain

   Författare :Fan Zhang; Hasan Fleyeh; Stawomir Nowaczyk; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Deregulated energy market; electricity prices; district heating; energy efficiency; neural networks; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

   Sammanfattning : With the development of artificial intelligence techniques and increased installation of smart meters in recent years, time series analysis using historical data in the energy domain becomes applicable. In this thesis, microdata analysis approaches are used, which consist of data acquisition, data processing, data analysis and data modelling, aiming to address two research problems in the energy domain.

7. 20. Towards a learning system for process and energy industry : Enabling optimal control, diagnostics and decision support

   Författare :Moksadur Rahman; Konstantinos Kyprianidis; Anders Avelin; Bengtsson Gunnar; Agostino Gambarotta; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Learning system; Supervisory system; Pulp and paper; Micro gas turbine; Process modelling; Model-based control; Diagnostics; Decision support; Anomaly detection; Fault detection; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Driven by intense competition, increasing operational cost and strict environmental regulations, the modern process and energy industry needs to find the best possible way to adapt to maintain profitability. Optimization of control and operation of the industrial systems is essential to satisfy the contradicting objectives of improving product quality and process efficiency while reducing production cost and plant downtime.
