1. Variation management for cost-efficient integration of variable renewable electricity
Sammanfattning : The aim of this work is to improve our understanding of how wind power and solar photovoltaics (PV) can be integrated into the electricity system in a cost-efficient manner. For this, a techno-economic cost-minimising model of the electricity system is used for a set of case studies. LÄS MER
2. Applications of artificial neural networks for time series data analysis in energy domain
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.

3. Capturing Swedish Industry Transition towards Carbon Neutrality in a National Energy System Model
Sammanfattning : Industry is responsible for approximately 30 % of the total emissions of greenhouse gases, both globally and in Sweden. Given the climate targets set out in the Paris agreement, the industry is facing a challenging future, requiring effective policies to aid the transition. LÄS MER
4. Operability Considerations for Retrofit Design of Industrial Process Energy Systems
Sammanfattning : Energy efficiency is crucial to reduce fuel usage and related emissions in industry. In energy-intensive process industry, the use of heat accounts for a large share of the total energy use and a reduction of the heating and cooling demand is thus important for decreasing energy use.

5. Evaluation of Modular Thermally Driven Heat Pump Systems
Sammanfattning : The building sector accounts for approximately 40% of primary energy use within the European Union, therefore reductions in the energy use intensity of this sector are critical in decreasing total energy usage. Given that the majority of energy used within the built environment is for space conditioning and domestic hot water preparation, prudence would suggest that decreasing primary energy used for these end purposes would have the biggest overall environmental impact.
