1. Power System Operation Planning and Wind Power Curtailment : Efficient Methods for Power System Scheduling and Integration Studies of Variable Renewable Energy
Sammanfattning : To reduce carbon dioxide emissions, variable renewable energy (VRE) sources are replacing conventional fossil-based power plants for electricity generation. Due to the variability and uncertainty of weather dependent VRE sources, there can be situations when it is not possible to accommodate all the available VRE production, and VRE sources have to be curtailed.

2. Impact of High Levels of Variable Renewable Energy on Power System Generation Adequacy : Methods for analyzing and ensuring the generation adequacy of modern, multi-area power systems
Sammanfattning : The generation adequacy of electricity supply has been an ongoing concern since the restructuring of the industry. Ensuring generation adequacy was a rather straightforward task in the era of natural monopolies. LÄS MER
3. Multilevel Power Converters with Smart Control for Wave Energy Conversion
Sammanfattning : The main focus of this thesis is on the power electronic converter system challenges associated with the grid integration of variable-renewable-energy (VRE) sources like wave, marine current, tidal, wind, solar etc. Wave energy conversion with grid integration is used as the key reference, considering its high energy potential to support the future clean energy requirements and due the availability of a test facility at Uppsala University.

4. Exploring the future low-carbon electricity system: impacts of nuclear power and demand patterns
Sammanfattning : To achieve the climate goals set by the Paris Agreement, the global electricity system is expected to transition towards a low-carbon electricity system. The future low-carbon electricity system is uncertain regarding both generation and demand. LÄS MER
5. Design of Electricity Markets for Efficient Balancing of Wind Power Generation
Sammanfattning : Deploying wind power to a larger extent is one solution to reduce negative environmental impacts of electric power supply. However, various challenges are connected with increasing wind power penetration levels. LÄS MER
