6. Power control strategies for renewable energy systems : The inverter's role in future power systems
Sammanfattning : Connecting more non-dispatchable renewable energy sources (RESs) will result in a higher power variability and a lower system inertia when the synchronous generators are replaced by inverter-connected RES. Inverter control can be divided in three categories: grid-following, grid-forming (GFM) and grid-supporting. LÄS MER
7. Cooling Strategies for Wave Power Conversion Systems
Sammanfattning : The Division for Electricity of Uppsala University is developing a wave power concept. The energy of the ocean waves is harvested with wave energy converters, consisting of one buoy and one linear generator. The units are connected in a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. LÄS MER
8. Thermal Study of a Submerged Substation for Wave Power
Sammanfattning : At the Division of Electricity of Uppsala University, a wave power concept is being developed.It relies on wave energy converters, one buoy and one linear generator placed on the seabed, connected together to a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. LÄS MER
9. Energy Storage Systems in Electrical Distribution Grids : Analysis and implementations of use cases for service stacking
Sammanfattning : This Ph.D. thesis investigates the possibility of using energy storage systems for multiple services by implementing service stacking, with special emphasis on congestion management in distribution grids. LÄS MER
10. Numerical Modelling and Mechanical Studies on a Point Absorber Type Wave Energy Converter
Sammanfattning : Oceans cover two thirds of the Earth’s surface and the energy potential of ocean waves as a renewable energy source is huge. It would therefore be a tremendous achievement if the vast mechanical energy in waves was converted into a form of energy that could be used successfully by society. LÄS MER
