11. Converter Interfaced Distributed Generation - Grid Interconnection Issues
Sammanfattning : Distributed generation (DG) with a converter interface to the grid is found in many of the green power resources applications. In this thesis, the control of a voltage source converter (VSC), as the DG front end, is in focus regarding the power quality problems that could appear at the connection point. LÄS MER
12. Grid Integration and Impact of a Wave Power System
Sammanfattning : Increasing energy consumption and concern for carbon emissions has boosted the demand for renewable energy production. The focus on renewable energy has gained much attention in wind, solar, hydro and wave power generations. Wave power has great potential due to its high energy density but there are challenges as well. LÄS MER
13. Modeling and Analysis of the Interaction of Batteries and Power Electronic Converters
Sammanfattning : This thesis deals with the interaction of batteries and power electronic converters in automotive applications. Even if the additional heating caused by (unwanted) alternating currents is disregarded, there has been a concern that alternating currents can be harmful for batteries. LÄS MER
