6. Power control strategies for renewable energy systems : The inverter's role in future power systems
Abstract : 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. READ MORE

7. On Deep Machine Learning Based Techniques for Electric Power Systems
Abstract : This thesis provides deep machine learning-based solutions to real-time mitigation of power quality disturbances such as flicker, voltage dips, frequency deviations, harmonics, and interharmonics using active power filters (APF). In an APF the processing delays reduce the performance when the disturbance to be mitigated is tima varying. READ MORE

8. Grid Integration and Impact of a Wave Power System
Abstract : 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. READ MORE

9. Analysis, Modeling and Control of Doubly-Fed Induction Generators for Wind Turbines
Abstract : This thesis deals with the analysis, modeling, and control of the doubly-fed induction generator (DFIG) for wind turbines. Different rotor current control methods are investigated with the objective of eliminating the influence of the back electromotive force (EMF), which is that of, in control terminology, a load disturbance, on the rotor current.

10. Maximizing the integration of wind power in distribution system
Abstract : The global installed capacity of wind power has shown a significant growth, from just 24 GW in 2001 to 283 GW in 2012. This trend is expected to continue for some years to come. Hence a significant amount of wind power needs to be connected to the electric power system. READ MORE
