21. Made in Canada : The strategies, spaces and working lives of independent designers in the Canadian fashion system
Abstract : Drawing on 87 interviews with independent fashion designers and key informants, this thesis is a collection of papers which aim to explore the strategies, spatial dynamics and working lives of independent fashion designers in the Canadian fashion industry. The majority of fashion design firms in Canada are small independent businesses, typically run by an individual or pair of designers, with few employees. READ MORE

23. 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

24. Modeling of Wind Turbines for Power System Studies
Abstract : The power quality impact of wind turbines on the electric grid and the response of the wind turbines to faults in the electric grid are investigated in this thesis. A detailed model of a stall-regulated, fixed-speed wind turbine system capable of predicting the flicker impact on the connected grid is presented and compared with field measurements. READ MORE

25. Frequency response by wind farms in power systems with high wind power penetration
Abstract : The integration of variable speed wind turbines (VSWT) in power systems is increasing in order to reduce the emission of green house gases. This increase of power electronic converter interfaced generation causes a decrease of power system inertia, increasing the risk of load shedding and system frequency instability. READ MORE
