1. Closed-loop control and data- recording of a modular-multilevel converter (MMC)
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI. READ MORE

2. Optimal collection grid and transmission line topology for the grid connection of an offshore multi-source park.
University essay from Uppsala universitet/ElektricitetsläraAbstract : As spacial restrictions become more and more of an issue for renewable energy parks onshore, more developers are turning offshore to develop future production. The desire for a diversity of energy sources combined with a desire to utilize space efficiently has sparked an interest in renewable energy parks where more than one energy source occupy the space.

3. Evaluation of DC Fault Current in Grid Connected Converters in HVDC Stations
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : The main circuit equipment in an HVDC station must be rated for continuous operation as well as for stresses during ground faults and other short circuits. The component impedances are thus selected for proper operation during both continuous operation and short circuit events. READ MORE

4. Transmission Systems for Grid Connection of Offshore Wind Farms : HVAC vs HVDC Breaking Point
University essay fromAbstract : Offshore wind is rapidly growing and optimised grid connections are crucial for its success. Generally, costs and losses are higher for HVDC at short distances due to the converters, while HVAC costs and losses increase more rapidly with distance due to the ac cables. READ MORE
