1. 6. Linear Modeling of DFIGs and VSC-HVDC Systems

   University essay from KTH/Elektrisk energiomvandling

   Author : Weiran Cao; [2015]
   Keywords : Wind farm; DFIG; VSC-HVDC link; sub-synchronous oscillations; linear modeling; Jacobian transfer matrix; frequency response; PSCAD;

   Abstract : Recently, with growing application of wind power, the system based on the doubly fedinduction generator (DFIG) has become the one of the most popular concepts. Theproblem of connecting to the grid is also gradually revealed. As an effective solution toconnect offshore wind farm, VSC-HVDC line is the most suitable choice for stabilityreasons. READ MORE

3. 7. Dynamic voltage regulation using SVCs : A simulation study on the Swedish national grid

   University essay from KTH/Elektriska energisystem

   Author : Oscar Skoglund; [2013]
   Keywords : Voltage stability; FACTS; SVC;

   Abstract : Voltage stability is a major concern when planning and operating electrical power systems.As demand for electric power increases, power systems are stressed more and more. TheFACTS family of components were introduced to utilize the existing grid to a higherdegree, while still maintaining system stability. READ MORE

4. 8. Power Quality for Distributed Wind Power Generation

   University essay from KTH/Elektroteknisk teori och konstruktion

   Author : Javier Navarrete Pablo-Romero; [2012]
   Keywords : Power quality; wind power; distributed generation;

   Abstract : Wind power often is a source of voltage fluctuations and possible voltage issues are raised when considering interconnecting wind turbines to an electric grid. Also, the power electronics introduced in the wind turbines might insert more fluctuations and different PQ problems. READ MORE

   Abstract : The number of large-scale wind farms integrated to the power system in Sweden is increasing. Two generator concepts that are widely used are Doubly-Fed Induction Generators (DFIG) and Full Power Converters (FPC). READ MORE

6. 10. Doubly-fed Induction Generator Modeling and Control in DigSilent Power Factory

   University essay from KTH/Elektriska energisystem

   Author : Camille Hamon; [2010]
   Keywords : ;

   Abstract : International agreements have set high demands on the share of renewable energy in the total energy mix. From the different renewable sources, significant investments are made in wind power. More and more wind turbines are being built and their number is due to rise dramatically. READ MORE
