2. Application of harmonic injection method to analyse Sub-Synchronous Control Interactions (SSCI)
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Wind farms are commonly connected to the main grid through compensated lines which increases the power transfer capability of the line. Double Fed Induction Generator (DFIG) wind turbines in connection to compensated lines can experience Sub-Synchronous Control Interaction (SSCI) which can bring system quantities above allowed levels.

3. Damping of sub-synchronous control interactions with a STATCOM : Wind farms & series compensated power lines
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : The power converter is one of the key components in power system applications such as high voltage direct current (HVDC) systems and the grid connection of intermittent sources such as wind and solar power. However, the increased penetration of converter-based generation introduces challenges, such as sub-synchronous interaction between the converter control system and the grid. READ MORE

4. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study
University essay from Högskolan Dalarna/Institutionen för information och teknikAbstract : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. READ MORE

5. The Impact of Voltage Dip Characteristics on Low Voltage Ride Through of DFIG-based Wind Turbines
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In last decade, there is a large increase in installed capacity of wind power. Asmore wind power is integrated into utility networks, related technologychallenges draw much attention. The doubly fed induction generator (DFIG) isthe mainstream choice for wind turbine generator (WTG) in current market andthe object of this thesis. READ MORE
