1. 1. 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. 2. Calculating the Distance to the Saddle-Node Bifurcation Set

   University essay from KTH/Elektriska energisystem

   Author : Rodrigo Edgardo Borquez Caballero; [2009]
   Keywords : Voltage stability; voltage collapse; saddle node bifurcation; load power margin; transfer capability; continuation methods; continuation power flow.;

   Abstract : A power system will experience voltage collapse when the loads increase up to a certain critical limit, where the system physically cannot support the amount of connected load. This point identified as a Saddle- Node Bifurcation (SNB), corresponds to a generic instability of parameterized differential equation models and represents the intersection point where different branches of equilibria meet.
