Based on an advanced distributed real-time platform named Real-Time Laboratory (RT-LAB), the impacts of the static synchronous compensator (STATCOM) on wind power system dynamics is studied in this paper. Firstly, a small-scale wind farm model based on squirrel-cage induction generator (SCIG) is built in MATLABTM/Simulink environment. This model is then rebuilt to be suitable for the real-time operation...
In Europe, China and around the world many large wind farms have been installed and more have been planned. The wind farm installations must meet the Grid Code requirements for connections. Many difficulties have been encountered in meeting these requirements, especially for fault ride through, active power and frequency control, reactive power and voltage control requirements. This paper reviews...
STATCOMs are used for voltage support to improve power and voltage quality. Their capability for delivering real power is negligible and this limits their ability to improve the system stability margin. Supercapacitors are devices which can store and quickly release significant amounts of energy, and are now finding application in many power applications. This paper describes how supercapacitor based...
The paper considers a solution for integration of large offshore doubly fed induction generator-based wind farms with a common collection bus controlled by a STATCOM into the main onshore grid using line-commutated high-voltage dc connection. A design procedure is described and the controlled system is validated using PSCAD/EMTDC simulations confirming high performance of the proposed control strategy...
