Performance enhancement of wind farm with distribution static compensator

In this paper, dynamic performance of wind farm comprising of three Squirrel Cage Induction Generators (SCIG) is analyzed for grid connected operation. Wind integration causes power imbalances and power system dynamics leading to system instability. The SCIG based wind turbine requires reactive power for magnetization which causes shortage of reactive power in distribution system and hence causes losses that lead to instability of power system. The behavior of the system is analyzed with variation in wind speed, unbalanced and nonlinear loads and three phase fault. The DSTATCOM is being used to improve the performance of wind farm as per the standard of grid code. The grid code demands that power plant of any kind should support electricity network throughout their operation. The performance enhancement mainly involves the power quality issues and grid stability and fault ride through (FRT) capability. A complete power balance analysis of the proposed system is presented under different operating conditions.
