With the integration of wind power into power system continues to increase, the impact of high penetration of wind power on power system stability becomes a very important issue. Grid integration of wind power plants is complicated by a number of issues, primarily related to wind variability and the electrical characteristics of wind generators. A typical wind plant appears to the grid as a substantially different generation source than a conventional power plant. The most significant difference is that the wind energy source is inherently uncontrollable. Such uncontrolled real power output variations can have an impact on the grid, including frequency variations. In addition, the electrical characteristics of wind generators result in a disturbance response that is naturally different from that of conventional synchronous generators. Without special controls, a wind plant does not inherently participate in the regulation of grid frequency. Frequency control is a particularly significant issue with high level of penetration of wind, in weak system. Wind turbines induction generator absorbs reactive power from the power system, which affects the grid active and reactive power resulting a bus voltage instability and low power factor. As it has been seen that output is variable in wind power generation output, it is going to vary every now and then so as the frequency of the operation is going to get vary, and frequency variation or deviation is to be mitigated to have a smooth power flow output with less variations on the output (within the limits).To have that constant flow of power or to match up with the grid frequency it is required to employ GSC (grid side converter) and RSC (rotor side converter) which is going to work as the slip power recovery system and hence the power from the slip is going to be recovered and used, this is the case in the wind power generation.
