“…Wind farms support grid voltage with additional reactive current during a voltage dip, as well as via increased reactive power consumption in the event of a voltage dip [18] .The voltage control must take place within 20 ms (one cycle) after fault recognition by providing additional reactive current on the lowvoltage side of the wind turbine transformer, amounting to at least 2% of the rated current for each percent of the voltage dip. [27,28]…”

Wind energy generation, utilization and its grid penetration in electrical grid are increasing worldwide. The wind generated power is always fluctuating due to its time varying nature and causing stability problems. This weak interconnection of wind generating source in the electrical network affects the power quality and reliability. The influence of the wind turbine in the grid system concerning the power quality measurements are the variation of voltage, flicker, harmonics. This paper highlights a brief overview of the stability issues related to integration.

“…The influence of induction machine parameters on induction generator transient stability has been analyzed as well [8]. The stability improvement, realized in the form of longer Critical Clearing Times (CCT), by capacitor banks [9] or STATCOMs [3], on induction generators have been discussed. Further, the performance of STATCOMs to improve system dynamic response has been compared fully with the performance of capacitor and Static VAR Compensators (SVC) [4].…”

Wind farms are becoming important distributed renewable energy resources. However, voltage stability issues with wind farms employing fixed-speed induction generators may require such systems to be augmented with dynamic compensation devices, such as STATCOM units. In preparation for deployment of a 10 MVA STATCOM at an existing wind farm in the Bonneville Power Administration (BPA) system, the STATCOM controller is to be tested through hardware-in-theloop simulation with a real-time digital simulator, which will model both the BPA system and wind farm with high fidelity, transient models. This paper presents groundwork conducted in preparation for the dynamic testing of the controller, including studies of the stability improvement facilitated by the introduction of the STATCOM into the BPA system. The enhancement of voltage stability and induction generator stability by the STATCOM is studied analytically by powervoltage and torque-slip relationships of a simple wind power system, as well as through simulation studies with the real-time simulation to be used for testing of the controller. Simulation results from both approaches are compared and illustrate the potential benefit of the STATCOM in preventing voltage collapse caused by serious network changes, such as opening a line, as well as improvement of the Fault Ride Through capability of the wind power system.
