LVRT and Stability Analysis of WGS Integrated to Microgrid

The Type-4 wind generation system integrated to Micro-grid through VSC-HVDC link is implemented and the analysis is done by considering a fault on the grid side by the system gets isolated and wind generation system transfers voltage to local load and remote load. When a DC fault is occurred on the VSC-HVDC link then the grid side breaker and wind side breaker gets open, then system gets isolated. The present system considers the“Fault Ride Through” (FRT) conditions, According to the Indian grid code of contact wind generation maintain constant even the voltage collapse is occurred on the grid side. The VSC-HVDC based Type-4 Wind Generation System give more reliable to operate under FRT condition and can meet the Emergency Load demand when the system is under fault condition.
