A Comparison of the Integration Types of Large Wind Farm

The HVAC (high voltage alternate current) and VSC-HVDC (voltage sourced converters based high voltage direct current) are the two main integration types nowadays. In this paper, the HVAC and VSC-HVDC are compared when they are used as the integration method. The test model is built in the PSS/E and its wind power package. The dynamic response is analyzed and conclusions are drawn. It’s clear that in the fault situation the VSC-HVDC can supply the power system with reactive power to help recover the wind farm.
