Assessment of wind farm models from a transmission system operator perspective using field measurements

To understand the impact of increasing penetration of wind energy on power system, dynamic models of wind turbine generator are being incorporated into power system simulation software by transmission system operators. This enables them to carry out security assessment during planning and operations. Unlike synchronous machine-based generators, majority of wind generator models have not been universally standardised and validated. The performance of different wind turbine models (i.e. generic and manufacturer-specific models) under grid disturbance and their cumulative impact as seen by the transmission will need to be completely understood to enable realistic system security assessment. Comparison of these models with actual field measurements is also an attractive option for opportunistic testing. This study will examine model development and its use from the transmission system operator perspective. The generic model will then be compared with detailed individual model for actual wind farm connection studies. The measurement data based on naturally occurring power system disturbance will be used for model validation.
