Generic Models for Wind Turbine Generators
There are presently two major industry groups working towards the development of generic
models for use in power system simulations for wind turbine generators – the Western Electricity
Coordinating Council (WECC) Renewable Energy Modeling Task Force (REMTF) and the
International Electrotechnical Commission (IEC) Technical Committee (TC) 88, Working Group (WG) 27.
In general, the most commonly sold and installed technologies in today’s market (both in the US and overseas) tend to be the type 3 and 4 units. All the major equipment vendors supply one or both of these technologies. There are, however, large numbers of the type 1 and 2 units in service around the world, and so modeling them is also of importance. Some vendors do still supply the type 1 and 2 turbines as well.
ETAP includes wind turbine models developed by the WECC Modeling & Validation Working Group & IEC Technical Committee Working Group. These models were developed for analyzing the stability impact of large arrays of wind turbines with a single point of network interconnection. Dynamic simulations have been performed with these models, and comparisons made with results derived from higher-order models used in manufacturer-specific representations of aero conversion and drivetrain dynamics.
