IEC TC88 WG27: Wind Turbines - Electrical Simulation Models

The purpose of the IEC working group TC88 WC27 is to define standard dynamic simulation models for wind turbines and wind power plants (i.e. wind farms), which are intended for use in power system and grid stability analyses, and should be applicable for dynamic simulations of power system events such as short circuits (low voltage ride through), loss of generation or loads, and system separation. The proposed work shall develop a standard consisting of two parts with the following scope.
Part 1 shall specify dynamic simulation models for the generic wind turbine topologies/ concepts / configurations on the market. The standard shall define the generic terms and parameters with the purpose of specifying the electrical characteristics of a wind turbine at the connection terminals. In addition the standard shall specify a metrology to create models for future wind turbine concepts.
The standard shall include procedures for validation of the models specified. The simulation models shall refer to the wind turbine connection terminals. The validation procedures shall include tests as specified in IEC 61400-21, Ed. 2, focusing response to voltage dips and set-point requests.
The electrical simulation models shall be developed to the outmost degree of independency from applied simulation tools. If simulation tool considerations are required they shall be separated in the models by a clear tool interface definition.
Part 2 shall specify dynamic simulation models for the generic wind farm topologies / configurations on the market including wind farm control and auxiliary equipment. In addition the standard shall specify a metrology to create models for future wind farm configurations.
The standard shall include procedures for validation of the specified models. The simulation models shall refer to the wind farm point of common coupling.
The electrical simulation models shall be developed to the outmost degree of independency from the applied simulation tools. If specific simulation tool considerations are required they shall be separated in the models by a clear tool interface definition

The working group consists of more than 40 members from more than 15 countries.
