IEC 61400-27 Electrical simulation models for wind power generation Poul Sørensen Risø DTU Roskilde Denmark

Outline of this presentation Scope Participants and meetings Status Timeline TC88 meeting Boulder March 2010

Scope of IEC 61400-27 Define standard dynamic simulation model for wind power Application: Power system and grid stability analysis Applicable for dynamic simulations of Short circuits (fault ride through) Loss of generation or load System separation 2 parts Wind turbines Wind farms TC88 meeting Boulder March 2010

Scope of IEC 61400-27 – part 1 Wind turbine modelling must define: Generic dynamic models for topologies / concepts on market Methodology to create models for new concepts Model parameters Models refer to wind turbine connection terminal Independence on simulation tool To outmost degree With clear definition of interface to simulation tool Validation Shall include tests according to IEC 61400-21 Response to voltage dips Set point requests TC88 meeting Boulder March 2010

Scope of IEC 61400-27 – part 2 Wind turbine modelling must define: Generic dynamic models for topologies / concepts on market Auxiliary equipment Wind farm control Methodology to create models for new concepts Models refer to wind farm point of common coupling Independence on simulation tool To outmost degree With clear definition of interface to simulation tool Validation TC88 meeting Boulder March 2010
