Simulation of interaction between wind farm and power system

Abstract

A dynamic model of the wind farm Hagesholm has been implemented in the dedicated power system simulation program DIgSILENT.The wind farm consists of six 2MW NM2000/72 wind turbines from NEG-Micon.The model has been verified using simultaneous power quality measurements on the 10 kV terminals of a single wind turbine and power performance measurements on two wind turbines.The verification shows a generally good agreement between simulations and measurements, although the simulations at higher wind speeds seem to underestimate the power and voltage fluctuations.A way to improve the simulation at higher wind speeds is suggested.
