IEA IA R,DD Wind Energy Annex 21 Dynamic
models of wind farms for power system studies

2
A Generalized Wind Turbine Dynamic Model
INPark model excludes green boxes
3
Structure of a Generalized Wind Park Model
The INPark example, it includes Wind model,
rotor sampling and tower shadow effect, blade
element rotor aerodynamic and geometric
characteristics, flexible blade-hub connection,
2nd order drive train model, 4th order saturation
induction gen., pi-equiv. transmission line
models, ideal trafos and variable capacitors,
local consumers Thevenin equivalent of local
grid (.) uufffff!

Development and Validation of Dynamic Wind Park
Models for Power Systems Studies The IEA Annex
21 contribution
  • Synthesis and conclusions
  • It is possible to develop them.
  • and not that difficult!
  • Physical models give good (validated!!)
  • and replicable results
  • They require detailed and accurate constructive
    wind turbine data from the manufacturer
  • as just any other electric power plant dynamic
    model, by the way
  • In the future and together with power quality
    standards they will enable to prove the
    fulfillment of the (enormous number!) of grid
    code requirements
  • thus, to use them is (will be) much cheaper then
    to use deep experimental testing
