This paper presents a comprehensive
dynamic equivalent model of a wind farm with doubly fed
induction generator wind turbine using back to back
converter. This paper uses a wind farm with different
wind turbines (same wind turbine technology but
different rated power) coupled to the same grid
connection point. It presents a comparative study of four
aggregated modeling techniques, namely, full aggregated
model using equivalent wind speed (FAM-EWS), full
aggregated model using average wind speed (FAM-AWS),
semi aggregated model (SAM), multi full aggregated
model using equivalent wind speed (MFAM-EWS).
Simulation has been carried out for these techniques and
compare them with the complete model using their
different effects such as wind farm power, reactive power
and system dynamics; besides varying the variance effects
on these techniques.
