Inertia Support During Variable Wind Conditions
Paper i proceeding, 2016
Wind variations are important to consider while designing
inertia support strategies. A model has been evaluated but
the findings should reflect issues with several control strategies
utilizing a fixed inertia support pattern.
Wind variability of 0.5 m/s from second to second is observed
in real wind data. However, drastic changes in wind speed can
occur within the duration of inertia support.
An improved inertia control algorithm has been presented
allowing a stable delivery of inertia support from variable speed
wind turbines (VSWT) subjected to realistic wind conditions. The
controller improves the previously presented inertia algorithm
and smoothly transitions from a locked operation window to
The impact of the utilized wind speed filter is described and
its impact on the simulation found to be of great importance.
