Active power control from wind farms for damping very low-frequency oscillations

Timely remote activation of frequency response, provided by converter-based generation, can improve the damping very low-frequency (VLF) oscillations. The research presented is based on both power system models and actual data from phasor measurement units (PMU) Irish system. performance active control (APC) investigated, variations in wind speed, droop, time lag resource capacity demonstrate their effectiveness at wide-spectrum VLF modes. PMU that captures deactivation APC farms analyzed; it demonstrates how effectively dampens modes These observations are supported sensitivity analysis carried out a model DIgSILENT PowerFactory. results improvement mode stability provide generation. It demonstrated minimal amounts generation curtailment modest droop settings sufficient to see substantial damping.
