System security and reliabilityProject Gullen Range Wind Farm Field Study
This report shares the results from the Goldwind Field study of Inertia Based Fast Frequency Response at Gullen Range Wind Farm
Goldwind’s Inertia Based Fast Frequency Response (IBFFR) technology was developed to enable wind farms to mimic the behaviour of traditional synchronous generators to provide voltage and fast frequency regulation to improve the network security. Goldwind’s technology uses the rotor kinetic energy (inertia) of the wind turbine blades to boost the power output of wind farm provided in response to a drop in system frequency. A field study of Goldwind’s IBFFR technology was undertaken with the support of funding from ARENA as part of ARENA’s Advancing Renewables Programme.
The Australian Energy Market Operator (AEMO) has been reporting on an ongoing decline in frequency stability in the National Electricity Market (NEM), as shown in Figure 1. The Australian Energy Market Commission (AEMC) has identified one of the main drivers of the recent degradation of frequency performance as generators decreasing or removing the responsiveness of plant to frequency deviations to avoid actual and perceived dis-incentives associated with operating plant in a frequency responsive mode.
