We develop and test a data-driven and area-based fast frequency control
scheme, which rapidly redispatches inverter-based resources to compensate for
local power imbalances within the bulk power system. The approach requires no
explicit system model information, relying only on historical measurement
sequences for the computation of control actions. Our technical approach fuses
developments in low-gain estimator design and data-driven control to provide a
model-free and practical solution for fast frequency control. Theoretical
results and extensive simulation scenarios on a three area system are provided
to support the approach.Comment: In proceedings of the 11th Bulk Power Systems Dynamics and Control
