Technology Neutral Quantification of automatic frequency reserve contribution to frequency stability in power systems using Frequency Domain System Identification
· A technology-neutral method is proposed for quantifying frequency dynamics using frequency-domain system identification.
· A reduced second-order-plus-zero model accurately captures the dominant behaviour of complex closed-loop frequency control systems.
· The four SOPZ parameters provide interpretable metrics that enable consistent comparison of diverse reserve technologies.
· A hydropower case study demonstrates the method's ability to quantify reserve contributions and link system dynamics to classical performance indicators.
