A reproducible framework for comparing the controllability of wind power in Europe and the CIS (Commonwealth of Independent States) is proposed, integrating regulatory settings and power system dynamics. The methodological basis includes: a contour model of frequency control, a formal assessment of short-term forecasts with bootstrap intervals, status-coding of the reserve product line into an institutional readiness index, and an analytical relationship between full activation time (FAT) of reserves and imbalance. The comparison is carried out along two axes: standardized FAT values for the EU and scenario-based ranges for the CIS.
