Measurement-driven optimal control of utility-scale power systems: A New York State grid perspective

•An optimal control design on a transmission-level model of the New York state grid.•PMU-only design without knowing the full-scale transmission model.•Tools from data analytics, system identification and control theory are used.•Techniques are engineered to improve the dynamic performance of NYS power grid.•Bridges the gap between the design advancements and the implementation opportunities.
