Data-Driven Stability Assessment and Control
NREL develops data-driven stability assessment and control approaches to ensure the reliable operation of power systems with high renewable energy penetrations.
The proliferation of inverter-based resources brings stability challenges, such as low inertia, to power system operations. Traditional model-based stability assessment and control, which require significant computation resources and modeling efforts, will fall short of the fast-changing operation scenarios of power systems with high renewable energy penetrations. NREL research is tackling this challenge from the data-driven angle to explore the potential of massive sensing and measuring data through innovative machine-learning technologies.
- Application of machine-learning technologies to power system dynamic stability assessment
- Data-driven assessment of frequency and rotor angle (transient/small signal) stability
- Data-driven, nonlinear prediction and control to improve stability margin
