Frequency Stability Analysis and Control Considering High Penetration of IBR
Ningchao Gao | Ningchao.Gao@nrel.gov
Abstract: As the penetration of inverter-based resources (IBRs) increases, the power system inertia provided by conventional synchronous generators (SGs) continues to decline. This reduced reliance on SGs for inertia presents significant challenges in maintaining frequency stability, particularly following disturbances. How can these challenges be mitigated? System operators have several potential solutions: 1. Fast Real-Time Generation Dispatch – Scheduling generation resources within short time intervals enables a rapid response to fluctuations in load and renewable generation; 2. Adaptive Frequency Regulation – Procuring services such as secondary frequency regulation (SFR) based on system variations and imbalances helps mitigate power fluctuations and stabilize intra-interval frequency; 3. Enhanced Generation Dispatch with Frequency Stability Constraints – Incorporating fast frequency responses (FFRs) from IBRs into traditional generation dispatch can improve system frequency stability. This seminar will introduce these potential solutions and present analysis results, demonstrating their effectiveness in improving the stability and reliability of power systems.
Dr. Ningchao Gao received her Ph.D. degree in electrical engineering from the University of Denver, Denver, CO, USA, in 2023. Before joining the University of Denver, she was a power system engineer with Shanghai Electric Power Company, part of the State Grid Corporation of China. She is currently a post-doctoral researcher at the National Renewable Energy Laboratory (NREL). Her research interests include power system frequency stability analysis with large-scale IBRs integration, multi-timescale modeling, and advanced pumped storage hydropower (PSH) model development.
