Frequency Response Assessment and Improvement of Three Major North American Interconnections due to High Penetrations of Photovoltaic Generation
- University of Tennessee, Knoxville, TN (United States); Oak Ridge National Laboratory (ORNL), Oak Ridge, TN (United States)
As photovoltaic (PV) generation penetration increases, the inertial and primary frequency response of North American electric grids after a generation loss disturbance will decrease. This change could negatively influence North American power grids frequency stability. This project produced a series of high PV penetration models from detailed, validated base models of all three U.S. interconnections (Eastern Interconnection, Western Electricity Coordinating Council, and Electric Reliability Council of Texas) so that the effects of increased PV generation on their frequency responses can be fully quantified. Mitigation strategies were also developed and validated using both software and hardware test beds.
