Novel Coordinated Control Strategy of BESS and PMSG-WTG for Fast Frequency Response [PDF]
Applied Sciences, 2021 An increase in inverter-based resources (IBRs) can lower the inertia of a power system, which may adversely affect the power system by causing changes such as a frequency nadir reduction or an increased initial rate of change of frequency (RoCoF).

An Extreme Learning Machine-Based System Frequency Nadir Constraint Linearization Method [PDF]
, 2021 Large-scale integration of converter-based renewable energy sources (RESs) into the power system will lead to a higher risk of frequency nadir limit violation and even frequency instability after the large power disturbance. Therefore, it is essential to consider the frequency nadir constraint (FNC) in power system scheduling.

Multi-area power system frequency nadir prediction
2023 IEEE PES Innovative Smart Grid Technologies Europe (ISGT EUROPE), 2023 This paper presents a novel method for analyzing power system frequency response in multi-area power systems. Although single-area power system models are commonly used due to their simplicity, they do not always accurately represent the complex dynamics of multi-area systems.
