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.
