State space model building and validation by comparison with non-linear models and performing SSA

The level of penetration of renewables and power electronics in the grid is increasing, and in the future, it may even be possible to have a 100 % converter-based transmission system[1]. In such a future, methods for analyzing the stability of the grid with high penetration of power electronics and...

In such a future, methods for analyzing the stability of the grid with high penetration of power electronics and renewable energy sources are essential.
