The importance of grid connection studies increases around the world. TSOs focus more on the grid impact of new generation units as the energy transition moves forward. Adding more converter-based units changes the power system dynamics fundamentally, e.g. higher frequency gradients. That’s also why TSOs require rate-of-change-of-frequency (RoCoF) analyses before the approval of prospective units….
The importance of grid connection studies increases around the world. TSOs focus more on the grid impact of new generation units as the energy transition moves forward. Adding more converter-based units changes the power system dynamics fundamentally. That’s also why most TSOs require a fault-ride-through (FRT) analysis of prospective units before approval. Similarly important is…
In this post, I present a simple, but effective way of inter-area oscillation analysis with phaser measurement unit (PMU) data. I simply run a Fourier analysis, more specifically a Fast Fourier Transform (FFT), on the measured power system frequency to identify the oscillation modes. So, if you have access to PMU data, you can use…
This is a follow-up to my post about Transient Stability Analysis by Evaluation of the Critical Clearing Time with Python in DIgSILENT PowerFactory. While the mentioned post describes the evaluation of transient stability, this post addresses the improvement of transient stability by re-dispatching of synchronous generators. The goal of the re-dispatching is to guarantee a…
Most power system engineers have faced some kind of stability-related questions in their careers. In my case, I have worked quite a bit on transient stability related matters during my PhD (the publications are available on Google Scholar). That is why I decided to write this article about transient stability analysis by evaluation of the…
