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…
Thanks to one of my former PhD supervisors Mattia Marinelli, I can provide a pitch-controlled variable speed doubly-fed induction generator (DFIG) wind turbine model in DIgSILENT PowerFactory. Mattia developed and implemented the comprehensive model to study and teach wind integration in the power system. In this post, I present the general concepts of the implemented…
