Article 5 in the series on impedance-based stability analysis
Over the first four articles in this series, we have built a complete conceptual toolkit for impedance-based stability analysis. Transfer functions (Article 2), the Nyquist crit...
Why Short-Circuit Ratio Is Quietly Failing Modern Power Systems
For nearly a century, one number told grid engineers almost everything they needed to know about whether a connection point could safely host new generation: the Short-Circuit Ratio. Calculate the short-circuit power available at the bus, d...

Article 4 in the series on impedance-based stability analysis
Last week we established the Nyquist stability criterion — the test that answers, from two impedance curves alone, whether a converter and a grid will oscillate together. That t...
When Regions of the Grid Swing Against Each Other
Most grid stability discussions today centre on frequency and voltage. The first article in this series covered voltage — how it is controlled, why it is eroding, and what happens when it breaks. This second article addresses a phenomenon t...
The Nyquist Stability Criterion
Article 3 in the series on impedance-based stability analysis
Last week’s article ended on a promise. We had established that the impedance of a grid and the impedance of a converter are each transfer functions — curves in the frequency do...
