National Grid ESO And Reactive Technologies Launch Flagship Inertia System To Measure Grid Stability

The title of this post is the same as that of this article on Current News.

The first three paragraphs explain the project.

National Grid ESO and Reactive Technologies’ flagship grid stability measurement service has launched today, following the construction of the world’s largest continuously operating grid-scale ultracapacitor.

Using Reactive’s GridMetrix technology, the new services will provide instantaneous data to the grid operator, allowing for more efficient management than relying on estimates.

The ultracapacitor – constructed by Spanish technology group Ingeteam – sends pulses through the grid, which act like underwater sound waves used in sonar. These pulses will enable the ESO to measure power system stability.

As a Control and Electrical Engineer, I can just about get my brain around what is happening, but I do feel the explanation could be better.

  • There is no mention of the size of the capacitor.
  • Capacitors are often used to calm voltages in electrical circuits.
  • How does the capacitor send pulses through the grid? It must be some other piece of kit linked to the capacitor.

In the end though, I don’t care, if it works.
