Stability and dynamic analysis of modern Power Systems

eRoots Analytics has a solid track record with dynamic analysis of modern power systems employing state-of-the-art tools and simulations.

Renewable generation, FACTS or HVDC systems are different instances of the gradual introduction of power electronics components into the electrical grid. The increasing prevalence of such power electronics components are introducing new dynamic and stability phenomena into the Power Network, which must be analysed with the specific know-how that only eRoots Analytics can offer.

In particular, eRoots provides solutions that include:

  • Development of dynamic electrical grid models with the most common software packages

  • Small-signal analysis based on eigenvalues and participation factors to identify interactions and instabilities

  • Transient stability analysis based on EMT and RMS dynamic models
