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.

Hydrogen modelling and converter control

Hydrogen comes out as a promising energy vector due to its versatility, clean combustion, and possibility to act as an energy storage resource. Electrolysis is a process that consists of using electricity to produce hydrogen from water. This kind of process requires the installation of a power converter, usually based on regular thyristors or IGBTs, to offer controllability. eRoots specializes on developing the models and control schemes for such devices. :

  • Electrolyser modelling
  • Grid-following and grid-forming control schemes
  • Control tuning based on the process requirement
  • Creation of STATCOM models
  • Addition of DC/DC converters
