Abstract
Autorii discuta impactul modificarii ponderilor raportului dintre tehnologiilor de producere a energiei electrice in Sistemul Energetic National pe fundalul tranzitiei energetice. Generatoarele sincrone cu mase inertiale mari in miscare se retrag din exploatare, in timp ce tehnologiile bazate pe generatoare asincrone sau conectate la retea prin electronica de mare putere (invertoare) isi cresc in permanenta ponderea in structura momentana de producere. Capabilitatile de “grid forming” ale acestor noi generatoare devin critice pentru stabilitatea viitoare a sistemului energetic national. Articolul prezinta cateva concluzii din sistemele electroenergetice in care dezbaterea este mai avansata si contine cateva recomandari pentru sistemul electroenergetic romanesc
Authors discuss the impact of the shift in weights of power generation technologies in the Romanian National Power System on the background of the energy transition. Synchronous generators based on high inertia rotating machines withdraw from operation, while asynchronous generators and inverter based technologies acquire an ever-increasing share. Grid forming capabilities of such new generators (traditionally grid following technologies) become critical for the future stability of the power system. The article presents several conclusions from power systems where the debate is more advanced and draws some recommendations of the Romanian power system.
