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.
ANRE has also made several immediate changes to Romania’s grid connection processes, including new rules for financial guarantee. Previously required before concluding a connection, the guarantee is now a prerequisite for issuing any new grid connection permit above 1 MW and amounts to 5% of the connection tariff.
Romania should also be prepared for the adoption of rules related to grid forming capabilities of Electric Vehicles (EV) and for performances of the charging stations to serve such EVs (V1G – just absorption from the network, V2G – bidirectional relationship with the grid).
This dependency leads to fluctuations in power output and potential grid instability. Grid-connected inverters (GCIs) have emerged as a critical technology addressing these challenges. GCIs convert variable direct current (DC) power from renewable sources into alternating current (AC) power suitable for grid consumption .
