New grid connection rules in Romania
The Romanian Energy Regulatory Authority (ANRE) has adopted several changes to grid connection processes, including the
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.
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.
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).
However, the Romanian power system is synchronously interconnected with the neighboring system and probably the analysis about the weight of invertor based generation would become regional, not only national. A large share of the solar PV capacities will be non-utility, pertaining to prosumers.
