As Europe’s power system evolves, maintaining grid stability in an increasingly inverter-based system is becoming a key priority. ENTSO-E has published a new report that identifies how to better detect and analyse forced oscillations – unwanted fluctuations that can affect system stability in the power grid.
The report provides clarification and non-binding guidance to the requirements set out in the proposed amendments to the Network Code on Requirements for Grid Connection of Generators (NC RfG 2.0). These proposed amendments are now taken up by the European Commission for formal adoption.
The report was developed in collaboration with WindEurope through a joint technical group of experts, reflecting two years of close cooperation. It proposes non-binding guidance based on case studies from several wind farms. Even though it focuses solely on wind turbines, the RfG 2.0 requirements will apply to other types of non-synchronous power generation and electricity storage modules as well.
The report will act as a basis for a future implementation guidance document, to be drafted by ENTSO-E, which will support system operators with the national implementation of forced oscillations limitation requirements once the NC RfG 2.0 enters into force.
