Summary
This paper focuses on the impact and mitigation of extreme weather events, specifically wind ramps, solar ramps, windstorms as well as wind and solar droughts on the All-Island power system (AIPS) of Ireland and Northern Ireland.
Read more Read lessIt is well-known that rapid changes in the availability of wind and solar energy create fluctuations in generation affecting frequency and voltage quality, which require increased reserve capacity and faster response from system service providers. In this context, this paper provides a detailed overview of the ramping margin tool and ramping margin products used by the transmission system operators (TSOs) of Ireland and Northern Ireland, namely EirGrid and
SONI, respectively, to deal with such situations.
The paper will also discuss the impact that Storm Éowyn, one of the most severe in recent years, had on the operation of the AIPS. In particular, the planning and preparation for the storm, the impact on the transmission and distribution systems of Ireland, as well as observation and lessons learned, will be highlighted and discussed.
Finally, the paper will analyse the effect of wind and solar droughts based on 2025 and 2030
AIPS scenarios. Mitigation measures will be discussed to reduce their impact on the operation of the power system.
