Renewables integration, flexibility measures and operational tools for the Ireland and Northern Ireland power system

摘要

The Ireland and Northern Ireland power system is pursuing ambitious renewable energy (mainly wind generation) targets for 2020. A range of system-wide initiatives are being developed as part of the DS3 (Delivering a Secure, Sustainable Electricity System) Programme, and, in particular, a bespoke suite of ancillary services incentivising fast frequency response, dynamic reactive power and ramping margin, and other, (future) system needs. With approximately half of the wind generation connected at distribution level, network development at both distribution and transmission levels is a key challenge for both the transmission system Operators (TSO) and distribution system Operators (DSO): a wide range of technical options are being examined, including undergrounding, HVDC connection and series compensation, supported by a public and stakeholder engagement Programme. The experience gained is highlighted, while also indicating solutions and strategies which have been proposed, and ongoing challenges for the future.
