Renewables integration, flexibility measures and operational tools for the Ireland and Northern Ireland power system
76 REE Ndeg5/2016 ENJEUX D'UN DEVELOPPEMENT MASSIF DES EnR DANS LE SYSTEME ELECTRIQUE EUROPEEN DU FUTUR DOSSIER 1 Introduction The Ireland and Northern Ireland power system is pursuing ambitious renewable energy (mainly wind gene ration) targets for 2020. A range of system wide initiatives are being deve loped as part of the DS3 (Delivering a Secure, Sustainable Electricity System) programme, and, in particular, a bes poke suite of ancillary services incenti vising fast frequency response, dynamic reactive power and ramping margin, and other, (future) system needs. With ap proximately 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 opera tors (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 solu tions and strategies which have been proposed, and ongoing challenges for the future. Island of Ireland power syst
