Abstract:
The Governments of the Republic of Ireland and Northern Ireland have committed to highly ambitious renewable energy targets for the 2020 Single Electricity Market (SEM) with accommodation of up to 40 % or 6 GW of renewables, mostly in the form of wind power. This aim requires appropriate flexible generators to support efficient and reliable future electricity market operation and utilisation of the maximum potential from wind power sources. Therefore the principal aim of this thesis is the investigation of the most appropriate flexible solutions for the 2020 SEM, in particular: peaking generators, energy storage, additional interconnection with neighbouring markets and new advanced CCGT power plants. These technologies are implemented through a series of policy and literature- supported future SEM models based on the current electricity market model PLEXOS and compared with each other in terms of technical benefits for the electricity market operation, economical advantages for the final consumer and investment viability. In order to achieve the core aim of this thesis, a comprehensive review of the current SEM, its generation profile, operation and trading arrangements, as well as future governments' goals and market development profile have been carried out. Thereafter, an appropriate methodology for the simulation of the SEM has been developed by using the Plexos software tool. Additional investigations of the GB market allowed an understanding of market misalignments to ensure efficient cross-border trading via interconnectors. Thus in exploring the potential for the future market harmonisation, a new methodology has been developed to represent the GB market in 2020 by a model constructed with the Plexos software. The final 2020 model was proved to be acceptable for the future modelling via an extensive validation and verification test. The modelling results suggest that the greatest benefits for the 2020 wind dominated SEM operation will occur through the use of Advanced CCGT power plants or Energy storage ,. systems. The additional interconnection option will become viable only under the government investment, although, even then, it would be sill less beneficial for the SEM in 2020 than Advanced CCGT or Energy Storage options. Peaking generators are the least advantageous among all other flexible generators.
