In recent years there has been an increasing deployment of wind-powered generation technology, i.e. wind farms, on electricity networks across Europe. As this deployment increases it is important to understand how climate variability will affect both windpowered and non-renewable power generation. This study extends the literature by assessing the impact of NAO, via wind-power generation, on carbon dioxide emissions from the wider electricity system. A Monte Carlo approach is used to model NAO phases, generate hourly wind speed timeseries data, electricity demand and fuel input data. A unit commitment, least-cost economic dispatch model is used to simulate an entire electricity system, modelled on the all-island Irish electricity system. Our results confirm that the NAO has a significant impact on monthly mean wind speeds, wind power output, and carbon dioxide emissions from the entire electricity system. The impact of NAO on emissions obviously depends on the level of wind penetration within an electricity system but our results indicate that emissions intensity within the Irish electricity system could vary by as much as 10% depending on the NAO phase within the next few years. The emissions intensity of the electricity system will vary with the NAO phase. Terms of use: Documents in

Energy Internet: The business perspective

“…The increasingly serious resource and environment problems have driven people to continue to think about the reform of energy systems [1][2][3][4][5]. Information and communication technologies (ICTs), especially the emerging information technologies such as cloud computing, Internet of Things, big data analytics and mobile intelligence, are reshaping the landscape of many traditional industries and the daily life style of the general public [6][7][8][9][10].…”

A 34-year simulation of wind generation potential for Ireland and the impact of large-scale atmospheric pressure patterns

“…Additionally, such models can help to identify and analyse longerterm and wider-ranging climatic patterns influencing wind generation. For example, this approach would offer an alternative to the statistical wind data generation techniques used to examine the effects of the NAO in Brayshaw et al (2011), Curtis et al (2016) and Ely et al (2013).…”

Highly resolved optimal renewable allocation planning in power systems under consideration of dynamic grid topology

“…Overall, the above results show that the uncertain demand development, in the long run, creates enormous challenges for policy and planning in terms of compliance with RES-E policy targets defined as % shares of the overall electricity demand. This challenge has also been discussed by [33] in the context of climate variability. Moreover, our results show that, unsurprisingly, wind onshore proves to be the dominant technology across all scenarios.…”
