“…Provided that the wind is not calm everywhere across the grid, power will be produced somewhere, with the benefits to supply reliability increasing as the correlations of wind speed between multiple wind farms decrease (Kempton et al 2010). Those that have done so have focused on examining synoptic weather patterns or maps over selected periods of time to act as case studies (e.g., Oswald et al 2008;Kempton et al 2010;Leahy and Foley 2012), as opposed to giving consideration to the entire distribution of wind speed or power generation. However, few studies have attempted to understand causal mechanisms of the benefits of interconnecting wind farms from a climatological or meteorological perspective.…”

Even in locations endowed with excellent wind resources, the intermittent nature of wind is perceived as a barrier to reliable generation. However, recent studies have demonstrated that electrically interconnecting wind farms in a meteorologically oriented network can reduce supply variability and the observed frequency of zero-generation conditions. In this study a 5-yr synthetic dataset of 15 wind farms is utilized to investigate the benefits to supply reliability from wind farm interconnection in New Zealand. An examination is carried out primarily through a synoptic climatology framework, hypothesizing that benefits to reliability are primarily related to the degree to which wind farms are influenced differently by the synoptic-scale circulation. Using a weather-typing approach and composite analysis, regionality is observed in the linkages between synoptic-scale circulation and wind resources, particularly between wind farms located in the far northern and far southern regions of the country. Subsequently, and as compared with all other possible combinations, supply reliability is observed to be optimized in a network that includes wind farms connected between far northern and far southern regions, under which the frequency of hours with zero generation is almost eliminated. It is likely that the frequency of hours with zero generation could be further reduced on the basis of a more extensive meteorologically based selection of wind data from a greater number of locations. It is suggested that these findings should be taken into consideration in future planning and site selection of wind farm projects in New Zealand. * Current affiliation: Climate

“…On daily to weekly timescales GB wind power capacity has been related to synoptic scale (approximately 1000 km) weather events termed regimes, with zonal (west-east) regimes resulting in highest aggregate wind power generation, and blocked regimes resulting in lowest aggregate wind power generation [14,15]. There is general consensus in the literature that GB peak demand is associated with an area of high pressure in the vicinity of GB, consistent with low temperatures over GB [14,[16][17][18]. These previous studies of climate-energy interactions are, however, typically limited in two key respects.…”

The increasing use of intermittent renewable generation (such as wind) is increasing the exposure of national power systems to meteorological variability. This study identifies how the integration of wind power in one particular country (Great Britain, GB) is affecting the overall sensitivity of the power system to weather using three key metrics: total annual energy requirement, peak residual load (from sources other than wind) and wind power curtailment.The present-day level of wind power capacity (approximately 15 GW) is shown to have already changed the power system's overall sensitivity to weather in terms of the total annual energy requirement, from a temperature-to a wind-dominated regime (which occurred with 6GW of installed wind power capacity). Peak residual load from sources other than wind also shows a similar shift. The associated changes in the synoptic-and large-scale meteorological drivers associated with each metric are identified and discussed. In a period where power systems are changing rapidly, it is therefore argued that past experience of the weather impacts on the GB power system may not be a good guide for the impact on the present or near-future power system.

“…Large scale weather patterns have been shown to influence electricity demand and renewable supply over Northern Europe, including the North Atlantic Oscillation [12,14] (NAO, a measure of the large scale north-south atmospheric pressure difference), and high pressure systems. The influence of high pressure on wind power supply and demand is however under debate [10,16,17].…”
