Spatially Correlated Wind Speed Modelling for Generation Adequacy Studies in the UK

Generation adequacy assessment is an essential tool in the analysis of the security and planning aspects of power systems. This, associated to the growth in wind power plants worldwide, has driven the need to better characterise the resource to support the integration of this technology into the power system. This paper introduces a time-series-based model of the wind speed for adequacy studies using the GB system (UK). The modelling methodology is described and simulation results presented using the Loss of Load Probability (LOLP) as the adequacy index shown against differing plant margin backgrounds.
