AB - Smoothing of generation variability, i.e. reduction of variance in the aggregate generation is crucialfor grid integration of large-scale wind power plants. Prior studies of smoothing have focused ongeographical smoothing, based on distance. In contrast, we propose a novel concept ‘diurnalsmoothing’ that depends on spatial variations in the timing of seasonal-mean diurnal cycle peak.Considering the case of India, which experiences a strong diurnal cycle of wind-speed, we showhow spatial heterogeneity in the wind diurnal cycle can be exploited to smooth wind powervariability over and above geographical smoothing. For any given separation distance betweensites, the hourly wind speed correlation is highly variable. Difference in timing of the diurnal cyclepeak is an important factor for explaining this variability and we define smoothing from differentlytimed seasonal-mean diurnal cycle as ‘diurnal smoothing’. We show that apart from separationdistance, the diurnal cycle is crucial for correlation among sites separated by 200 km or more withstrong diurnal cycles (amplitude more than approximately 0.5 m s−1). Thus, diurnal smoothing isa vital factor in the aggregation of large wind power plants, and grid integration is benefited byconsidering (in addition to distance) new wind plant sites with largely separated diurnal cycles,especially those differing by roughly 12 h. Such diurnal smoothing is relevant for regions across theworld with strong wind speed diurnal cycles. Ultimately grid integration depends on variations intotal wind and solar generation and demand. Hence, their combined effects must be studied.
