论文摘要
建模风速的间歇性在许多领域（包括风力发电和分布）上具有很大的相关性。大多数可用的建模技术都假设风中的时间波动在本质上是随机的，而潜在的动力学最好通过统计方法或概率分布来描述。混乱理论的出现改变了对动态系统不规则波动的看法，它表明，随机的波动也可能来自确定性的混乱系统。 In this paper, we have analysed the deterministic nature of apparent random fluctuations seen in the daily average wind speed with the help of nonlinear time series analysis tools utilising wind speed data measured at nine typical locations over the Indian subcontinent from 2005 to 2015. The values of significant chaotic quantifiers obtained from the analysis clearly show the deterministic, low-dimensional and chaotic nature of wind speed dynamics in all these locations.
Modelling the intermittency of wind speed has got significant relevance on many fields, including wind power generation and distribution. Most of the available modelling techniques assume the temporal fluctuations in the wind is stochastic in nature and the underlying dynamics is best described by statistical methods or the probabilistic distribution. The advent of chaos theory have changed the perception about irregular fluctuations of dynamic systems and it has demonstrated that random-like fluctuations can also arise from deterministic chaotic systems. In this paper, we have analysed the deterministic nature of apparent random fluctuations seen in the daily average wind speed with the help of nonlinear time series analysis tools utilising wind speed data measured at nine typical locations over the Indian subcontinent from 2005 to 2015. The values of significant chaotic quantifiers obtained from the analysis clearly show the deterministic, low-dimensional and chaotic nature of wind speed dynamics in all these locations.
