风力发电系统发电容量时间序列的混沌属性分析

CHAOS CHARACTERISTIC ANALYSIS ON THE TIME SERIES OF WIND POWER GENERATION CAPACITY

利用非线性动力学的分析方法对并网型风电机组的发电容量时间序列进行分析,以检验其是否存在混沌属性。分析表明,通过对低维非线性动力学建模,风电机组发电容量时间序列表现出了混沌特性,此结果为基于混沌时间序列的风力发电容量预测奠定了基础。

The time series of wind power generating capacity were examined by nonlinear dynamical methods, in order to identify chaos characteristic from its random-like waveform. The analysis of modeling with low dimensions nonlinear dynamics indicated that time series of wind power generation capacity have chaos characteristic, and wind power generating capacity can be predicted in short time.
