本文研究了由不同Lé过程驱动的Ornstein-Uhlenbeck过程对配电网负荷建模的适用性。文中对估算所需参数的程序进行了深入的描述。将模拟过程的统计特性及其自相关性与现场测量数据的统计特性进行了比较，以验证所提出的方法的适用性。从微同步相量(μPMU‘s)获得的测量促进了这种随机模型的发展。来自这些设备的数据用于展示对波动率进行建模的必要性以及验证试图对所述波动率进行建模的模型。
This paper investigates the suitability of the Ornstein-Uhlenbeck process, driven by various Lévy processes, for load modeling at the distribution network level. An indepth description outlining the procedure for estimating the required parameters is given. Both the statistical properties of the simulated processes and its auto-correlation is compared to that of the field measured data to demonstrate the suitability of the proposed methodology. The development of such stochastic models is facilitated by measures obtained from micro-synchrophasors (μPMU's). The data from these devices serves to demonstrate the need to model the volatility along with validating a model attempting to model said volatility.
