Georgia Pierrou, Xiaozhe Wang

摘要:

本文提出了一种新的纯测量为基础的方法,估计动态负荷参数在近实时随机负荷波动时存在。通过利用回归定理的Ornstein-Uhlenbeck过程,所提出的方法可以提供高度准确的估计,而不需要任何信息的电力系统模型。此外,利用递归,在线算法开发的动态负载参数估计在近实时。IEEE 39节点系统的仿真研究表明,无模型方法的准确性,其对测量噪声的鲁棒性,以及其令人满意的性能,在跟踪负载参数的实时变化。

英文摘要:

This paper proposes a novel purely measurement-based method for estimating dynamic load parameters in near real-time when stochastic load fluctuations are present. By leveraging on the regression theorem for the Ornstein-Uhlenbeck process, the proposed method can provide highly accurate estimation without requiring any information about the power system model. Furthermore, by exploiting recursion, an online algorithm is developed to estimate the dynamic load parameters in near real-time. Simulation studies on the IEEE 39-Bus system demonstrate the accuracy of the model-free method, its robustness against measurement noise, as well as its satisfactory performance in tracking real-time changes of the load parameters.
