一种电力系统量测噪声自适应抗差状态估计方法
An Adaptive Robust State Estimation Approach for Measurement Noise
摘要
Abstract
To overcome the limitations of traditional state estimation in dealing with noise measurement,a general model of robust state estimation (RSE) is proposed based on maximum correntropy criterion (MCC),which is able to unify several existing RSE models in theory and derive new RSE models.An adaptive robust state estimator(ARSE)for measuring noise is proposed,which makes it possible to obtain the distribution type of noise measurement through statistical learning.Then the corresponding optimal RSE model is selected online to adapt to the variation of noise measuring distribution type.ARSE is able to yield optimal estimation results closer to the true values of the state variables for common noise measuring distribution types.Simulation results show the effectiveness of the proposed ARSE.关键词
