摘要:

本文考虑了在有色高斯噪声干扰下智能电网的状态估计和虚假数据注入检测问题。通过建模噪声为自回归过程,我们估计了电力传输网络的状态,并开发了广义似然比检验检测器用于检测虚假数据注入攻击。我们证明了传统方法在高斯噪声假设下的情况是所提出方法的特例,因此新方法更具普遍性。所提出的检测器还测试了基于独立成分分析(ICA)的不可观测虚假数据攻击方案,该方案利用了类似的样本观测假设。我们评估了所提出的状态估计器和攻击检测器在IEEE 30节点电力系统中的性能,并与传统基于高斯噪声的检测器进行了比较。所提方法在可观测和不可观测的虚假数据攻击中的优越性能表明了所提方法的有效性,并表明其在电力信号处理中的广泛应用。

英文摘要:

In this paper, we consider the problems of state estimation and false data injection detection in smart grid when the measurements are corrupted by colored Gaussian noise. By modeling the noise with the autoregressive process, we estimate the state of the power transmission networks and develop a generalized likelihood ratio test (GLRT) detector for the detection of false data injection attacks. We show that the conventional approach with the assumption of Gaussian noise is a special case of the proposed method, and thus the new approach has more applicability. {The proposed detector is also tested on an independent component analysis (ICA) based unobservable false data attack scheme that utilizes similar assumptions of sample observation.} We evaluate the performance of the proposed state estimator and attack detector on the IEEE 30-bus power system with comparison to conventional Gaussian noise based detector. The superior performance of {both observable and unobservable false data attacks} demonstrates the effectiveness of the proposed approach and indicates a wide application on the power signal processing.
