摘要翻译：
传感器如相量测量单元（PMUs）被赋予GPS接收器普遍安装，提供实时的网格可见性。多个PMU可以协作地启用状态估计例程。然而，GPS欺骗攻击可以显著地改变PMU测量，误导网络运营商，并严重影响后续的纠正控制行动。利用一个新的测量模型，明确地解释了GPS欺骗攻击，提出了一个优化问题，以识别网络中最易受攻击的PMU。提出了一种贪婪算法来解决上述问题。此外，本文还提出了一种计算效率较高的交替最小化算法，用于联合状态估计和攻击重构。在IEEE基准网络上的数值试验验证了所提出的方法。

英文摘要：
Sensors such as phasor measurement units (PMUs) endowed with GPS receivers are ubiquitously installed providing real-time grid visibility. A number of PMUs can cooperatively enable state estimation routines. However, GPS spoofing attacks can notably alter the PMU measurements, mislead the network operator, and drastically impact subsequent corrective control actions. Leveraging a novel measurement model that explicitly accounts for the GPS spoofing attacks, this paper formulates an optimization problem to identify the most vulnerable PMUs in the network. A greedy algorithm is developed to solve the aforementioned problem. Furthermore, the paper develops a computationally efficient alternating minimization algorithm for joint state estimation and attack reconstruction. Numerical tests on IEEE benchmark networks validate the developed methods.
