PMU网络在近几十年来一直被用于监测智能电网的系统运行。这给电网带来了重大的网络风险，因为攻击者可以操纵PMU网络引入假阳性和假阴性观测误差。提出了一种考虑观测误差的PMU网络风险模型。理论和仿真研究表明，忽略观测误差会严重低估PMU的风险。研究了考虑观测误差时提高PMU安全水平的风险缓解策略。研究发现，当观测误差存在时，最优抑制策略可能不同。最后给出了数值算例。
The PMU network has been utilized to monitor the system operation of a smart grid in recent decades. This brings a significant cyber risk for the power grid as the attacker can manipulate the PMU network to introduce the false positive and false negative observation errors. A novel risk model is proposed for the PMU networks by considering the observation errors. It is discovered that ignoring the due observation errors can severely underestimate the PMU risks as shown by the theoretical and simulation studies. The risk mitigation strategies for improving the safety levels of PMUs with the observation errors are studied. It is found that the optimal mitigation strategy can be different when the observation errors are present. Numerical examples are presented for illustrations as well.
