Optimal Configuration of PMU Based on False Data Injection

摘要

At present, the injection of false data (FDI) in power system network brings a direct challenge to state estimation and reduces the reliability of the system. The data collected by WAMS system is of high frequency and accuracy, which can effectively prevent FDI attacks. This paper focuses on the problem of PMU optimization configuration considering false data injection. On the premise of ensuring the overall observability of the system and taking the zero injection node into account, the effect of false data injection on the power grid is effectively reduced through the optimized configuration of PMU, and the accuracy of state estimation data is improved to the maximum extent. Taking IEEE14 IEEE30 and IEEE57 standard nodes as examples, the data accuracy was improved to the maximum extent with the minimum number of PMU, and the feasibility of the method was verified.
