Abstract
Although the advancement of cyber technologies in sensing, communication and smart measurement devices significantly enhanced power system security and reliability, its dependency on data communications makes it vulnerable to cyber-attacks. Coordinated false data injection (FDI) attacks manipulate power system measurements in a way that emulate the real behaviour of the system and remain unobservable, which misleads the state estimation process, and may result in power outages and even system blackouts. In this paper a robust dynamic state estimation (DSE) algorithm is proposed and implemented on the massively parallel architecture of graphic processing unit (GPU). Numerical simulation on IEEE-118 bus system demonstrate the efficiency and accuracy of the proposed mechanism.
