Phasor measurement units (PMUs) used to monitor and the control of power systems are vulnerable to GPS spoofing attacks. A team of researchers in the US (Clemson University, UC Santa Barbara) proposes a distributed real-time wide-area oscillation estimation approach that is robust to GPS spoofing on PMUs and their associated phasor data concentrators. The approach checks update consistency with histories and across distributed nodes and can tolerate up to one third of compromised nodes. It can be implemented in a completely decentralized architecture and in a completely asynchronous way. They have confirmed the effectiveness of the approach by numerical simulations of the IEEE 68-bus power system models… read more. TECHNICAL ARTICLE
