The GPS is vulnerable to GPS spoofing attack (GSA), which leads to disorder in time and position results of the GPS receiver. In power grids, phasor measurement units (PMUs) use GPS to build time-tagged measurements, so they are susceptible to this attack. As a result of this attack, sampling time and phase angle of the PMU measurements change. In this paper, a neural network GPS spoofing detection (NNGSD) with employing PMU data from the dynamic power system is presented to detect GSAs. Numerical results in different conditions show the real-time performance of the proposed detection method

“…Since GPS systems use wireless communication, receivers are vulnerable to cyberattacks, including GPS spoofing attacks. The spoofer generates false GPS signals and broadcasts them [1]. The adjacent GPS receiver tracks transmitted fake signals, so false time tags are received [2].…”

The modern power grid is being used under operating conditions of increasing stress, giving rise to grid stability issues. One of these stability issues is the phenomenon of inter-area oscillations. Simulations have demonstrated the advantages of Wide-area Measurement Signals (WAMS)-based Oscillation Damping Controls in achieving improved electromechanical mode damping compared to traditional, local signal-based Power System Stabilizers (PSS). This work takes an existing Phasor-based oscillation damping (POD) algorithm and uses it to implement a proof-of-concept, wide-area, real-time controller on National Instruments hardware. The developed prototype is tested in a real-time Hardware-in-theloop setup (RT-HIL) using OPAL-RT's eMEGASIM real-time simulation platform and synchrophasor data from actual Phasor Measurement Units (PMUs). The prototype and experiments provide insight into the feasibility and real-world limitations of wide-area controls. Further, it is demonstrated how the proposed control architecture has applications independent of the controlled power system device. Challenges faced, the solutions implemented together with the present prototype's limitations are also discussed.

“…GPS spoofing exploits publicly available civilian GPS signals using air or cable to produce signals that initially align with the original, but slowly start increasing the power to drown the authentic signal and thereby compromising the receiver [54,127]. By introducing measurement errors in the time synchronization, the attacks induce changes in data consistency and plausibility which can be used as markers to identify the likelihood of the attack [128][129][130].…”

Synchrophasor devices guarantee situation awareness for real-time monitoring and operational visibility of the smart grid. With their widespread implementation, significant challenges have emerged, especially in communication, data quality and cybersecurity. The existing literature treats these challenges as separate problems, when in reality, they have a complex interplay. This paper conducts a comprehensive review of quality and cybersecurity challenges for synchrophasors, and identifies the interdependencies between them. It also summarizes different methods used to evaluate the dependency and surveys how quality checking methods can be used to detect potential cyberattacks. In doing so, this paper serves as a starting point for researchers entering the fields of synchrophasor data analytics and security.
