Developing a taxonomy of cyber attacks in WAMS

Power grids are undergoing their largest technological transformation since their invention. They are adopting technologies like Phasor Measurement Units (PMU) to obtain real- time measurements of the system and report them to the control center for contingency analysis. These additional technologies may enhance reliability by providing a better real-time view of the system, but may be susceptible to cyber attacks. In this survey, we examine the cyber security aspects of Phasor measurement devices in a smart grid, and develop a taxonomy of attacks to be used in the evaluation and analysis of smart grid technologies. We present a taxonomy of attacks and attacker capabilities.
