Detecting cyberattacks in a smart grid
Smart cities, by definition, run on intense digital communications between its assets. Besides its benefits, this makes smart cities prone to cyberattacks. As reinforcement learning is finding its way into cybersecurity, in this section, we describe how it can be applied to detecting attacks on a smart power grid infrastructure. Throughout the chapter, we follow the model proposed in (Kurt et al. 2019), while leaving the details to the paper.
Let's start with describing the power grid environment.
The problem of early detection of cyberattacks in a power grid
An electricity power grid consists of nodes, called buses, which correspond to generation, demand, or power line intersection points. Grid authorities collect measurements from these buses to make certain decisions such as brining in additional power generation units. To this end, a critical quantity measured is the phase angle at each bus (except the reference bus), which makes...
