  Driven by the necessity to combat climate change, Electric Vehicles (EV) are
being deployed to take advantage of their ability in reducing emissions
generated by the transportation sector. This deployment has left the power grid
vulnerable to attacks through the EV infrastructure. This paper is written from
an attacker\'s perspective and proposes a dynamic load altering strategy
through manipulating EV charging to destabilize the grid. The attack is
formulated based on feedback control theory, i.e., designing an attack based on
Linear Matrix Inequalities (LMIs). After the stability metric and controller
design have been established, we demonstrate our attack method against the
Kundur 2 area grid. The attack scenario includes a cap of 200 MW EV load
controlled by the attacker. However, the results show that even with this
limitation, the attacker would be successful in pushing the grid toward
instability and blackout.
