Query: Analysis of IoT-Based Load Altering Attacks Against Power Grids Using
  the Theory of Second-Order Dynamical Systems   Recent research has shown that large-scale Internet of Things (IoT)-based
load altering attacks can have a serious impact on power grid operations such
as causing unsafe frequency excursions and destabilizing the grid's control
loops. In this work, we present an analytical framework to investigate the
impact of IoT-based static/dynamic load altering attacks (S/DLAAs) on the power
grid's dynamic response. Existing work on this topic has mainly relied on
numerical simulations and, to date, there is no analytical framework to
identify the victim nodes from which that attacker can launch the most
impactful attacks. To address these shortcomings, we use results from
second-order dynamical systems to analyze the power grid frequency control loop
under S/DLAAs. We use parametric sensitivity of the system's eigensolutions to
identify victim nodes that correspond to the least-effort destabilizing DLAAs.
Further, to analyze the SLAAs, we present closed-form expression for the
system's frequency response in terms of the attacker's inputs, helping us
characterize the minimum load change required to cause unsafe frequency
excursions. Using these results, we formulate the defense against S/DLAAs as a
linear programming problem in which we determine the minimum amount of load
that needs to be secured at the victim nodes to ensure system safety/stability.
Extensive simulations conducted using benchmark IEEE-bus systems validate the
accuracy and efficacy of our approach.
