  It is a major task to develop effective strategies for defending the power
system against deliberate attacks. It is critical to comprehensively consider
the human-related and environmental risks and uncertainties, which is missing
in existing literature. This paper considers the load demand uncertainties and
wind generation uncertainties in addition to the interactive attacker/defender
behaviors. Specifically, a defender-attacker-nature-operator model is proposed,
which incorporates the attack/defense interaction, the corrective re-dispatch
of the operator, the coordination between the attack strategy and the
stochastic nature of load demands and wind generations. The
Column-and-Constraint Generation (C&CG) algorithm is adopted for solving the
proposed model by decomposing the proposed model into a master problem and a
sub-problem. Simulations are performed using MATLAB and CPLEX on a modified
IEEE RTS79 system. The simulation results verify the validity of the proposed
model.
