[en] This paper deals with day-ahead static security
assessment with respect to a postulated set of contingencies while
taking into account uncertainties about the next day system
conditions. We propose a heuristic approach to compute the
worst-case under operation uncertainty for a contingency with
respect to overloads. We formulate this problem as a non-convex
nonlinear bilevel program that we solve approximately by a
heuristic approach which relies on the solution of successive optimal
power flow (OPF) and security-constrained optimal power
flow (SCOPF) problems of a special type. The method aims at
revealing those combinations of uncertainties and contingencies
for which the best combination of preventive and corrective
actions would not suffice to ensure security. Extensive numerical
results on a small, a medium, and a very large system prove the
interest of the approach.
