Abstract :
[en] This paper focuses on improving the solution techniques for the AC SCOPF problem of
active power dispatch by using the DC SCOPF approximation within the SCOPF algorithm.
Our approach brings two benefits compared to benchmark SCOPF algorithms:
it speeds-up the solution of an iterative AC SCOPF algorithm thanks to
a more efficient identification of binding contingencies, and allows
improving the objective by an appropriate choice of a limited number
of corrective actions for each contingency.
The proposed approach is illustrated on 5 test systems of 60, 118, 300,
1203, and 2746 buses.
