Abstract: This seminar presents a technique to solve efficiently a Robust Security- Constrained Optimal Power Flow (R-SCOPF) problem. A bilevel max-min optimization model is proposed to find the worst contingencies while representing Alternating Current (AC) power flow equations and considering corrective actions. The objective is to minimize the total generation cost while satisfying operation and security constraints. The upper-level problem allows representing contingencies using binary variables. The lower-level problem represents the AC optimal power flow problem using a second-order cone relaxed formulation. Duality is then used to merge the upper- and lower-level problems into a single- level one. The resulting mixed-integer second-order conic problem can be efficiently solved. Two case studies are presented as applications of this technique.
