This paper presents a method for Parameterized Contingency Constrained Optimal Power Flow (PCCOPF) whose formulation can discriminate unpreventable contingencies, determine the existence of feasible solutions for post contingencies and analyze the feasible solution for the contingencies in terms of static sense. The proposed formulation is based on parameterized contingency constraints in which each contingency parameter represents the achievement ratio of each selected contingency. In the formulation, not only parameterized contingency constraints are given by a set of equality constraints which is modified power flow equations, but also the objective is maximization of the'sum of the achievement ratios of selected contingencies. Since contingency parameters are treated as decision variables in the proposed method, the information on unsolvability with respect to each contingency can be efficiently obtained. The feasibility and effectiveness of the proposed method are demonstrated on test problems with 4-bus and 71-bus systems.
