This paper proposes a new method of optimal FACTS devices allocation to be used in the preventive/corrective control (PCC) against voltage collapse. The new formulation takes into consideration the transition states that the power system may expose such as normal state and contingency states. For the severe contingencies that drive the system to voltage collapse, the corrective control is initiated by means of fast response of FACTS and load shedding to restore the system with small positive load margin, then the preventive control is carried out using all the fast and slow devices ensuring security margin and voltage feasibility. For this control strategy, FACTS allocation are determined based on the minimum cost for the installations and the operations.. The problem is formulated as a mixed integer nonlinear programming problem, which is solved using hybrid genetic algorithm/successive liner programming (GA/SLP) approach. The IEEE 57 bus system is tested to demonstrate the effectiveness of the proposed method.
