This paper presents a model based on a Optimal Reactive Power Flow (ORPF) to allocation of Static VAr Compensator (SVC) in the power transmission network. The SVC was modeled as a variable susceptance and inserted into Ybus matrix. For discretization of the devices to be allocated in the system were used binary variables associated to SVC susceptance. A multiobjective function formed by two parts, active power losses and voltage deviation, was used in the ORPF formulation. In each one of parts was associated a parameter that allows to give more or less weight to each part. Due to the problem characteristics, Mixed Integer Nonlinear Programming (MINLP), was used a Branch & Bound (B&B) algorithm associated with the ORPF. The model was tested in the IEEE 118 bus system. The results show that the modeling and the technique of solution used are appropriate for SVCs allocation and powersystem analysis
