Optimal power flow (OPF) and optimal location of FACTS devices are very important tools in planning and operation of power system. In multi-objective OPF due to being poor collaboration among design objectives and poor resolution of design conflicts, relations are complex.To handle these problem, a fuzzy interactive multi-objective optimization model is developed based on Pareto solutions while the metric function and some additional constraints are added to ensure the collaboration among

It is able to interact with decision maker (DM) against all OPF method, and DM can direct process to side that it meet his priority for scheduling power systems. In this paper OPF is formulated as a nonlinear optimization problem with both equality and inequality constraints. The proposed objective functions are: minimization of total fuel cost, minimization of active power losses Numerical examples are presented in order to show efficiency of proposed technique through 118-bus IEEE test system using MATLAB and Generalized Algebraic Modeling of System (GAMS) softwares.
