This article presents the mathematical formulation of the active and reactive power generation pre-dispatch problem, whose objective function is the minimization of thermal plant costs and transmission losses. Bus voltages are represented in rectangular coordinates, transmission limits are imposed through linearized constraints and the optimization problem is solved by the Primal Dual Interior Point Method. The efficiency of the formulation is analyzed in a 5 buses example and an equivalent of the Paraná system composed of 291 buses.
