Despacho económico en mercados desregularizados considerando pérdidas en el sistema eléctrico de potencia minimizando costos operativos

Abstract

The electrical power systems SEP establish a structure of energy and commercial development, for this reason the technical coordination and economic control of their processes is essential. Currently, the deregulated electricity market handles the transactions established between the participants. The problem in the SEP is the allocation of units to supply the demand taking into account the losses in the transmission system, this implies operating costs and alterations in the quality of the energy that is supplied to the loads in each bus of the system. In the present research work, the solution to the economic dispatch is proposed by means of an Optimum Power Flow in AC applying generation and transmission restrictions for both active and reactive power. The proposed method is developed in a mathematical modeling language. This process is implemented in the IEEE 14 and 39 bus standard models. The generation units show optimal behavior within the established parameters. The proposed OPF AC model minimizes operating costs even in the presence of transmission losses, the values of the voltages and angles on each bus remain at an adequate level.
