Alternativa para minimizar el costo de la energía eléctrica en zonas francas de Colombia

minimizing the cost of electricity in commercial areas of colombia is one of the biggest needs of this economic sector covering the competitiveness of industrial parks that stimulates investment in this country. in this article, an optimization tool is described on the exploitation of a self- generation plant that together with the conventional connection to electrical networks is used as a source of energy to supply it to commercial areas. under these general conditions, the advantage of operational hypothetic conditions has been evaluated. as a computational tool to determine this model, we apply the so- called general system of algebra model- gams- with the support of matlab to facilitate incomes and data processing.
