Despacho económico de generación termoeléctrica usando métodos de sensibilidad AC.

Abstract

Electricity generation is linked to technical factors characteristic of each energy transformation process and also the economic factors that it generates, the less expensive it is to produce electricity, this can be generated to a greater amount satisfying more and more a greater number of users, that is, covering the power demand of the system with reduced costs. This becomes the great task to be done for operators of the electrical systems, which is known as the Economic Power Dispatch. This paper presents two methods of resolution of the economic dispatch, each of these has its own formulation to consider the power losses that exist in the electrical transmission in the electric networks. The implemented methods are iterative Lambda and the Jacobian, which allow determine the penalty applied to the generators after the losses in the power system have increased; in both cases it is necessary first to know the solution of the load flow of the system. The results obtained for a test system indicate that the iterative Lambda method solves a lower operating cost at a lower number of iterations, which represents economic and computational savings of calculation.
