Despacho óptimo de potencia reactiva basado en programación no lineal entera mixta y restricciones de cargabilidad de líneas de transmisión

Abstract

The optimal reactive power dispatch in electrical power systems becomes essential, since it allows the electrical system to operate in an optimal and stable way, by finding the most appropriate allocation of reactive power for both generators and compensation elements. However, as reactive power dispatches are optimized, generation costs are increasing, so it is necessary to guarantee a multi-objective optimization that allows improving the technical and economic characteristics of the electrical systems. Thus, at the present work, a multi-objective optimization algorithm is developed and implemented in the GAMS software, subject to several operational restrictions that keep the electrical system stable, guaranteeing an optimal reactive power dispatch without greatly increasing generation costs. The proposed algorithm will be evaluated and validated by simulation in Power Factory Digsilent software on the IEEE 14-, and 30- bus test system respectively.
