Planeación óptima de flujos de potencia reactiva en sistemas eléctricos de transmisión basado en optimización no lineal entera mixta

Abstract

At present, the optimal planning of reactive power in the electrical systems fulfills one of the most important functions for the control, having to adjust the stability margin of the electrical system. The methodology of tension control and redistribution of the flows in the transmission lines has as main objective to achieve a global improvement in the security and stability of the system. To achieve this, use three fundamental aspects: request a good quality of service, establish voltage levels and reactive power reserves, and perform efficient controls from an economic point of view. In the planning of reactive power in the electrical transmission systems, the implementation of compensating equipment is necessary, thus achieving an improvement in the range of nodal voltage and the reactive component. The present work shows a methodology that allows reducing the costs of implementing compensating equipment, finding the optimal location in the system, improving its stability at the lowest cost.
