Minimización de pérdidas en sistemas de transmisión HVDC multi-terminal usando la técnica de optimización MVMO

Abstract

The increasing insertion of mainly renewable generation to interconnected power systems makes it necessary for HVDC transmission systems to be considered as a possibility of transporting electrical energy. These systems have a more complicated operation in relation to traditional AC systems; but on the other hand it has better voltage and power control. Thus, in this work the minimization of losses is performed in an HVDC transmission system, taking as control element the voltages of the converting stations of a DC network. For this optimization the MVMO method (Optimization by Medium Variance Mapping) is used, and the test HVDC network is called CIGRE B4 DC. Both the test system and the optimization method are implemented in the DIgSILENT PowerFactory software, finding for several cases favorable results, with minimal losses, representing for the system a better operational and economic condition.
