Expansión del sistema eléctrico de potencia considerando conmutación óptima de líneas de transmisión.

Abstract

In this work, optimal transmission switching (OTS) and power electrical system (TEP) expansion planning are considered, tests will be performed on different electrical power systems (PMI), such as: Garver System and IEEE's 39-bar test system, precisely OTS relies on an analysis to determine line flow depending on the demand provided , to supply this load, but minimizing system costs based on initial parameters, in this optimization performed on both test systems, were performed using mixed linear programming (MILP), to determine binary variables, which determines whether transmission lines remain out of service or in operation, based on OTS results, are initial parameters for converging with TEP , it is done so that more than disconnect lines, which can redirect its flow, and supply the load, an expansion is planned for a multi-year period, which must be optimal and effective to supply the annual rising demand. The results obtained determined some non-viable features, i.e. in the default parameters in the system, they had to have some thorough modifications to converge the system and find an optimal solution. The moderate period will be seven years, just to justify its surplus percentage demand each year.
