Planificación del sistema de transmisión incorporando los variadores de fase como controladores de flujo de potencia

Abstract

The demand dynamics directly influences the power flows that circulate through the transmission lines of the electrical system, this variation affects the phase angle of the voltage in each link of the network, disturbing the chargeability of the lines, in response to this effect. The extension of new lines is incurred, meaning considerable investment costs, which is why it is necessary to consider other actions within the transmission system expansion planning studies to readjust the network, one of these is the implementation of elements such as variators phase as a means of controlling the power flow and it is economically more profitable but also without neglecting the inclusion of new lines if necessary. For this reason, the present research work is developed proposing an optimization model formulated in GAMS that minimizes the investment costs of the network and of operation in the generation considering technical restrictions of the system, determining the location of the phase variators and new links as a result, better operability is obtained by redistributing the power flows, reducing the chargeability of the lines with the incorporation of the aforementioned elements.
