Minimization of Transmission Loss in Application of HVDC Networks under Load Increase Scenario

Abstract

This study aims to analyze the effect of embedding HVDC (High Voltage Direct Current) on the voltage stability and power losses of the system. Sequential power flow is used to execute the combined AC-DC power flow by adjusting the estimation of DC slack bus injection to speed up convergence and to get more optimal results. Several systematic load increase scenarios are proposed in this study to provide stress loading on the system so that the performance of HVDC can be evaluated. This simulation was implemented on the IEEE 14-Bus System and IEEE 57-Bus System.
