On the efficiency in electrical networks with ac and dc operation technologies: A comparative study at the distribution stage
This research deals with the efficiency comparison between AC and DC distribution networks that can provide electricity to rural and urban areas from the point of view of grid energy losses and greenhouse gas emissions ...
Second-order cone approximation for voltage stability analysis in direct-current networks
In this study, the voltage stability margin for direct current (DC) networks in the presence of constant power loads is analyzed using a proposed convex mathematical reformulation. This convex model is developed by employing ...
