Optimal location and sizing of PV sources in DC networks for minimizing greenhouse emissions in diesel generators
This paper addresses the problem of the optimal location and sizing of photovoltaic (PV) sources in direct current (DC) electrical networks considering time-varying load and renewable generation curves. To represent this ...
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 ...
A New Iterative Power Flow Method for AC Distribution Grids with Radial and Mesh Topologies
This brief discusses the classical problem of power flow analysis in alternating current (ac) distribution networks through Taylor series expansion. The main advantage of this approach is that it can work with radial and ...
Hybrid ga-socp approach for placement and sizing of distributed generators in DC networks
This research addresses the problem of the optimal location and sizing distributed generators (DGs) in direct current (DC) distribution networks from the combinatorial optimization. It is proposed a master–slave optimization ...
