This paper presents power flow methods for the solution of unbalanced and balanced three-phase distribution systems. The best existing methods for solving three-phase power flow are tested and the results discussed. The ...

The restructuring of energy markets to provide free access to the networks and the consequent increase of the number of power transactions has been causing congestions in transmission systems. As consequence, the networks ...

In this paper, it is analyzed two algorithms to calculate the three-phase power flow in electricity distribution networks. The algorithm should be able to present an effective convergence to unbalanced networks spending ...

In this paper a framework based on the decomposition of the first-order optimality conditions is described and applied to solve the Probabilistic Power Flow (PPF) problem in a coordinated but decentralized way in the context ...

In this paper an interactive program developed to study of the continuation power flow is presented. Both, the graphical user interface and the power flow program have been developed in the Matlab environment thus providing ...
