Distributed generation modelling for unbalanced three-phase power flow calculations in smart grids
(2011-05-31)
Distributed Generators (DG) are generally modeled as PQ or PV buses in power flow studies. But in order to integrate DG units into the distribution systems and control the reactive power injection it is necessary to know ...

An analytical solution to the optimal power flow
(2002-03-01)
This letter presents an approach for a geometrical solution of an optimal power flow (OPF) problem for a two-bus system (slack and PV busses). The algebraic equations for the calculation of the Lagrange multipliers and for ...

Three-phase fast decoupled power flow
(1999-01-01)
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 ...
Substitution-newton-Raphson method for the solution of electric network equations
(2006-12-01)
The power flow problem, in transmission networks, has been well solved, for most cases, using Newton-Raphson method (NR) and its decoupled versions. Generally speaking, the solution of a non-linear system of equations ...
Sensitivity analysis for overload-relief in transmission lines using an implicitly coupled method (CRIC)
(2006-12-01)
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 ...

New representation of PV buses in the current injection Newton power flow
(2017-09-01)
This paper presents a comparative analysis of the influence of PV bus representation on the convergence characteristics of the Newton-Raphson Current Injection method. The methods used for solving the power flow problem ...
