Continuation Three-Phase Power Flow: A Tool for Voltage Stability Analysis of Unbalanced Three-Phase Power Systems [PDF]

IEEE Transactions on Power Systems, 2005
In this paper, a continuation three-phase power flow (CTPFlow) approach in polar coordinates, which can be used to analyze voltage stability of unbalanced three-phase power systems, is proposed. Using CTPFlow, the PV curves of unbalanced three-phase power systems can be obtained.

Three-phase fast decoupled power flow [PDF]

PowerTech Budapest 99. Abstract Records. (Cat. No.99EX376), 2003
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 fast decoupled methods and the current injection Newton work for radial and meshed networks, and the matrices (Jacobian) remain ...

Unified power flow controller models for three-phase power flow analysis [PDF]

Electrical Engineering, 2005
In this paper, three models of the unified power flow controller (UPFC) suitable for three-phase power flow analysis in polar coordinates are presented. The symmetrical components control model can be used to control the positive-sequence voltage of the shunt bus and the total three-phase active and reactive power flows of the transmission line while ...

Three-phase converter models for unbalanced radial power-flow studies

IEEE Transactions on Power Systems, 2002
This paper presents a power converter model intended for both balanced and unbalanced radial power flow studies. A three-phase steady state model of a power converter (ac/dc-dc/ac) composed of a diode rectifier, a loss-less dc link, and a pulse-width-modulated inverter is presented.
