A compensation technique for unsymmetrical three-phase power flow
2016 International Symposium on Industrial Electronics (INDEL), 2016This paper presents the implementation details of a power flow method for unbalanced three-phase distribution networks. The proposed technique utilizes the current injection (CI) method for power flow calculation and considers the modeling of unbalanced loads, load tap-changing (LTC) transformers, and shunts capacitors.

Three-Phase Optimal Power Flow based on Affine Arithmetic
2021 IEEE PES Innovative Smart Grid Technologies Conference - Latin America (ISGT Latin America), 2021This paper presents a non-linear stochastic mathematical formulation for the three-phase optimal power flow problem, which addresses the uncertainties of both the load and the renewable generation using the self-validation method called Affine Arithmetic. The affine shapes for tree-phase variables was performed using the theoretical approach of Reduced

Robust three phase fast decoupled power flow
2009 IEEE/PES Power Systems Conference and Exposition, 2009In this paper, a robust, three-phase, fast-decoupled power flow (FDPF) is developed for transmission system, using Optimal Multiplier. An efficient non-divergent, three-phase power flow is required for the analysis of ill-conditioned or highly stressed systems. Such situations are more common in unbalanced systems.

Three-phase high power factor rectifier with unidirectional power flow
The Fifth International Conference on Power Electronics and Drive Systems, 2003. PEDS 2003., 2004This paper presents a three-phase multilevel rectifier with reduced power switches to achieve high power factor, low harmonics and high voltage capability. In the conventional three-phase neutral point clamped rectifiers, twelve power switches are used to draw the sinusoidal line currents with unity power factor.

The Existence of Multiple Power Flow Solutions in Unbalanced Three-Phase Circuits
IEEE Power Engineering Review, 2002This paper presents a new phenomenon found for unbalanced power flow solutions: the existence of two voltage solutions at the neutral points of unbalanced three-phase circuits. The phenomenon is different from that found in traditional single-phase balanced power flow solutions. It is dependent on the degree of system or load unbalance.

Model and method for power flow calculation of three phases power system with UPFC
2011 International Conference on Electrical and Control Engineering, 2011Based on additional nodal power injection method, this paper presents nodal power injection model of UPFC for three phase power flow calculation. Based on this model, use decoupling-compensation theory to calculate three phases power flow. Finally, the rationality and effectiveness of three phase load flow with UPFC is verified by the simulation.
