Three-phase optimal power flow based on Affine Arithmetic
(2021-09-15)
This 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 ...
Performance Analysis of Three-Phase Power Flow Algorithms in Power Distribution Networks
(2021-01-01)
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 ...
Análise comparativa de correlações para o fator de atrito interfacial em escoamentos gás-líquido no padrão anular em tubulações
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2015-12-03)
The two-phase flow is a flow of two diferente componentes or phases. This flow may be an anular flow where one phase or componente flows forming a film layer over the other phase or component. The two-phase flow may be ...
