Assessing multiple operationally-stable power flow solutions in unbalanced impedance-grounded systems: initialization procedure and analysis
BC de Souza, LR de Araujo… - IEEE Transactions on …, 2020 - ieeexplore.ieee.org
The power flow is usually formulated by nonlinear equations and may present multiple
solutions. However, most of these solutions do not represent a practical situation but are
mathematical findings. Remarkably, in unbalanced multiphase systems with impedance-
grounded loads, a phenomenon can occur where two or more solutions may especially
show practical significance. These solutions are called operationally-stable solutions
(solutions which for a given loading level the nodal voltages, currents, and losses are …
