Smart Power Flow Solvers for Smart Power Grids

摘要

A smart power flow solver integrates the TRUST-TECH based power flow methodology into a power flow solution. A first solver is applied to a power flow problem of a power system. If results of the first solver diverge, A Trust-Tech based solver is applied to the power flow problem by: transforming the power flow problem to an unconstrained global optimization problem; iteratively solving a dynamical system associated with the unconstrained global optimization problem; and determining whether a solution exists for the power flow problem based on whether the iteratively solving of the dynamical system converges. If a solution exists for the power flow problem, a second solver is then applied to the power flow problem. An operating state of the power system is generated based on results of the second solver to enable proper operation of the power system.
