Claim One:
1. A method of controlling voltages and power flows in a power network, comprising the steps of: obtaining on-line data of open/close status of switches and circuit breakers in the power network, obtaining on-line readings of real and reactive power assignments or settings at PQ-nodes, real power and voltage magnitude assignments or settings at PV-nodes and transformer turns ratios, which are the controlled variables/parameters, performing load-flow computation to calculate complex voltages or voltage magnitude corrections and voltage angle corrections at the power network nodes providing for the calculation of power flowing through different network components, and reactive power generation and transformer tap-position indications, evaluating the computed load flow for any of the over loaded power network components and for under/over voltage at any of the nodes, correcting one or more controlled parameters and repeating the computing and evaluating steps until evaluating step finds a good power system without any over loaded components and without any under/over voltages in the power network, and effecting a change in the power flowing through network components and voltages and phases at the nodes of the power network by actually implementing the finally obtained values of controlled parameters after evaluating step finds a good power system.
