System for achieving optimal steady state in power distribution networks
First Claim
1. A closed-form method for controlling an unbalanced, power-distribution network, comprising:
- a) deriving a formula, including a fundamental, explicit loss formula for a predetermined power-distribution network;
b) applying network flow programming techniques, incorporating said formula, directly to said power-distribution network in order to determine control steps necessary to achieve optimal, steady state therefor;
c) estimating the effect of said control steps on said power-distribution network prior to application thereof; and
d) performing said control steps on said power-distribution network in real time so as to control operation thereof.

Abstract
The present invention features a direct, closed-loop method for controlling an unbalanced, power-distribution network having a great number of nodes, branches and laterals, as well as multiphase loads. The network has a radial structure. One or more formulae are first derived for a power-distribution network. The formulae may be an explicit loss formula, a voltage formula, a line flow formula or any combination thereof. Network flow programming techniques which incorporate the formulae are then developed to directly achieve steady state. Finally, the control steps are performed on the power-distribution network in real time to control its operation. The control steps may include placing a capacitor, regulator or switch at a specific position in the network and/or reconfiguring the network in some other manner.
