Abstract:
A multiphase optimal power flow method for limiting unbalances of currents in equipments using reactive compensation is proposed in this paper. The equipment modeling is based on current injection method in rectangular coordinates. The method was implemented and the proposed computational tool was developed with Matlab® and Lingo® softwares. This document presents the mathematical models of electrical components, operative constraints and some objective functions. Some cases are presented to show the efficiency of the proposed method.
