Implementation of control center based voltage and var optimization in distribution management system

This paper presents the implementation of an online voltage and var optimization (WO) application that runs at the control center for distribution systems. The innovative WO application combines state of the art optimization technology with detailed and accurate modeling of distribution systems. The multi-phase, unbalanced system model can have radial or meshed circuits, single or multiple sources, wye and/or delta connected transformers, grounded or ungrounded, voltage dependent load models, ganged or un-ganged controls of capacitor banks and voltage regulators. This application is capable of optimizing large and complex networks with online application speed. It is designed for smart grid application to optimize distribution energy delivery efficiency by minimizing the energy loss and manage system demand.
