Computational system for training and simulation of volt/VAr control actions

This paper presents a computational system to support real time Volt/VAr control actions in an EMS or DMS environment. The system can be used in on-line mode (monitoration, simulation and optimization) with information from SCADA, parameter database and state estimator, and off-line mode (training and past simulation and optimization), which information (operational point and topology network) are obtained from a historic on-line database. It runs automatically in the monitoration mode and on demand in simulation and optimization mode. This system is running in a regional utility in Brazil (RGE utility) since 2002. The final tests are being done to validate the final application.
