A Model Predictive Approach to Voltage Control in Power Systems

Back
Abstract:
The presentation will describe some general aspects of voltage control in power systems, with an emphasis on the determination of control actions aimed at preserving voltage stability under stressed operating conditions. A model of the controlled system, including the network and load dynamics, is used to predict the future system behaviour based on the current state and applied control actions. The optimal control state according to these predictions is then obtained using a search method similar to those used in chess computers. A detailed and three simplified predictors are presented, along with a tuning procedure that aims to ensure that a minimum amount of emergency control is scheduled by the controller is described.
