Abstract

Modern distribution systems are migrating from a passive, non-supervised structure to an active, supervised structure due to the introduction of distributed generators and distributed metering/monitoring/control devices. In this context, utility grids are in demand for the development of new techniques of control, protection and monitoring to be introduced in Distribution Management System (DMS). Voltage profile control is one of the most important DMS function, but it has had its performance affected by the increasing penetration of micro and mini Distributed Generation (DG). In addition, it is well-known that the connection a DG is likely to raise the voltage on its terminal as well as on nearby loads. Consequently, traditional methods of voltage control are inappropriate in this scenario. Therefore, it is necessary to develop methods and strategies of control that takes into account the impact of DGs and that takes advantage of the resources provided by smart grid solutions (e.g., smart meters). From conceptual point of view, there are three control strategies to be considered: localized control, decentralized control and centralized control; which demand increasing levels of communication and complexity. This M.Sc project aims to investigate and propose methods to enable these three control strategies to perform properly in a high penetration scenario of micro and mini DG. The main objective is to extend the knowledge about this relevant issue to all stakeholders: distribution companies, generators and customers. Real data from Brazilian and Canadian grids will be used to confirm, evaluate and improve the developed methods, which will be tested through computational simulations. (AU)
