The management of Distributed Energy Resources for voltage control in smart grids

Using the communication infrastructure and management that created in smart grids, end-user reactive power capable devices can be coordinated for voltage support. In smart grids, Energy Management System (EMS) is responsible for network management. On the other hand, Distribution Management System (DMS) can be used in very widespread grids to make some of the decisions for network management. In this paper, a new framework for voltage control in distribution feeder based on the decentralize manner has been presented. In this method, the DMS is used for making the decisions and the central EMS supervises to the decisions that make by DMS. For this purpose, a three-layer management system is developed and resources are grouped. Consequently, results are implemented in 69-bus distribution network.
