SmartGrid is the natural evolution for the control and optimization of electric grid operation, improving quality of service and reducing costs. The implementation of the SmartGrid means evolving the SCADA and DMS systems from systems that aid humans in the management of the power network to intelligent semiautonomous systems with a reduced human element. The introduction of Distributed Energy Resources (DER) and Demand Response (DR) are changing the character of the electrical network managed by the new systems. Consumers pass from clients to active agents, contributing interactively [1] to network management and thus Quality of Service (QoS). This paper indicates how the new systems must use selfdescribing equipment, standardised data models and protocols, must integrate with other corporate systems as both information vendors and purchasers, to achieve these while maintaining high data quality with acceptable costs of data capture and maintenance
The paper presents the results of the MONITOR BT project with special focus into faults detection and their location in the low voltage (LV) grid and in public lighting feeders. The fault detection and location algorithms run in the Distribution Transformer Controller (DTC) deployed in secondary substation who receive data from monitoring sensors deployed along the LV grid that communicate via RF-mesh. The pilot demonstration of the system was implemented over a selected LV network in Portugal generating results that are also discussed in the paper.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
