Distribution networks and Smart Grids
Development of methods for distribution network planning and operation and information system applications are one cornerstone of the Unit. The Unit has long traditions in distribution network related issues over several decades relating e.g. to developing network information systems and calculation applications for network planning and comprehensive distribution management system for network operation purposes.
Recently the research in this field has gone under the umbrella of Smart Grids which has increased the distribution level research activities considerably worldwide. Smart Grids has not an intrinsic value but it is a tool to achieve e.g. theEU commission 20/20/20 target. In general Smart Grids has two main aspects: Enabler of energy-efficient and environmentally friendly energy market and critical infrastructure of society. On-going research is closelyrelated to these functions including following focus areas.
- active network management and integration of distributed generation
- distribution protection and automation
- condition monitoring
- power quality management
- reliability analysis and asset management
- management of major distrubances
- automated meter reading systems in network management
- interactive customer interface
- network impacts of electric vehicles
- power electronics in electricity distribution
- power transmission
- electricity market
Research laboratories and equipment includes e.g. real time digital simulator (RTDS), and dSPACE simulator integrated with RTDS, various simulation softwares like PSCAD, PSS/E, PowerWord, DigSilent, Matlab, Simulink, TN-Flash, Distribution automation system (SCADA, DMS) by ABB systems and Reliability based network analysis –software developed by the Unit, home automation development platforms, and versatile field measurement devices for on-line and off-line PD measurement and power quality measurements.
Main research personel of this area are prof. P. Järventausta, prof. P. Verho, prof. H. Tuusa, associate prof. S. Repo, PhD P. Pakonen, PhD A. Nikander and 17 Doctoral Students.
