Advanced utilization of big data for real-time monitoring and data analytics in Sundom smart grid
Modern technologies are increasingly used in many protection, control and monitoring solutions for power distribution grids. Voltage and current measurements are nowadays usually converted to digital signals, which are ...
Multi-objective active network management scheme studied in Sundom smart grid with MV and LV network connected DER units
Use of controllable, flexible, distributed energy resources (DER) in MV and LV networks will be in key role in order to improve local and system-wide grid resiliency and maximize utilization of renewable energy sources ...
Alternative solutions for advanced security of supply
(International Conference and Exhibition on Electricity Distribution CIRED, 2019-06-01)
The restrictions regarding the maximal length of outages especially under major storms has resulted in massive underground cabling projects in the network companies in Finland and Sweden. Due to these expensive investments ...
Utilization of a mixture of CTs and current sensors in line differential protection applications
The popularity of Rogowski sensors is increasing due to their advantages over conventional CTs. Consequently, network utilities may sometimes end up facing a question whether it would be possible to use line differential ...
Novel protection approach for MV microgrid
The amount of distributed generation (DG) connected to medium voltage (MV) networks is expected to increase continuously. This trend creates a good opportunity to use MV feeders as microgrids. Normally ...
Sensitivity analysis of frequency and voltage stability in islanded microgrid
This paper studies the voltage and frequency stability of an islanded microgrid and the sensitivity of these quantities to certain changes in system configuration. In conventional power systems the system frequency ...
Fault type and location detection in islanded microgrid with different control methods based converters
In this paper the fault type and location detection in an islanded low voltage (LV) distribution network based microgrid with converters applying different control methods is studied. In the ...
Protection system for future LV microgrids
Traditional protection of low voltage (LV) network will not be applicable for future LV microgrids and new adaptive protection system must be developed. In this paper adaptive protection system for LV microgrid during ...
