21. Data-Driven Methods for Reliability Evaluation of Power Cables in Smart Distribution Grids
Sammanfattning : This research aims to develop data-driven methods that automatically exploit historical data in smart distribution grids for reliability evaluation, i.e., analyzing frequency of failures, and modeling components’ lifetime. LÄS MER
22. From data collection to electric grid performance : How can data analytics support asset management decisions for an efficient transition toward smart grids?
Sammanfattning : Physical asset management in the electric power sector encompasses the scheduling of the maintenance and replacement of grid components, as well as decisions about investments in new components. Data plays a crucial role in these decisions. LÄS MER
23. Cyber-security in Smart Grid Communication and Control
Sammanfattning : Society is increasingly dependent on the reliable operation of power systems. Power systems, at the same time, heavily rely on information technologies to achieve efficient and reliable operation. LÄS MER
24. Increasing the hosting capacity of distributed energy resources using storage and communication
Sammanfattning : This thesis develops methods to increase the amount of renewable energy sources that can be integrated into a power grid. The assessed methods include i) dynamic real-time assessment to enable the grid to be operated closer to its design limits; ii) energy storage and iii) coordinated control of distributed production units. LÄS MER
25. Data analytics for weak spot detection in power distribution grids
Sammanfattning : This research aims to develop data-driven methods that extract information from the available data in distribution grids for detecting weak spots, including the components with degraded reliability and areas with power quality problems. The results enable power distribution companies to change from reactive maintenance to predictive maintenance by deriving benefits from available data. LÄS MER
