1. Millimetre wave waveguide enclosed grid frequency multipliers and imaging
Sammanfattning : The utilisation of the THz spectrum ( 0.3-10 THz ) is hampered by fundamental difficulties in generating power at these frequencies. LÄS MER
2. On-demand Restricted Delegation : A Framework for Dynamic, Context-Aware, Least-Privilege Delegation in Grids
Sammanfattning : In grids, delegation is a key facility that can be used to authenticate and authorize requests on behalf of disconnected users. In current grid systems,delegation is either performed dynamically, in an unrestricted manner, or by a secure but static method. LÄS MER
3. Grid-forming wind power plants
Sammanfattning : With growing concerns over climate change, the power system is witnessing an unprecedented growth in electricity generation from intermittent renewable energy sources (RES) such as wind and solar, which are commonly interfaced to the grid by power-electronic converters. However, increasing the penetration level of converter-interfaced generation units reduces the number of synchronous generators (SGs) in the grid that provide system services to support voltage and frequency, either inherently or through mandatory requirements and market products. LÄS MER
4. 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
5. Enhancing Privacy and Security in the Advanced Metering Infrastructure
Sammanfattning : Cyberphysical systems introduce computing and communication devices within different sectors of society generating large quantities of data. Information extracted from these data gives better understanding of these sectors and the systems within them. There are many ways in which the information extracted from these data can be harnessed.
