1. Fundamental Control Performance Limitations for Interarea Oscillation Damping and Frequency Stability
Sammanfattning : With the transition towards renewable energy and the deregulation of the electricity markets, the power system is changing. Growing electricity demand and more intermittent power production increase the need for transfer capacity. Lower inertia levels due to a higher share of renewables increase the need for fast frequency reserves (FFR). LÄS MER
2. On Frequency Control Schemes in Power Systems with Large Amounts of Wind Power
Sammanfattning : In recent years, large investments have been made in wind power, and this trend is expected to continue in the coming decades. Integrating more wind power in the production mix offers great opportunities for the society, such as reducing greenhouse gas emissions and the dependence on foreign fuel. LÄS MER
3. Adaptive Measurement Strategies for Network Optimization and Control
Sammanfattning : The fifth generation networks is rapidly becoming the new network standardand its new technological capabilities are expected to enable a far widervariety of services compared to the fourth generation networks. To ensurethat these services can co-exist and meet their standardized requirements,the network’s resources must be provisioned, managed and reconfigured ina far more complex manner than before.

4. On Power Control and Scheduling to Mitigate Adjacent Channel Interference in Vehicle-to-Vehicle Communication
Sammanfattning : Safety applications play an essential role in supporting trac safety and eciency in next generation vehicular networks. The eciency of safety applications depends heavily on the establishment of reliable communication since these types of applications have strict requirements on latency and reliability. LÄS MER
5. Modeling of Modular Multilevel Converters for Stability Analysis
Sammanfattning : Modular multilevel converters (MMCs) have recently become the state-of-the-art solution for various grid-connected applications, such as high-voltage direct current (HVDC) systems and flexible alternating current transmission systems (FACTS). Modularity, scalability, low power losses, and low harmonic distortion are the outstanding properties that make MMCs a key technology for a sustainable future. LÄS MER
