1. On Efficient Transmission Balancing Operation : Capturing the Normal State Frequency and Active Power Dynamics
Sammanfattning : In an electric power system, there will always be an electric balance. Nevertheless, System Operators (SOs) often uses the term imbalance. Here, the term imbalance refers to the difference between trades and real-time measurements. LÄS MER
2. 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
3. Like a wave : Understanding the film and TV industries in Korea and Sweden
Sammanfattning : This doctoral dissertation is concerned with the complex dynamics of knowledge in the South Korean film and TV industry and Swedish filmmaking from a spatiotemporal perspective. The film and TV industries are highly dependent on knowledge and innovation. LÄS MER
4. Power System Oscillations - Detection, Estimation and Control
Sammanfattning : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. LÄS MER
5. Voltage Support of Transmission Grids Using Resources Located in the Underlying Lower Voltage Networks : Unlocking the Potential of Distributed Generation Reactive Power Capabilities
Sammanfattning : The path to sustainable, fossil-free future leads to inevitable energy transition towards renewable energy sources. A part of this transition includes replacement of conventional transmission system connected power plants with distributed renewables plants such as wind power. LÄS MER
