11. Wind Power Integration in Power Systems with Transmission Bottlenecks
Sammanfattning : During the last two decades, the increase in electricity demand and environmental concern resulted in fast growth of power production from renewable sources. Wind power is one of the most efficient alternatives. LÄS MER
12. Probabilistic security management for power system operations with large amounts of wind power
Sammanfattning : Power systems are critical infrastructures for the society. They are therefore planned and operated to provide a reliable eletricity delivery. The set of tools and methods to do so are gathered under security management and are designed to ensure that all operating constraints are fulfilled at all times. LÄS MER
13. Ultra-Low Power InAs/AlSb HEMTs for Cryogenic Low-Noise Applications
Sammanfattning : The InAs/AlSb high electron mobility transistor (HEMT) is an emerging microwave device technology for ultra-low power and low noise applications. Due to the low bandgap (0. LÄS MER
14. Power System Damping - Structural Aspects of Controlling Active Power
Sammanfattning : Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. LÄS MER
15. Towards an on-chip power supply: Integration of micro energy harvesting and storage techniques for wireless sensor networks
Sammanfattning : The lifetime of a power supply in a sensor node of a wireless sensor network is the decisive factor in the longevity of the system. Traditional Li-ion batteries cannot fulfill the demands of sensor networks that require a long operational duration. LÄS MER
