1. Off the grid
Sammanfattning : Off the grid is an artistic research thesis which puts a Swedish housing estate in a video interview dialogue with homeowners in the Northeastern US through focusing on three topics: travel, self-definition, and community. Based on the situated, visual and conceptual image the project merges seemingly incompatible experiences: eight residents in Husby, an immigrant community outside Stockholm, and eight households not connected to the utility grid, in upstate areas of New England and New York State – and two artistic researchers at University of Gothenburg.

Sammanfattning : This thesis is divided into two separate parts. The first part is about Dynamic Programming for non-trivial optimal control problems. The second part introduces some useful tools for analysis of stability and performance of systems with time-varying delays. LÄS MER
3. Modelling and control of a line-commutated HVDC transmission system interacting with a VSC STATCOM
Sammanfattning : The interaction of an HVDC converter with the connected power system is of complex nature. An accurate model of the converter is required to study these interactions. The use of analytical small-signal converter models provides useful insight and understanding of the interaction of the HVDC system and the connected system components. LÄS MER
Sammanfattning : This thesis deals with the modeling and control of pulse width modulated (PWM) voltage source converters connected to the grid. When voltage source converters are connected to the grid, the power quality and the dynamic performance are affected by the line filter connected between the converter and the grid, and by nonlinearities caused by the switching converter.

Sammanfattning : This thesis deals with the modelling and characterisation of THz planar Schottky diodes, focusing on analyses of geometry-dependent electrical parasitics and the thermal management of the diode chip. Moving towards higher operating frequencies, the diode performance degrades due to high frequency losses, parasitic couplings and self-heating effects. LÄS MER
