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 gri the power quality and the dynamic performance are affected by the line filter connected between the converter and the gri and by .

Abstract—In this paper, a novel control method of grid-con- nected voltage - source converters ( VSCs) is proposed. The method can be generally applied for all grid-connected . This is achieved through an electronic converter and its ability of converting electrical energy from AC to DC or vice versa.

There are basically two configuration types of . Multi terminal operation possible but hard. Experience from the design and commissioning of the transmission shows that the technology has now reached the stage where it is possible to build high voltage converters utilising. The work consists of four parts.

The conclusion is to use variable-speed wind turbines, due to higher . This appendix describes the operating principles and modulation methods of the most com- monly used voltage source converter (VSC) topologies. In addition, a number of illustrative examples are provided to aid in the understanding of the relevance of each converter and its power system application(s). Since VSCs do not require commutating voltage from the connected ac . A thesis submitted to attain the degree of. Doctor of Sciences of ETH Zurich. MSc ETH EEIT, ETH Zurich born on 13.
