1. Voltage Source Converters with Energy Storage Capability
Sammanfattning : This project deals with voltage source converters with energy storage capability. The main objective is to study the possible benefits of energy storage to a power system with a VSC as the interface between them. First of all, a converter control system is proposed for a two level VSC. LÄS MER
2. Grid-Connected Voltage Source Converter - Control Principles and Wind Energy Applications
Sammanfattning : The thesis focuses on a forced-commutated voltage source converter (VSC) connected to a grid in a wind energy application. The work consists of four parts. The first part addresses the type of electrical system which should be used in a wind turbine. LÄS MER
3. Wind Turbine Characterization by Voltage Source Converter Based Test Equipment
Sammanfattning : In countries where wind power has become a relevant part of the total generated electrical power, transmission system operators (TSOs) have included in their Grid Codes specific technical requirements for interconnection of wind power plants. Some Grid Codes demand specific testing procedures in order to verify the fulfilment for their requirements. LÄS MER
4. Modeling and Control of Voltage Source Converters Connected to the Grid
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.
