1. Power control strategies for renewable energy systems : The inverter's role in future power systems
Sammanfattning : Connecting more non-dispatchable renewable energy sources (RESs) will result in a higher power variability and a lower system inertia when the synchronous generators are replaced by inverter-connected RES. Inverter control can be divided in three categories: grid-following, grid-forming (GFM) and grid-supporting. LÄS MER
2. On Power-system Benefits, Main-circuit Design, and Control of StatComs with Energy Storage
Sammanfattning : Static synchronous compensation (StatCom) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, StatComs are employed for reactive power support only. LÄS MER
3. Steady State Operation and Control of Power Distribution Systems in the Presence of Distributed Generation
Sammanfattning : In this thesis, the impact of distributed generation (DG) on steady state operation and control of power distribution systems is investigated. Over the last few years, a number of factors have led to an increased interest in DG schemes. DG is gaining more and more attention worldwide as an alternative to large-scale central generating stations. LÄS MER
4. 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
5. Synchronous Voltage Reversal Control of Thyristor Controlled Series Capacitor
Sammanfattning : Series compensation of transmission lines is an effectiveand cheap method of improving the power transmission systemperformance. Series capacitors virtually reduces the length ofthe line making it easier to keep all parts of the power systemrunning in synchronism and to maintain a constant voltage levelthroughout the system.
