1. Power System Stability Enhancement Using Shunt-connected Power Electronic Devices with Active Power Injection Capability
Abstract : Power electronic devices such as Flexible AC Transmission Systems (FACTS), both in shunt and series configuration, are widely used in the power system for power flow control, to increase the loading capability of an existing line and to increase the security of the system by enhancing its transient stability. Among the shunt-connected FACTS controllers family, the Static Synchronous Compensator (STATCOM) and the Static Var Compensator (SVC) are two key devices for reinforcing the stability of the AC power system.

2. Synchronous Voltage Reversal Control of Thyristor Controlled Series Capacitor
Abstract : 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.

3. Power System Security Assessment - Application of Learning Algorithms
Abstract : The last years blackouts have indicated that the operation and control of power systems may need to be improved. Even if a lot of data was available, the operators at different control centers did not take the proper actions in time to prevent the blackouts. READ MORE

4. Control of Dynamically Assisted Phase-shifting Transformers
Abstract : In this thesis, controllers for power oscillation damping, transient stability improvement and power flow control by means of a Controlled Series Compensator (CSC) and and a Dynamic Power Flow Controller (DPFC) are proposed. These devices belong to the group of power system components referred to as Flexible AC Transmission System (FACTS) devices. READ MORE

5. On Control of Grid-connected Voltage Source Converters - Mitigation of Voltage Dips and Subsynchronous Resonances
Abstract : Custom Power and Flexible AC Transmission Systems (FACTS) denote the application of power electronics in distribution and transmission networks, respectively. Custom Power is the application of power electronics to improve the quality of power distribution for sensitive industrial plants. READ MORE
