Introduction

This research program is chiefly concerned with the theory and applications of technical and economical control of power systems in order to achieve robust and efficient operation with optimal reliability in the framework of the deregulated electricity markets.

Research projects

  Security-centered coordinated control for efficient use of AC-DC controllable transmission systems

This research project is concerned with the investigation of the possibility to enhance power system stability and efficiency by coordinating several flexible ac-dc components.
  Development and analysis of efficient controllable power system components

The aim of this project is to develop and analyze suitable models of controllable power system components that enhance the possibilities of using these components and provide insights into the impact that the components have on the system.
  Coordination of system protection and HVDC/FACTS controllers to mitigate cascading failures in large interconnected power systems

The aim of the project is to develop power system topologies with HVDC and/or FACTS interfacing the various sub-systems of the interconnected power grid and coordination their protection and control in order to reduce the risk of system-wide failures.
  Regulation for effective transmission systems on deregulated electricity markets

This research project aims at developing methods to investigate the consequences of different choices for regulation concerning operation and expansion of the transmission grid.
  Control of classical and VSC-based HVDC transmissions connected to weak grids

The objective of the project is to investigate dynamical problems related to HVDC connections to weak grids. Special emphasis will be put on the interaction between VSCbased HVDC and classical HVDC.
  Impact studies of FACTS controllers on power system performance

The objective of this project is to study how the transmission capacity of a power system can be improved by efficient usage of new Flexible AC Transmission Systems (FACTS) devices and control controllers.
