FOR 1511:  Protection and Control Systems for Reliable and Secure Operation of Electrical Transmission Systems

• Subject Area: Computer Science, Systems and Electrical Engineering
• Term: from 2011 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 167470000

Liberalisation of electricity markets and increased volatile feed-ins by renewable energy sources have led to an operation of electrical transmission systems close to its admissible boundaries. In order to maintain operational security and reliability, new protection and control systems are needed. In this Research Unit, nine institutes at the TU Dortmund develop innovative protection and control applications for a highly dynamic real-time system management that particularly addresses the challenge to avoid large-scale system collapses (black-outs). New approaches to decentralised coordination of power flow controllers, protection of transmission corridors as well as overall system protection and control emerge from interdisciplinary research by researchers from electrical engineering, information technology, computer sciences and statistics.
The development of all aforesaid applications for power systems needs to take into account the close link to the information and communication infrastructure that provides the data for all monitoring and decision making processes. Nevertheless, the impact of underlying information and communication systems, which is of particular interest for protection and control of wide area transmission systems, is often neglected or modelled highly simplified. In order to explore robust and applicable approaches, focus has to be set on both new algorithms as well as explicit representation of information and communication technology (ICT).
Therefore, the goal of the Research Unit is to design a coherent solution for wide area system monitoring and protection of electrical transmission systems, considering all the way from formulation of innovative algorithms until realisation in an ICT-setting. The algorithms to be developed address improved system monitoring, improved system operation with regard to short-term problems due to overloading and oscillations, improved control based on new dynamic system information and automated protection for avoidance of system collapses. The development of a novel hybrid simulation of both power system as well as information and communication system shall enable the integrated investigation of the new approaches and the validation based on power system scenarios close to reality.
