Description of the research topic:
'Digitization is one of the driving forces of innovation, which involves communication and ease of use; substations of the power-system are no exception. The evolution of substations started with replacing the formerly analog/electronic devices with their digital counterparts. The next big challenge is digitizing the whole substation in a secure and efficient way. IEC 61850 was one of the key standards that enabled wide-scale, high level vendor independent communication. However, this was only the first step in a long road achieving a complete, robust, and secure system. Although many equipment and standards are available (for example: PRP, HSR, PTP based on Ethernet; or 5G), developing new concepts is still required.
New possibilities in protection, automation and control systems also appear along with this improved, flexible communication scheme. This means that the way an equipment works, reacts is now more defined by software and firmware rather than the actual hardware.
This paradigm shift even changes the way a substation is built: now the whole process is more of a complex configuration task, where even functions (which were formerly resided in a single device) could be distributed. The future will be self-healing and plug-and-play capability, where all this complex task of digital substations could be accomplished easier, faster, and less prone to human error. The candidate seeks answers – among others – to these questions:
• How can we provide plug-and-play operation for protection, automation, and control systems?
• How can we create an ICT infrastructure for substations that are self-healing, self-organizing in a plug-and-play fashion regarding currently attached devices?
• How can we manage software/firmware updates on-the-fly?
The research task is to develop new methods beyond the state-of-the-art, that are capable of:
• defining devices’ internal working autonomously as soon as they are connected to the substation, according to an abstract scheme.
• indicating which functions are currently missing from the substation compared to the abstract scheme due to absent of compatible devices.
• defining network infrastructure and issuing configurations autonomously for the connected devices, that is safe, reliable, and fast.
A special attention is made to robust, fault-tolerant and cybersecure operation. A hardware-in-the-loop (HIL) laboratory with cosimulation capabilities is available for experimenting with new ideas.
