Sammendrag

The transition towards a zero-CO2 emission system requires numerous transformations in energy systems, which involve not only the integration of renewable energy sources, but also the incorporation of a digitalisation process.

Thanks to advanced ICTs, traditional energy systems have transformed into cyber-physical and power systems (CPEPS). This paradigm shift goes beyond traditional technologies, opening new opportunities and breakthroughs to the energy infrastructure. 

This PhD thesis proposed a novel cyber-physical convergent purpose technology, where a set of independent technologies (protection/controllers, virtualisation, digital communication technologies, etc) is integrated into the cybernetics layer, through investigations about control and protection functionalities under dynamic behaviours of power grids.

Within the laboratory facilities, the virtualised environment is constructed for both protection and control functionalities to perform research, tests, and validations. Furthermore, leveraging the capability to exchange data through communication protocols via Local Area Network (LAN), the CPEPS testbeds are utilised to conduct research in modern energy systems. The real-time simulation and hardware-in-the-loop methods also strengthen the research by validating proposed protection and control algorithms.

In summary, this PhD thesis offers a comprehensive exploration of CPEPS, focusing on cyber-physical convergent technologies. Under the uncertainties inherent in power grids, the research work plays a part in opening a new horizon for the development of control and protection strategies. The findings continue contributing to the ongoing efforts in decarbonisation, digitalisation, and the broader transition towards sustainable energy systems.
