This thesis addresses the transient stability analysis of hybrid AC/DC electric transmission systems. More precisely two questions sought to be investigated: What is the impact of a DC contingency on AC transient stability? How can we take advantage of the DC transmission systems as control inputs in order to enhance AC transient stability?
SuperGrid Institute is delighted to have signed a framework agreement with the CNAM (Conservatoire National des Arts et Métiers) regarding training and in particular around supergrid and HVDC technologies. This agreement covers lifelong learning, technology research and the provision for scientific and technical proficiency.
This paper presents a methodology to consider the impedance of a grid in power hardware in the loop (PHIL) experiments to validate power converter control in presence of harmonics or resonances in the network impedance. As the phenomena to emulate are in a large frequency range, the skin effect in conductors has to be taken into account. A procedure is developed to model the network.
