Dynamic Averaged and Simplified Models for MMC-Based HVDC Transmission Systems

Presented by Hani Saad, Ph.D. R&D Engineer, RTE
Modular multilevel converters (MMCs) contain numerous IGBTs. The modeling of such converters for electromagnetic transient type (EMT-type) simulations is complex. Detailed models used in MMC-HVDC simulations may require very large computing times. Simplified and averaged models have been proposed in the past to overcome this problem. In this paper existing averaged and simplified models are improved in order to increase their range of applications. The models are compared and analyzed for different transient events on a MMC-HVDC system.
Hani Saad (S’07) received his B.Sc. and Ph.D. degrees in electrical engineering from the École Polytechnique de Montréal in 2007 and 2015, respectively. From 2008 to 2010 he worked at Techimp Spa. and in the Laboratory of Materials Engineering and High Voltages (LIMAT) of the University of Bologna on research and development activities. In 2014, he joined the French TSO RTE (Réseau de Transport d’Electricité), where he is currently involved in HVDC projects and EMT studies.
