Take part in OPAL-RT Zürich Conference on September 17th-18th, 2019!

RTE is sponsoring OPAL-RT’s Zürich conference on September 17th-18th, 2019. Let yourself be inspired by the speakers who will present the latest trends in real-time simulation solutions for power systems and power electronics.

Location: Casinotheater Winterthur, Stadthausstrasse 119, 8400 Winterthur, Switzerland



Come at Zürich and meet Hani Saad, HVDC Technical Expert at RTE

His presentation will illustrate how replicas are used at RTE to improve system operation since 2011. This solution will be presented with real events that occurred on the French grid with HVDC devices.




The use of real time simulation to derisk HVDC and FACTS schemes


Several projects involving power electronic based equipment such as HVDC links, static VAR compensators and wind power plants have been decided and build by RTE. In the long term, the share of power electronics connections into existing ac systems will significantly increase due to the massive penetration of wind power plants and HVDC links. For several years, the French TSO (Transmission System Operator) RTE, has been involved in research and development activities to model and study power electronic devices. To support these activities, numerical tools are needed that offer detailed modeling HV components and controls while maintaining a good compromise between robustness, accuracy, and flexibility.

Special incidents are presented, that is: DC cable fault event and AC emulation behavior due to inter-area oscillation. Also, the paper explains how real-time simulation with physical controls supports maintenance, training and R&D activities by providing robust and reliable tool.


Hani Saad (received his B.Sc. and Ph.D. degrees in electrical engineering from the Polytechnique of 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 R&D activities. In 2013, he joined the French TSO RTE (Réseau de Transport d’Electricité), where he is currently involved in HVDC projects as a technical expert and in EMT studies.
