R&d Engineer On Hvdc Systems and Ac/dc Grid

Established in 2014, SuperGrid Institute is an independent private company with over 150 employees of 21 different nationalities. The institute is a key player for energy transition in France and throughout Europe, specialising in innovative high and medium voltage direct current (HVDC and MVDC) power systems. SuperGrid Institute also develops new technologies for the integration of renewable energies into the electricity networks of the future.

SuperGrid Institute has been ranked every year since 2018, reaching the podium 3 times in the INPI prize list.

**General context**

Integration of large amount of renewable energy sources (RES) (e.g., offshore wind, PV) and energy market integration are two of the main drivers for the future development of the pan-European power grid. This will require a reinforcement of the transmission grid to make it able to transport large amount of power over long distances from generation areas to load areas. Extended High-Voltage Direct Current (HVDC) grids, in Point to point or Multi-Terminal (MTDC) configuration covering large areas and distances, are considered to be the preferable solution for the reinforcement of the grid. Indeed, it has been understood that MTDC grids based on voltage source converter (VSC) technology are a key development for harnessing the offshore wind production potential of the North Seas. Those systems will be evolving from simple point to point and radial structures to complex meshed ones. To achieve their development, it is necessary to enhance their operating procedures with major challenges in control and protection, while considering the interaction with AC grid. Developing such HVDC systems together with the massive integration of RES, will result in a power system with more and more Power Electronics Interfaced Devices (PEIDs), Consequently, we will have to deal with significant impact on the integrated AC/DC transmission system characteristics (e.g., reduction of the system inertia) and behaviour.

**Objectives / Missions**

**HVDC/MTDC grids control and protection**

**AC/DC stability analysis of power network with embedded HVDC/MTDC grids**

This second topic focusses on the modelling, stability analysis and control of HVAC/HVDC transmission grids with high integration of power electronics devices. In the presence of high share of renewable energy, the control strategies of the power converters will have high impact on the stability of the whole AC/DC system.

Master 2 or PhD degree, with an experience in the field of power grid modelling, simulation, and control. Focus on HVDC systems and/or wind farms will be appreciated.
