Internship – Control of HVDC Transmission systems in grids with high integration of renewable energies

Posted 2 months ago

SuperGrid Institute brings together 180 employees of 28 different nationalities who work together within a dynamic environment in the city of Lyon. As an independent research and innovation centre, we are dedicated to developing technologies for the future power transmission system, the “supergrid”, including HVDC & MVDC technologies.

As a multi-disciplinary research centre with advanced simulation capabilities & multiple test platforms, including numerous associated laboratories, SuperGrid Institute uses its comprehensive expertise to provide a wide range of services and solutions to support our customers in developing power systems, equipment and components. We specialise in system architecture and work on ensuring network security and stability while allowing for the integration of intermittent renewable energy sources.

General Context

The ongoing large-scale integration of renewable energies (RES) in Europe is leading to important changes in the structure and operation of the transmission system. Indeed, transitioning the production from fossil fuels to wind and solar power (generally connected via power electronics) generation leads to dramatic changes in power flows across AC transmission networks that, as a result requires a major upgrading. In this context, High-Voltage Direct Current (HVDC) has proven to be the most adapted technology for the reinforcement and upgrading of the transmission system. Moreover, recent projects (see the European project MIGRATE) have shown that as the integration of renewable energies interfaced by power electronics together with the de-commissioning of conventional power plants leads to a system with reduced inertia, i.e. more volatile. SuperGrid Institute has performed research on solutions to successfully operate power electronics converters interfacing RES in grids with high integration of power electronics known as grid-forming controls. These concepts need to be adapted for their application to HVDC transmission systems either in Point-to-point or in Multi-terminal configuration.

Objectives / Missions

The objective of the work is to identify the limits of the grid-forming control strategies when the converters are used in an HVDC transmission link (or HVDC in Point-to-Point configuration) embedded in an AC grid. Then, modifications to the existing grid-forming control algorithms will be proposed to allow them to be used in HVDC transmission systems. The study is based on previous works from Supergrid Institute (see for instance  https://ieeexplore.ieee.org/document/9640024 and https://www.researchgate.net/publication/346985007_Dynamic_control_of_embedded_HVDC_to_contribute_to_transient_stability_enhancement ).

The planned workflow is as following.
