Supergrid Architecture & Systems

“To make the energy transition a success, electricity grids must have the capacity to integrate renewable energies on a massive scale, via direct current (DC) components. SuperGrid Institute provides expertise to develop the technologies and associated analytical methods needed to guarantee the smooth operation of interconnected AC and DC networks.“
Jean-Baptiste HEYBERGER, Department Director – Supergrid Architecture & Systems
SuperGrid Institute’s experts work to overcome the technical challenges confronting DC grids. We develop technologies to control and protect the stability of HVDC and MVDC networks, which need to be much more dynamic than AC networks. Defining the requirements for the key components of DC grids or combined AC-DC power systems and designing and simulating the technical performance of these systems are key to our work.
We employ real-time, electromagnetic transient simulations with accurate, built-in models of power converter control systems to demonstrate how a system will perform when a new technology is integrated into the network (for example, a new protection strategy).

Thermal Measurement of Asymmetric Losses in a Submodule of an Isolated Modular Multilevel DC-DC Converter
This study experimentally quantifies asymmetric losses in an Isolated Modular Multilevel DC-DC Converter (IM2DC) submodule, showing that low-side devices can dissipate up to twice the losses of high-side devices. A thermal imaging-based calorimetric method provides accurate, nonintrusive measurements, supporting future optimization of converter design, thermal management, and reliability.
