Electrical energy within the EMPP research department is based on several experimental platforms dealing with different themes:

Electrical drives: This is a set of equipment for testing and simulating electromechanical conversion chains: “source-converter-motor-load” at different power levels. It is a platform for validating new electric motor or converter topologies for various applications such as transportation or electric mobility. The platform is equipped with rapid prototyping systems for electric machine control (dSPACE), several electric motor benches and their environments, as well as climatic chambers or ovens for studying devices at different temperature levels ranging from -50 °C to 500 °C.

Microgrids: The Microgrid Multi-Vehicle Platform enables the implementation of different energy management laws to control power flows in multi-load multi-source AC and DC microgrids, combining different energy vectors such as hydrogen, electricity and heat. These microgrids are built around specific architectures allowing the connection of different autonomous generators, consumers, renewable energy sources and different storage systems. Depending on the presence or not of a communication network, different classes of energy management algorithms can be implemented. Therefore, we differentiate microgrids with communication networks between producers and consumers (centralized or distributed management) or without communication network (decentralized management). The main objectives concern the search for optimal power architecture taking into account energy efficiency and network quality, but also durability, availability and reliability.

These platforms are based on theoretical know-how in terms of characterization, design and control of electrical systems. They are shared between GREEN and LEMTA researchers from the EMPP research department of the University of Lorraine.
