Context, Integration in the project dynamics
Micro-grids are progressing when self-consumption of electricity produced by renewable energies becomes a credible option. In that case, energy storage is a critical issue. The aim is to develop a more reliable multi-carrier micro-grid, in which two energy carriers are involved: hydrogen (used as an electricity storage mean) and electricity. The key elements allowing the interconnection of the two networks will be thoroughly studied in terms of both electrochemical and electrical topologies as well as fluid management.
Innovative aspects and cross-disciplinary collaborations
A recent patent of the LEMTA lab dealing with PEMFC structure will be enhanced by a specific power electronic static converter interfacing with a micros-grid. The objective is to design a power electronic device which allows optimizing both reliability and lifetime of the electrochemical components in the framework of a multi-carrier micro-grid.
Targeted scientific advances from the state of art
Dynamic model including interactions in a multi-carrier micro-grid, understanding of the aging mechanisms of the electrochemical systems when they are connected to a micro-grid.
Description of the subject
This work will be done in two steps. First, the characterization of the key components, specifically the PEM fuel cell and the electrolyzer, has to be performed. Then, a specific power electronic converter giving additional degrees of freedom in energy management has to be designed for connecting the above mentioned components to the micro-grid. Furthermore, a dynamic model of the multi-carrier micro-grid has to be developed. It allows analyzing control and energy management strategies of the micro-grid taking into account the effect of electrical stresses on aging of electrochemical components.
The final step of this work will consist in developing a design procedure for multi-carrier H2-electricity micro-grids as a function of the load profile of the two networks. This will be realized through defining an optimization problem with static, dynamic and lifetime constraints.

Each candidate may submit an application on up to three separate research topics.
Application analysis period by each graduate school
The graduate school reviews the applicants for a doctoral contract in the relevant disciplines. They check the level of supervision for each supervisor and the situation of trained doctors. Each candidate will meet the laboratory director, supervisor and a representative from the graduate school. This interview is to identify the candidate’s motivations and suitability as a candidate for the PhD project proposed by the supervisor. A recommendation will be made to the graduate school. This will summarize the strengths and/or weaknesses of the application.
PhD grants will include monthly income for the PhD student (roughly 1700 € for research only, complement can be provided for teaching missions) and environment for research in the research unit.
Please be aware that in order to offer a variety of subjects, more positions are posted here than available funding. The LUE executive committee will make the final choice on the granted funding (up to 12 positions), based on the recommendations by the doctoral schools.
