The Job

Do you expect to have a real impact on the energy transition? If yes, CEA-Liten is the ideal place for your PhD work. Our teams (1,000 people) are fully mobilised to develop the innovative solutions of tomorrow. Your role? to give birth to breakthrough innovations. Meet and join the 150 PhD students working in our laboratories, alongside with experienced researchers eager to transfer your discoveries up to the industrial stage. The proposed PhD subject contributes to the technological challenge “Solar energy for energy transition” ( more details ). The subject is “ DC-System based on Linear PV Systems integrated to existing AC grid ”. To achieve climate neutrality, a massive expansion of renewable energy (RE) is needed. However, onshore wind farms or open space PV are limited by the restricted space and social resistance. Therefore, a suitable solution is the exploitation of linear surfaces of hundreds of kilometers of existing infrastructure (e.g. road, motorway edges or railway) by a new linear PV system (LPVS). However, until now, the networks are not adapted to integrate these new quantities and types of EnR. Its architecture based on multi-terminal MVDC topologies can be extended to seamlessly integrate electric vehicles, storage (battery, hydrogen) and other renewable energies, e.g. wind power. Such a DC system can play an important role as a firewall to improve the reliability and resilience of the overall interconnect system. To fully exploit the potential of the DC system, it is necessary to address challenges such as, for example, architecture design, hybrid AC-DC planning, coordination of control and operation and asset management. This thesis aims to develop the LPVS with the following aspects: • Develop an innovative architecture for LPVS coupled with MVAC systems through an MVDC topology; • Explore the potential services of LPVS coupled with MVDC to maintain the reliability and resilience of the global interconnection system; • Demonstrate the functionalities of LPVS with dedicated simulations and laboratory tests with the MVDC laboratory • Assess the economic and social impact of the LPVS system while developing the technology.
