A novel 60 MW Pulsed Power System based on Capacitive Energy Storage for Particle Accelerators
Résumé
Large physics experimentation as in particle accelerators or in nuclear fusion is often characterised by a strong and modulated power demand, incompatible with the power availability of the grid. Therefore, large facilities for short-term energy storage have been used, traditionally based on rotating machines. Several new solutions of power supply are studied and especially a new solution for energy storage is presented, where capacitors are used as energy storage elements. They are integrated in the static power converter. The energy- and instantaneous power-demand are presented, and then the global storage system with a dedicated multilevel DC/DC converter with flying capacitors is described. A specific control strategy for voltage balance, together with an adapted loss compensation method is also introduced and developed.

Stockage de l'énergie
Le stockage de l'énergie consiste à mettre en réserve une quantité d'énergie provenant d'une source pour une utilisation ultérieure. Il a toujours été utile et pratiqué, pour se prémunir d'une rupture d'un approvisionnement extérieur ou pour stabiliser à l'échelle quotidienne les réseaux électriques, mais il a pris une acuité supplémentaire depuis l'apparition de l'objectif de transition écologique.

Thermal energy storage
Thermal energy storage (TES) is achieved with widely different technologies. Depending on the specific technology, it allows excess thermal energy to be stored and used hours, days, months later, at scales ranging from the individual process, building, multiuser-building, district, town, or region. Usage examples are the balancing of energy demand between daytime and nighttime, storing summer heat for winter heating, or winter cold for summer air conditioning (Seasonal thermal energy storage).
