Can energy storage fusion power supply be used in superconducting magnets?

In order to reduce the impact of large-capacity fusion power supply on the power grid and make full use of the energy in superconducting magnets, this study proposed a hybrid and multi-element novel energy storage fusion power supply topology.

What is a dual-system energy storage system?

By utilizing a combination of strategically located lithium-ion batteries and supercapacitors within the power supply structure, a dual-system configuration is introduced: the grid provides stable power, while the energy storage units supply pulse power, effectively mitigating grid impact and reducing transformer capacity requirements.

How has the energy storage device impacted the fusion power supply?

The introduction of the energy storage device has effectively reduced the grid's power impact from the fusion power supply from 260 MW to below 90 MW.

How do superconducting tokamaks work?

However, contemporary fusion devices predominantly rely on superconducting coils that operate in extended pulses lasting hundreds of seconds, presenting challenges for pulsed generators to sustain prolonged discharges, leading to grid power dependency. So Superconducting tokamaks directly extract electricity from the power grid .

How to optimize energy storage capacity?

This hybrid configuration optimizes energy storage capability by leveraging the strengths of lithium-ion batteries for energy output and supercapacitors for pulse power output. To optimize the capacity configuration of the energy storage devices, a method utilizing an improve MOGWO was proposed.

What is a multielement energy storage system?

Multielement means that the topology contains multiple types of energy storage elements. In this topology, the lithium-ion batteries are deployed centrally on the bus on the secondary side of the main transformer and the supercapacitors are deployed dispersedly on the secondary side of the rectifier transformer.
