Problems solved by technology

However, the current all-vanadium redox flow battery technology is not mature enough, and there are many problems
The remarkable feature of the flow battery system and other non-flow battery systems is that the flow battery needs to use the magnetic force to drive the circulation pump to provide power for the circulation of its liquid circuit system. The driving circulation pump cannot work, and the fluid circulation cannot be restored, which leads to the inability to start the all-vanadium battery system (that is, the inability to black start)

Description

[0001] Technical field: [0002] The invention relates to the field of liquid flow battery energy storage, in particular to a black start system of a liquid flow battery energy storage system and a control method thereof. [0003] Background technique: [0004] Liquid flow battery is one of the excellent green batteries with strong development momentum at present. It has obvious advantages such as high power, long life, and deep and high current density charging and discharging. It has become one of the main commercial development directions in the battery system. In wind power , photovoltaic power generation, power grid peak regulation and other fields have extremely broad application prospects. However, the current all-vanadium redox flow battery technology is not mature enough, and there are many problems. The remarkable feature of the flow battery system and other non-flow battery systems is that the flow battery needs to use the magnetic force to drive the circulation pum...
