Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a mobile energy storage system of a lithium iron phosphate battery and a control method thereof. Background technique [0002] The energy storage system has gradually become a key device in the future new energy grid access and smart grid construction. The energy storage application of wind power generation and photovoltaic power generation systems has been applied in many demonstration projects abroad. At present, batteries that can be used as energy storage components include lithium iron phosphate batteries, NaS batteries, vanadium redox flow batteries, etc., but their technical maturity and economic efficiency have not yet met the requirements for large-scale applications. [0003] The development of the electric vehicle industry and micro-grid energy storage has promoted the industrialization of power batteries represented by lithium iron phosphate batteries, and c...
