In the context of global energy transformation

the reliability and economy of distributed energy access to the power grid have become key issues. As an innovative power electronic device

uninterruptible power connection equipment (UPC) realizes efficient and stable energy flow between distributed energy and the power grid through the integrated energy storage system

power electronic converter

intelligent control system and other key technologies. This study explores the of application effect of UPC's working principle

control strategy

fault handling mechanism

etc. in engineering

puts forward a new access mode and optimized operation strategy based on predictive control

and combine the Internet of Things and big data technology to achieve intelligent monitoring. UPC plays a significant role in improving the reliability of distributed energy access to the power grid

promoting the optimization of energy structure and ensuring the safe operation of the power system.
