We will take a closer look at the 600KW/1.2MWh distributed energy storage project in Hangzhou, China. This project represents a successful example of advanced energy storage technology in action, aiming to improve the flexibility and reliability of energy use through efficient power storage and management. We will introduce the project's design concept, implementation process, and key technologies used to demonstrate its importance in coping with fluctuations in power demand and supporting the integration of renewable energy sources.
