With the increasing integration of renewable energy sources

the safe and stable operation of the power grid faces significant challenges.When issues such as active power deficits arise

the precision of power control and response time of renewable energy stations do not meet requirements

hindering their ability to quickly participate in peak shaving and regulate voltage and frequency within the grid.This paper elaborates on the testing methods for connecting electrochemical energy storage stations to the power grid.It addresses issues such as inappropriate communication configurations and unreasonable software logic during testing

proposing corresponding optimization measures like "stop upon reaching limits." Validation of these measures shows that the proposed series of testing optimizations can effectively resolve problems related to excessive response times and inadequate power regulation during testing

significantly enhancing the efficiency of testing for energy storage stations connected to the power grid.
