In this paper,grid connection test technology of electrochemical energy storage system is deeply studied,and relevant tests are carried out for storage station's grid-connection with respect to charge-discharge response time,adjust-ment time,and charge-discharge conversion time.First hardware circuit design and software design of the system are out-lined,and then power control capability,charge-discharge response time,charge-discharge adjustment time,and charge-discharge conversion time of electrochemical storage station are tested respectively.Correlation analysis of the test results indicates that measurement deviation and measurement accuracy of power control capability meet the requirements of na-tional standard,which verifies the feasibility of the proposed test scheme for grid-connection characteristics of energy stor-age facilities.
