Abstract

In order to ensure safe connection of the energy storage frequency modulation system into power grid

the grid-connected test scheme for the energy storage frequency modulation system at generation-side was formulated according to the latest national standard

and field test was carried out. Based on the introduction of the measured energy storage frequency modulation system and the grid-connected performance test program

the test methods of the charge and discharge response performance

power control performance and fault ride-through performance of the energy storage frequency modulation system were elaborated

and the test results were analyzed in depth. Combined with the test data

the problems of charge-discharge response performance

power control performance and fault ride-through performance of the energy storage frequency modulation system under test were pointed out. The grid-connected test can comprehensively detect the charge and discharge response performance

power control performance

grid adaptability

fault ride-through performance

and power quality of the energy storage system

and provide data support for the safety assessment of the energy storage system's grid connection.
