What are the grid-related tests for energy storage systems?

Sub-frequency modulation test, inertial support test, etc. The grid-connected test and modeling of energy storage system are divided into two parts: grid-connected test and grid-connected modeling of energy storage power stations. The grid-connected test of energy storage power station includes frequency modulation test, inertial support test, AGC test, AVC test and SVG performance test. Energy storage refers to the process of storing energy through media or equipment and releasing it when needed.
