Abstract In order to eliminate the doubts of grid technicians on the application of battery inverter grid-connected discharge technology in substation battery intelligent operation and maintenance, the principle of inverter grid-connected technology and the program-controlled discharge control process of substation are briefly introduced, and the battery inverter grid-connected discharge system test platform is built. The power quality of the grid-connected power is analyzed to verify that the grid indicators are all within the standard range after the grid is connected to the grid, and the power quality of the substation will not be influenced.
