| description | A method for grid support by means of an inverter is disclosed, wherein the grid is supported by feeding in compensation currents. The method includes measuring a prevailing grid state, and breaking down voltages measured for measuring the prevailing grid state into symmetrical components of the grid state including positive sequence system components and negative sequence system components. The method further includes determining symmetrical components of a compensation current including positive sequence system components and negative sequence system components of the compensation current as functions of deviations of the positive sequence system components and negative sequence system components of the grid state from reference values, and feeding-in a compensation current as the vector sum of the determined symmetrical components of the compensation current. |
