Abstract. Large-scale grid-connected distributed generation (DG) will cause out-of-limit of voltage deviation. The model of voltage drop caused by loads and voltage rise caused by distributed generators are established under different loads or DG distribution modes along the line, and the maximum allowable capacity of power injected into the grid without causing over-voltage is calculated, assuming the bus voltage deviation reaching the upper limit. The maximum DG penetration level of typical distribution lines is derived under the condition that generators is of the same distribution mode with loads, and the voltage margin at the head end of the line without causing over-voltage is proposed. The results show that over-headlines can carry much more DG power than cables, and over-voltage will be avoided by controlling the DG capacity according to the connected bus voltage, and suitably lowering the bus voltage will allow much more DG to connect into the grid.
