The paper examines the impact of distributed generation facilities on the operating parameters of Iraq’s 33/11 kV distribution networks. The performed calculation of steady-state and post-emergency modes in the RastrWin3 software package showed that the networks are overloaded and therefore the voltage and power losses in the nodes and branches reach their limits. It was revealed that the most optimal technical measure that increases the voltage level in the load nodes and reduces power losses in the branches is the use of distributed generation, which includes diesel power plants and solar plants. The calculated operation modes considering connection of photo-diesel power stations to the network showed that the voltage and power losses in the nodes and branches of the circuit were significantly reduced
