The paper aims to present the impact of renewable sources operation on the power distribution network. Different aspects are tackled for the case in point. One of the discussed problems regards their influence on the voltage in network buses and power flow on the distribution system branches. Thus, power flow studies have been performed. The case study refers to a real and complex distribution system. It is managed by an important distribution system operator (DSO). It has been modelled using computer aided power system associated data collected from the DSO. In the following, the power system is modelled and the base case operating condition is computed using AC power flow methods. The information regarding the renewable source type, location and size have been provided by the DSO. All the data are incorporated into the electrical distribution network model and analyzes are performed. Another problem tackled by the authors refers to the influence of the renewable sources operation on the technical losses. Currently, in our country, the DSOs are requested (by the Energy Regulatory Authority) to assess their technical losses considering the renewable sources’ operation. Thus, a methodology is presented for this purpose.
