Since the electricity distribution networks are designed for one-way energy flow from medium voltage to low voltage, they have become open to bidirectional energy flow with the production plants connected to the network from different voltage levels, and the changing energy flow direction has brought many integration problems, especially the disruption of the voltage regulation. It is envisaged that the integration of solar power generation facilities to the distribution network will be realized due to the fact that the “Regulation on Unlicensed Electricity Production in the Electricity Market” has entered into force and which has gained intense attention due to its ability to be installed and easily scaled in comparison to other energy sources. In this article, voltage regulation problems arising from the integration of solar power plants in the Kahramanmaraş region to the electricity distribution network here are examined. Within the scope of the study, a pilot feeder, on which a large number of solar power plants are connected, was determined and load flow analyzes on this feeder were carried out with the help of the network analysis program Digsilent Power Factory.
