Summary:

Changes in energy demand in the power grid occur at predictable reasonable levels for

system operators. With electric vehicles reaching significant number of parks in

transportation, System operators must change their predictions and revise planned

investments. A distribution system integrated with electric car charging stations was

modeled in Trabzon to determine the number of electrical vehicles for the region according

to the countrys goals and policies, and to detect and minimize system requirements early.

In the study, the distribution system, which serves the 40% population of Trabzon, was

modeled. The base year for the distribution system was set and the load increase forecasts

were included in the system for years, regardless of the number of electric vehicles. The

development of the number of park of electric vehicles in the city was determined by

mathematical expressions in accordance with the countrys goals and policies. Depending on

the number of electric vehicles, energy demands from charging units were integrated into

the distribution system in accordance with the standards. Modeling and calculations were

carried out in Digsilent Power Factory. How effect to load flow in distribution system was

determined examining voltage losses and line loading because of electric vehicles

development and charging stations.
