Abstract—There are two ways to distribute electric energy to customers: overhead lines and underground cables. Overhead lines and underground cables have different electrical characteristics. Underground cables have less resistance and inductance compared to overhead lines. Also, underground cables have more capacitance than overhead lines. This paper will test the voltage response of the system when electric vehicles are charged from overhead and underground distribution systems. The test will be done using IEEE 34 bus test feeder for the overhead distribution system. For the underground system, all overhead lines in IEEE 34 bus test feeder will be replaced with underground cables following the same electrical configuration.
Index Terms—Electric vehicles, IEEE 34, voltage violation, power distribution.
