Distance protection is considered important and essential in power systems. Due to the development of distribution systems and the system's topology change from time to time, integrating electric vehicles into the distribution system leads to an increase in short circuit level and injection of harmonics into the system. Since the vehicles are continuously variable loads, this leads to difficulty in adjusting the protections that depend on the current in the process of adjusting them. As a result, distance protection is used in distribution systems. This paper shows the effect of integrating electric vehicle charging stations on the relay performance of distance protection in the distribution system. Distance protection relay was built based on artificial neural networks adapted to the system conditions. The accuracy of the neural network model used for fault detection was (99.9%), and the error rate in locating the fault was (0.00079%).
