Simulation of harmonics produced by electroliners in the electrical network of Cuenca City

This article presents the simulation and harmonic analysis of a charging station model developed in “Modeling and protection of electric vehicle charging station”, which was adapted with the electrical parameters of the distribution system of Cuenca city, with The purpose of quantifying the amount of harmonics that this type of stations can produce in the network. The simulation resulted, that the fifth harmonic located at 300 Hz is the most critical in both the voltage and the current. The harmonics produced in the voltage are 15, 74% that are above the limits established in the IEEE 519-2014 standard and the Ecuadorian regulation No. CONELEC-004/01, the harmonics produced in the current are of the order of 1.54% that is within the parameters of the IEEE 519-2014 standard. The results of this research can be used to mitigate the impact and can be used by designers and builders of charging stations and for energy distribution companies.
