AbstractThis paper aims to evaluate the effectiveness of four techniques applied to the inverter of electric vehicles for the mitigation of undervoltage occurrences due to the charging of electric vehicles in a low voltage network. The techniques employed are: Volt-Var control, Volt-Watt control, controlled recharge strategy, and the combination of controlled recharge and Volt-Var control. The simulations were conducted in a real system located in the southern region of Brazil, using OpenDSS and MATLAB software. The results show that the Volt-Var control exerts less influence on voltage control, but the controlled recharge together with the Volt-Var control proved to be more effective for this purpose.
