The study in [ 80 ] assessed the impact of uncontrolled EV charging on power losses at different daily durations. Large increases in power losses were observed, particularly during peak charging periods. The study proposed stochastic programming strategies to minimize these power losses.
EV chargers, due to the use of power electronic devices, can negatively impact power quality when integrating high numbers of Electric Vehicles (EVs) into the power network. The chargers inject harmonics into the power grid, which can lead to negative effects on electric power system components designed for pure sinusoidal waveforms and increase system losses.
