Table 1 Challenges of electric vehicle integration in power quality
Challenges | Description |
|---|---|
Power losses | With a large number of unregulated and single-phase EV charging stations, power loss rises. High EV penetration causes distribution transformer losses and overloading [7,8,9,10] |
Voltage Unbalance | Single phase electric vehicle charging large load increases voltage unbalance, due to incorrect distribution of all single-phase load by three phases of system [9] |
Voltage Fluctuations | Impact increase as charging rate and penetration increases [11,12,13] |
Harmonics | Impact increase as charging rate and penetration increases also increases with random EV charging [14, 15] |
