Abstract
With the increasing popularity of electric vehicles (EVs), wide spread integration of these EVs are inevitable. The utility must be ready to integrate these EVs as customers start mass adoption. The engineering community is already worried about the increasing loading for residential feeders purely due to the increased load power of the EVs. Yet, a commonly simplified or overlooked part of the power system analysis is unbalanced current and unbalanced loads. Unfortunately, we cannot control who and when customers will purchase and charge EVs. Most likely, EVs will be popular in higher wealth neighborhood first while lower income neighborhoods might not ever purchase EVs. This will cause a load unbalance in distribution feeders. With Current's Physical Components (CPC) theory we can understand unbalance loading and quantify its detrimental effects on the power system. Given the severity of the detrimental effects, a passive compensator can be designed and installed to mitigate the unbalanced loading. This will return the feeder to a more ideal balanced system. The effectiveness and side effects of this compensator will be studied and simulated with EV chargers being placed on a distribution feeder.
