Utility losses due to electric vehicle charging

The increasing presence of nonlinear loads in modern power systems has significantly changed energy consumption patterns. As these loads increase, active power becomes less dominant in the overall power delivery, leading to a greater dominance of reactive and distortion power components. Since utility mainly measures active power/energy, unaccounted losses result in grid inefficiency. This paper will focus on the losses introduced by electric vehicle chargers due to their nonlinear characteristics. The impact of reactive and distortion power on overall energy losses will be highlighted, emphasizing the need for improved measurement techniques and loss reduction strategies to enhance power system efficiency.
