The misalignment in the objective of network operators and commercial market parties has created prominent impacts from different perspectives and revealed that a charging strategy to minimize peak load eliminates the need for grid reinforcement and enables better grid utilization .
Several challenges have hindered the increasing use of electric vehicles, including range anxiety, slow charging times, higher Vehicle costs, a shortage of infrastructure for charging, and battery degradation. Unlike internal combustion engine (ICE) vehicles that can refuel in a few minutes, charging EVs takes longer.
A key characteristic is ensuring power quality and grid stability. This involves maintaining voltage stability, minimizing voltage deviations and power losses, managing reactive power, and addressing the effect of renewable energy integration and EV charging on grid stability and power quality.
The variation in the charging capacity of a battery affects the charging circuit by causing changes in the load, which in turn results in an increase in the magnitude of current drawn from the power grid.
While previous studies , , , , , , , , have primarily investigated the effects of EV charging and discharging on the grid, the specific impact of fluctuating EV loads has not been thoroughly quantified or analyzed.
