The demand side comprises of different types of load: residential, commercial, and industrial. The connected loads are vulnerable to power quality changes. The power quality parameters are defined based on voltage and frequency changes and the harmonics in the power supply [31, 36, 37]. With the integration of renewables and EVs in the system, a balance in the whole power system’s flow is achieved. Balance reduces voltage surges caused due to surplus power during off-peak load hours and uncoordinated addition of renewables or energy storage. Voltage flickers that damage various equipment, especially in the residential sector, are smoothed. The harmonics are reduced with added control and optimization techniques for smart charging. Power flow management and distribution constrains the phase imbalance on the demand side [38, 39]. Thus, consumers’ reliability, on the demand side, is weighted with loads of added benefits from smart charging.
