Electric car technology is gaining popularity since it reduces fossil fuel use and ICE pollution. Since an electric vehicle's performance depends on a battery's limited electricity, power flow optimization is vital. Electric vehicles can backup the grid and local loads, lowering peak load and filling the valley point, thus their adoption in the distribution grid is accelerating. Software professionals choose electric cars for their environmental friendliness. Car batteries are connected to grid monitoring facilities for the company's parking garage State of Charging (SOC) charging stations. Renewable power like solar will charge batteries to 100% SOC. Overflow electricity from the PV system can be supplied to the load and grid. The vehicle's batteries will support load at a condition-based Allowable State of Charge (SOC) like a UPS. The day's battery capacity depends on the number of cars on the shift. This study suggests employing the electric vehicle's battery backup as a UPS for a software company and to boost the DVR in the case of a distribution system failure. The EV DVR automatically corrects for voltage harmonics, voltage sag-swell, and distribution system voltage disruptions, increasing the power quality of the entire EV system without additional compensation equipment. MATLAB/SIMULINK models the entire system, proving the goal is achievable.
