Mitigation of Power Quality Issues during Electric Vehicle Integration

Transportation system is considered as the second largest source of carbon emissions after power generation. EVs (Electric Vehicles) play major role in reducing carbon emissions. Integration of EVs into the grid not only reduces carbon emissions but also protects environment. However there exists, many challenges during this integration. The major challenges faced during integration are overloading of power grid, power quality (PQ) issues, supply demand imbalance, increased peak demand, frequency deviation, energy losses, reduced stability and reliability, battery degradation and high investment cost. In this regard, few concerned issues from the above are considered and they are being mitigated by using RES as the main power supply. When these sources are unable to provide sufficient power to charge the vehicles, we rely on the energy stored in BESS for vehicle charging. In this event that BESS is also incapable of meeting the power demand, the Grid serves as an alternative power source for vehicle charging. This mitigation technique is being discussed and demonstrated using the MATLAB Simulink platform.
