Abstract
AbstractThe use of electric vehicles (EVs) is becoming more common in the world. Since these vehicles are equipped with large battery capacity, they can be used as energy provider when they are parked and have enough charge level. This study investigates the possibility of Vehicle to Home (V2H) concept using EV as energy provider for a residential house in Istanbul, Turkey. High resolution residential electrical demand data is obtained to characterize the residential demand. Then, case studies are completed in MATLAB/Simulink to evaluate the cost reduction in residential electricity bill when the EV is used to supply the residential demand at peak times. It is assumed that the EV will be fully charged at off-peak hours when the energy cost is lower. Savings are calculated by finding the difference between residential electricity cost at peak times and EV charging cost at off-peak hours. Results will provide more realistic prediction of cost savings since residential demand dynamics are taken into account. In addition, the advantages of shifting peak demand to off-peak hours through the use of EV for existing grid infrastructure is discussed in terms of reduced losses and increased transmission capability.Keywords:Vehicle to home (V2H)Electric vehicleDemand managementCost analysis
