Optimal Charge-Discharge Scheduling of Electric Vehicles Considering Their Battery Lifetime

Electric vehicles are increasingly became appear in power systems. Optimal scheduling of electric vehicles including the amount and the duration of charging and discharging their batteries can bring great benefits to power systems. By charging in low electricity price periods and discharging in high electricity price periods, energy prices in the whole power system can be more balanced. Furthermore it can help power system to meet electricity demand in high demand periods. However, when a large population of electric vehicles are considered, many practical factors including battery lifetimes could be effective on optimal scheduling of them. In this paper, a new formulation for optimal scheduling of electric vehicles in a real power system structure considering battery lifetime constraints is introduced and the results are compared with the case that these constraints are not included.
