In this thesis, the performance of charger controllers of an administrative building are being studied in order to minimize the operational cost of the building. While the entrance time of the cars and their battery state of charge (SOC) are not clear, a two-stage program is presented in order to minimize the extra costs resulted from false predictions of power. In this program, the building is connected to grid and uses PVs in addition to supply the needed power. On the other hand, V2G ability of EVs are used in order to optimize the power of the system. With the use of above solutions, the power consumption of the system is bought from day ahead market, and reprogramming is required on the day of operation in order to calculate and supply the unpredicted needed power and the extra bought power with the consideration of TOU and cancelation penalties of the previously bought power. In the following, according to charge and discharge of the battery which effects its life, the battery aging cost is evaluated and added to the whole costs of operation with a practical method. The results of this programming are comprised in four different situation: charging without control, controlled charging with and without V2G, and considering aging costs. As a result of these simulations, total cost of operation with the consideration of battery aging cost is a little bit more than not considering them; which of course considering the aging cost will increase the operation costs, but is essential for reaching the actual costs of system while the benefits of EV owners wouldn’t be in risk.
