A Two Stage Model for Optimum Allocation of Electric Vehicle Parking Lots in Smart Grids

In this paper, a model is presented to recognize the optimum site and size of the electric vehicle (EV) parking lots providing vehicle to grid (V2G) power injection in power distribution system. The allocation problem has been modeled by a two-stage modeling approach. It optimizes the siting and sizing of parking lots for minimizing the planning and operational costs and maximizing revenues. In the first stage, electrical power losses, investment cost, revenue obtained from V2G power and that obtained from charging EVs for driving are considered as components of the objective function. The output power of parking lots is computed in the second stage. The proposed method is evaluated through numerical studies. The results show that optimum planning of EV parking lots have economic profit for both power distribution companies and parking lot owners.
