چکیده: Abstract: In this thesis, a novel method for the intelligent scheduling of charging and discharging of electric vehicles (EVs) is proposed, considering their load response capability. To this end, a conceptual framework for an optimal energy management system, along with its governing rules, is first introduced for use in EV parking lots. Additionally, the financial interactions between the parking lot operator, the distribution network operator, and EV owners are clarified. Furthermore, an optimal charging and discharging scheduling approach for EVs is presented to eliminate the dependency of planners on heuristic optimization algorithms. Meeting the expectations of EV owners is addressed by considering penalties for lost opportunity costs and penalties due to the failure to provide the desired charge level for EVs upon leaving the parking lot. To make the modeling of the optimal charging and discharging scheduling problem more realistic, uncertain parameters are modeled using a point estimation method. The proposed method is capable of optimally scheduling the charging and discharging of EVs and their participation in demand response programs, maximizing the profits of both the network operator and EV owners. According to the proposed model, in a charging station with specified demand and capacity for participation in demand response programs, an increase in the number of EVs does not necessarily lead to an increase in the charging station operator’s profit. Moreover, if the number of EVs entering a charging station exceeds its allowable capacity, one of the following two scenarios occurs: First, the charging station may fail to provide the desired charge for some customers, in which case it must pay penalties to EV owners for not meeting their desired final charge level. Second, by shifting the charging and discharging schedules of other EVs, the station may accommodate the excess EVs to achieve their desired final charge level. However, in this case, the station must compensate other EVs for the lost opportunity to generate higher profits. Consequently, in both scenarios, the parking lot’s profit will decrease.
