Electrical vehicles (EVs) are the main components of future distribution networks (FDNs). Proper operation of distribution networks in the presence of EVs, demand response programs, and distributed energy resources has attracted more attention during recent years. In this chapter a proper framework is presented for optimal day-ahead scheduling (ODAS) of FDNs, which the goal is minimizing operational costs. The proposed method determines the hourly interaction with upstream-grid, the production amount of renewable and conventional sources and charging/discharging schedule of EVs. The results show that through the proposed ODAS method, technical and security constraints of FDNs as well as economic goals of distribution network are satisfied. In addition, in this chapter EVs participated in supplying the required energy of FDNs and their effectiveness in short-term operational costs is analyzed utilizing an IEEE 33 bus test system with an urban parking lot with 10 EVs.
