To organically configure charging facilities with different rated power, this paper proposes a siting and sizing planning method of urban EV charging station group, including multiple types of charging facilities. A cooperative service level model with multi-type charging facilities is designed in consideration of the uncertainty of EV users’ behavior and the diversity of their demand,and the intra-station charging power dispatch as well. On this basis, a cooperative planning method of charging station group with multi-type charging facilities is proposed. This model also considers comprehensive social cost, with constraints of charging demand allocation and distributed electricity network operation. The proposed optimization method can be modelled into a mixed integer second-order cone model, which could be solved effectively. In this paper, an actual urban area example, which combines geographic information with a 31-node distribution network, is used to verify the feasibility and effectiveness of the proposed method.
