The Research on Siting and Sizing of Electric Vehicle Charging Stations Based on Two Stage Optimization

摘要

To meet the charging demand of the electric vehicles (EVs), a new two stage optimization (TSO) method is proposed in this paper with the consideration of the public service attributes of EV charging station (CS) and its impact on the distribution network. First, the locating and sizing scheme based on the multi-level capacity of CS is presented according to EV charging demand. Next, the optimal method of CS connected to the grid is derived from the point of view of the distribution network. Then, Mixed Integer Programming (MIP) and Improved Cuckoo Search (ICS) algorithm are sequentially applied to solve above optimization problem. Finally, experimental results manifest that the proposed model and algorithm are practical, useful and feasible.
