Optimal configuration of distributed generation and EVs charging piles under EVs’ reserved charging mode

With the explosive growth of the number of electric vehicles (EVs), a reserved charging mode of EVs is designed to meet the autonomy of the charging demand. Meanwhile, an optimal configuration of EVs charging piles is proposed to meet the diversity of the charging demand, with optimal combination of distributed generations (DGs). The mathematical model is then constructed and solved by the second-order cone relaxation (SOCR) method, which can be converted into a mixed-integer second-order cone relaxation model. Finally, taking the actual geographical information in Hangzhou city as an example, the simulation is coupled with the IEEE 33-nodes distribution network to verify the rationality and effectiveness of this constructed model.
