Charging Control Scheme for Electric Vehicles Based on Consumer Psychology

With a large number of electric vehicles connected to the grid, the orderly charging problem of electric vehicles has attracted more and more attention. The present techniques control charging load of electric vehicles mostly from the perspective of centralized control, but few reports the charging model based on consumer psychology. Based on the study of the traffic travel regularity of residents, this paper establishes consumer psychology model of the charging load influenced by the electricity price. The response of the charging load to the electricity price is described by the load shifting rate. Through the optimization of peak-valley time of use power price, the peak load shifting and load curve optimization can be achieved. Finally, testing results verify the effectiveness of the proposed method.
