Abstract

The invention provides an electric vehicle charging time sequence determining and service vehicle selecting method for participating in frequency modulation services. The method comprises inputting electrovalence information and vehicle information into a charging device; obtaining the required charging time according to initial electric quantity level, target electric quantity level and the maximum average charging rate of vehicles; obtaining vehicle parking time and possible charging time sequences of the vehicles according to turn-on time and departure time of the vehicles; calculating vehicle earnings under each charging time sequence according to a vehicle earning formula, and determining the time sequences for enabling the earnings to be maximum; determining charging time sequences after the vehicles respond to scheduling instructions; and enabling the charged vehicles to be evaluated at a charging place, and selecting service vehicles from small to large according to evaluation indexes. According to an embodiment, the vehicle charging benefit is effectively improved, the peak valley load difference of a power distribution network is reduced, and the frequency modulation service capacity is increased.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method for determining the charging sequence of an electric vehicle participating in frequency modulation services and selecting a service vehicle.
