Abstract

The invention discloses an electric vehicle charging and discharging scheduling method and system. A fuzzy algorithm is introduced, and the optimal particle deviation is used as a reference quantity to adjust an inertia weight parameter in the particle swarm algorithm; the self-selection link in the particle updating process is optimized; and the position and speed of each particle are updated again by using the adjusted inertia weight, a Logistic mapping structure chaotic sequence is introduced to carry out chaotic optimization on the overall optimal position of the particle swarm, the motiontrack of the optimal particle is changed, and an obtained new optimal solution is used as a charging and discharging time sequence scheme of the electric vehicle.

Description

technical field [0001] The present disclosure relates to a charging and discharging scheduling method and system for an electric vehicle. Background technique [0002] With the increase of the number of electric vehicles, the disorderly connection of large-scale electric vehicles to the power grid in time and space is bound to have an impact on the original power grid system. As a special mobile energy storage unit, if electric vehicles can be connected to the power grid in an orderly manner, power supply can be performed when the power grid load curve is low, and it can be used as a controllable power supply to feed power to the power grid during peak power consumption. To achieve a win-win situation for users and the grid. Therefore, research on reasonable charging and discharging strategies for electric vehicles is necessary. [0003] The orderly charging and discharging (V2G) problem of electric vehicles is usually transformed into a given power consumption range and t...
