Problems solved by technology

However, the existing research on the scheduling of electric vehicles does not consider both the loss of the battery caused by the large amount of charging of the electric vehicle and the voltage drop caused by the distribution network. Overcharging will affect the performance of the battery cycle life and electrode side reactions. It will also affect the voltage level of the distribution network, which is not conducive to the development of the distribution network

Abstract

The invention discloses an electric automobile optimization scheduling method based on an alternating direction multiplier method and belongs to the field of electric automobile optimization scheduling. The achievement method comprises the following steps of: firstly, establishing an electric automobile charging model considering the feeder capacity constraint of a power distribution network; secondly, establishing a charging scheduling optimization problem considering the feeder capacity constraint; and finally, solving the charging scheduling optimization problem by utilizing an electric automobile optimization scheduling method based on an alternating direction multiplier method to obtain an electric automobile optimal charging scheme, wherein the electric automobile optimal charging scheme cannot influence the voltage level of the power distribution network under the consideration of the benefit of the electric automobile, and peak clipping and valley filling can be achieved through reasonable scheduling of the electric automobile, so that the balanced development of the electric automobile and the power grid is facilitated. The balanced development means that: (1) the loss ofbatteries caused by mass charging of the electric automobile can be reduced; (2) voltage drop of the distribution network caused by mass charging of the electric automobile is avoided.

Description

technical field [0001] The invention belongs to the field of optimal scheduling of electric vehicles, and in particular relates to an optimal scheduling method of electric vehicles based on Alternating Direction Method of Multipliers (ADMM). Background technique [0002] The increase in power demand and the shortage of traditional fossil energy have all prompted the development of the power grid in the direction of intelligence, efficiency and sustainability. Different from the traditional distribution network, the existing active distribution network can actively manage distributed power sources and flexible loads. The continuous growth of flexible loads represented by electric vehicles has brought great challenges to the voltage level, power supply reliability, and power quality of the distribution network. [0003] However, under the control of the incentive mechanism, electric vehicles are very flexible. Through optimal scheduling, peak load shifting and valley filling ...
