计及电池动态损耗的电动汽车有序充放电策略优化
Orderly Charging and Discharging Strategy Optimization for Electric Vehicles Considering Dynamic Battery-wear Model
摘要
Abstract
When electric vehicles (EVs) discharge to the grid through vehicle-to-grid (V2G) technology,existing models for calculating battery wear are too simple to accurately reflect the battery wear.Therefore,a dynamic capacity fading model for battery discharge is used based on the battery discharge characteristics.Then the conclusion that battery wear differs a great deal when the battery releases the same amount of power under different SOCs is drawn.Taking the capacity constraints of distribution transformers into account,a model minimizing the charge-discharge fee of orderly electricity users is developed,as is the corresponding charge and discharge policy.In order to solve the model,the priority list method is adopted to transform the multi-period optimization problem into an optimization problem of each period.The results show that the method is effective not only for protecting the interests of discharging users,but also for increasing the profits of charging stations and the success rate of disorderly charging users.关键词
