中文摘要:
      规模化电动汽车(Electric Vehicle, EV)的无序充电行为给电网造成了压力,因此研究EV有序调度策略对保证电网的安全运行具有重要意义。为此,文中提出一种计及用户电池损耗的分布式两阶段调度策略。在调度前定性分析调度意愿和调度能力以筛选可调度车辆,并在第一阶段提出了平均充电率指标,结合最小充电成本完善用户侧优化,在第二阶段以最小峰谷差为目标对电网侧进行削峰填谷。对比不同算例场景发现,所提策略有效地降低了充电成本及电池损耗、减小了负荷峰谷差、平抑了负荷波动,兼顾了电网与EV用户双方的利益与需求。
英文摘要:
      The disorderly charging behavior of large-scale electric vehicles (EV) puts pressure on the power grid. Therefore, the orderly dispatching strategy of EV is of great significance to ensure the safe operation of the power grid. To this end, a distributed two-stage scheduling strategy that takes into account user battery consumption is proposed in this paper. Firstly, the dispatch willingness and dispatch ability are qualitatively analyzed before dispatching to screen for dispatchable vehicles. Secondly, the average charging rate index is proposed in the first stage, combined with the minimum charging cost to improve user-side optimization, and in the second stage, the minimum peak-to-valley difference is the goal peak shaving and valley filling are performed on the grid side. Finally, comparing different scenarios, it is found that the proposed strategy effectively reduces the charging cost and battery loss, reduces the load peak-to-valley difference, smoothes load fluctuations, and takes into account the interests and needs of both the power grid and EV users.
