The electrification of construction machinery has created a perceptible future trend of the development of electric construction machinery collaboration systems (ECMCSs). However, there is a lack of research on energy-efficient operation of ECMCS. This paper proposes a theoretical configuration and scheduling framework promoting the applications of ECMCSs. In the configuration stage, this paper considers the effect of charging time and proposes an electric matching factor to achieve an optimal system configuration. In the scheduling stage, a multi-objective scheduling problem is formulated for achieving energy-efficient system operation, which considers the transport volume, cost and idle time. A validation of the framework was carried out using a case study that found the optimal system solution, while the advantages of the considered ECMCS compared to a fossil fuel-powered system were discussed. The impact of battery and charging technology developments was also assessed. This framework can be widely applied to deployment of ECMCSs.

用于电动工程机械协作系统的节能配置和调度框架


工程机械的电气化为电动工程机械协作系统 （ECMCS） 的发展创造了一个可感知的未来趋势。然而，目前还缺乏对 ECMCS 节能运行的研究。该文提出了一种理论配置和调度框架，促进了 ECMCS 的应用。在配置阶段，本文考虑了充电时间的影响，并提出了电匹配因子来实现最优系统配置。在调度阶段，为实现节能系统运行，制定了多目标调度问题，考虑了运输量、成本和空闲时间。使用找到最佳系统解决方案的案例研究对框架进行了验证，同时讨论了所考虑的 ECMCS 与化石燃料动力系统相比的优势。还评估了电池和充电技术发展的影响。该框架可广泛应用于 ECMCS 的部署。
