电动汽车（EV）在世界各地的普及为建立可持续的城市和交通系统带来了挑战和机遇。工作场所充电设施的双向充电能力（例如，作为微电网的一部分）一方面使得整体经济优化更具吸引力，但另一方面也更加复杂。本文研究了连接到两个不同建筑物的工作场所微电网双向充电的成本优化问题，以确定重型和轻型电动汽车（HDEV和LDEV）组合的最佳框架。开发了一个基于深度学习的模型来预测15分钟的太阳能发电量和建筑能耗。实时行程数据已被用来表示电动汽车充电的时间不确定性。成本优化问题被制定为一个混合可编程（MIP）模型，也解决了电池寿命退化。此外，已经进行了全面的经济分析，以分析投资回收期，峰值降低，并在同一工作场所的两个不同的建筑物与车载和非车载充电器配置的成本节约。已经发现，与LDEV相比，HDEV在能源成本降低和投资回收期方面是更好的成本效益解决方案。在大多数情况下，净计量能力可实现更高的节能和峰值降低。
The proliferation of electric vehicles (EVs) all around the world offers both challenges and opportunities to build a sustainable city and transportation system. Bidirectional charging capabilities at workplace charging facilities (e.g., as part of a microgrid) have made the overall economic optimization more attractive on one hand, but also more complex on the other hand. This paper investigates the cost optimization problem for bidirectional charging at a workplace microgrid connected to two different buildings to determine the optimal framework for a combination of both heavy-duty and light-duty electric vehicles (HDEV and LDEV). A deep learning-based model has been developed to forecast the 15-minute solar generation and building power consumption. Real-time travel profile data has been used to represent the temporal uncertainty of electric vehicle charging. The cost optimization problem is formulated as a Mixed Integer Programming (MIP) model which also addresses battery life degradation. Furthermore, a comprehensive economic analysis has been carried out to analyze the payback period, peak reduction, and cost savings for two different buildings at the same workplace with both on-board and off-board charger configurations. It has been found that HDEV is a better cost-effective solution in comparison to LDEV in terms of energy cost reduction and payback periods. Net metering capability leads to higher energy savings and peak reductions in most cases.
