Abstract

The global climate crisis demands urgent action to mitigate global warming. Using renewable energy sources, such as solar and wind power, for electricity generation is crucial. This shift from centralized to distributed power systems, however, brings challenges, including voltage fluctuations and renewable energy curtailment. The rapid growth of the electric vehicle (EV) industry adds complexity, increasing overall electricity demand and straining the power supply during peak charging times. This paper proposes a scheduling strategy for EV aggregators to reduce renewable energy curtailment and stabilize grid operation by strategically scheduling EV charging. Using Multi -Agent Transport Simulation (MATSim), a traffic simulation tool, EV driving data in Denver, Colorado, USA, were modeled. The EV aggregator adjusts charging fees based on locational marginal prices, encouraging EVs to charge at different stations according to pricing. Simulations on an IEEE 33-bus system with distributed energy resources and EV charging stations validate the proposed algorithm, demonstrating its effectiveness in reducing curtailment by 12.55% and stabilizing grid operation.

基于位置边际价格的光伏弃风最小化电动汽车集成商定价策略

全球气候危机要求采取紧急行动减缓全球变暖。利用太阳能和风能等可再生能源发电至关重要。然而，这种从集中式到分布式电力系统的转变带来了挑战，包括电压波动和可再生能源的削减。电动汽车（EV）行业的快速发展增加了复杂性，增加了总体电力需求，并在充电高峰时段使电力供应紧张。本文提出了一种电动汽车聚合器调度策略，通过对电动汽车充电进行战略性调度，减少可再生能源弃电，稳定电网运行。利用交通仿真工具MATSim (Multi -Agent Transport Simulation)，对美国科罗拉多州丹佛市的电动汽车驾驶数据进行建模。电动汽车聚合器根据位置边际价格调整充电费用，鼓励电动汽车根据定价在不同的充电站充电。在具有分布式能源和电动汽车充电站的IEEE 33总线系统上进行了仿真，验证了该算法的有效性，减少了12.55%的弃电，稳定了电网运行。

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
