中文摘要

为应对全球气候危机,发展可再生能源发电至关重要,但分布式电源的接入引发电压波动与弃电问题。本文提出一种电动汽车聚合商调度策略,通过基于节点边际电价动态调整充电费用,引导电动汽车在不同充电站错峰充电,从而减少光伏弃电并提升电网稳定性。利用多智能体交通仿真工具MATSim生成美国科罗拉多州丹佛市的电动汽车行驶数据,并在含分布式能源与充电站的IEEE 33节点系统上进行仿真验证。结果表明,该策略可有效降低光伏弃电率12.55%,并改善电网运行稳定性。

English 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.
