Optimizing Energy Efficiency and Grid Stability via Public EV Charging Flexibility
- 利用真实充电数据，动态调整充电时段以匹配低需求高可再生能源期。
- 可显著减少能源浪费和电网不平衡，降低对辅助服务依赖。
- 适合电网运营商与充电桩管理者参考，助力绿色能源融合。
本研究评估了公共电动汽车（EV）充电灵活性在提升能源效率和电力系统稳定性方面的潜力。基于布拉格公共充电站的真实数据，分析个体及聚合充电行为，探索优化充电时间对减少能源浪费、降低电网失衡以及促进可再生能源整合的作用。通过将充电活动与电网负荷较低、可再生能源发电量较高的时段对齐，显著提升了能源利用效率，减少了对昂贵系统支持和辅助服务的需求。研究结果表明，配电公司与输电系统运营商之间的协作，可在日益不确定的能源环境中，为维持电网稳定和推动可持续能源使用创造新机遇。
原文摘要 · Abstract (English)
This study evaluates the potential of electric vehicle (EV) charging flexibility to enhance both energy efficiency and power grid stability. Using real-world data from public charging stations in Prague, we analyze individual and aggregated charging sessions to explore how optimizing charging times can reduce energy waste, minimize grid imbalances, and support the integration of renewable energy. By aligning EV charging with periods of lower grid demand and higher renewable generation, we demonstrate a significant improvement in energy efficiency, reduc ing the need for costly system support and ancillary services. Our findings suggest that cooperation between power distributors and transmission system operators can unlock new opportunities for maintaining grid stability while promoting sustainable energy use in an increasingly uncertain energy landscape.
