提供辅助服务的高耗能产业：热镀锌工艺的真实案例
Energy-Intensive Industries Providing Ancillary Services: A Real Case of Zinc Galvanizing Process
AI总结：
本研究以丹麦热镀锌工艺为真实案例，验证高耗能产业通过适度投资熔炉功率控制可提供FCR和mFRR两类电网辅助服务，两类服务经济价值可观、投资回收期或不足一年，其中FCR对锌温影响极小更优。
摘要：
高耗能产业可通过调整用能助力电网平衡。我们以丹麦某热镀锌工艺的真实案例开展研究，展示了对熔炉功率控制进行适度投资后，即可提供多种辅助服务。我们研究了两类服务，分别是频率 containment 储备（FCR，频率 containment 储备）和手动频率恢复储备（mFRR），经数值计算得出两类服务的经济价值均十分可观，投资回收期有望在一年以内。其中提供FCR服务更具优势，因为它对锌液温度的影响可忽略不计。
英文摘要：
Energy-intensive industries can adapt to help balance the power grid. By using a real-world case study of a zinc galvanizing process in Denmark, we show how a modest investment in power control of the furnace enables the provision of various ancillary services. We consider two types of services, namely frequency containment reserve (FCR) and manual frequency restoration reserve (mFRR), and numerically conclude that the monetary value of both services is significant, such that the pay-back time of investment is potentially within a year. The FCR service provision is more preferable as its impact on the temperature of the zinc is negligible.
