美国电力需求侧调频实践及其对我国的启示

Frequency Regulation Practice at Demand Side in USA and Its Enlightenment to China

近年来,在美国出现了应用需求侧电力资源进行电网AGC调频的新技术。本文系统地分析了需求侧调频的概念、可用于调频的负荷类型及特性、需求侧调频对各个环节的关键技术要求和商业模式等。最后,结合中国电力辅助服务市场的发展情况,提出了需求侧调频的推广建议。

In recent years, a new technology of AGC fre- quency regulating for power grid by applying power resource at demand side is proposed in the United State. In this pa- per, concept of frequency regulation at demand side, load category and its characteristic applied in frequency regula- tion, key technology requirements of each link needed in fre- quency regulation and commercial modes are systematically ana- lyzed. In the end, promotion suggestions on frequency regula- tion at demand side are proposed by combining with the devel- opment of power ancillary service market in China.
