| 摘要: |
| 多种异质调频资源协调配合、发挥各自优势是新型电力系统调频的关键。西北电网在国内较早开始了新能源一次调频工作，并探索多类型主体协调配合的调频体系。在总结西北电网现有调频工作的基础上，进一步详细梳理了新能源、储能等新型调频资源的特点，分析了现有调频体系中不适应新型调频资源特性的地方。一次调频方面，设置不同的调频死区实现多类型资源的协调配合；二次调频方面，让响应较慢的调频资源参与二次调频，预留快速调频资源容量参与一次调频；频率安全防线方面，采用“以调代切”以及响应触发、分散控制的方式，使新型调频资源参与频率安全防线。未来将根据西北电网实际需求，逐步完善实施相关技术，构建适应新型调频资源特性的调频体系。 |

| Abstract: |
| The key to the frequency regulation of new power system is to coordinate and cooperate with va-rious heterogeneous frequency regulation resources, and to leverage their respective advantages. Northwest Power Grid started the primary frequency regulation of new energy earlier in China and explored a frequency regulation system with coordinated cooperation among multiple types of entities. On the basis of summari-zing the existing frequency regulation work of the Northwest Power Grid, the characteristics of new frequency regulation resources such as new energy and energy storage are presented, the inadaptability of the existing frequency regulation system to the characteristics of new frequency regulation resources is analyzed. For primary frequency regulation, different frequency regulation dead zones are set to achieve coordination and cooperation of multiple types resources. For secondary frequency modulation, slower response frequency modulation resources are allowed to participate in secondary frequency modulation and reserve fast frequency modulation resource capacity to participate in primary frequency modulation. In terms of frequency safety defense,“modulation instead of switching”,response triggering and decentralized control methods are adopted to involve new frequency modulation resources in the frequency safety defense. In the future, according to the actual demand of Northwest Power Grid, relevant technologies will be incrementally improved and implemented to construct a frequency regulation system that adapts to the characteristics of new frequency regulation resources. |
