中文摘要:

      随着我国能源结构的低碳化转型，电网调峰需求日益增长，如何有效利用定频空调负荷群参与调峰成为一大研究热点。主要探讨了定频空调负荷群在电网调峰中的协调控制方法，首先，基于定频空调负荷的功率模型，对传统优先序列调控策略进行了深入改进，进而提出了一种结合启动与切断时间的优化调控技术。在此基础上，针对空调负荷调控的响应及恢复特性，制订了一套完善的开关控制协调策略。最后，通过详实的实证分析，证明了在追求最小总负荷或最大削减量的目标下，提出的优化策略均具有显著的效益。

英文摘要:

      With the low-carbon transformation of China’s energy structure, the demand for peak shaving in the power grid is increasing day by day. How to effectively utilize the fixed frequency air conditioning load group to participate in peak shaving has become a major research hotspot. The coordinated control method of fixed frequency air conditioning load group in power grid peak shaving is mainly explored. Firstly, based on the power model of fixed frequency air conditioning load, the traditional priority sequence control strategy has been deeply improved, and an optimized control technology combining start and cut off time has been proposed. On this basis, a comprehensive switch control coordination strategy has been developed for the response and recovery characteristics of air conditioning load regulation. Through detailed empirical analysis, it has been proven that the proposed optimization strategies have significant benefits in pursuing the goals of minimum total load or maximum reduction.
