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.
