Reliable Aggregation Optimization Technology for Large-Scale Variable Frequency Air Conditioning Load Under Multiple Rotation Control

The difficulty of smoothing the output fluctuations of large-scale variable frequency air conditioners is affected by the power supply pressure during peak hours, resulting in low stability of variable frequency loads. In order to ensure the comfort of users' electricity consumption, a reliable aggregation optimization technology for large-scale variable frequency air conditioner loads under multiple rotation control is proposed. Set up thermodynamic models, electric thermal conversion models, and comfort models to describe individual air conditioning load characteristics, comprehensively consider the physical characteristics of air conditioning equipment, user comfort requirements, and power system scheduling needs, calculate the longest rotation period that meets temperature fluctuation requirements, solve the aggregation power expectation function based on priority, and optimize the reliable aggregation results of large-scale variable frequency air conditioning loads by combining the overall aggregation power. The experimental results show that the proposed method achieves a maximum of 1.2 or above in the load response consistency index, and the load fluctuation is effectively controlled. Optimize the load aggregation of large-scale variable frequency air conditioning to enhance the stability and operational efficiency of the power system.
