With the widespread use of air conditioning in various buildings, air conditioning load has become an important factor affecting the stable operation of regional power grids. If air conditioning load is not regulated, it will affect the normal electricity consumption of the entire area. Based on this, this study proposes an adaptive fuzzy PI three-closed-loop control strategy based on the framework of layered regulation of air-conditioning load areas. The method combines air-conditioning load information and fuzzy control, and flexibly regulates air-conditioning loads by forming a three-closed-loop PI control, and establishes a simulation model to verify the feasibility of the strategy. The simulation results show that the control accuracy of the control method can reach nearly 99%, which provides a new method for precise load control. The control strategy has been applied in a university, providing theoretical support and practical reference for the future promotion of flexible control technology.

Key words: air conditioning load, fuzzy adaptive control, three-closed-loop PI control, flexible control, demand response
