Demand response capability analysis of central air conditioners based on group rotation control

Due to the rapid increase of air-conditioning load, it has become a research hotspot to reduce the peak load by carrying out demand response on the user-side. The purpose of this paper is to study the feasibility and effect of demand response regulation technology for commercial building air-conditioning load to achieve peak shaving on the power grid. Firstly, a physical model of a single central air conditioner is constructed and then the regulation capability of a single air conditioner and the group rotation control of air conditioners are evaluated. A genetic algorithm is then used to optimize the load control strategy for users to participate in demand response. Finally, a case analysis of air-conditioning load demand response based on group rotation control is given, which verifies the effectiveness of the proposed two-level group rotation control model of central air conditioner group for demand response
