In the new-type power system,the source,grid,load and storage sides jointly ensure safe and reliable electric supply.As an important seasonal power system load,air conditioning load management through demand response is help-ful for the grid to smoothly transit to peak loads during summer and winter seasons.Air conditioning loads of large con-sumers such as business and institutions can be used as flexible loads for network load interaction,ensuring power supply in the form of virtual power plants.Large users generally use multi-split or water-cooled air conditioning units with multi-ple and dispersed control nodes.To meet the requirements of hundreds of control nodes,an effective optimization control strategy is needed for the demand response terminal.
