Central air-conditioning load of public buildings has become one of the most important peak load shifting resources by electric power company

for the features of using time concentration

large capacity

various adjustable methods and little influence on customer

and so on.The compose of central air-conditioning power comsumption is analyzed firstly

and the adjustable stragies and effect of public buildings’ central air-donditioning for peak load shifting are proposed based on the demonstration project.Then

the structrure and optimal dispatch model of central air-conditioning for day-ahead peak load shifting are constructed with electric power compay’s minimum compensation fees

considering the constraint of adjustable stragies

dispatch total and signal capacity

and so on.Lastly

as Jiangsu Province demonstration project on non-productive air-conditioning for example

the dispatch schedule in different period is got with CPLEX optimal soft ware.
