Air conditioning load participating in power grid peak clipping will be very important in power demand side management in the future. The air conditioning system of public buildings has such advantages as a large capacity of load

good adjustable performance

and little influence on social production. This paper analyzes the peak-load regulation ability of public building air conditioning load and proposes the basic idea of peak-load virtual regulation in the power grid with public building air conditioning load. Based on the above

the concrete realization manner of peak-load virtual regulation is presented

which includes four aspects

the building layer

the terminal layer

the communication layer and the host layer. The operation mode of peak-load virtual regulation is also put forword

namely

the operation framework and operation process. This work is supported by State Grid Corporation of China (No. SGJS0000YXJS1400212).
