Direct control strategy of central air-conditioning load and its schedulable potential evaluation

How to exploit and evaluate the schedulable potential of power system load is a hot concern at home and abroad at present,so the air-conditioning load with larger proportion in the city load is studied. The cycling intermittent operation characteristics of the air-conditioning system are analyzed based on the customer's indoor temperature model. The optimal models are established considering various core influencing factors,i.e. quasi-periodic temperature change,comfort demand of customer,demand response to grid dispatch and so on,and the direct load control strategy of different periods is proposed. Then,an evaluation method of load schedulable potential applicable to the proposed model is summarized from three aspects of peak load shifting,load management and power saving potential. Finally,the optimal air-conditioning load control is conducted and the schedulable potential evaluation method is employed through a simulation example, and the validity and practicability of the proposed strategy and method are verified.
