Through the dispatching of demand side response resources，the adverse effects of distributed power output fluctuation on grid operation can be alleviated，and the consumption of renewable energy can be promoted． Firstly，based on the operation framework of the load aggregator，the cost and benefit of the load aggregator were analyzed． In the component of the load aggregator cost，the demand response compensation strategy based on users' comfort was proposed． Secondly，the temperature variation model of air conditioning load was established． Finally， the air conditioning load optimization dispatching model was proposed． The objective function of the model is the maximum total revenue of the air conditioning load aggregator，taking into account the air conditioning temperature，wind power fluctuation and aggregator revenue constraints． The simulation results show that the proposed model has good economic benefits and improves the smoothing effect on distributed wind power fluctuations．
