Demand Response Strategy of Air Conditioning Load Aggregator Based on Non-Cooperative Game

The air conditioning load is a kind of Demand Response (DR) resources. The adverse impact of the load peak on the power grid can be alleviated by dispatching the DR resources. Firstly, the scheduling operation structure of air-conditioning load aggregator (LA) is proposed. Secondly, a multi-level load reduction model of the air conditioning is established based on the characteristics of the air conditioning load. Then the game model of multi-air conditioning LAs is established. A changeable parameter is introduced in the real-time electricity price strategy which is the base of the air conditioning LA game, and the supply curve of the DR market is obtained by continuously changing the value of the parameter. The point where the supply curve intersects with the grid company's demand curve serves as the scheduling basis for the DR. Finally, the strategy is further analyzed by case study.
