Demand Response Analysis of Load Aggregator Considering Energy Storage and User Response Uncertainty

Demand response can involve demand side resources instead of supply side resources into electricity market services. Firstly, this paper establishes a demand response structure based on load aggregator, which can aggregate the response resources of small and medium-sized users to participate in the demand response. Secondly, the response uncertainty of the main flexible load on the user side is analyzed, and the model of user's response difference is established. Then, this paper proposes an LA's response strategy that combines energy storage equipment to eliminate the risk of LA's insufficient response caused by user's response uncertainty, and the contact quantity of energy storage equipment and the optimal economic incentives can be determined through the LA's response profit maximization function. Finally, the effectiveness of the proposed model is verified by a simulation.
