Under the background of dual carbon strategy and coal shortage,the existing demand response mechanism of evaluation and incentive is relatively extensive,causing challenges such as excessive redundancy of invitation and difficulty in mining high-quality users,so the accurate evaluation and dynamic incentive decision method of aggregators' demand response considering contribution degree is proposed. Firstly,the accurate evaluation system of demand response considering static and dynamic process is developed and the static evaluation follows the existing demand response evaluation system at the grid side,while the dynamic evaluation focuses on the consistency between the actual load and the target load in each period. Then,the user contribution index is described from the economic and load dimensions,and a two-part incentive settlement scheme with static and dynamic evaluation is designed. Based on that,the dynamic incentive decision model of aggregator's demand response with the contribution degree is got. Finally,the extensive numerical study confirms that the proposed method can achieve the directional incentive of high-quality users,thus improving the response quality and reducing the invitation redundancy without affecting the existing demand response system.
