考虑贡献度的聚合商需求响应精准评估与动态激励决策

在双碳战略和缺煤背景下，针对现有需求响应评估激励机制相对粗放，存在邀约冗余度过大、优质用户难以挖掘等问题，文中提出考虑贡献度的聚合商需求响应精准评估与动态激励决策方法。该方法首先建立考虑静、动态过程的需求响应精准评估体系，其中静态评估延续现有需求响应评估方案，动态评估关注每时段实际负荷与目标负荷的吻合度；进一步地，从经济和负荷维度提出用户贡献度指标，设计结合静、动态评估的需求响应两部制激励结算方案，并据此建立考虑贡献度的聚合商需求响应动态激励决策模型。通过算例验证所提模型可在不影响现有需求响应体系前提下，实现优质用户的定向激励，提升需求响应品质和降低邀约冗余度。

Accurate evaluation and dynamic incentive decision of aggregators' demand response considering contribution degree

Under the background of dual carbon strategy and coal shortage, the existing demand response mechanism of evaluation and in-centive 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, that 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, improve the response quality and reduce the invitation redundancy without affecting the existing demand response system.
