考虑响应误差的工业可调负荷聚合响应策略

Strategy for Aggregated Industrial Flexible Loads Participating in Demand Response Considering Response Errors

针对工业可调负荷聚合参与需求响应具有响应误差的问题,本文提出日前-日内两阶段工业可调负荷聚合响应策略。首先,运用三角模糊数描述响应的不确定性,建立考虑启停响应速度和响应时长的工业可调负荷聚合响应模型;然后,基于激励型需求响应市场,以调用成本最小为目标,提出日前-日内两阶段工业可调负荷聚合响应策略;最后,通过算例结果验证了本文策略的有效性。本文提出的策略有效减少了响应误差带来的影响,提高了工业可调负荷聚合响应的可靠性。。

To address the problem that aggregated industrial flexible loads participating in demand response have re⁃sponse errors,a strategy for aggregated day-ahead and intra-day two-stage industrial flexible loads participating in de⁃mand response is proposed.First,triangular fuzzy numbers are used to describe the response uncertainty,and a model of aggregated industrial flexible loads participating demand response is developed considering the start-stop response speed and response time.Then,based on the incentive-based demand response market,the strategy for aggregated dayahead and intra-day two-stage industrial flexible loads participating in demand response is proposed with an objective of minimizing the dispatching costs.The proposed strategy effectively reduces the impact due to response errors and im⁃proves the reliability of aggregated industrial flexible loads participating in demand response.Finally,simulation re⁃sults verify the effectiveness of this proposed strategy.
