    摘要:

    针对需求侧负荷资源调控中存在的异构特性影响问题,提出一种基于泛化指标的异构温控负荷群联合调控策略。该策略首先通过考虑偏差修正及行为分析,在温控负荷等效热电模型基础上进一步提升其精细化程度及适用性;然后综合考虑可调控能量空间及可转移时间,建立泛化评价指标,实现对异构温控负荷态势的标准化评估分析,进而指导异构负荷群组合优化调控;最后通过实验仿真验证所述方法能够良好适用于异构温控负荷调控需求, 并保证异构负荷协同下的调控精度,同时亦提升温度分布合理性。

    Abstract:

    Considering the influence of heterogeneous characteristics on the demand side load resource regulation, a joint control strategy based on generalization index is proposed for heterogeneous thermostatically controlled loads (TCLs). The error correction and the behavior analysis is taken into account firstly, and the degree of refinement and applicability of the equivalent thermoelectric model for TCLs is further improved. Consequently, a generalization index is proposed with the consideration of the controllable energy space and the transferable time, which realizes the standard evaluation of the operating state of heterogeneous TCLs, and can be further utilized to guide the combinatorial optimization of heterogeneous load groups. Finally, the experimental simulation indicates that the proposed method can perfectly match the demand for the control of heterogeneous TCLs, and can maintain the control accuracy and improve the temperature distribution at the same time.
