针对自然聚合方式下集群电采暖负荷基线功率强随机波动性导致其调节能力难以准确可靠挖掘的问题,提出一种考虑平均制热需求的集群电采暖负荷调节能力挖掘策略。调峰前,基于电采暖房间平均制热需求与室内外温差的关联规律平滑整定负荷基线,削弱工况扰动对调节能力可靠性的影响;调峰能力上报时,基于探索的电采暖负荷的可调节功率与可持续时长的关联关系,根据电网需求时长灵活设定集群电采暖负荷可持续提供的调节功率幅值;调峰指令执行时,将室温在人体舒适区间内的柔性转化为集群电采暖实时运行数量的柔性,以纠正实时工况与预设工况间的偏差对调峰响应的影响。此外,通过设计算例验证所提策略的有效性。
Aiming at the problem that the regulation capability of the cluster electric heating load is difficult to be accurately and reliably extracted due to the strong random fluctuation of the baseline power in the natural aggregation mode
a reliable regulation capability extraction strategy for cluster electric heating load considering average heating demand is proposed. Before the peak load regulation
the load baseline is smoothed based on the correlation law between the average heating demand of electric heating room and the temperature difference between indoor and outdoor
so as to reduce the influence of working condition disturbance on the reliability of regulation capability. When the peak load regulation capability is reported
based on the explored relationship between the regulation power of the electric heating load and the sustainable duration
the regulation power amplitude that the cluster electric heating load can sustainably provide is flexibly set according to the grid demand duration. When the peak regulation instruction is executed
the flexibility of the room temperature within the comfort range of the human body is converted into the flexibility of the real-time operation quantity of the cluster electric heating
so as to correct the influence of the deviation between the real-time working condition and the preset working condition on the peak regulation response. In addition
the effectiveness of the proposed strategy is verified by case studies.
