摘要

首先描述了典型温控负荷的热力学模型，并在此基础上讨论了常用温度设定控制策略下负荷温度分布变化及负荷开关状态变化。随后以温度队列为基础，提出了一种基于负荷温度的密度聚类集群控制策略。该策略考虑负荷在温度区间内的分布情况，通过密度聚类算法对负荷群进行聚类分析并确定密集区域与非密集区域；随后计算温度节点和补偿节点并确定设备响应群体和温度设定值；最后以温度设定值为响应信号对负荷群进行控制。以常用温控负荷电热泵为控制对象进行仿真分析，与常用温度设定控制下负荷群开关变化次数进行了对比。结果显示，负荷在控制中开关状态变化次数明显降低，负荷群中发生开关状态变化的负荷数目明显减少。

Abstract

Firstly

the thermodynamic model of typical temperature-controlled load is described. Based on this

the variation of load temperature distribution and the change of load switch states with the control strategy of common temperature setting are discussed. Then

based on the temperature queue

a cluster control strategy of density clustering based on load temperature (DCBLT) is proposed. This strategy considers the distribution of the loads in the temperature interval

clustering analysis of load cluster is made by DCBLT method and the dense region and non-dense region are determined. Temperature nodes and compensation nodes are calculated

and device response group and temperature setting value are determined. Finally

the load group is controlled by taking the set temperature as a response signal. The electric heat pump of common temperature-controlled load is used as the control object to make the simulation analysis. Compared with the switch changing times of the load group with the common temperature setting control

the results show that the changing times of switching states is obviously reduced during the control and the number of loads in which the switch state changes is significantly reduced.
