Awareness and Control Strategy for TCLs Considering Discrete Control Deviation

针对温控负荷离散化控制模式导致的临界温度效应累计偏差,提出一种计及离散控制偏差的温控负荷集群调控策略。通过引入修正因子改进负荷可消纳能力评估模型,并以热水器群为主要研究对象,将用户用水行为引入统一负荷模型,提升模型与实际环境的拟合性;提出负荷态势计算指标,基于其实时状态,以温度裕度、时间裕度和容量裕度为子指标进行综合,实现对于负荷调控能力的评价。仿真结果证明：综合考虑用户用能需求情况下,引入修正因子和用户行为分析的感知调控策略,可实现精准负荷调控,降低负荷资源储备需求。

Discretization control mode for thermostatically controlled load （TCLs） leads to the critical temperature effect （CTE）, which causes cumulative deviation. An awareness and control strategy for TCLs considering discrete control deviation was proposed to improving the load capacity evaluation model by introducing a correction factor. In addition, focus on the water heater group here as research object, the user＇s water using behavior was introduced to construct the uniform load model, and the fitting performance of the model and the actual environment was improved. Further, a load situation calculation index was proposed. Based on the real-time state, temperature margins, time margins, and capacity margins were integrated as the sub-indicators to evaluate load control capabilities. The simulation results show that the control strategy can realize accurate load control and reduce the demand of load resource reserve.
