计及反弹效应的温控负荷有序削峰策略

Orderly Peak Load Shaving Strategy of Thermostatic Controlled Loads Considering Payback Effect

近年来,高峰用电负荷逐年增长,峰谷差进一步拉大,给电网运行带来了很大的压力。因此,以电热水器和空调两种温控负荷作为受控对象,考虑负荷调控过程中出现的反弹效应,基于全时段和分时段两类控制策略,提出了一种负荷调度的线性规划数学模型,从而最大程度上实现负荷峰值的有序削减。通过对南京市夏季典型日负荷的调控,分析了不同条件下的峰值削减情况,验证了此模型的有效性。

In recent years,peak load has been growing yearly and peak-valley difference of load has been increasing,which brings great pressure on grid operation. Two typical thermostatic controlled loads（ TCLs） ie,water heater and air conditioning are selected as controlled objects. The phenomenon of payback effect is taken into consideration and a linear planning mathematical model of load regulation is put forward to maximize the amount of peak load reduction orderly through full-time and split-time control strategies.Through the load regulation of typical summer day in Nanjing,the amount of peak load reduction under different conditions are analyzed. The results verify the validity of the proposed linear planning mathematical model.
