控制异质负载群体功耗的安全协议
Safe Protocol for Controlling Power Consumption by a Heterogeneous Population of Loads
摘要：
最近的研究集中在转移人口中的每个TCL的温度设定点控制的总功率的合奏的恒温控制负载（TCL）。然而，已知设定点的突然偏移与不期望的功率振荡相关联，这需要闭环控制策略来调节群体的总功率消耗。在这篇文章中，我们提出了一种新的方法，我们称之为“安全协议”，以实现温度设定点的转变。它示出的分析和验证数值，通过移动的设定点“安全地”的总功耗可以改变到一个不同的值在一个TCL的周期持续时间的顺序的时间范围内，避免不希望的振荡，否则看到在一个“突然”的转变。我们讨论了如何在设定点的安全转移下转移的多余的聚合能量可能会在短时间内减轻由于异常能量产生的负担。
英文摘要：
Recent studies on control of aggregate power of an ensemble of thermostatically-controlled-loads (TCLs) have been concentrated on shifting the temperature set points of each TCL in the population. A sudden shift in the set point, however, is known to be associated with undesirable power oscillations which require closed-loop control strategies to regulate the aggregate power consumption of the population. In this article, we propose a new approach which we term as a "safe protocol" to implement the shift in temperature set point. It is shown analytically and verified numerically that by shifting the set point "safely" the aggregate power consumption can be changed to a different value within a time frame of the order of a TCL's cycle duration and avoid the undesired oscillations seen otherwise in a "sudden" shift. We discuss how the excess aggregate energy transferred under a safe shift in the set point could potentially mitigate the burden due to abnormal energy generation within a short time span.
