Stalling of residential air conditioners (RACs) following a transient fault can delay the voltage recovery ranging from 3 to 20 seconds. This phenomenon is referred to as fault-induced delayed voltage recovery (FIDVR). Several aggregated RAC models have been presented to replicate the actual FIDVR events. However, they usually have two main drawbacks as: i) considering independent stalling voltage and stalling time for all RACs, ii) resulting in only two ultimate modes; either 100% stalled or 100% normal running. This paper amends the abovementioned shortcomings by proposing a simple and effective performance-based RAC model. The proposed model utilizes a simple explicit relation between the stalling voltage and its required time to stall the RAC, furthermore, it can stall a fraction of RACs based on the voltage dip characteristics. The experimental results support the proposed model and computer simulations employing the IEEE 118-bus test system and Iran's electricity grid reveal the effectiveness of the proposed model.

用于 FIDVR 研究的改进的住宅空调聚合模型

发生瞬态故障后住宅空调 (RAC) 的失速可能会延迟 3 到 20 秒的电压恢复。这种现象被称为故障引起的延迟电压恢复 (FIDVR)。已经提出了几个聚合的 RAC 模型来复制实际的 FIDVR 事件。然而，它们通常有两个主要缺点：i) 考虑所有 RAC 的独立停转电压和停转时间，ii) 仅导致两种最终模式；100% 停滞或 100% 正常运行。本文通过提出一种简单有效的基于性能的RAC模型来修正上述缺点。所提出的模型利用堵转电压与其使 RAC 堵转所需的时间之间的简单显式关系，此外，它可以根据电压骤降特性堵住一小部分 RAC。
