- Abstract
The high penetration of residential air conditioners (RACs) poses a growing concern in emerging fault‐induced delayed voltage recovery (FIDVR) in power systems. FIDVR is expected to be a significant threat to the stability and reliability of future power grids. Hence, the system planners should carry out appropriate simulation studies to mitigate the severe consequences of FIDVR events. A key question to implement these studies is how to determine the worst condition which results in FIDVR. Most of the actual FIDVR events have been experienced in the hot hours of the day and this issue makes one curious to think about the relationship between the FIDVR events and the ambient temperature. In this regard, a novel temperature‐dependent RAC model is presented and verified by using laboratory tests. Furthermore, two cases with different power system loading patterns, i.e. the peak temperature hour and the peak demand hour, are examined. The proposed RAC model is implemented on the IEEE 118‐bus test system. Moreover, an actual FIDVR event reported in Iran has been reproduced employing the proposed RAC model. Implemented simulations reveal that to precisely reproduce the recorded FIDVR event, it is necessary to consider the ambient temperature when the fault has been occurred.
