“…Fig. 14 shows constant ϕ curves for buses 17 and 30 obtained using a continuation power flow algorithm [17]. Between these buses, there is one of the tap‐changing transformers of the system, whose taps are kept at non‐nominal values in the simulation.…”

The model for tap-changing transformers currently in widespread use consists of an impedance, measured in a shortcircuit test with a nominal tap, in series with an ideal transformer. The use of this model in voltage stability studies leads to qualitatively incorrect results. For demonstration purpose, a small circuit and the concepts of maximum load, equivalent load impedance and voltage control effects are used. An improved model that takes into account laboratory results, circuit laws and voltage stability theory is proposed. Using IEEE test systems, different results are shown for the conventional and proposed models.

“…It should be mentioned that in buyback DRPs, load increment might be happening during off peak hours. The VSM in the load domain (apparent power) indicates the power system maximum loadability in terms of voltage stability [29], which is defined as follows
