“…The voltage stability index introduced by Barenjee and Das is based on the two‐bus equivalent circuit of a distribution network and active and reactive power losses. The equations are written as follows:

P_{loss} = \frac{((), P^{2} + Q^{2})}{V_{2}^{2}} R .

Q_{loss} = \frac{((), P^{2} + Q^{2})}{V_{2}^{2}} X .

VSI = V_{1}^{2} - 2 PR - 2 QX - normalR P_{loss} - normalX Q_{loss} .

“…This index includes many variables, so its calculations are complex and time‐consuming. The index presented in previous studies is also able to examine the voltage stability of the distribution network, and its steady‐state value is near unity. However, the numerical value of the index in the base load state is much less than unity, and this type of operation may provide the operator incorrect information on network conditions.…”

“…However, the numerical value of the index in the base load state is much less than unity, and this type of operation may provide the operator incorrect information on network conditions. In Banerjee et al, the introduced index is based on active and reactive power losses, and this dependency may add to the complexity of the calculations. Furthermore, in Chakravorty, the stability index is based on the two‐bus equivalent circuit of the distribution network, the sending and receiving end bus voltages, as well as the active and reactive power.…”

Summary This study evaluates the voltage stability of distribution networks by introducing a new index. Using the introduced index, it is feasible to analyze the network buses from voltage stability point of view. The index can increase the accuracy along with simplifying and reducing the computational burden. The suggested index is then developed to take into account the effect of distributed generations and tap changers. It has also been enhanced to be employed in smart grids. By doing so, the index value will depend merely on the bus voltages. Consequently, the calculation burden of the index is decreased significantly. In order to analyze the proposed indices, they are calculated in different load models. Two standard 33‐ and 69‐bus distribution networks are utilized to evaluate the performance of the introduced indices. The obtained results are compared with those of other indices showing that the suggested indices lead to less computational burden and sensible and acceptable results.
