Abstract
The proximity of B and L indices to 1 indicates the level of voltage instability of power system and load points, which varies with changing system conditions. To quantify the effect of control measures, the sensitivities of B and L indices to the control measures are newly proposed, based on which the adverse control effects with different sites of load shedding, the non-optimality of local load shedding, the opposite effects of tap adjustment, and the inconsistency of L and B indices with the same control measures, are quantified. The numerical results validate the accuracy of the sensitivity model by comparing with the continual calculation.
