Abstract

The authors present a procedure for dispatching reactive power when voltage deviations are not acceptable. The proposed method, intended for real-time use, determines which control variables are actually effective for solving voltage violations. Efficiency is measured according to sensitivities, current voltage profile and reserve margin of control variables. The selected control variables are rescheduled in proportion to their efficiency coefficients. State-of-the-art sparsity techniques are used to speed up computation of sensitivities. An example is included to show the effectiveness of the method
