Unlike some convex-optimization techniques for the reactive power planning solution, in the proposed approach the taps settings of under-load tap-changing of transformers are modeled as a mixed-integer linear set equations. Are also considered the continuous and discrete variables for the existing and new capacitive and reactive power sources. The problem is solved for three significant demand scenarios (low demand, average demand and peak demand). Numerical results are presented for the CIGRE-32 electric power system.engConvexdemand scenariosmixed-integerreactive power planningreactive power sourcestaps settingsTrabalho apresentado em evento10.1109/PESGM.2014.6939057Acesso aberto2-s2.0-84930989230
