As consequence, the networks suffer overloads in a more frequent way. One parameter that has strong influence on transfer capability is the reactive power flow. A sensitivity analysis can be used to find the best solution to minimize the reactive power flows and relief, the overload in one transmission line. The proposed methodology consists on the computation of two sensitivities based on the use of the Lc matrix from CRIC (Constant Reactive Implicitly Coupled) power flow method, that provide a set of actions to reduce the reactive power flow and alleviate overloads in the lines: (a) sensitivity between reactive power flow in lines and reactive power injections in the buses, (b) sensitivity between reactive power flow in lines and transformer's taps. © 2006 IEEE.engPower Transmission LinesReactive Power ControlSensitivityCoupled methodEnergy marketsFree accessIn-linematrixPower flowsPower transactionsReactive power flowReactive power injectionsTransfer capabilityTransmission lineTransmission systemsElectric linesElectric power transmissionSensitivity analysisTransmission line theoryReactive powerSensitivity analysis for overload-relief in transmission lines using an implicitly coupled method (CRIC)Trabalho apresentado em evento10.1109/TDCLA.2006.311392WOS:000246244800166Acesso aberto2-s2.0-82955194455
