无功优化IEEE论文With the increased loading of existing power system, the problem of voltage stability

and voltage collapse has become a major concern in power system planning and operation. The

dependence of the system voltage profile on reactive power distribution forms the basis for reactive

power optimisation. The technique attempts to utilises fully the reactive power sources in the

system to improve the voltage profile and also to meet the reactive power requirements at the

AC–DC terminals to facilitate the smooth operation of DC links. The method involves successive

solution of steady-state power flows and optimisation of reactive power control variables with

unified power flow controllers using linear programming technique. The proposed method has-With the increased loading of existing power system, the problem of voltage stability
