A global Approach for Var/Voltage Management

Abstract A new methodology is presented which aims to provide a global approach for var/voltage management and scheduling. A formal automatic procedure is proposed in order to analyse the present system data from a var/voltage viewpoint and to provide corrective strategy whilst optimising the system. The concept of potential resources is introduced to allow identification of weak points and to determine corrective strategy in terms of relaxation of limits or var source expansion. A prototype software package for microcomputers is described and numerical results are reported.
