ABSTRACT
This paper addresses the choice of both location and magnitude of inductive reactors. These reactors are needed to enhance system steady-state stability by providing a means to absorb the reactive power surplus at light-load operation. The choice is based upon the sensitivity of the reactive power absorbed by system generators with respect to the reactor location. The spring load condition of SCECO-C power system in Saudi Arabia is used to demonstrate the effectiveness of the method.
