Optimum load shedding for avoiding steady-state voltage instability

摘要

The paper addresses the problem of load shedding as an emergency means for avoiding occurrence of voltage instability in distribution and transmission power systems. Optimum locations of loads to be shed are found together with their optimum required quantities. L-indicator index is used for this purpose with a modified new technique. Applications to a test system is presented to validate the applicability of the proposed new technique to any system of any size.
