Huge reactive power surplus a light load operation may force system generators to operate in the under excited mode which reduces system stability margin. In this paper analytical expressions for generator reactive power sensitivities with respect to reactive compensation are derived. A criterion based upon these sensitivities for choosing reactive compensation locations to improve systems steady state stability is proposed. The effectiveness of this proposed criterion is demonstrated through application to the Saudi Consolidated Electric Company (SCECO)-Central Power system.
