It is becoming increasingly important for power system planning and operating engineers to be capable of performing comprehensive voltage stability analyses of the systems. This need is largely due to the recent trends towards operating systems under stressed conditions—as a result of increasing system loads without sufficient transmission and: or generation enhancements. There have been many failures, due to voltage instability in power systems around the world. In recent years many researchers have suggested techniques for voltage stability analysis considering both static and dynamic aspects. This paper is mainly concerned with analysis of steady state voltage stability. The contributions are: A method to compute voltage collapse proximity based on new operational load flow (OLF) and sensitivity of reactive control variables; An algorithm for reactive power optimization using LP technique to improve voltage stability. Simulated case studies conducted on two Indian power networks based on the proposed techniques.
