Electric utilities are facing an ever increasing pressure to operate the power systems under increasingly harsh circumstances. They are represented by a combination of fast load growth, slowly increasing infrastructure, aging equipment, and more frequent exposure of the control system operators to very improbable and sometimes devastating contingencies. These and other factors have contributed to the growing availability and acceptance of the new generation of monitoring and control technologies to assist the system operators in coping with these new challenges.
A brief overview is presented of the analytical techniques presently used for assessment of accurate (or approximate) tendency of the power systems to undergo voltage collapse. Some of the conventional, as well as advanced and more forward-looking approaches to mitigating such situations are discussed.  The presence of new and modern technologies for power system monitoring, communication, and control imposes on the utilities a logical dilemma. Could new technologies be deployed successfully against voltage collapse?  The answer to that question is economic as much as technical.  The absence of widespread voltage collapse mitigation schemes in the utilities worldwide is the result off misperceived risk that a wide-are blackouts are relatively improbable, and that a very high cost of monitoring and protection systems would rely on the next generation of SCADA-like devices, capable of capturing the system state in real time.
