Abstract
Power system is now operating under more severe operating conditions than ever before. With more efficient use of transmission lines, the power system may frequently operate near the limit of voltage stability. As a result, there is a high probability that the system will suffer voltage instability or that a voltage collapse may occur. Voltage security is an important subset of power system stability, and has received increasing concerns in research after several well-known blackouts. Therefore, voltage stability analysis is a major concern in power system planning and operation. Phasor Measurement Units (PMUs) by employing satellite technology, offer a state of Wide Area Monitoring System (WAMS) for improving power system monitoring, control and protection.
