nowadays, power system tends to be operated in heavily stressed load, which can cause voltage stability problem. Moreover, occurrence probability of contingency is increasing due to growth of power system size and complexity. This paper proposes a new preventive control scheme based on voltage stability and security monitoring by means of wide area monitoring systems (WAMS). The proposed control scheme...
New PMU placement algorithm considering network connectivity, zero injection bus, reliability of N−1 line contingency and voltage stability performance (enhancing Voltage Stability Index) are proposed in this work. Reliability and voltage stability level are selected to determine the security level of Wide Area Monitoring System and priority bus. Optimization problem is formulated by minimizing the...
