This short paper compares different phasor measurement unit (PMU) systems according to their power placement. The different algorithms used for the optimum PMU placement are discussed. They are related to their usefulness in power management.
Power System Voltage Stability Assessment Using Network Equivalents-A Review, Nagendra, P., Datta T., Haider S., and Paul S. , 2010, Volume 10, Issue 18, p.2147 - 2153, (2010)
Reviews articles as of 2010 on voltage stability across power networks. The review shows that most of the multi-bus power networks are developed under Thevenin's theory. Some innovative approaches quickly provide information needed to assess voltage stability. System voltage stability, which is important for system operators, is assessed online. The idea of voltage collapse correction is explored by some of the reviewed articles.

According to the article, utility companies where already using synchrophasors technology to visualize in real-time information about power distribution and quality. Some of the questions that phasor synchronization answered are: • Proper phasing within a substation breaker panel lineup without using additional test equipment. • Provided substation system topologies and data measurement refinements. • Improved visualization over a wide area by aligning data with varying data rates. • Analysis of disturbances in a power system, including small ones. • Monitor and quickly analyze disturbances. • No longer is estimation necessary since measurement is real time.
