Introduction Synchronized phasor measurement units (PMUs) were first introduced in early 1980s. Also, the performance of the voltage stability assessment algorithm using wide area synchrophasor measurements from the key synchronous generator in each respective cluster was tested online for the prediction of the system's margin to voltage collapse using a testbed comprising of a Programmable Logic Controller (PLC) in a hardware-inthe . Phasor measurement units are considered one of the most important measuring devices in the future of power systems. Definitions and representations Phasor is defined as "a complex equivalent of a sinusoidal wave quantity such that the complex modulus is the cosine wave amplitude and the complex angle is the cosine phase angle" [1]. This bibliography will aid academic researchers and practicing engineers in adopting appropriate topics and will stimulate utilities toward development and implementation of software packages. . Time tag and synchronization . Real time synchrophasor measurements are already being applied for system monitoring and eventually may enhance or even replace the state estimator in system operations. The estimated system state is then obtained by formulating the optimization problem to minimize the measurement errors To expand bulk electric system visibility and enable PJM to better detect High Impact Low Frequency dynamic events and perform its reliability obligations, PJM stakeholders endorsed an initiative to expand the installation of synchrophasor technology across the grid.
