Review of Phasor Estimation Algorithms for Phasor Measurement Units and Their Applications

The role of Phasor Measuring Units (PMUs) is becoming more and more important in modern power networks as dispersed generation and renewable energy sources are integrated. These units provide important insights into the changing energy distribution environment and are crucial instruments for assessing the Power systems' dynamic behavior. This makes the effective functioning of Phasor Measuring Units (PMUs) a crucial prerequisite. Optimal operation is not only necessary to guarantee the steadiness and dependability of the electrical network but is also instrumental in facilitating the seamless assimilation of various energy sources. The efficiency and robustness of contemporary power systems are significantly improved by the accuracy and effectiveness of PMUs in gathering and interpreting Phasor data. To highlight the critical need of accurately and promptly identifying voltage and current Phasors, this paper reviews several Phasor estimate techniques and emphasizes the significance of PMU operation efficiency. The paper also conducts a comprehensive examination of PMU concepts and structures. It delves into a range of research publications that highlight the flexible uses of PMUs in electric system observing and managing, going beyond talks about algorithms and highlighting their crucial position in the evolving energy scene.
