A Synchrophasor Based Optimal Voltage Control Scheme with Successive Voltage Stability Margin Improvement

open access: yesApplied Sciences, 2016
This paper proposes an optimal control scheme based on a synchronized phasor (synchrophasor) for power system secondary voltage control. The framework covers voltage stability monitoring and control.

Protection of Microgrid Feeders Using Impedance Angle Analysis Assisted by Synchrophasor Units [PDF]

open access: yesJournal of Renewable Energy and Environment
The healthy operation of a microgrid is a more challenging task due to the inclusion of various distribution generation (DG) sources. The incorporation of a grid with various distributed sources alters the radial structure of the network, making it ...

Assessment of time synchronization requirements for Phasor Measurement Units

open access: yes2015 IEEE Eindhoven PowerTech, 2015
This paper assesses time synchronization sources suitable for Phasor Measurement Unit (PMU) applications in power systems. The paper investigates PMU phase error due to PMU timing inaccuracy and the presence of current and voltage transformers. This paper also shows that in practical on-field applications of commercial PMUs, the required accuracy of ...

Phasor measurement units, WAMS, and their applications in protection and control of power systems

open access: yesJournal of Modern Power Systems and Clean Energy, 2018
The paper provides a short history of the phasor measurement unit (PMU) concept. The origin of PMU is traced to the work on developing computer based distance relay using symmetrical component theory.

Robust Decentralized State Estimation and Tracking for Power Systems via Network Gossiping

open access: yes, 2013
This paper proposes a fully decentralized adaptive re-weighted state estimation (DARSE) scheme for power systems via network gossiping. The enabling technique is the proposed Gossip-based Gauss-Newton (GGN) algorithm, which allows to harness the ...
