Analysis and Test Verification of Turbine Generator's Leading Phase Operation Capability

open access: yes发电技术, 2019
The generator leading phase operation is an operation mode in which the generator adjusts the excitation to make the generator under-excited and maintains reactive power from the system while maintaining the normal active output.

Transient Stability Enhancement Strategy for Islanded Microgrids Based on Energy Storage–Virtual Synchronous Machine Control

open access: yesEnergies, 2023
In a high percentage of new energy-islanded microgrids, the overall inertia of the system gradually decreases, and the transient stability requirements of the microgrid frequency and voltage become more and more demanding under low-inertia conditions. To

Data-Driven Diagnostics of Mechanism and Source of Sustained Oscillations [PDF]

open access: yes, 2015
Sustained oscillations observed in power systems can damage equipment, degrade the power quality and increase the risks of cascading blackouts. There are several mechanisms that can give rise to oscillations, each requiring different countermeasure to ...

Mitigation of voltage dip and power system oscillations damping using dual STATCOM for grid connected DFIG

open access: yesAin Shams Engineering Journal, 2017
During grid fault, transmission lines reach its thermal limit and lose its capability to transfer. If this fault current enters generator terminals, it will lead to dip in stator voltage and consequently produces torque and real power oscillations.

Voltage Profile Analysis in Smart Grids Using Online Estimation Algorithm

open access: yesJournal of Electrical and Computer Engineering, 2022
Voltage rise is the main obstacle to prevent the increase of distributed generators (DGs) in low-voltage (LV) distribution grids. In order to maintain the power quality and voltage levels within the tolerance limit, new measurement techniques and ...
