A Novel Algorithm for Optimal Harmonic Load Flow including Harmonic Compensation

Engineering, Technology & Applied Science Research, 2023
Load flow analysis is widely used for finding voltage at various parts of a large, interconnected power system. The exponential increase in the use of power electronic devices and the noticeable percentage of integration of renewable energy sources in modern power systems result in the occurrence of non-sinusoidal voltages at various parts of the power

A harmonic compensation approach for interlinking voltage source converters in hybrid AC-DC microgrids with low switching frequency

CSEE Journal of Power and Energy Systems, 2018
In recent years, the hybrid AC-DC microgrid has been well accepted as it combines the advantages of both AC and DC systems. As the microgrid contains both DC sub-grids and AC sub-grids, interlinking DC-AC converters are essential.

Analysis and mitigation of dead time harmonics in the single-phase full-bridge PWM converters with repetitive controllers [PDF]

, 2018
In order to prevent the power switching devices (e.g., the Insulated-Gate-Bipolar-Transistor, IGBT) from shoot through in voltage source converters during a switching period, the dead time is added either in the hardware driver circuits of the IGBTs or ...
