What are the global trends in harmonic mitigation methods of AC microgrid?

Furthermore, this overview draws a sketch on the global trends in harmonic mitigation methods of an ac microgrid directly applicable to today's smart grid applications. The microgrid concept has been emerged into the power system to provide reliable, renewable, and cheaper electricity for the rising global demand.

What is decomposed grid harmonic current suppression (DHS)?

To address this issue, a decomposed grid harmonic current suppression (DHS) method with proper feedforward point of common coupling voltage and feedback VSG output current as well as nonlinear load current is proposed for VSG-based microgrids.

Are harmonic mitigation methods a hierarchical control strategy?

Hence, the main goal of this article is to clearly present a comprehensive review of harmonic mitigation methods from a hierarchical control viewpoint. The control strategies proposed to mitigate harmonics are classified into three groups: primary, secondary, and tertiary.

What is the difference between DHS and conventional harmonic control methods?

Compared with conventional harmonic control methods, the DHS method reduces the control sensitivity to system parameters including line impedance, grid impedance, and system shunt capacitance, improving the adaptivity of harmonic control in distorted grids.

What is a microgrid power system?

The microgrid concept has been emerged into the power system to provide reliable, renewable, and cheaper electricity for the rising global demand. When the microgrids are introduced, there will be several concerns, such as active and reactive powers' sharing, load management, connecting to the main grid, and voltage and current deviations.
