6 FAQs about [Microgrid Active Power Filter]

What is the role of active filters in a power grid?

In this scenario, which comprehends the real modern power grids, active filters play a key role as an interface for connecting the REN to the power grid.

Can active filters improve power quality?

Edited by Ahmed F. Zobaa From harmonic compensation to interface with renewable energy sources, active filters are capable to improve power quality, increase the reliability of the power grid, and contribute to make feasible the implementation of decentralized microgrids.

What is an active filter?

An active filter is comprehended by power and control stages. The power stage comprises a voltage source converter (VSI), with a storage energy element (capacitor) at its DC link, inductor filter (L fp), and small passive filters (Z fp) to provide a low impedance path to the high-frequency components of the produced current by the VSI (i Lfp).

Can a sinusoidal grid current be extracted from an active filter?

It is important to highlight that when sinusoidal grid currents are required, considering unbalanced or distorted grid voltages, a circuit capable to extract the fundamental positive-sequence component of the grid voltages must be added to the control algorithm of the active filter, independently of the chosen methodology. Figure 4.

How do active filters work?

Basically, once these active filters share the same grid voltage, they are conditioned to produce controlled currents such that their output impedance is modified according to the capabilities of sharing the active- and reactive powers of the load.

How to integrate active filters with DFIG wind turbine?

Another possibility is integrating active filters with Doubly-Fed Induction Generator (DFIG) wind turbine as illustrated in Figure 18, with one converter connected to the DFIG (RSC—rotor side converter) and the other one presents shunt connection to the power grid (GSC—grid side converter).
