Grid-connected inverter in microgrid

4 FAQs about [Grid-connected inverter in microgrid]

Does inverter control affect the power quality of microgrid 3?

The inverter is a key link in the power electronic converter, which affects the power quality of entire microgrid 3. However, conventional inverter control methods can easily lead to poor control performance in complex engineering conditions, which can have adverse effects on the power quality of microgrids.

What is an inverter based microgrid?

An inverter-based MG consists of micro-sources, distribution lines and loads that are connected to main-grid via static switch. The inverter models include variable frequencies as well as voltage amplitudes. In an inverter-based microgrid, grid-connected inverters are responsible for maintaining a stable operating point [112, 113].

What is grid-forming-based inverter control?

The grid-forming-based inverter control consists of a virtual synchronous machine (VSM) for regulating the voltage and frequency of the power system along with active power control and reactive power control for significantly improving the dynamic performance of the grid-connected PV system.

What is grid-following based inverter control?

The grid-following-based inverter control consists of a phase-locked loop and inner current control loop for providing the control for the inverter currents as shown in Figure 3. This work utilizes active–reactive power control (PQ control) in the outer control loop.
