Technical FAQs 4
Are grid-following inverters stable under weak grids?
The grid-forming type is equivalent to a voltage source and a resistor in series, and the grid-following type inverter is equivalent to a controlled current source and a resistor in parallel, and is, therefore, also known as a current-controlled inverter. This paper focuses on analyzing the stability of grid-following inverters under weak grids.
Why is a grid connected inverter unstable?
The operation of the grid-connected inverter (GCI) in weak grid conditions presents a risk of instability due to the presence of high grid impedance and the negative impedance effect of the phase-locked loop (PLL).
Can grid voltage reshape a grid-connected inverter?
In the study of Yang, a feedforward function of grid voltage is constructed that can totally remove the impact of PLL on the system's output impedance, after which a grid-connected inverter's impedance reshaping control approach based on grid voltage feedforward is suggested.
Can an inverter grid-connected system operate under weak grid conditions?
Based on the aforementioned analysis, it can be concluded that when only the ID-PLL structure is employed, the inverter grid-connected system can operate steadily under extremely weak grid conditions (SCR = 1.37); however, the transition time from full load to half load is long, indicating insufficient dynamic performance.
