What is the stability criterion for inverter-grid system?

Interaction between the grid and the inverter may generate harmonic resonances that lead to reduced power quality and even instability. To analyse the stability of the inverter-grid system using impedance-based stability criterion, inverter impedance has to be known.

How does a grid-connected multi-inverter system change stability?

As the active power of inverter 2 increases, the system transitions from stability to instability. Decreasing the active power of inverter 1 restores stability to the system. These variations in system stability are consistent with Fig. 15, confirming the applicability of the proposed algorithm to the grid-connected multi-inverter system. Fig. 14.

Do grid-connected inverters have stability margins?

To achieve quantitative analysis of stability margins and provide decision guidance for control optimization, this paper constructs the quantified SSSR for grid-connected inverters using the impedance method. Additionally, the stability mechanism of grid-connected inverter systems is analyzed under full operating conditions.

How stable is a grid-connected inverter system?
