FAQS 4

Why do grid-connected inverters have a large damping ratio?

In order to promise the steady-state and dynamic performance, large damping ratio is expected due to weak damping ability of grid-connected inverter with LCL filter. However, it is still unclear to calculate the damping ratio accurately and analyze maximal damping performance in fully discrete-time domain.

How to achieve maximum damping ability of inverter?

Proposing an improved damping characteristic analysis strategy to obtain maximal damping ability of inverter. Derivation of the plant model in fully discrete-time domain. Considering three influence factors simultaneously and adapting to single-phase and three-phase systems well.

Why is damping performance comparison important in grid-connected inverter?

Moreover, damping performance comparison is also an interesting research idea under different feedback algorithms. On the other hand, virtual synchronous machines technique has been employed in grid-connected inverter and its damping performance is also imperative to be improved. These issues are also worthy to be addressed in the future.

Why does grid-connected inverter with LCL filter have a high damping ratio?

Grid-connected inverter with LCL filter, which is regarded as a common interface, plays a significant role in distributed generation system. In order to promise the steady-state and dynamic performance, large damping ratio is expected due to weak damping ability of grid-connected inverter with LCL filter.
