Grid-tied inverters are widely used for interfacing renewable energy sources or storage
devices to low-voltage electrical power distribution systems. Lately, a number of different …

As the use of distributed generation with power electronics-based interfaces increases, the
separation between DC and AC parts of the grid is reduced. In such inverter-dominated AC …

To guarantee system stability, proportional capacitor-current-feedback (CCF) active
damping control has been widely used in LCL-type grid-connected inverter. However, when …

This article takes a deep insight into the passivity-based design of LCL-filtered inverter with
grid current control and capacitor current active damping. It reveals that although an optimal …

For LCL-type grid-connected inverters, inverter-side current, grid-side current, capacitor
current and voltage are four commonly used variables in the control serving as different …

The frequency-domain passivity theory offers an effective way to assess the stability of
inverters connecting to complex grid conditions, eg, inductive grid, capacitive grid, and …

The frequency-domain passivity theory offers an effective way to assess the stability of
inverters in a complex grid. In this article, a unified impedance model, suitable for either …

Grid-side current control based on capacitor-current-feedback (CCF) active damping is a
common control method for LCL-type grid-tied inverters. The control system should not only …

The interconnection stability of a grid-tied inverter system can be investigated not only based
on classical control theory, eg, Nyquist criterion, but also from the energy dissipation point of …

The frequency-domain passivity theory suggests that incorporating passive output
admittance in grid-connected inverters (GCIs) can effectively mitigate system instability …
