As a common interface circuit for renewable energy integrated into the power grid, the inverter is prone to work under a three-phase unbalanced weak grid. In this paper, the instability of grid-connected inverters under the unbalanced grid condition is investigated. First, a dual second-order. .
Low power grid-connected inverters using L-type filters have the advantages of simple structures. However, due to the weak suppression of higher harmonics and the fact that the voltage of point of common coupling (PCC) is no longer clamped by the grid voltage under the ultra-weak grid, if the PCC. .
The LCL-type grid-connected inverter is a typical nonlinear system that weakens the controllability of the grid-connected energy. To address these challenges, this study employs feedback linearization theory to transform the inverter into a standard linear system. Subsequently, it utilizes linear.
