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. . This book introduces planning method of power control configuration and structuring method of signal process link for grid-connected power conversion. It is revealed that power grids with a higher short circuit ratio (SCR) or lower. . Although the performance of grid-connected inverters can be adaptively adjusted according to the SCR to ensure stable operation under a wide range of SCR variations, this significantly reduces their responsiveness and makes it challenging to meet grid connection requirements.
