About the paper

This award-winning paper titled "Parameter Optimization of LCL-Type Grid-Connected Inverter Filter in Weak Power Grid Using NSGA-II Algorithm" provides a parameter optimization method for LCL type grid-connected inverter filters in weak power grids based on the NSGA-II algorithm. It models a single-phase inverter system in weak power grids, using the boundaries of traditional parameter design method as constraints and the parameters to be optimized as decision variables. The solution set of the optimal solutions is obtained through iterative optimization of multiple objective functions, and through stability analysis, a representative solution is selected from the solution set as the optimization solution, greatly improving the filtering effect and weak network resistance of the inverter.
