Optimal Co-design Passive Damping LCL Filter and Controller for Grid-Forming Inverter

Abstract

This paper proposes an integrated design method for a passive-damping LCL filter and a Dual-Loop Controller that simultaneously considers various design requirements by utilizing Multi-Objective Artificial Bee Colony (MOABC). The proposed method automatically searches for the optimal parameter combination using the constraints and objective functions of the filter and controller to ensure stable operation of Grid-Forming Inverter (GFMI). The superiority of the proposed method has been demonstrated through MATLAB/Simulink, and it is expected to contribute to enhancing the stability and reliability of GFMI.
