Barrier-Function-Constrained Residual RL-Based Current Control for LCL-Filtered NPC Inverters under Weak-Grid Operation
As renewable energy penetration continues to grow, grid-connected inverters are increasingly required to operate reliably under weak-grid conditions, where low short-circuit ratios, changing grid impedances, and rapid disturbances reveal the limitations of conventional fixed-gain PI current controllers. Reinforcement l...
