Linear Active Disturbance Rejection Control Strategy Based on Improved Quasi-Proportional Resonance for the Inner Current Loop of a Grid-Connected Inverter

Nonlinear and asymmetrical loads in microgrids cause severe current distortion and phase unbalance, presenting critical challenges for grid-connected energy storage inverters. Conventional dq-frame Linear Active Disturbance Rejection Control (LADRC) suffers from two key limitatio...
