This study focuses on microgrid systems incorporating hybrid renewable energy sources (HRESs) with battery storage (BES), both essential for ensuring reliable and consistent operation in off-grid standalone systems. The proposed system includes solar energy, a wind source synchronous turbine, BES. Hybrid particle swarm optimizer (PSO) genetic algorithm (GA) combined active disturbance rejection control (ADRC) (PSO-GA-ADRC) are developed to regulate the frequency amplitude of AC bus voltage via load-side converter (LSC) under various operating conditions. approach further enables efficient management accessible generation general consumption through bidirectional battery-side (BSC). Additionally, method also enhances power quality across link mentoring photovoltaic (PV) inverter function as shunt filter (SAPF), providing desired harmonic-current element nonlinear local loads well. Equipped an extended state observer (ESO), PSO-GA-ADRC provides estimation compensation disturbances such modeling errors parameter fluctuations, stable solution interior current loops. positive results from hardware-in-the-loop (HIL) experimental confirm effectiveness robustness this strategy maintaining real-world scenarios.
