摘　　要：针对可再生能源发电的不确定性和间歇性问题,提出集成功率管理和非线性控制的策略,设计了一种混合光伏/风电/储能电池的微电网系统。该策略采用最大功率点跟踪算法,以最大限度地从每种可再生能源中提取能量。同时,设计了一种滑模控制技术,以提高系统的稳健性并确保有效的能源管理,不受系统扰动、负载波动、辐射和风速变化的影响。该优化框架在交流微电网系统上进行了测试和验证,证明了其有效性。仿真结果表明,该系统能够有效地管理功率流,并保持恒定的直流母线电压和负载电压水平,确保了系统的平稳运行。A hybrid PV/wind/storage battery microgrid system is developed using a strategy that integrates power management with nonlinear control to address the uncertainties and intermittencies of renewable energy generation.This approach employs a maximum power point tracking algorithm to optimize energy extraction from each renewable source.Additionally,a sliding mode control technique is introduced to enhance system robustness,ensuring efficient energy management regardless of system disturbances,load fluctuations,and variations in radiation and wind speed.The optimization framework was tested and validated on an AC microgrid system,demonstrating its effectiveness.Simulation results indicate that the system successfully manages power flow and maintains stable DC bus and load voltage levels,ensuring smooth operation.
