基于有限集合的功率预测优化控制研究

Investigation on Finite-set-based Predictive Power Optimization Control

针对三相电压型并网逆变器(GC-VSI),提出了一种基于有限集合的功率预测优化控制策略,为消除系统控制延时对控制性能的影响,提出了两步预测的方法进行补偿。实验结果表明,此方法能减小逆变器功率波动,降低并网电流的总谐波畸变率(THD),具有快速的动态性能,同时对电感参数的变化具有较强鲁棒性。

This paper proposes the finite-set-based predictive power optimization control of three-phase voltage-sourced grid-connected inverters（GC-VSI） and a two-step predictive method to compensate for the impact of system control de- lay.The experiment show the method can reduce the fluctuation of the power and decrease the grid currents＇ total harm- onic distortion （THD）, while keeping fast dynamic performance and strong robustness to inductance parameter＇ s change.
