摘　　要：逆变器是光伏发电并入电网的重要一环,通过逆变器可将光伏阵列与储能电池输出的直流电逆变为交流电用以并网。本研究通过逆变器数学模型分析,提出模型预测控制,但单矢量MPC(模型预测控制)算法存在控制误差较大的问题,这会导致预测电流与参考电流产生偏离,从而产生较大电流波纹。针对单矢量MPC算法存在的问题提出双矢量MPC算法。最后对单矢量、双矢量MPC逆变器建模仿真分析,验证双矢量MPC算法的优越性。Inverter is an important part of photovoltaic power generation integrated into the grid.Through the inverter,the direct current output by photovoltaic array and energy storage battery can be converted into AC power for connection to the grid.This paper analyzes the mathematical model of the inverter and puts forward the model prediction control,however the single vector MPC(model prediction control)algorithm has the problem of large control error,which will lead to the deviation between the predicted current and the reference current,resulting in large current ripples.Two-vector MPC algorithm was proposed to resolve the problems existing in single vector MPC algorithm.Finally,the modeling and simulation analysis of the one-vector and two-vector MPC inverter was conducted to verify the superiority of the two-vector MPC algorithm.
