Abstract
Based on the topology of five level nested neutral point clamped (NNPC) grid connected inverter, this paper compares two type of finite control set model predictive control (FCS-MPC) methods to reduce the amount of calculation time compare with the traditional FCS-MPC. The first method is based on space vector modulation approach which uses 60- degree voltage state vector for the prediction to reduce the calculation time of each control period in FCS-MPC algorithm. While the second method is to simplify the calculation time by using the FCS-MPC based on adjacent state vector method. Through comparative analysis, it can be seen that the 60 degrees sector FCS-MPC have similar performances regarding the current THD; the upper and lower DC voltage deviation of DC- link capacitors. The main difference is on the computation time which results to 35 control periods compare to 125 for the traditional FCS-MPC. The adjacent state vector method results to 7-29 control period.
