摘要

Power converters are essential for allowing increasingly more solar energy to be connected to power systems. In this paper, a model predictive control of a three-phase 7-level CHB multilevel inverter for solar energy injection is developed, using the incremental conductance algorithm for establishing an MPPT strategy which maximises PV energy from the system. In order to prove the proposed control scheme, simulations in MATLAB/Simulink are carried out. The predictive current control strategy, the dc voltage control, and the MPPT controller proved proper steady state operation and proper response in front of external disturbances. Thus, solar energy injection to the grid can be maximised using the proposed 7-level CHB multilevel inverter.
