Abstract

This paper provides guidelines for the MATLAB-based simulation and dSPACE-based real-time implementation of predictive current control scheme for grid-connected two-level voltage source converters. A step-by-step procedure for the calculation and extrapolation of reference grid currents, and design of predictive model and cost function is provided. The predictive model uses grid voltages, grid currents, DC voltage, system parameters, and discrete-time mathematical model of the system to calculate the future values of grid currents. The cost function evaluates the error between reference and predicted grid currents and selects an optimal switching state based on the minimum error value. The proposed design and implementation approaches are validated by the simulation and experimental results. This paper serves as a valuable reference for novice readers in the model predictive control area.
