Abstract

Distributed power systems are getting more attention now-a-days due to their high flexibility and reliability. In this paper, predictive current control strategy is proposed for the grid-connected four-leg inverters. This kind of converter is developed to deliver power to the unbalanced/nonlinear three-phase loads and as well to the grid. The discrete-time model of the converter and load is used to predict the future behavior of the load currents for each valid switching state. The control method chooses a switching state that minimizes the error between the output currents and their references. The feasibility of the proposed method is verified by computer simulations, showing a good performance and capacity to compensate the disturbances.
