Abstract :
With the growing of distributed generation penetration which feeds single-phase linear and/or nonlinear loads, the utility power quality is affected in terms of low power factor and current harmonics. In this paper, a single-phase DG unit is connected to the grid via a multifunctional converter. The converter exchanges the power with the loads and/or the grid in addition to improving the power quality by acting as a shunt active power filter. A predictive current control technique is used without using a phase locked loop. The proposed system performance is investigated at different operating conditions using a MATLAB/SIMULINK simulation model.
