Abstract

Due to the wide spread of power electronics equipment in modern electrical systems, the increase of the harmonics disturbance in the ac mains currents has became a major concern due to the adverse effects on all equipment. Power electronic converters are commonly used for interfacing distributed generation (DG) systems to the electrical power network. In DG systems a fast and accurate positive-sequence, fundamental grid-voltage frequency and magnitude tracking is required to synchronize grid connected converter-systems with the mains. This paper deals with a single phase inverter for DG systems requiring power quality features, such as harmonics and reactive power compensation for grid-connected operation. The idea is to integrate the DG unit functions with shunt active power filter capabilities. With this approach the inverter controls the active power flow from the renewable energy source to the grid and also performs the nonlinear load current harmonic compensation. The effectiveness of the proposed method is investigated using a detailed mathematical analysis. In particular, active power control plays an important role both during grid faults and in normal conditions. The usefulness of the simulation approach to APF is demonstrated so APF designers have a better insight using Matlab Simulink in order to develop new APFs.
