Efficient single phase power factor improvement strategy for microgrid operation

A strategy to improve the power factor (PF) at the point of common coupling (PCC) for microgrid applications is presented in this paper. The position of the compensating unit is selected to correct the power factor and reduce the harmonic levels of the grid current and PCC voltage in microgrid connected distributed renewable energy sources. The proposed compensation system for power factor improvement (PFI) can be operated dynamically for both linear and nonlinear loads. Fast and efficient algorithm for phase detection in the presence of harmonics has been incorporated to the proposed system. Finally simulation and experimental results are presented to verify the effectiveness of proposed compensation unit.
