Several non-linear loads are connected to the low voltage public grid, for example: compact fluorescent lamps (CFL) or electronic devices contain switched mode power supplies (SMPS) and diode rectifiers. These distort the grid with current harmonics therefore the grid voltage waveform become distorted. We worked out a new current control strategy for grid-connected inverters of domestic power plants...
This paper proposes a three-phase four wire current-controlled Voltage Source Inverter (CC-VSI) for both harmonic mitigation and PV energy extraction. For harmonic mitigation, the CC-VSI works as a grid current-controlling shunt active power filter. Then, the PV array is coupled to the DC bus of the CC-VSI. The MPPT controller employs the Fibonacci search method. The output of MPPT controller is a...
