This paper deals with a photovoltaic system implementation, which is connected to the three-phase four-wire utility grid by means of three full-bridge single-phase PWM inverters. Simultaneously, with its capability for injecting active power into the grid, the photovoltaic system performs both reactive power compensation and harmonic current suppression of the load. The proposed algorithm adopted to obtain the current references of the PWM inverters is based on the synchronous reference frame theory, which is implemented in conjunction with a proper maximum power point tracking technique. Simulation results are presented in order to validate the proposed control strategy.
