Solar Grid-Connected Three-Phase System With Active And Reactive Power Control And Input Voltage Clamped

Abstract

This paper presents a model of the three-phase PWM inverter and a control strategy using dqO transformation to be employed in a grid connected photovoltaic generation system. The proposed system operates as an active filter capable of compensate harmonic components and reactive power, generated by the other loads connected to the system. To control the power between the grid and photovoltaic system it is proposed the input voltage clamping of the inverter technique, where it is intended to achieve the maximum power point operation. Following, simulation results and analyses are presented to validate the proposed methodology for grid connected photovoltaic generation system.
