Power quality improvement based on p-q theory using photovoltaic arrays

This paper represents, a photovoltaic system connected to a three phase grid. The model comprises PV array, dc-dc boost converter and inverter. The novel control technique applied is based on p-q theory to trigger the inverter. Phase Locked Loop is used to synchronise the inverter output with grid. In this paper the control technique is proposed, which introduces simple algebraic calculations.
