Abstract
In recent years, with the advancement of technology in the field of power electronics, most of the loads are nonlinear in nature. The current harmonics for such types of loads may not necessarily be below the prescribed value of 5% according to the IEEE-519 grid code. Harmonic compensation required for such types of nonlinear loads may be achieved with the help of compensators such as shunt active power filter (SAPF). Generally SAPF is connected at the point of common coupling (PCC) between the gird and the PVDG system for harmonic compensation. But, such a system leads to an increase in the cost as well as complexity of the overall system. In this paper, the shunt APF has been integrated with the inverter for compensation of current harmonics for the nonlinear load. The inverter is controlled with the help of a reference current that has been generated using the widely acknowledged instantaneous reactive power theory. The switching pulse to the inverter will be given in such a manner that the inverter will generate the current harmonics required by the load. The objective is to integrate power quality enhancement technique in the Photovoltaic inverter so that it does not require an additional active power filter in the point of common coupling for power quality improvement. Also the inverter can be used to supply power to grid.
