Review of inverter control algorithms in Grid-integrated Solar Photovoltaic system

The shift to green energy has proved to be a feasible alternative to satisfy the increasing energy needs of the developing world, as dependence on conventional energy supplies has been significantly reduced. In particular, solar energy remains one of the best green energy options available because it's plentiful, clean and efficient. Owing to its DC nature, an inverter is an indispensable component of solar photovoltaic (PV) systems. The function of the inverter conversion of generated DC into AC power along with synchronization to the grid for hassle-free connection with the assurance of high power quality. So, being an inevitable part have driven the development towards low cost, high efficiency, high reliability and high tolerance topologies. However, the control algorithm places a significant role in enhancing system power quality and efficiency along with the topology. This paper presents a detailed review of the various control structures employed in a grid-integrated solar PV system.
