design of controller and lcl filter for a three-phase pv grid-connected inverters

The need for a clean environment, along with the increasing demand for energy consumption, has caused the need to expand the generation of energy from renewable energy sources (ress). among various ress, photovoltaic (pv) systems can create a balance between the increase in demand and clean production. however, designing the proper controller and lcl filter for three-phase pv grid-connected inverters is challenging. in this paper, a controller with the lcl filter for a grid-connected pv system is designed. the design is confirmed by simulations using matlab software. results prove the effectiveness of the suggested approach.
