Energy systems based on photovoltaic (PV) cells have increased at a rapid pace. Therefore, power converters have been widely employed in power systems to enhance the quality and magnitude of the power drawn from renewable energy sources. An LCL filter for connection of an inverter to the grid is often used to reduce harmonics generated by the inverter. According to different design techniques, optimal parameters of LCL filter tend to vary in a wide range. This paper presents a new approach to
