LCL filter design with passive damping for photovoltaic grid connected systems

In photovoltaic grid connected systems. An LCL filter is often used to interconnect an inverter to the utility grid in order to filter the harmonics produced by the inverter. This paper proposes design methodology of an LCL filter topology to connect an inverter to the grid, an application of filter design is reported with m-file in Matlab. The LCL filter with passive damping allows to remove the peak near the resonance frequency,
