Wu, Y. (author), Soeiro, Thiago B. (author), Shekhar, A. (author), Xu, J. (author), Bauer, P. (author)LCL filter is widely adopted for strict standard compliance of grid-tied voltage source converters (VSCs). The third order low-pass filtering provides great attenuation for the high frequency harmonics generated by the power electronics guaranteeing low output currents noise injection into the grid.
