Design and control of LCL filter interfaced grid connected solar photovoltaic (SPV) system using power balance theory
The grid connected PV system is considered in this paper with line impedance consideration. The PV is interfaced using LCL filter and simple design equation for LCL filter is considered. The power balance theory control strategy is implemented with different computation equation. The system is analyzed and investigated under different load conditions. The overall system parameters and configuration mentioned with improved THD.
