Grid connected solar photovoltaic system with Shunt Active Filtering capability under transient load conditions

This paper discusses about the active filtering capability that can be incorporated in grid connected photovoltaic systems by proper control of the grid interfacing inverter. Improved Linear Sinusoidal Tracer Algorithm is used for generating the reference signals to control the inverter so that the system feeds the available photovoltaic energy into the grid, provides reactive power compensation and harmonic elimination of the loads connected at the point of common coupling. The controller is tested in MATLAB/SIMULINK for linear and nonlinear loads. The simulation results demonstrate the efficient working of grid connected photovoltaic system as Shunt Active Filter.
