Nonlinear Unbalanced Load Compensation for PV Sourced Grid Connected Inverter

Abstract:

The major problem in the PV system is the poor PV consumption under viable irradiation condition. So in order to improve the power consumption of PV along with grid connected inverter, this system has been implemented with controller analysis and model. This system is mainly used for non linear load compensation under unbalanced condition. In the existing method, Peak current of the inverter is reduced during the unbalanced grid-voltage sags with the help of current harmonics injection which increases the total harmonic distortion. Double synchronous reference frame technique with PLL is used to synchronize PV with grid. As well as the maximum power point of PV is tracked using Incremental Conductance technique to reduce the error and improves the system efficiency. Selected simulation results using MATLAB/Simulink are reported in order to show the proposed system efficient.
