Performance Improvement of Distribution System Through PV Inverter

In rural area's distribution system reliability is very poor due to frequent load shielding. In order to improve the system reliability, power electronics devices (converters) are used to connect renewable energy sources to obtain the maximum output from the grid-interfacing converter scheme presented in this paper. To inject power to grid from solar side, inverter is used and Filter is used for compensation of neutral load current and unbalance current. Verification of this system is done by using MATLAB/Simulink simulation and results are validated.
