Distributed Energy Generation is one of the solution to meet the growing energy demand.
Distributed energy generation mostly involve renewable energy sources such as solar and wind.
These renewable energy resources uses technologies that are clean and green and also reduce
the use of fossil fuels that are depleting at a faster rate. The Renewable Energy Sources (RES)
are connected to the grid using grid interfacing inverters. The use of power electronic devices
and also nonlinear loads has lead to power quality issues. In this paper the control for grid
interfacing inverter is done using PI and Fuzzy logic controller. The inverter acts as
multifunction device by transferring the power generated from Renewable energy Sources to
the grid also as a shunt active power filter to mitigate Harmonics. Simulations are done using
MATLAB/ SIMULINK Software.
