A microgrid is a new concept that has changed the power systems dramatically. This paper focuses on the autonomous operation of an Islanded inverter. The manuscript deals with the design of micro grid in island mode. There are several methods to control a microgrid. Among them droop control deals with change of active and reactive power to change in frequency and supply voltage respectively. The aim is to design an island mode inverter and to study its changes in active and reactive power with frequency and voltage in MATLAB while the load is resistive and nonlinear in nature. Also, contrive a voltage quality controller to improve the voltage harmonics and to achieve tight output voltage regulation through the implementation of a special notch filter in the controller algorithm.
