In recent times, microgrids are marking their presence with the electrical grid. They are capable of meeting increased load demand, alleviate transmission line stress, support carbon emission reduction, and reduce feeder losses. Their unique capability to operate under grid connected as well as islanded mode of operation makes them more desirable. When connected in islanded mode, stability of grid and sharing of power among parallel connected distributed units are an important concern. Presence of nonlinear, unbalanced load, line impedance mismatch, harmonic current circulation, etc., makes controlling of microgrids a difficult task. Various communication based and communicationless control techniques have been proposed by researchers. This paper reviews droop control techniques for controlling of parallel connected converters and also mentions important features of each control technique.
