Performance assessment of different droop control techniques in an AC microgrid

The objective of this paper is to evaluate the performances of different droop control technologies that are proposed in literature for the real-time power balancing in a microgrid. Mainly, the decentralized droop control techniques are studied. The different attributes of the droop control are identified. Droop controllers are synthesized by considering all possible cases of an attribute. The generalized control architectures are presented based upon the broad classification of droop controllers. Extensive case studies are performed to verify the pros and cons of the selection of a particular feature in the droop controller. Both the transient and steady-state performances are evaluated.
