Stability, power sharing, & distributed secondary control in droop-controlled microgrids
2013 IEEE International Conference on Smart Grid Communications (SmartGridComm)
Motivated by the recent and growing interest in microgrids, we study the operation of droop-controlled DC/AC inverters in an islanded microgrid. We present a necessary and sufficient condition for the existence of a synchronized steady state that is unique and locally exponentially stable. We discuss a selection of controller gains which leads to a sharing of power among the generators, show that this proportional selection enforces actuation constraints for the inverters. Moreover, we proposedoi:10.1109/smartgridcomm.2013.6688036 dblp:conf/smartgridcomm/Simpson-PorcoDBSG13 fatcat:brm6uty3ifgqpim5fiitax3foa
