This paper enhances a self‐adjusting droop control strategy further to achieve an improved voltage profile in a microgrid along with proportional reactive power sharing amongst its sources. The proposed enhancement consists of an additional term in the “self‐adjusting” nominal voltage. The proposed strategy is entirely decentralised and does not require information about the feeder impedance or the network topology. The proposed technique is robust and found to improve the voltage profile and the reactive power sharing for radial, meshed as well as reconfigured microgrid networks. Simulation studies have been performed on two test microgrids to assess and compare the performance of the proposed strategy. Experimental validation to confirm further the viability of the proposed strategy for several topological structures of the microgrid is done on a laboratory‐scale microgrid.
