Traditional droop control is difficult to guarantee the power distribution accuracy of parallel micro sources in islanded microgrid and

at the same time

such problem as busbar voltage drop and low supply voltage quality are existed. As for the above problem

a kind of distributed control method based on consensus algorithm is proposed. Low bandwidth communication is implemented between adjacent micro sources. The average voltage of the system is interactively calculated with the local information from each micro sources itself and other micro source information with combination of discrete consistency

the PI controller is added in the P-V control loop and the average voltage of the system is used to achieve the reasonable distribution of active power

improve the quality of system voltage and achieve voltage regulation. As for the islanded microgrid system with four sets of micro sources

the simulation model is set up by Matlab/Simulink so to simulate

compare and analyze. The superiority of the proposed control strategy in power distribution and voltage adjustment is verified by the simulation result.
