A distributed zero-error frequency regulation control method based on consensus algorithm is proposed in order to improve the microgrids’ frequency quality when operated in islanded mode. Each inverter utilizes its local and neighbors’ active power information and combines with the weighted average consensus iterative algorithm to realize active power and frequency control. The weight matrix is determined by the local-degree weights method. This strategy could realize zero-error frequency regulation and also guarantee proportional active power sharing among inverters according to the rated power capacities. A microgrid simulation model which includes five inverters is built using Matlab/Simulink. The proposed strategy is used and the simulation results show its correctness and effectiveness.
