外文摘要：This paper develops a distributed frequency control for renewable microgrids through communication networks subject to disturbances。 The proposed distributed cooperative control， consisting of distributed primary control and secondary control， will synchronize the frequency of microgrids to the desired values and through a sparse communication network subject to disturbances， that is to say， considering asymmetric communication delays and noise disturbances。 Distributed cooperative controllers are designed into the secondary control stage for renewable microgrids， in which manner the criteria for the stability analysis and delays boundedness to maintain the system stable are derived。 With the proposed algorithms， control derivation of frequency produced during the primary control stage can be well remedied even if the communication delays and noise disturbances may exist。 The effectiveness of the proposed control methodology is verified by the simulation of a renewable microgrid system in MATLAB/SimPowerSystems。
