Impact of Communication Delays on Secondary Frequency Control in an Islanded Microgrid PROJECT TITLE :Impact of Communication Delays on Secondary Frequency Control in an Islanded MicrogridABSTRACT:Low-bandwidth Communication channels are used to support the data exchange between a microgrid centralized controller and local controllers in the secondary frequency management of an islanded microgrid. But, the impact of the inherent time delay in these Communication channels on the microgrid performance has not been taken into consideration when the secondary frequency controller is meant. This paper investigates the impact of the Communication delays on the secondary frequency management of an islanded microgrid with multiple distributed generators. A small-signal model-based methodology is introduced for the microgrid to find delay margins below which the microgrid will stay stable. By performing a series of trial studies, the relationships between secondary frequency control gains and delay margins are obtained. A gain scheduling approach is also proposed to compensate the result of the Communication delay on the secondary frequency control. Results from the Canadian urban distribution system have verified that Communication delays can adversely affect the microgrid secondary frequency control, and also the proposed gain scheduling approach can improve the robustness of the microgrid secondary frequency controller to Communication delays.
