Abstract:
Microgrids play a vital role in future distributionnetworks. In this regard, dispatching the generation & unitcommitment strategies are not directly applicable to this kind ofgeneration/demand structure. Transmission systems as part ofthe conventional power systems have mature strategies fordispatching and especially remedies to cope with congestions incritical paths. In this paper, it is assumed that the maindistribution system is composed of different individualmicrogrids as single identities connected to the distribution grid.Congestion management is of primary concern in the tie linesconnecting the microgrids to the utility grid or between themicrogrids. Back-to-back Voltage Source Converters (VSCs) asan interfacing facility is used to cope with the congestion in theinterconnecting lines. Thyristor Controlled Series Capacitor(TCSC) is also proposed as the controlling device to manage thecongestion. Other strategies like using a central controller withcommunication links to the microsources in order to dispatchremedial actions is also proposed; and ultimately optimalswitching of the existing paths are used to mitigate thecongestion.
