روش تشخیص جزیره سازی جدید برای ریز شبکه های بر مبنای درج امپدانس متغیر

In this paper, an islanding detection method (IDM) is proposed that is based on the insertion of a suitable, variable impedance at the low voltage side of the Grid. Islanding detection is effected by an intelligent agent embedded into the Microgrid's Central switch, which is transformed to a hybrid automatic transfer switch (HATS). The HATS agent detects the operation mode of the Microgrid based on local measurements and supervises the grid status. Both simulation studies and hardware laboratory tests are presented showing the performance and feasibility of the proposed method.
