要約(英語): In the recent microgrids (MGs), due to rapidly introduced distributed generators (DGs), synchronization power and tie power between multiple microgrids (MGs) are difficult to analyze accurately. For this reason, we introduce a method to support the frequency of multiple MGs using an extended virtual synchronous generator (EVSG) in each microgrid (MG). The proposed EVSG controller has not only governor free control (GFC) but also secondary control equivalent to load frequency control (LFC). A point to be noted here is to set parameters so that the existing secondary control in each MG and the secondary control in the EVSG do not interfere with each other.
