Based on the IEEE standards, distributed generation (DG) resources should not be operated over the critical situations in the interconnection power grid, because of the network instability considerations. These standards are severe restrictions for passive defense implementation in the power systems. In this paper, a new algorithm for employment of the micro grids equipped with the Gas Turbine Synchronous Generators (GTSG) is proposed. In an islanded distributed network, consumption and generation in the micro grids have a vital role. In this paper, two different types of load shedding methods, namely, traditional and intelligent methods are simulated considering frequency and derivative of the frequency in the system. Furthermore, according to the load and generation situations, "load shedding" and "changing the mode of the GTSG governors" are used as two different tools to prepare a robust stability in the system. Load following service is another subject which is studied in this paper. The proposed model has been applied to the load profile of an actual system using DIgSILENT software. The results show that over the critical conditions, operation of the DGs in the islanded mode is possible and reliable.
