چکیده :

In distributed networks, protective procedures are highly substantial. Todays, load shedding is more beneficial in terms of stability margin increment of voltage and frequency in microgrids. This paper presents a segmentation-based hierarchical method (SHM) aimed to simultaneously recover voltage and frequency to their allowable domain in front of disruptive incidents. In the SHM, in order to specify the adequate mount of elimination load following disruptive incidents and uncertainties, a combinational study based on the system topology and the relationship between voltage and active power. According to the proposed method, achieving accurate results quickly requires the segmentation of the system into several regions from two standpoints pinpointed above and the determination of a master-bus in each region. In the following, the SHM will be simulated on a modified IEEE 37-bus distribution network, and the results will imply the accuracy of presented scheme accompanied with increasing the system safe margin and eliminating the possibility of system collapse.
