The analysis of large-scale system emergencies revealed disadvantages in the current Under Frequency Load Shedding (UFLS) Schemes of European energy systems. Disadvantages of the UFLS schemes arose due to distributed generation (DG), the more significant part of which is made up the renewable energy sources. As it turned out that the UFLS have disconnected part of the load and DG simultaneously with the same UFLS relay. From the analysis of the emergencies, it was concluded that did not the DG factor in the distribution network into account full. The total load shedding was determined without taking into account the change in DG generation. The settings of the UFLS relays were selected based on the data of one mode, namely, based on the mode of the total peak demand of the power system. In the paper analyzed the parameters of the UFLS scheme and the time when the power is measured at the UFLS relays in the Power System of Ukraine. On a real microgrid scheme, it was shown that the total load shed UFLS will decrease with an increase in the share of DG capacity.
