Abstract This work proposes an adaptive underfrequency load shedding (AUFLS) method suitable for power systems with high penetration of renewable energy sources (RES) and energy storage systems (ESS). The proposed AUFLS method takes into account the impact of these devices in the load shedding execution, considering important characteristics, such as the synthetic inertial response and the limited capacity of the ESS. In addition, the proposed approach combines into a single process different features of AUFLS methods already presented in the technical literature. Different scenarios of a modified version of the IEEE New England system is used to evaluate the proposed method and to compare its performance with other load shedding techniques. The results show that the proposed AUFLS is able to better estimate the generation deficit, resulting in a more precise and robust load shedding scheme.
