Challenges of frequency regulation in modern power systems Frequency regulation, a method for assessing grid stability following a disturbance or fault, is evaluated by considering frequency nadir, steady-state deviation, a dynamic rolling window, and the rate of change of frequency.
2.2. Frequency regulations methods for power systems with RESs Due to their high level of unpredictability, intermittent nature, and nonlinear power system connectivity, RESs such as wind energy bring technological hurdles to energy systems.
The energy storage (ES) stations make it possible effectively. However, the frequency regulation (FR) demand distribution ignores the influence caused by various resources with different characteristics in traditional strategies.
These challenges encompass power quality issues, supply–demand imbalances, frequency deviations and other challenges . Energy storage system is an optional solution by its capability of injecting and storing energy when it is required.
Energy storage systems have emerged as an ideal solution to mitigate frequent frequency fluctuations caused by the substantial integration of RES.
The development and commercialization of energy storage technology will have a significant impact on power system in terms of future system model . In recent years, both engineering and academic research have grown at a rapid pace, which lead to many achievements.
