“…Our model offers a versatile and substantially improved approach for analyzing risks and drivers of grid frequency stability. Previous data-driven studies analyzed the impact of one external feature on grid frequency fluctuations based on linear correlations [9][10][11] or conditional probabilities. 7 Such univariate analyses cannot be adjusted for effects of other features, which could be correlated with the feature of interest and may lead to incorrect conclusions (cf.…”

“…Consequently, each generator's capacity increases to compensate for the generation decraese as efficiently as possible, as depicted in figure (12). In figure (13), it is observed that the load buses voltage would be decrase, It is dip about (0.05 pu). In this scenario, the standard power system was operated in a stable state.…”

“…If we have a better understanding of how the frequency of the power grid behaves and what factors can cause it to deviate, we can develop better control strategies to keep the grid stable. This could help to reduce the risk of blackouts and other disruptions to the power supply [13].…”

Maintaining the stability of an electrical power system necessitates imposing stringent operational boundaries on grid frequency. Variations and external influences have the potential to induce significant frequency shifts, thereby necessitating heightened control measures. Power systems typically function at a frequency of 50 Hz. Nevertheless, disruptions such as generation loss, abrupt load surges, or system faults can lead to disturbances and deviations, ultimately destabilizing the frequency of these electrical power systems. Consequently, there is a necessity to investigate and enhance the frequency stability of electrical power systems in the face of such disturbances. In this paper, a standard Institute of Electrical and Electronics Engineers' (IEEE) 9-bus system that simulated in MATLAB-Simulink was used, with the amount of generation is decreasing in the first scenario, and the second scenario, when the load is more than the available generation. Both Scenarios cause dropping the grid frequency. The results demonstrate the behavior of power systems under normal and abnormal conditions and stability margin limits.

“…c) Normal operation: during most of the time, the grid only experiences small power imbalances, which cause the grid frequency to fluctuate around its nominal value. These fluctuations are depending on the grid inertia and vary therefore with the share of wind power on the power production [27]. Measurements of the grid frequency in Ireland during high wind power production [28] are used for the normal operation scenario.…”

Grid frequency support by wind turbines is increasingly demanded by grid operators around the globe. By meeting these requirements, the wind turbines leave their optimal operating point and may even be pushed out of their safe operating range during severe grid events. In the past years, the Wind Energy Technology Institute developed a controller for grid frequency support in collaboration with Suzlon Energy. This work seeks to improve this controller by adding a pitch angle adjustment depending on the operating point of the wind turbine and the power adjustment for grid support. The controller performance is analysed for three scenarios and for the whole operating range of the NREL 5 MW WT. Simulations show, that the adjustment lowers the risk for overspeed at the cost of an increased pitch rate. By contrast, the aerodynamic efficiency is not increased by the additional control loop. The effect on the tower depends heavily on the wind situation during and shortly after the grid frequency support event.
