“…Reference [9] introduces a unified metric based on the physical characteristics that quantify the initial and sustaining energy that can be used to provide FFS to the grid. Reference [10] shows that inertial and droop metrics can demonstrate FFS ability after analyzing the features of the generation unit. Reference [11] proposes a quantitative index of frequency support capability based on the frequency safety binary table through the study of analytical modeling of wind turbines.…”

Modern power systems include synchronous generators (SGs) and inverter-based resources (IBRs) that provide fast frequency support (FFS) to the system. To evaluate the FFS ability of both SGs and IBRs under a unified framework, this paper proposes a method that evaluates the FFS ability of each generation unit via its dynamic trajectories of the active power output and the frequency following a contingency. The proposed method quantified FFS ability via two indexes, namely, the equivalent inertia constant and the equivalent droop, of each generation unit. The Tikhonov regularization algorithm is employed to estimate the FFS ability indexes. The New England 10-machine system serves to validate the feasibility and accuracy of the proposed method and illustrate the different FFS ability of the grid−forming and grid−following IBRs.

“…The simulation results demonstrate a link between inertia and damping in various operational scenarios. In [5], it is analyzed that by controlling the power retained by capacitors on the direct current side, the droop control of a rate of change of frequency (RoCoF) helps to dampen frequency fluctuations that can cause problems and also classifies the control time-frame and inertia which helps in reducing the frequency variation. The study [6] addresses frequency control challenges in micro-grids caused by erratic renewable energy source (RES) outputs.…”

The integration of renewable energy sources (RES) into DC-distributed power systems (DC-DPSS) is gaining traction as a sustainable energy solution. However, the inherent variability of RES output can introduce instability into the grid, posing challenges for maintaining system reliability and stability. Fuzzy logic controllers (FLCs) have emerged as a promising approach to mitigate these instability issues, offering a robust and adaptable control strategy that can effectively handle the complexities of DC-DPSS. This paper examines the application of FLCs in DC-DPSS, exploring their effectiveness in addressing instability caused by RES fluctuations. FLCs are a control system that leverages fuzzy logic, a form of logic that utilizes linguistic variables to represent uncertainty, make decisions, and improve the stability of DC-distributed power systems. The research analyzes various system parameters, including inertia, damping, and synchronization characteristics, using a static synchronous generator (SSG) model. The study builds upon prior findings by adding a fuzzy logic controller to the existing system. The results showed better performance which resulted in improved inertia, damping, and synchronization characteristics. The efficiency of the proposed controller is demonstrated using MATLAB/Simulink.

“…Different researchers have discussed the concept of droop control in power systems. The authors in [5] proposed a droop control based on RoCoF which support the frequency change by controling the DC side capacitor. A combined droop and virtual inertia control study are proposed in reference [6] for a wind farm that operates under underload and overload conditions.…”

Inverter-based resources (IBR) have been widely studied for their advantages on the current power systems. This increase in the penetration of renewable energy has raised some concerns about the stability of the existing grid. Historically, power systems are dominated by synchronous generators that can easily react to system instability due to high inertia and damping characteristics. However, with IBR, the control of the inverter plays a crucial role in contributing to the system stability and enhancing the functionality of the inverters. One of these novel control methods is droop control. Droop characteristics are used to control voltage, frequency, and active and reactive power. This paper presents the impact of frequency droop damping on system frequency, real power, and the rate of change of frequency with distributed energy resources. Also, battery sizing is suggested based on the results. The results also show the need for optimal selection for the frequency droop damping to fulfill the appropriate battery size in terms of cost and performance. The simulations are carried out in an electromagnetic transient program (EMTP).
