2.1. Principles of Hybrid Energy Storage Participation in Grid Frequency Regulation In grid frequency regulation, a standard target frequency is typically set to 50 Hz. The grid frequency is then modulated by adjusting the rotational speed of generators to manage the power output .
In this paper, we investigate the control strategy of a hybrid energy storage system (HESS) that participates in the primary frequency modulation of the system.
The hybrid energy storage capacity allocation method proposed in this article is suitable for regional grids affected by continuous disturbances causing grid frequency variations. For step disturbances, the decomposition modal number in this method is relatively small, and its applicability is limited.

563 Abstract: The application of virtual synchronous generator (VSG) control in flywheel energy storage systems (FESS) is an effective solution for addressing the challenges related to reduced inertia and inadequate power supply in microgrids.
The virtual synchronous generator (VSG) technology imparts power to electronically interfaced equipment with inertia and damping features akin to synchronous generators (SGs), thereby offering an effective solution to the challenge of insufficient frequency support capacity resulting from the reduced share of SGs .
In, a fuzzy VSG control structure was designed for the FESS, thereby enabling the automatic adjustment of the VSG Tianyu Zhang et al. Adaptive VSG control of flywheel energy storage array for frequency support in microgrids 565 parameters according to the magnitude of the perturbation.
In Case III, the FESA reduced its output power during the frequency recovery phase to extend its operating time. However, this adjustment caused a secondary drop in grid frequency, leading to oscillations in the FESA output power.
The frequency of the ideal AC grid was set to 49.97 Hz. Fig. 12 illustrates the output power and SOC of the FESA during standby periods. As shown in Fig. 12 (a), traditional VSG control results in the FESA continuing to output active power within the frequency-regulation dead zone.
Therefore, the output active power of the VSG can be expressed as Pe = 3 sinE Uv g XΣ δ (7) where Ug is the grid voltage, XΣ is the equivalent impedance of the line and the virtual impedance of the VSG, and δ is the phase angle difference between the output voltage of the VSG and the grid voltage.
This paper presents a coordinated control of an ESS with a generator for analyzing and stabilizing a power plant by controlling the grid frequency deviation, ESS output power response, equipment active power, and state of charge (SoC) limitation of the ESS in a power.

The high proportion of renewable energy access and randomness of load side has resulted in several operational challenges for conventional power systems. Firstly, this paper proposes the concept of a flexi.
Firstly, this paper proposes the concept of a flexible energy storage power station (FESPS) on the basis of an energy-sharing concept, which offers the dual functions of power flow regulation and energy storage. Moreover, the real-time application scenarios, operation, and implementation process for the FESPS have been analyzed herein.
The energy storage output is utilized to compensate for the insufficient frequency regulation capacity of thermal power, thereby reducing their wear. The power of energy storage is constrained by the SOC to minimize the number of energy storage cycles and improve its overall life. 3. Loss model of ESCTPFR

During the three time periods of 03:00–08:00, 15:00–17:00, and 21:00–24:00, the loads are supplied by the renewable energy, and the excess renewable energy is stored in the FESPS or/and transferred to the other buses. Table 1. Energy storage power station.
Under the influence of SOC planning, the energy storage stations in Strategy 5 follow the SOC recovery sequence of “higher SOC leads to higher discharge power, while lower SOC leads to higher charging power.” As a result, the SOC of the ESS tends to shift towards 0.5.
During the period 10:00–17:00, the load is supplied by the renewable energy, and the excess renewable energy is stored in the FESPS and subsequently transferred to the other buses. During the period 20:00–22:00, the load is separately supplied by the energy storage.
