To leverage the efficacy of different types of energy storage in improving the frequency of the power grid in the frequency regulation of the power system, we scrutinized the capacity allocation of hybrid energy storage power stations when participating in the frequency regulation of the power grid.
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.
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 .
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.
To make up for the aforementioned defects, we propose here a capacity configuration method for hybrid energy storage stations based on the northern goshawk optimization (NGO) optimized variate mode decomposition (VMD).
Currently, there have been some studies on the capacity allocation of various types of energy storage in power grid frequency regulation and energy storage. Chen, Sun, Ma, et al. in the literature have proposed a two-layer optimization strategy for battery energy storage systems to regulate the primary frequency of the power grid.

As India's power grid becomes increasingly complex due to rising renewable energy penetration, the need for a stable grid has never been more pressing.
Energy storage must remain a priority in India's broader strategy to achieve carbonization across all sectors, from transportation to industry. India's renewable energy aspirations hinge on the widespread deployment of battery energy storage systems.
As of March 2024, India has reached a significant milestone with its cumulative installed energy storage capacity at 219.1 MWh, or approximately 111.7 MW. This achievement underscores India's strong commitment to advancing energy storage technologies and enhancing its energy infrastructure.
India's peak energy demand often exceeds the supply capacity, especially during evening hours when solar generation ceases. Energy storage solutions for renewable energy bridge this gap by storing surplus energy generated during the day and releasing it during high-demand periods. 2. Strengthening Grid Stability

Single artificial intelligence forecasting methods, such as CNNs and LSTMs, often exhibit certain limitations in power grid load forecasting. Due to their fixed model structures, these methods may only perform well on specific types of load data and poorly predict complex, nonlinear load data.
After gradually incorporating these attention mechanisms, key performance indicators (MAE, RMSE, and Max Error) showed significant improvements. This demonstrates that the proposed attention mechanisms work synergistically to significantly enhance the accuracy and robustness of power grid load forecasting.
Power grid load data exhibit complex spatial and temporal dependencies, requiring robust models with strong expressive power. The proposed model integrates CNN, LSTM, and multiple attention mechanisms to explore load data from different dimensions.
Therefore, combining CNN with LSTM allows the strengths of CNN in local feature extraction to be integrated with LSTMs' strengths in temporal modeling, enabling the model to effectively capture both local features and long-term dependencies in load data. This enhances the accuracy and robustness of power grid load forecasting.
This model aims to address the issue in traditional methods where complex temporal features and important information in power grid load data are not fully captured.

Base station operators deploy a large number of distributed photovoltaics to solve the problems of high energy consumption and high electricity costs of 5G base stations.
The deployment of distributed photovoltaics in the base station can effectively promote the construction of a zero-carbon network by the base station operators. Table 3. Comparison of the 5G base station micro-network operation results in different scenarios.
Therefore, 5G macro and micro base stations use intelligent photovoltaic storage systems to form a source-load-storage integrated microgrid, which is an effective solution to the energy consumption problem of 5G base stations and promotes energy transformation.
When the base station operator does not invest in the deployment of photovoltaics, the cost comes from the investment in backup energy storage, operation and maintenance, and load power consumption. Energy storage does not participate in grid interaction, and there is no peak-shaving or valley-filling effect.
Distributed PV generation offers flexible access and low-cost advantages. Integrating distributed PV with base stations can not only reduce the energy demand of the base station on the power grid and decrease carbon emissions, but also effectively reduce the fluctuation of PV through inherent load and energy storage of the energy storage system.
Access to the 5G base station microgrid photovoltaic storage system based on the energy sharing strategy has a significant effect on improving the utilization rate of the photovoltaics and improving the local digestion of photovoltaic power. The case study presented in this paper was considered the base stations belonging to the same operator.
