HongPower Explores Grid-Based Energy Storage Trends at 2025 Seminar

On March 4, 2025, the 2025 China Energy Storage Technology Innovation and Application Seminar, hosted by Polaris Power Grid and Polaris Energy Storage Network, was grandly opened in Hangzhou, Zhejiang. This conference focused on the development trend of energy storage technology and brought together technical experts from China Energy Group, State Grid, Datang Group, Electric Power Research Institute, and many leading enterprises to discuss the innovation and practice path of energy storage technology.

HongPower was invited to attend the meeting, and Dr. Liang JianGang, general manager of the company's R&D center, delivered a keynote speech and conducted in-depth exchanges on "Key Technologies and Applications of Grid-based Energy Storage".

Master Trends, Tackle New Power Challenges

With the continuous increase in the installed capacity of new energy, the safe and stable operation of the power grid is facing an unprecedented test. Especially in the context of a high proportion of new energy access, how to enhance the power grid support capacity and improve power quality has become the focus of the industry. At the same time, the power grids in some regions have put forward the specific application requirements of grid-based energy storage, and the energy storage industry is ushering in a new period of technological change.

In addition, the national standard for grid-based energy storage is in the project approval stage, which is expected to accelerate the process of industry standardization in the future and provide important guidance for technology promotion and project implementation.

In response to these industry trends, HongPower has always maintained forward-looking technological innovation, carried out in-depth research on the core issues of grid-based energy storage, and continuously optimized product solutions to help the construction of new power systems with higher performance and better adaptability energy storage technology.

Strengthen Core Tech, Drive Grid Storage Breakthroughs

In his speech, Dr. Liang Jiangang elaborated on the key technical indicators of grid-based energy storage. Through independent research and development, HongPower has built a number of core technology systems covering AC stability capability, providing stronger grid adaptability and more stable operation capability for energy storage systems.

1、Fast adjustment capability: Advanced primary frequency modulation technology is used to achieve millisecond-level response, effectively regulate the frequency fluctuation of the power grid, and improve the stability of the system.

2、Inertial support: Relying on the inertial response mechanism, the energy storage system can enhance the anti-disturbance ability of the power grid and alleviate voltage and frequency fluctuations when new energy is connected on a large scale.

3、Black start function: weak grid support capacity, no oscillation circulation. In the event of a sudden power outage, it provides security for the restart of the power grid. 

4、Multi-machine parallel optimization: Optimize the design of the number of parallel units to improve the scalability of the energy storage system and make it more suitable for large-scale new energy scenarios. 

5、Broadband vibration tuning suppression: an adaptive control strategy for strong and weak power grids, a hybrid application solution based on active damping and passive damping.

6、Powerful fault ride-through capability: Ensure that the energy storage system can still operate stably in the event of a short-term power grid failure, and avoid the energy storage equipment being disconnected due to voltage fluctuations. 

This seminar is not only an important platform for industry technical exchanges but also a key opportunity to promote the high-quality development of the energy storage industry. HongPower has always been committed to technological innovation, with forward-looking grid-based energy storage technology as the core, and deeply empowering the construction of new power systems.

In the future, the company will continue to deepen technology research and development, actively promote the standardization process of grid-based energy storage, and work together with upstream and downstream partners in the industrial chain to jointly promote the large-scale application of energy storage technology and help the energy industry move towards a more intelligent, efficient and green new era.
