In today's rapidly evolving energy technology landscape, Beijing Honghui International Energy Technology Development Co., Ltd. ( abbreviated as 'Honghui Energy' ) Together with Datang East China Electric Power Research Institute, we witnessed another milestone in the field of new energy milestone event — actively supporting grid-forming microgrid successfully completed 72 hours trial operation!

At 12:18 on March 11, 2025, Datang East China Electric Power Research Institute announced that its active support grid-forming microgrid project has successfully completed a 72-hour trial operation. . The project was led by Datang East China Electric Power Research Institute, with Honghui Energy serving as a key technical partner, providing crucial technical support. The successful completion of this trial operation marks a significant advancement in China's new power system sector.

This microgrid integrates Flywheel energy storage, lithium iron phosphate battery energy storage, perovskite photovoltaic modules, crystalline silicon photovoltaic modules, vertical axis wind turbines, horizontal axis wind turbines, charging piles, and mobile variable load carts It integrates diverse elements such as 'source-grid-load-storage-charge', demonstrating Honghui Energy's deep expertise in energy storage, conversion, and intelligent management.

During the 72-hour trial operation period, the project team successfully completed multiple key verifications, including cycle charging and discharging tests of flywheel energy storage and lithium iron phosphate battery energy storage, microgrid grid-connected and off-grid mode switching tests, as well as active grid-forming support of flywheel energy storage in off-grid mode, and mutual charging and discharging tests between lithium iron phosphate battery energy storage and flywheel energy storage. Test results show that All technical indicators have met or exceeded the design requirements, with the system operating stably and reliably, fully demonstrating the excellent performance of Honghui Energy's flywheel energy storage in active grid-forming support.

Project significance:

1. demonstration base : This microgrid not only provides Datang East China Electric Power Research Institute with an empirical base for technological research and talent cultivation in the field of new power systems, but also offers valuable measured data for the subsequent development and optimization of Honghui Energy's products.

2. power supply reliability This project effectively ensures the power supply reliability for important instruments and equipment in the company's campus during planned or unplanned power outages, thereby enhancing the energy security level of the campus.

3. future outlook Building on this success, Honghui Energy will further deepen cooperation with Datang East China Electric Power Research Institute to explore the adaptability research of active support grid-forming microgrids in fields such as hydrogen-ammonia-alcohol and air separation, as well as the application of flywheel energy storage and electrochemical energy storage in the flexible adjustment of thermal power and gas turbines, and smart energy systems in remote areas like islands, contributing to the green and low-carbon transformation of energy and the construction of a new power system.

The successful completion of this active support grid-forming microgrid trial operation marks a significant breakthrough for Honghui Energy in the new energy field. Moving forward, Honghui Energy will continue to uphold the principles of innovation, collaboration, and mutual benefit, collaborating with more partners to jointly advance the innovation and development of energy technology, contributing to the construction of a clean, low-carbon, safe, and efficient energy system!
