Recently, an industry landmark high-voltage cascaded energy storage project—the Mingyang Weijun 400MW/2400MWh high-voltage cascaded BESS successfully achieved full-capacity grid connection.
As the core Battery Management System (BMS) supplier for the project, Gold Electronic provided a full-stack BESS (total scale of 400MW/2400MWh) solution. With reliable intelligent control capabilities, it facilitated the stable commissioning of this large-scale high-voltage direct-connect energy storage project.
Located in Tumd Right Banner, Baotou, Inner Mongolia, within the Weijun 500kV collector station area of the Western Inner Mongolia Grid, the project is a crucial component of the regional large-scale independent energy storage cluster. The project adopts a 35kV high-voltage cascaded direct-connect technology route, relying on an H-bridge cascaded topology to eliminate the need for step-up transformers. This effectively improves the comprehensive operational efficiency of the system and has significant demonstration value for cost reduction and efficiency enhancement in energy storage power stations.
Compared with conventional systems, high-voltage direct-connect BESS imposes higher requirements on battery status monitoring, balancing control, safety early warning, and cluster collaborative management.
Gold Electronic's full-stack BMS technology ecosystem solution is deeply optimized for large-capacity high-voltage cascaded scenarios. It achieves large-scale real-time cell monitoring, precise balancing, and multi-level safety protection, ensuring the long-term stable operation of large-capacity energy storage containers and adapting to the long-cycle, high-frequency charge/discharge conditions of independent energy storage power stations.
The successful grid connection of this 400MW/2400MWh project further verifies the engineering implementation capabilities of Gold Electronic's BMS technology in the large-capacity high-voltage cascaded energy storage sector. In the future, Gold Electronic will continue to iterate its full-stack BMS technology ecosystem solution to empower more large-scale energy storage projects and contribute to the construction of novel power systems.
