Grid-Forming BESS Platform
Modular multi-level cascade storage in three standard configurations: 365 kWh low-voltage cabinet, 5 MWh low-voltage container and 50 MWh medium-voltage container connecting directly at 33–35 kV. Full liquid cooling, LFP cells, grid-forming control, sub-5 ms response and 3 pu overload for 10 seconds at MV.
- Grid-forming control supporting black start and island operation
- Modular multi-level cascade topology with direct 33 – 35 kV connection and no station transformer
- Full liquid (water) cooling with LFP 3.2 V / 314 Ah cells
- Response time < 5 ms on the medium-voltage platform, < 20 ms on low-voltage
- Overload to 3 pu for 10 seconds on the medium-voltage platform
- Supplementary batteries operate as part of the existing system with no additional controller
Overview
A grid-forming battery energy storage platform that provides a voltage and frequency reference rather than consuming one. It supports black start, island operation and reconnection of distributed generation after a network fault.
The architecture is a modular multi-level cascade. At medium voltage it connects directly to a 33 – 35 kV bus with no station transformer in the path. Every sub-module added is another element of redundancy, and supplementary batteries operate as part of the existing system without an additional controller or EMS modification.
Standard configurations run from a 365 kWh low-voltage cabinet to a 50 MWh medium-voltage block. Figures are indicative standard-product values; project ratings, cell selection and enclosure specification are confirmed per application.
