GRID-SIDE ENERGY STORAGE PROJECTS

We'll organize a multi-storage block.
Portable, protected and accepted grid assets

From system design, equipment integration, debugging and networking to continuous operation, large-scale EnergyStorage Systems, with a real grid-friendly capability, is created by independent Block, unified dispatch, rapid protection and verifiable engineering evidence.

DEMO PROJECT

4 x 5.064 MWh DC Block | 4 x 1.25 MW PCS (example)

01 Total site plane and system composition

  • Four stand-alone DC Blocks, stand-alone partitions, fire spacing and access.
  • Each Block Capacity 5.064MWh, single Block can be isolated.
  • Every Block Counterpart 1 1.25 MW PCS35 kV system.
  • Main change/ switchboard / PCCs constitute a unified net border.
  • Station control configuration EMS, metrology, protection, communication and event recording.
  • Fire, heat management and Block are separated into layers of security structures.

03 · Dispatch and protection: two parallel lifelines

The dispatch chain determines "how to run" and the protection chain determines "how to determine, quickly and independently stop a dangerous state in the event of an anomaly".
