Automatic State of Charge management in a multi-MW Battery plant


Auto charge or discharge service

  • Capability to export power at a specific level for a specific period or until the exported energy reaches a limit.
  • Limited by Time (“run for 0.5 hours) or Energy (“run till charging used x MWh)

SOC Setpoint

  • Achieve a specific setpoint
  • Achieve a specific setpoint at a specific hour

Charge/discharge through a setpoint

Storage Control loops

Feed forward control loop

  • To compensate for standard losses

Availability based

  • To compensate for unavailable inverters
    Closed loop control schemes

Two separate PID loops, one for Active Power (P) and one for Reactive Power (Q)

  • Less than 1 second loop

Control Scheduler

Enable maximum automation on service/revenue stacking scenario
Maximum automated balance of market services in a scheduled and coordinated manner
Specific control actions may be scheduled

  • Active power control
  • Battery storage FFR participation

Scheduling is performed with repetitions
