NR’s BESS control supports various operating modes to meet the requirements of different energy storage application scenarios for peak shaving, frequency & voltage regulation, spinning reserve, load shifting, and fluctuation smoothing, etc.

  • PQ decoupling mode: Decoupled control of active and reactive power under grid-connection condition is suitable for peak shaving and frequency & voltage regulation.
  • VF control mode: Frequency & voltage control is suitable for the reliable operation islanded mode.
  • Droop control mode: Active power-frequency and reactive power-voltage droop control is suitable for frequency & voltage regulation
  • VSG Mode: Simulating the external characteristics of synchronous generator that it is suitable for the seamless switchover between grid-connected mode and islanded mode.
  • Black start mode: To establish and stabilize the grid voltage and frequency. It is suitable for the black-start application under the islanded condition or spinning reserve application
