Uzbekistanproject (CRRC-Project)

Background

  • The Obi 100MW/200MWh energy storage power station is located in Chirchiq Town, Namangan Province, Uzbekistan.

On-site situation:

  • The site has harsh climate with frequent heavy rain, dust and sandstorms. The power grid is weak and unstable. So the energy storage system needs grid- connected and off-grid switching funtions._x0002_

Main challenge:

  • The ESS must withstand abnormal system frequency, and have grid support, low and high voltage ride – through functions.

Solution

  • A unified control strategy of VSG and vector control effectively solve the problem. Joint commissioning with the local power grid.

Australianproject (CRRC-Project)

Background:

  • The 10MWh energy starage power station is located in Perth
    West Australia.

On-site Situation:

  • The local temperature is over 50, sunburn is strong; Off-grid,
    truck charging scenario.

Main Challenge:

  • Pure off-grid project need more stable AC/DC reponse
    capability. Customer has no related experience before, needs
    rapid reponse and strong local support.

Solution:

  • Supply DC energy storage container, provide strong local
    support team, effectively lead local integration team finish the
    job and successfully accomplish the task beyond customer
    expectation.
