Uzbekistanproject (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.

Project Overview

• Background: The end – user has commissioned the energycompanytoprocure energy storage systemequipment. Theprojectislocated in Abuja, the capital ofNigeria.
• Application: PV+ESS
• Capacity：14MW/40MWh

Main challenge & Solution

• Offer a 10 – year warranty. Consider after – salesserviceresponse speed and cost. Hire and trainlocaltechniciansto provide after – sales service. Key technology innovation
• Fire protection meets IEC standard, andalsointegratesNFPA 68 and NFPA69.
• Explosion vent panels are installed onthetopof container.The ventilation systemhas obtainedanexplosion protection simulation report inaccordancewithNFPA 69.
• The overall fire protection design complieswithNFPA855.

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.
