Distributed Energy Storage System Solution for Outdoor Cabinets

Industrial and commercial parks, PV & storage charging station, microgrid side

Overview

The lithium iron phosphate battery, battery management system, energy storage converter, monitoring module, power distribution module, fire protection and temperature control module are highly integrated into a standardized outdoor cabinet, which has the advantages of high integration and low floor area, and can realize the functions of peak-load shifting, demand management, demand-side response, PV-storage-charging linkage, etc. 

Features

01

Discharge capacity: regularly conduct SOC automatic calibration; One cluster and one management, avoid parallel mismatch, and increase the discharge capacity in the whole life cycle by about 10%

02

Intelligent temperature control: With intelligent temperature control function, the internal temperature rise is less than 5℃, 0.5C, and the service life of the battery is increased by 10% based on the container scheme

03

Equipment investment: the cost is reduced by up to 35%

04

Floor area: Compact layout, higher degree of integration, saving about 50% ~ 80% of the floor area

05

Modular system design: PCS is of modular design, and the failure of a single PCS or a single battery cluster does not affect the availability of other battery clusters, and the system availability can reach 99%

06

Safety performance: change the large-scale centralized mode to outdoor cabinet, which reduces the fault loss caused by fire safety by more than 90% and avoids the risk of fire spread

07

Convenience: with prefabricated installation, the wiring and commissioning of on-site installation is avoided; change power plant construction into plant installation, which reduces the design cost by 50% and installation and commissioning cost by 60%

08

System efficiency: No isolation transformer, improve the daily combined efficiency by 2%; Three-level high-performance energy storage converter improves daily combined efficiency by 0.9%; Distributed air conditioning layout, the temperature difference is reduced by 2~5℃, the consistency is improved by 10%, the daily combined efficiency is improved by 1.14%, and the daily combined efficiency is improved by about 4.04%
