Data center power challenges, storage technology becomes a breakthrough
In recent years, with the explosive growth of data business demands such as mobile Internet, Internet of Things,
and cloud computing and the rapid development of IT technology, data centers have evolved into a rapidly developing
industry and become an important part of the new generation of information industry. Relevant research institutions
predict that the market size of my country”s data centers will exceed 180 billion yuan in 2019, of which about 70% will be newly built data centers.
Data center power challenges
At the same time, data centers are facing a series of problems such as excessive energy consumption, load surge,
and main equipment failure, and these problems are becoming more and more severe. According to data from the China
Data Center Energy Conservation Technical Committee, the total power consumption of China”s data centers in 2017 reached
120-130 billion kilowatt hours, exceeding the power generation of the Three Gorges Dam in 2017 (97.605 billion kilowatt hours) and
the Gezhouba Power Plant (190.5 billion kilowatt-hours).
Ensuring safe and reliable power and network supply are the two most basic functions of a data center, so data centers are equipped
with uninterruptible power supplies (UPS). The traditional data center power backup mode is: when the mains power supply is normal,
the UPS supplies power to the load after “filtering impurities from the mains power” and charges the battery at the same time; when the
mains power is abnormal (power supply is interrupted), the battery discharge is supplied through the UPS The load ensures power supply.
However, as the scale and density of data centers increases, this model will inevitably face some outstanding problems:
First, electricity bills are high. The operating costs after the data center is built mainly come from electricity charges. Statistics show that electricity
expenses account for more than 60% of the data center operating expenses. Second, battery investment is high. Data centers mostly use lead-acid batteries
for backup power. The life of these batteries is usually about 5 years. To ensure the safety of backup power, they must be replaced regularly.
Moreover, most batteries do not discharge during their service life, resulting in a waste of resources (sunk cost). Third, the battery has been in a float charge state
for a long time and its health status is unknown. Some data centers even need to verify battery performance through regular false load tests, and the cost of this test is also considerable.
Energy storage technology becomes a new breakthrough
In recent years, data center energy storage technology has developed rapidly. With its characteristics and advantages such as peak shaving, on-demand response,
on-demand management, power supply quality assurance, renewable energy integration, and backup energy storage, it has become an important means to solve the above problems. .
Data center energy storage places higher demands on batteries. Traditional lead-acid batteries are considered to be the “weak link” of data center power equipment
due to their high maintenance costs, heavy weight, need for regular replacement, and potential failures. In contrast, lithium-ion batteries have longer cycle life, longer run
times, and the ability to operate at higher ambient temperatures, and have higher power density, occupying the same space as lead for the same capacity. One-third of the
capacity of acid batteries can save more space in the machine room, and lithium-ion batteries also have instantaneous response capabilities.
Supercapacitors combined with traditional UPS configurations can also help solve the problem . Not only can they respond instantly to power outages or power quality issues
without the initial voltage drop caused by battery resistance issues, they can also enable data centers to use batteries more frequently for peak shaving, thereby reducing monthly
power demand costs. They also Helps extend the life of lead-acid batteries. The advantages of supercapacitors are their high availability, relatively low maintenance, and long service life.
Advantages of new energy storage architecture
In addition to the equipment itself, the core of the energy storage system is system management. The generally designed working mode of the energy storage system is: operating
in island mode to provide emergency power supply in the event of generator failure; energy distribution is performed according to the quota of the power grid to solve the problem
of power supply security. However, real-time switching of the output current source and voltage source cannot be realized, and uninterrupted power supply to the load cannot be guaranteed. The new energy storage
architecture represented by Eaton energy storage system, through optimized system design, parallel power supply in mains mode and energy storage system, can effectively
solve the possible power outage caused by abnormal switching of the power grid, and also solve the problem of energy storage system Energy distribution management issues
; combined with optimized battery management technology, it can achieve maximum economic benefits for customers.
