Referring to fig. 4, a flowchart of a power supply control method according to an embodiment of the present application is shown in fig. 4, and the method may include the following steps 410 to 440.
Step 410: and collecting the power supply load rate of the uninterrupted power supply in each power supply combination in real time.
The energy storage system is applied to the data center system and is mainly executed by an energy management system of the energy storage system. The data center system comprises a plurality of power supply combinations, a direct current bus system and an energy storage system, wherein each power supply combination comprises load equipment, an uninterruptible power supply and a DC/DC converter which are sequentially connected, the energy storage system comprises a plurality of battery systems which are distributed, and the battery systems are connected to the power supply combinations after being converged through the direct current bus system. The architecture of the data center system is described in detail in connection with the foregoing.
Here, the power supply load ratio is a ratio between an actual output power and a rated power of the uninterruptible power supply.
In the running process of the data center system, the power consumption of each power supply combination can change along with time due to business volume variation, air temperature variation and the like. At this time, the power load rate of the uninterruptible power supply in the power supply combination may change. The energy management system can collect the power supply load rates of the uninterrupted power supplies in all power supply combinations in real time so as to monitor the power supply load rates of all the power supply combinations.
Step 420: and judging whether the power supply load rate exceeds a preset first load rate threshold value.
The first load rate threshold is a load rate threshold which needs to consider the risk of over-electricity (load power consumption exceeds the upper power consumption limit), and can be configured according to the requirement. Illustratively, the first load factor threshold may be 90%.
For each power supply combination, after obtaining a power supply load rate of the uninterruptible power supply of the power supply combination, it may be determined whether the power supply load rate exceeds a first load rate threshold. In one case, if not exceeded, the power load rate of the uninterruptible power supply of the power supply combination may continue to be monitored. In another case, if so, step 430 may be performed.
Step 430: and if so, determining the power supply combination with the power supply load rate exceeding the first load rate threshold as a target power supply combination.
Step 440: and controlling the energy storage system to supply power for the load equipment of the target power supply combination through the DC/DC converter of the target power supply combination.
In the event that the power supply load rate of the uninterruptible power supply within any one of the power supply combinations exceeds a first load rate threshold, the power supply combination may be determined to be the target power supply combination. At this time, the energy management system may notify the DC/DC converter of the target power supply combination, and control the energy storage system to supply power to the load device of the target power supply combination. The energy management system may issue a command to cause the DC/DC converter to switch to an anti-peak mode, output at constant power, the output voltage may be adaptive to a DC bus voltage of the uninterruptible power supply, and the output power may be determined based on the first load factor threshold.
At the moment, the energy storage system and the uninterruptible power supply in the target power supply combination jointly supply power for the load equipment in the target power supply combination, so that the overpower risk of the uninterruptible power supply in the target power supply combination is reduced.
Through the measures, under the condition that the power supply load rate in any power supply combination is too high, the energy storage system can be used for reducing the load of the uninterrupted power supply in the power supply combination, the problem that a server is down due to super-conduction is solved, and the safe and stable operation of the business of the data center is ensured. In addition, the energy storage system is connected to the power distribution framework of the data center in a distributed deployment and centralized access mode, and the flexible deployment of the energy storage system is realized through the decoupling of the battery and the DC/DC converter, so that the problem of failure of the energy storage system caused by single battery faults is avoided, and the availability of the energy storage system is improved. Because the plurality of battery systems in the energy storage system are connected into the direct current bus system in parallel, the total power supply amount of the energy storage system is very high, and under the condition that the power supply load rate in any power supply combination is too high, the load of the uninterrupted power supply can be fully reduced by means of the energy storage system, and the time requirement for the subsequent equipment migration is reduced.
In an embodiment, after controlling the energy storage system to supply power to the load device of the target power supply combination, the energy management system may issue an overpower risk prompt to the load device of the target power supply combination. The energy management system can send out a power failure risk prompt to the IT equipment of the target power supply combination. The power supply system comprises a target power supply combination, a power supply system and a power supply system, wherein the power supply system is used for supplying power to the power supply system, and the power supply system is used for supplying power to the power supply system. The migration process may be to transfer a portion of the servers of the target power supply combination to the racks of other power supply combinations that are not powered up. Thereby reducing the power consumption of the target power supply combination to reduce the power supply load rate of the target power supply combination. Specifically, IT equipment in the target power supply combination can be transferred to a cabinet of the power supply combination with lower power supply load rate, so that the situation that the power supply load rate of other power supply combinations is too high after the equipment is transferred is avoided.
By the measures, for the target power supply combination with high power supply load rate, the power failure risk prompt can be issued to instruct the load equipment in the target power supply combination to carry out migration processing, so that the power supply load rates of all the power supply combinations of the data center are more balanced. Because the energy storage system comprises a plurality of battery systems which are distributed and arranged, and the energy storage system has enough electric quantity, the IT equipment of the target power supply combination has enough time to carry out migration treatment, and the over-electricity risk caused by the power failure of the energy storage system in the migration process is avoided.
In an embodiment, after the energy management system issues the power failure risk prompt to the load device of the target power supply combination, in a migration process of the load device of the target power supply combination, a power supply load rate of the uninterruptible power supply in the target power supply combination can be obtained in real time, and whether the power supply load rate is greater than a preset second load rate threshold value is judged. The second load rate threshold is smaller than the first load rate threshold, and the second load rate threshold is used for distinguishing power supply combinations separated from the over-electricity risk. Illustratively, the second load factor threshold may be 70%.
Under the condition, if the power supply load rate is larger than the preset second load rate threshold value, it is indicated that the power supply load rate of the uninterruptible power supply of the target power supply combination is still higher, and there is an overpower risk, at this time, the energy management system can control the energy storage system to continue to supply power for the load equipment of the target power supply combination through the DC/DC converter of the target power supply combination.
In this case, since the IT devices within the target power supply combination are still migrated to other power supply combinations, the power supply load rate may be continuously obtained and compared to the second load rate threshold.
In another case, if not (i.e. the power load rate is less than or equal to the preset second load rate threshold), it is indicated that the power load rate of the uninterruptible power supply of the target power supply combination is reduced, and the risk of overpotential is eliminated, at this time, the energy management system may control the DC/DC converter to exit the anti-peak mode, and stop the energy storage system from supplying power to the load device of the target power supply combination through the DC/DC converter of the target power supply combination.
Referring to fig. 5, an overall flow chart of a power supply control method according to an embodiment of the present application is shown in fig. 5, where an energy management system may detect a power load rate of each power supply combination and determine whether the power load rate of each power supply combination is greater than a first load rate threshold (90%). In one case, if not, the DC/DC converter in the power supply combination can be controlled to exit the anti-peak mode, and the power supply load rate of the power supply combination can be continuously detected. In another case, if yes, the DC/DC converter in the power supply combination can be controlled to switch to the anti-peak mode, and the energy storage system is controlled by the DC/DC converter to supply power to the load equipment in the power supply combination. In addition, IT devices within the power supply combination may be controlled to migrate to other power supply combinations.
And in the migration process, continuously detecting the power supply load rate of the power supply combination, and judging whether the power supply load rate is larger than a second load rate threshold (70%). And under the condition that the power supply load rate is larger than the second load rate threshold value, continuously controlling the DC/DC converter to operate in the anti-peak mode, and continuously migrating the load equipment. In the case where the power supply load ratio is not greater than the second load ratio, the DC/DC converter of the power supply combination may be controlled to exit the anti-peak mode.
In an embodiment, the energy management system may control the energy storage system to supply power to the load device of the power supply combination through the DC/DC converter of the power supply combination in the case that the uninterruptible power supply is powered off in any power supply combination.
Under the condition, emergency power supply for the load equipment in the power supply combination is realized, and downtime of the load equipment caused by sudden power failure is avoided.
In an embodiment, in the event that the energy storage system ceases to supply power, the energy management system may check whether the power of the energy storage system is below a power target. Here, the electric quantity target may be configured as needed. For example, the charge target may be up to 100% of the charge of the battery system in the energy storage system, or up to 90% of the charge.
In one aspect, if the power of the energy storage system reaches the power target, no processing may be performed. On the other hand, if the electric quantity of the energy storage system is lower than the electric quantity target, the uninterruptible power supply can be controlled by the DC/DC converter for indicating a power supply combination to charge the energy storage system until the electric quantity target is reached.
Through the measures, under the condition that the electric quantity of the energy storage system is lower than an electric quantity target, the battery in the energy storage system can be charged in time, so that the energy storage system is used for avoiding the over-electricity risk in the follow-up process.
In an embodiment, when the uninterruptible power supply is controlled to charge the energy storage system, the energy management system may generate a charging policy according to the electricity price time-sharing condition. Wherein the charging strategy characterizes a charging priority over a peak electrical time period for the valley electrical time period.
