And 202, performing load distribution and generating a load distribution signal based on the power supply state information of the high-voltage direct-current equipment and the battery and the energy demand information of the load equipment of the data center.
In this embodiment, load distribution may be performed according to the amount of power that can be provided by the high-voltage dc power supply and the battery and the amount of power required by the load device, for example, a portion of the amount of power required by the load device may be distributed and provided by the high-voltage dc power supply, and another portion of the amount of power required by the load device may be distributed and provided by the battery, so as to generate a load distribution signal. The load distribution signal is used for indicating the power supply amount of the high-voltage direct-current power supply and the power supply amount of the battery, namely the high-voltage direct-current power supply and the battery respectively provide corresponding electric quantity according to the indication of the load distribution signal.
The power supply state information of the high voltage direct current power supply and the battery may further include power supply costs of the high voltage direct current power supply and the battery, such as a unit electricity price of the high voltage direct current power supply and the battery.

Referring to fig. 3, a flow diagram of another embodiment of a method of power distribution in a data center according to the present disclosure is shown. As shown in fig. 3, a flow 300 of a power distribution method of a data center of the present embodiment includes the following steps:
In this embodiment, the power distribution system of the data center may include high voltage dc devices and batteries. The high-voltage direct-current equipment is connected with a mains supply, converts a mains supply into a high-voltage direct-current power supply and then transmits the high-voltage direct-current power supply to load equipment of the data center. The battery is also connected to load devices of the data center, and the battery may also provide power to the load devices.
The power supply state information of the high voltage dc device and the battery may include, but is not limited to, at least one of: the state information of normal or abnormal power supply, power supply efficiency, power supply time, power supply amount per unit time, power supply cost, residual electric quantity of the battery, charge-discharge state and switching time of the battery, and total use duration of the battery. The execution main body can monitor the states of the high-voltage direct-current device and the battery to acquire power supply state information. For example, parameters such as voltage, current, resistance of the battery, voltage, temperature and the like output by the high-voltage direct-current device can be detected through the monitoring circuit. The power supply state information can be obtained in various modes such as calculating the power supply efficiency of the high-voltage direct-current equipment and recording the charging and discharging time of the battery.
The energy demand information of the load equipment of the data center is the electricity consumption demand of the load equipment. And the calculation can be carried out according to the working power and the number of various types of load equipment.
And 302, in response to the fact that the high-voltage direct current equipment and the battery are available according to the power supply state information of the high-voltage direct current equipment and the battery, generating a load distribution signal according to a preset load distribution proportion and energy demand information of load equipment of the data center.
Wherein the load distribution signal is used for indicating the power supply amount of the high-voltage direct-current power supply and the power supply amount of the battery.
In this embodiment, whether the high voltage dc device and the battery can normally supply power may be determined according to the power supply state information of the high voltage dc device and the battery. Specifically, whether the power supply state parameters such as the temperature, the voltage and the internal resistance of the battery are within the preset value range under the normal discharge condition can be judged according to the power supply state parameters such as the power supply voltage, the power supply current and the power supply efficiency of the high-voltage direct-current equipment. If the power supply state parameter of the high-voltage direct-current equipment is in the numerical range under the preset normal power supply condition, the high-voltage direct-current equipment can be determined to be available; if the power supply state parameter of the battery is within the value range under the preset normal discharge condition, the battery can be determined to be available.
The specific weight of the load distribution of the high voltage dc power supply and the battery may be set in advance, for example, 80% and 20% for the high voltage dc device and the battery, respectively. Optionally, load distribution specific gravities of the high-voltage direct-current power supply and the battery in different time periods can be set, and particularly, different load distribution specific gravities can be set according to peak-valley time-of-use prices. Particularly, in the peak time period of electricity price, the electric energy stored by the battery can be fully utilized to provide a power supply required by load operation; during the time period of low price of electricity, the high-voltage direct-current equipment can be utilized to provide power as much as possible. The load distribution specific gravity of the battery during the peak electricity price period may be set higher than that during the valley electricity price period, for example, 80% or 100% may be set for the peak electricity price period and 20% or 0 may be set for the valley electricity price period.
The execution main body of the power distribution method of the data center can calculate the electric quantity which needs to be provided by the high-voltage direct-current equipment and the battery respectively according to the preset load distribution proportion and the energy demand information of the load equipment of the data center, and generate load distribution signals which indicate the high-voltage direct-current equipment and the battery to provide corresponding electric quantity respectively.
Therefore, when both the high-voltage direct-current equipment and the battery are available, the load distribution signal is generated according to the preset load distribution proportion, the discharge performance of the battery can be fully utilized to share the load of the high-voltage direct-current equipment, and the stable operation of a power supply system is ensured.
In this embodiment, the battery is a rechargeable battery. The preset charging condition may be a condition that a preset power supply state that the battery needs to be charged satisfies. When the electric quantity of the battery reaches the lowest early warning value or the voltage of the battery end is lower than the preset voltage value, the battery can be stopped from being used for supplying power to the load equipment. At this point, the high voltage dc power supply is required to power all of the load devices, and a load distribution signal may be generated that indicates that the energy demand of the load devices is being met by the high voltage dc power supply.
At this time, the power distribution method of the data center may further include: and generating a battery charging signal and transmitting the battery charging signal to the high-voltage direct-current device in response to the fact that the power supply state information of the battery meets the preset charging condition, so as to control the high-voltage direct-current device to charge the battery.
The battery can be connected with high-voltage direct-current equipment, and the high-voltage direct-current equipment can charge the battery after converting commercial power into a direct-current power supply under the control of a battery charging signal. When the power supply state information of the battery meets the preset charging condition, the load equipment can be supplied with power and the battery can be charged through the high-voltage direct-current equipment.
Optionally, the power supply status information of the battery includes a current working time, and the preset charging condition includes that the current working time is within a preset power consumption valley time period. The peak-valley electricity rate is generally an electricity rate divided according to the peak and valley of the used amount of electricity in order to improve the efficiency of the use of electric energy and reduce the load of the electricity generation, and the period of the valley of the used amount of electricity, i.e. the period of the low valley of the electricity rate, is, for example, 23: 00 to 7 am earlier. Therefore, the high-voltage direct-current equipment is controlled to charge the battery and provide power required by all load equipment in the electricity price off-peak time period, and the battery can be charged in the electricity consumption off-peak time period to realize low-cost and high-efficiency energy storage, so that the energy stored by the battery is utilized to supply power to the load in the electricity consumption peak time period.
By combining step 302 and step 303, the charge and discharge performance of the battery can be effectively utilized, and the battery can be recycled.
In response to determining a fault in the high voltage dc device from the power supply status information of the high voltage dc device, a load distribution signal is generated indicating that the energy demand of the load device is met by the battery supply, step 304.
In this embodiment, whether the high-voltage direct-current device fails or not may be monitored based on the power supply state information, for example, the voltage and the current output by the high-voltage direct-current device are monitored, and whether the voltage and the current are within a normal range or not is determined. If the high-voltage direct current equipment is monitored to have a fault, the battery can be controlled to provide electric quantity meeting the energy requirements of all load equipment so as to ensure the normal operation of the load equipment.
Optionally, if a fault of the high-voltage direct-current equipment is monitored, the time length during which the electric quantity of the battery can maintain the normal operation of the data center can be estimated, and prompt information is generated to prompt that the high-voltage direct-current equipment needs to be repaired within the time length.
And 305, generating a load distribution signal indicating that the energy requirement of the load equipment is met by the high-voltage direct-current equipment in response to the fact that the power supply state of the battery is switched within the preset time period according to the power supply state information of the battery.
The power supply state information of the battery may further include time information of switching of the power supply state of the battery, and the power supply state of the battery may include: the charging state comprises a floating charging state and a uniform charging state. If the power supply state of the battery is monitored to be switched over in a preset time period, for example, the battery is monitored to be switched from a floating charge state to a static state in the preset time period, or the battery is switched from a discharge state to a fault state in the preset time period, a load distribution signal for controlling the high-voltage direct-current equipment to provide electric quantity meeting the energy demand of all load equipment can be generated. The preset time period may be a short time period before the current time, for example, within 10 seconds before the current time.
Therefore, the high-voltage direct-current equipment is controlled to supply power within a period of time after the power supply state of the battery is switched, the battery does not supply power, and the loss of the battery caused by frequent switching within a short time of the battery state can be avoided. And the fault state of the battery can be detected in time, so that the abnormity of the battery can be judged.
And step 306, respectively sending load distribution signals to the high-voltage direct current equipment and the battery to control the high-voltage direct current equipment and the battery to respectively provide power for the load equipment of the data center according to the load distribution signals.
The load sharing signal may be sent to the high voltage dc device and the battery, respectively. And after receiving the load distribution signal, the high-voltage direct current equipment and the battery respectively provide power for the load equipment according to the indication of the load distribution signal.
According to the power supply method of the data center, the process 300 determines the power supply quantity distribution strategy of the high-voltage direct current equipment and the battery according to the power supply state information of the high-voltage direct current equipment and the battery, so that reasonable distribution of electric energy is realized, and the use efficiency of the electric energy can be improved.
