Step 301 , obtain the power supply status information of the high-voltage direct current equipment and the battery in the power distribution system, and the energy demand information of the load equipment of the data center.

In this embodiment, the power distribution system of the data center may include high-voltage direct current equipment and batteries. Among them, the high-voltage DC equipment is connected to the mains, and the mains power is converted into high-voltage DC power and then transmitted to the load equipment in the data center. The battery is also connected to the load equipment in the data center, and the battery can also provide power to the load equipment.

For example, parameters such as voltage, current, battery resistance, voltage, temperature, etc. output by the high-voltage DC device can be detected through the monitoring circuit. The power supply status information can also be obtained by calculating the power supply efficiency of the high-voltage DC device and recording the charging and discharging time of the battery.

The energy demand information of the load equipment in the data center is the power consumption demand of the load equipment. It can be calculated according to the working power and quantity of various types of load equipment.

Step 302 , in response to determining that both the HVDC device and the battery are available according to the power supply status information of the HVDC device and the battery, generate a load distribution signal according to a preset load distribution ratio and energy demand information of the load device in the data center.

Among them, the load distribution signal is used to indicate the power supply of the high-voltage DC power supply and the power supply of the battery.

In this embodiment, whether the high-voltage direct-current device and the battery can supply power normally can be determined according to the power supply status information of the high-voltage direct-current device and the battery. Specifically, it can be judged according to the power supply status parameters such as the power supply voltage, power supply current, and power supply efficiency of the high-voltage DC device whether it is within the preset value range under normal power supply conditions, and the power supply status of the battery such as temperature, voltage, and internal resistance can be judged. Whether the parameter is within the preset value range under normal discharge conditions. If the power supply state parameters of the high-voltage DC equipment are within the above preset value range under normal power supply conditions, it can be determined that the high-voltage DC equipment is available; Make sure the battery is available.

The load distribution proportions of the high-voltage direct current power supply and the battery can be preset, for example, the load distribution proportions of the high-voltage direct current equipment and the battery are set to be 80% and 20% respectively. Optionally, the load distribution ratio of the high-voltage DC power supply and the battery in different time periods can also be set, and specifically, different load distribution ratios can be set according to the peak-valley time-of-use electricity price. Specifically, during the peak period of electricity price, the electric energy stored in the battery can be fully utilized to provide the power required for the load work; and during the period of low electricity price, high-voltage direct current equipment can be used as much as possible to provide the power source. Then you can set the load distribution ratio of the battery during the peak electricity price period to be higher than the load distribution ratio during the electricity price trough time period. The segment battery has a load sharing ratio of 20% or 0.

The execution body of the power distribution method of the data center can calculate the power required to be provided by the high-voltage direct current equipment and the battery according to the above-mentioned preset load distribution ratio and the energy demand information of the load equipment of the data center, and generate instructions indicating the high-voltage direct current equipment and the battery. The batteries respectively provide load sharing signals of corresponding power.

In this way, when both the HVDC equipment and the battery are available, the load distribution signal is generated according to the preset load distribution ratio, which can make full use of the discharge performance of the battery to share the load of the HVDC equipment and ensure the stable operation of the power supply system.

Step 303 , in response to determining that the power supply state information of the battery satisfies the preset charging condition, a load distribution signal indicating that the energy demand of the load device is met by the HVDC device is generated.

In this embodiment, the battery is a rechargeable battery. The above-mentioned preset charging condition may be a preset condition that is satisfied by the power supply state of the battery that needs to be charged. When the power of the battery reaches the minimum warning value or the voltage at the battery terminal is lower than the preset voltage value, the battery can be stopped to provide power to the load device. At this time, a high-voltage DC power supply is required to provide power for all the load devices, and a load distribution signal can be generated to indicate that the high-voltage DC device is provided to meet the energy demand of the load devices.

At this time, the power distribution method of the data center may further include: in response to determining that the power supply status information of the battery meets a preset charging condition, generating a battery charging signal and sending it to the HVDC device to control the HVDC device to charge the battery.

The above-mentioned battery can be connected with a high-voltage DC device, and the high-voltage DC device can charge the battery after converting the commercial power into a DC power source under the control of the battery charging signal.

Optionally, the power supply status information of the battery includes the current working time, and the preset charging condition includes that the current working time is within a preset low power consumption time period. Usually, the peak-valley electricity price is to improve the efficiency of electricity utilization and reduce the power generation load. In this way, during the low electricity price period, the high-voltage DC equipment is controlled to charge the battery and provide the power required by all load equipment, and the battery can be charged during the low power consumption period to realize low-cost and high-efficiency energy storage, so that the power consumption can be The energy stored in the battery is used to supply power to the load during peak hours.

By combining step 302 and step 303, the charge and discharge performance of the battery can be effectively utilized, and the recycling of the battery can be realized.

Step 304 , in response to determining that the HVDC device is faulty according to the power supply status information of the HVDC device, generate a load distribution signal indicating that the energy demand of the load device is met by the battery being provided.

In this embodiment, whether the HVDC device is faulty can be monitored based on the power supply status information, for example, the voltage and current output by the HVDC device can be monitored to determine whether it is within a normal range. If it is detected that the high-voltage direct current equipment fails, the battery can be controlled to provide power that meets the energy requirements of all load equipment, so as to ensure the normal operation of the load equipment.

Optionally, if the failure of the high-voltage direct current equipment is detected, the period for which the battery power can maintain the normal operation of the data center can also be estimated, and prompt information is generated to prompt that the high-voltage direct current equipment needs to be repaired within the period of time.

Step 305 , in response to determining that the power supply state of the battery is switched within a preset time period according to the power supply state information of the battery, generate a load distribution signal indicating that the energy demand of the load device is met by the HVDC device.

The power supply state information of the battery may also include time information of the power supply state switching of the battery. The power supply state of the battery may include: charging state, discharging state, resting state, and fault state, wherein the charging state includes floating charging state and equalizing charging state. If it is monitored that the power supply state of the battery has been switched within a preset period of time, for example, it is monitored that the battery is switched from a floating state to a resting state within a preset period of time, or the battery is switched from a discharge state to a fault within a preset period of time. state, a load distribution signal can be generated that controls the HVDC device to provide the amount of electricity that meets the energy requirements of all load devices. The preset time period may be a short period of time before the current moment, for example, within 10 seconds before the current moment.

In this way, by controlling the power supply by the high-voltage DC device 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 due to frequent switching of the battery state in a short period of time can be avoided. It can also detect the fault state of the battery in time, and realize the judgment of the abnormality of the battery.

Step 306: Send a load distribution signal to the HVDC device and the battery respectively, so as to control the HVDC device and the battery to respectively provide power to the load device in the data center according to the load distribution signal.

The load sharing signal can be sent separately to the HVDC device and the battery. After receiving the load distribution signal, the HVDC device and the battery provide power to the load device respectively according to the instructions of the load distribution signal.

In the process 300 of the power supply method for the data center, the power supply distribution strategy of the HVDC device and the battery is determined according to the power supply status information of the HVDC device and the battery, so as to realize the reasonable distribution of electric energy and improve the utilization efficiency of electric energy.
