The load system 900 may be, without limitation, an ac load system or a dc load system or both. As shown in fig. 1, the intelligent electricity-saving management and control system 100 mainly includes a central computing management and control system 10, an electric power supply system 20, and an electric power supply monitoring and adjusting system 30. The power supply system 20 and the power supply monitoring and adjusting system 30 are electrically connected to the central computing and controlling system 10, respectively, and the power supply system 20 is connected to a load system 900 through the power supply monitoring and adjusting system 30.

The output unit 103 may be configured to: the related data and settings are transmitted to a specific location in a wired or wireless manner, and the specific location may include a related location of the power supply system 20, the power supply monitoring and adjusting system 30, or a related location of a mobile phone, a cloud database, a display device, or the like.

The power supply system 20 is configured to supply power to the load system 900. The power supply system 20, as shown in fig. 2, may further include a battery power terminal 201 and a utility power terminal 202. The battery power terminal 201 and the utility power terminal 202 are respectively configured to supply power to the load system 900.

In detail, the battery power (DC power, DC) supplied from the battery power terminal 201 can be converted into Alternating Current (AC) to be supplied to the load system 900 through the power supply monitoring and adjusting system 30, and the battery power terminal 201 can be composed of at least one secondary battery and can include a power management substrate. The utility power (AC) supplied from the utility power terminal 202 can be rectified by the power supply monitoring and adjusting system 30 and then supplied to the load system 900. Utility power broadly refers to the power generated by a power company's power plants.

The power supply monitoring and adjusting system 30 is configured to monitor the power supply system 20 and the load system 900, and transmit the real-time monitoring data to the central operation management and control system 10 in a wired or wireless manner. The power supply monitoring and adjusting system 30, as shown in fig. 2, may further include a sensing unit 301, an information transmitting unit 302, and a power distribution regulating unit 303.

Therefore, the central operation management and control system 10 can be used for: according to the real-time monitoring data transmitted by the power supply monitoring and adjusting system 30, the power consumption state of the load system 900 is continuously calculated to enable the power supply monitoring and adjusting system 30 to make power distribution adjustment to the power supply system 20. Specifically, the central computing management system 10 first sets a target load power of the load system 900. For example, the target power consumption of the load may be set according to a power upper limit of a contract capacity of the utility power contracted by a power company by 0-20%. In addition, the load target power consumption can also be optimized according to historical data. The central computing management and control system 10 can obtain real-time monitoring data of the utility power terminal 202, the load system 900 and the battery power terminal 201, such as real-time voltage, current, power, temperature, time, etc., through the power supply monitoring and control system 30. Then, the central operation management and control system 10 can determine whether the actual load power consumption of the load system 900 is higher than the set target load power consumption according to the obtained real-time monitoring data.

In a preferred embodiment, when the central operation control system 10 determines that the actual load power of the load system 900 is not higher than the set load target power according to the obtained real-time monitoring data, which indicates that there is some usage space for surplus utility power, the central operation control system 10 can charge the battery power terminal 201, for example, the utility power (AC, AC) provided by the utility power terminal 202 is converted into Direct Current (DC) by the power supply monitoring and controlling system 30 and then provided to the battery power terminal 201 for charging, but the sum of the maximum charging power of the battery power terminal 201 and the actual load power of the load system 900 is not larger than the set load target power.

In a preferred embodiment, when the central operation management and control system 10 determines that the actual load power of the load system 900 is not higher than the set load target power and lower than 30% of the set load target power according to the obtained real-time monitoring data, which indicates that there is sufficient space for using the utility power, the central operation management and control system 10 can charge the battery power terminal 201, but the sum of the maximum charging power of the battery power terminal 201 and the actual load power of the load system 900 is not larger than the set load target power.

In a preferred embodiment, when the central computing management and control system 10 determines that the actual load power consumption of the load system 900 is not higher than the set target load power consumption according to the obtained real-time monitoring data, the central computing management and control system 10 may charge the battery power end 201, but the maximum charging power of the battery power end 201 and the average power of the actual load power consumption of the load system 900 in a predetermined period (e.g., every 15 minutes or every 30 minutes) are not greater than the set target load power consumption, so that the battery power end 201 can be fully charged by effectively using the utility power, and the payment of the over-charge power rate can be avoided.

In a preferred embodiment, when the central computing management and control system 10 determines that the actual load power of the load system 900 is not higher than the set load target power but is close to 80% (the first percentage) to 95% (the second percentage) of the set load target power, i.e. the emergency warning is sent out by wire or wirelessly, and is close to 95% (the second percentage) or more of the set load target power, the central computing management and control system 10 turns off the charging of the battery power terminal 201 and discharges the battery power terminal 201 to adjust the power supply of the utility power terminal 202 so that the power supply of the utility power terminal 202 is not greater than the set load target power. Therefore, the emergency power-off condition of the commercial power end 202 due to self-protection can be avoided, and the emergency warning signal can be sent out in a wired or wireless manner, so that the user has buffering time to adjust the power consumption of the load.

It should be noted that if the utility power terminal 202 is powered off, the power can be provided from the battery power terminal 201, but the battery power terminal 201 is set to discharge at most to a discharge upper limit, and records and issues an alarm.

In a preferred embodiment, when the central computing management and control system 10 determines that the actual load power consumption of the load system 900 is higher than the set load target power consumption according to the obtained real-time monitoring data, the central computing management and control system 10 turns off the charging of the battery power terminal 201 and discharges the battery power terminal 201 to adjust the power supply of the utility power terminal 202 such that the average power supply of the utility power in a predetermined period (e.g. every 15 minutes or every 30 minutes) is lower than the set load target power consumption. Therefore, although the actual load power consumption of the load system 900 is already higher than the set target load power consumption, if the average power supply power of the utility power end 202 in a predetermined period, for example, every 15 minutes or every 30 minutes, is not greater than the set target load power consumption, the payment of the excess power rate can be avoided without reducing the load power consumption, and the power rate can be effectively saved.

In a preferred embodiment, after the battery power terminal 201 is discharged, when the central computing management and control system 10 determines that the power consumption of the load is continuously increased according to the obtained real-time monitoring data, the battery power terminal 201 is discharged at most to an upper discharge limit, and records and sends out an alarm.

In addition, the central operation control system 10 can integrate the real-time monitoring data provided by the power monitoring and controlling system 30 into the historical data of each day/week/month/season/year, etc. Furthermore, the history data may be stored in the storage unit 102, but may also be stored in a remote device, a portable device, etc. for the user to refer to. In addition, the central operation control system 10 may also perform simulation operation according to the historical data to obtain the optimized load target power consumption, so as to adjust the currently set load target power consumption according to the optimized load target power consumption. Therefore, the central operation management and control system 10 automatically calculates the optimized load target power consumption meeting the user requirement according to the historical data related to the past power consumption of the load system 900, so that the power cost of the user can be reduced, and the power cost can be effectively saved. Moreover, the system can be matched with power generation peak transfer of a power plant, so that the peak power consumption is reduced, the power utilization efficiency is improved, and the invalid occurrence of the power plant is reduced.

From the above preferred embodiments, the present invention can be summarized as an intelligent electric charge saving control method, wherein the flow chart is shown in fig. 3, and please refer to fig. 1 and fig. 2. The intelligent electricity-saving rate control method of the embodiment is suitable for an intelligent electricity-saving rate control system (for example, the intelligent electricity-saving rate control system of the above embodiment).

First, in step S103, the central arithmetic and control system 10 is instructed to set the load target power consumption of the load system 900. For example, the target load power may be set according to a power upper limit of a contract capacity of the utility power contracted by a power company, which is adjusted by 0-20%, for example, the contract capacity is contracted to supply a power upper limit of 180KW to a user, and the target load power is set to 144-180 KW. In addition, the load target power consumption may be adjusted based on an optimized load target power consumption derived from historical data regarding past power consumption of the load system 900. In addition, the power supply capacity of the secondary battery of the battery power terminal 201 can be increased to further improve the power utilization efficiency.

Next, in step S105, the central operation management and control system 10 obtains real-time monitoring data of the utility power 202, the load system 900 and the battery power 201 through the power supply monitoring and adjusting system 30. For example, the real-time monitoring data may include real-time voltage, current, power, temperature, time, etc. data of the utility power terminal 202, the load system 900, and the battery power terminal 201. Moreover, the real-time monitoring data can be transmitted to the central operation management and control system 10 in a wired or wireless manner.

Then, in step S107, the central arithmetic and control system 10 determines whether the actual load power consumption of the load system 900 is higher than the set target load power consumption based on the acquired real-time monitoring data.

In the present embodiment, if the determination result in step S107 is no, that is, if it is determined that the actual load electric power of the load system 900 is not higher than the set load target electric power, step S109 is executed to charge the battery power terminal 201, but the sum of the maximum charging power of the battery power terminal 201 and the actual load electric power of the load system 900 is not greater than the set load target electric power.

In a preferred embodiment, if the determination result in step S107 is no, that is, if it is determined that the actual load electric power of the load system 900 is not higher than the set load target electric power and is lower than 30% of the set load target electric power, the battery electric terminal 201 is charged, but the sum of the maximum charging power of the battery electric terminal 201 and the actual load electric power of the load system 900 is not greater than the set load target electric power.

In a preferred embodiment, if the determination result in step S107 is negative, that is, it is determined that the actual load electric power of the load system 900 is not higher than the set load target electric power, the battery power terminal 201 is charged, but the average power of the maximum charging power of the battery power terminal 201 and the actual load electric power of the load system 900 in a predetermined period is not higher than the set load target electric power.

In a preferred embodiment, if the determination result in step S107 is no, that is, if it is determined that the actual load power of the load system 900 is not higher than the set load target power, but is close to 80% to 95% of the set load target power and is close to 95% or more, the battery power terminal 201 is not charged, and on the contrary, the battery power terminal 201 is turned off from charging and the battery power terminal 201 is discharged to adjust the power supplied from the utility power terminal 202 so that the power supplied from the utility power terminal 202 is not higher than the set load target power.

In the present embodiment, if the determination result in step S107 is yes, that is, if it is determined that the actual load power of the load system 900 is higher than the set load target power, step S111 is executed to turn off the charging of the battery power terminal 201 and discharge the battery power terminal 201 to adjust the power supplied from the utility power terminal 202 so that the average power supplied from the utility power terminal 202 in a predetermined period is lower than the set load target power.

Further, after the battery power terminal 201 is discharged, if it is determined that the actual load power of the load system 900 is still continuously increased, the battery power terminal 201 is discharged at most to an upper discharge limit, and a warning signal is recorded and sent, so as to avoid affecting the service life of the battery.

In summary, the system and method for intelligently managing and controlling electricity saving rate provided by the invention can monitor the load power consumption at any time, regulate and control the power supply of the commercial power end and the battery power end, avoid paying expensive over-contract electricity rate under the condition of not reducing the load power consumption, and effectively save the electricity rate.

The disclosure is only a preferred embodiment of the invention and is not intended to limit the scope of the invention, so that all equivalent variations using the contents of the present specification and drawings are included in the scope of the invention.
