Due to the widespread use of distributed energy storage, it is necessary to bill and settle distributed energy storage.

[0003] In the prior art, the following two methods are generally used to bill and settle distributed energy storage: Method 1: offline meter reading is used for billing and settlement; Method 2: in the peak and valley power periods of the equipment in the smart meter, after each peak power period or valley power period ends, the power usage information and electricity fee data of this period are sent to the billing and settlement system; when using method 1, it is time-consuming and laborious to check regularly, and human verification errors may occur; when using method 2, although there is no need for manual regular verification, when the peak power period, valley power period or electricity price changes, it is necessary to manually go to the smart meter section to re-set it, and because the peak power period or valley power period is set at the smart meter end, and it needs to be reported after the peak power period or valley power period ends, the real-time nature of the billing and settlement cannot be guaranteed, and once the reporting time is not correctly reported due to communication abnormalities and other reasons, the accuracy of the billing and settlement cannot be guaranteed.

[0076] The present invention is described below based on the embodiments, but the present invention is not limited to these embodiments. In the detailed description of the present invention below, some specific details are described in detail. It is possible for a person skilled in the art to fully understand the present invention without the description of these details. In order to avoid confusing the essence of the present invention, known methods, processes, procedures, components and circuits are not described in detail.

[0077] In addition, persons of ordinary skill in the art will appreciate that the drawings provided herein are for illustration purposes and are not necessarily drawn to scale.

[0078] Unless the context clearly requires otherwise, the words "include", "comprising" and similar words throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, the meaning is "including but not limited to".

[0079] In the description of the present invention, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0080] The embodiments of the present invention relate to energy storage, energy storage settlement and real-time accurate billing. The energy storage, energy storage settlement and real-time accurate billing are briefly explained below, as follows:

[0081] The energy storage mentioned here refers to distributed electric energy storage (also called distributed energy storage), which is the distributed installation of energy storage devices (also called distributed energy storage devices) in the power grid. Electric energy is stored and managed through distributed energy storage devices to improve the supply and demand balance of the power system, peak shifting and valley filling, and improve stability and power quality. Compared with centralized energy storage, it has higher reliability, flexibility and response speed. Distributed power energy storage equipment is usually installed next to the power load (i.e., power-consuming equipment), and works in coordination with renewable energy power generation equipment (e.g., photovoltaic power generation equipment) or traditional power generation equipment to store and provide electricity. Its advantages lie in convenient dispatching, low operating costs, and high technical maturity. In addition, distributed power storage can further improve the quality and sustainability of electricity by reducing load peaks, while reducing the demand for transmission and distribution facilities. Energy storage settlement (also known as billing settlement): The electricity generated by the services provided by energy storage equipment to the outside world is priced and settled through electronic channels such as the Internet. At present, in addition to policy subsidies, energy storage operations mainly rely on peak-valley price differences for profit, that is, energy storage equipment is charged during low-valley electricity price periods, and electricity is released as red dots for power load during peak electricity price periods. Finally, the comprehensive settlement results in energy storage operation profit. Real-time and accurate billing: It means that at a real-time moment, the power information of offline energy storage equipment can be obtained and processed in a timely and accurate manner, and billed in combination with the latest peak and valley electricity price periods and electricity prices released by the power grid.

[0082] Usually in the prior art, the following two methods are generally used to bill and settle distributed energy storage. Method 1: offline meter reading is used for billing and settlement. Method 1 requires manual time-consuming and laborious regular verification, and human verification errors may occur. For example, every 4 hours, 12 hours or 24 hours, the staff will conduct offline meter reading. Due to the large number of energy storage devices, each energy storage device corresponds to an electricity meter. Therefore, the workload of the staff for each meter reading is very large, and the efficiency is low, and meter reading errors may occur. Method 2: During the peak and valley power periods of the equipment in the smart meter, after each peak power period or valley power period ends, the power usage information and electricity fee data of this period are sent to the billing and settlement system; for example, the peak power period is from 8 am to 5 pm At 10 noon, after the peak electricity period ends, the smart meter sends the electricity consumption information of the peak electricity period to the billing and settlement system, or the smart meter also sets the electricity price, and the smart meter calculates the electricity charge data according to the above electricity consumption information and the electricity price, and sends the electricity charge data to the billing and settlement system. When the second method is adopted, although there is no need for manual regular verification, when the peak electricity period, the off-peak electricity period or the electricity price changes, it is necessary to manually go to the smart meter section to re-set it, and because the peak electricity period or the off-peak electricity period is set at the smart meter end, and it needs to be reported after the peak electricity period or the off-peak electricity period ends, the real-time billing and settlement cannot be guaranteed, and once the reporting time is not correctly reported due to communication abnormalities or other reasons, the accuracy of the billing and settlement cannot be guaranteed.

[0083] Therefore, how to ensure the real-time and accuracy of billing and settlement in distributed energy storage is a problem that needs to be solved at present.

[0084] In an embodiment of the present invention, in order to solve the above problems, a distributed energy storage device billing and settlement system is proposed. The schematic diagram of the distributed energy storage device billing and settlement system is as follows: Figure 1 As shown, specifically including:

[0085] An energy storage cloud operation platform 101 , an energy storage device system 102 and at least one energy storage device 103 .

[0086] Specifically, the energy storage cloud operation platform 101 is used to obtain the power information of the at least one energy storage device through the energy storage device system, wherein the power information includes real-time power, stage power and cycle power. The energy storage cloud operation platform is also used to obtain electricity price information and perform billing and settlement according to the power information and the electricity price information; the energy storage cloud operation platform exchanges data with the energy storage device system through the network; the energy storage device system 102 communicates with the at least one energy storage device to record and send the power information of the at least one energy storage device, and the energy storage device system exchanges data with the energy storage cloud operation platform and the energy storage device through the network; the at least one energy storage device 103 is used for charging and discharging.

[0087] In the embodiment of the present invention, Figure 2 It is a schematic diagram of another distributed energy storage device billing and settlement system according to an embodiment of the present invention. Specifically, the energy storage cloud operation platform 101 specifically includes: an electricity price management unit 1011, an energy storage power management unit 1012 and a billing and settlement unit 1013; the energy storage device system 102 includes at least one smart meter, each smart meter corresponds to an energy storage device, and is used to record the power information of the energy storage device.

[0088] Specifically, the electricity price management unit 1011 is used to obtain electricity price information queried from the electricity price query system, or to obtain electricity price information preset by the user, wherein the electricity price information queried from the electricity price query system is the latest electricity price provided by the State Grid. If the electricity price information cannot be queried from the electricity price query system, the electricity price management platform can also pre-set the electricity price information by manual input. In the embodiment of the present invention, a time-of-use electricity price diagram within 24 hours is as follows Figure 3As shown, taking November as an example, the time-of-use electricity price is the same every day in November, and the electricity price model is a multiple rate. The rate segments shown include peak, high and low prices. The peak price is 1.2861 yuan / kwh, the peak price is 1.0742 / kwh, and the low price is 0.3434 yuan / kwh. The peak period is 09:00:00-11:00:00; 15:00:00-17:00:00, the peak period is 08:00:00-09:00:00; 13:00:00-15:00:00; 17:00:00-22:00:00, and the low period is The time periods are 11:00:00-13:00:00; 22:00:00-23:59:59; 10:00:00-08:00:00. The time period division and electricity price in the time-sharing electricity price diagram here are determined according to actual conditions, and the embodiment of the present invention does not limit it. In the embodiment of the present invention, the change and adjustment of the peak and valley electricity price time periods are actively obtained by the electricity price management unit and updated in time, ensuring the accuracy of the most critical peak and valley electricity price time periods and electricity price information in billing. The embodiment of the present invention also includes peak electricity price time periods and electricity prices. For the convenience of description, only the peak and valley electricity price time periods and electricity prices are reflected.

[0089] In a possible implementation, the energy storage power management unit 1012 is used to obtain power information of the at least one energy storage device through the energy storage device system, specifically including: every first set time, the energy storage power management unit obtains the real-time power of the at least one energy storage device through the energy storage device system; every second set time, the energy storage power management unit obtains the stage power of the at least one energy storage device through the energy storage device system; every third set time, the energy storage power management unit obtains the cycle power of the at least one energy storage device through the energy storage device system; for example, the energy storage device system reports the real-time power once every 10 seconds, that is, the energy storage cloud operation platform reports the real-time power once every 10 seconds. The real-time power of at least one energy storage device is obtained through the energy storage device system; the energy storage device system reports the stage power once every 15 minutes, that is, the energy storage cloud operation platform obtains the stage power of at least one energy storage device through the energy storage device system every 15 minutes; the energy storage device system reports the cycle power once every 24 hours, that is, the energy storage cloud operation platform obtains the cycle power of at least one energy storage device through the energy storage device system every 24 hours, wherein, when the energy storage device system reports the stage power once every 15 minutes, the cycle power is the accumulation of 96 stage powers in the previous 24 hours; the above time is only an exemplary description, and the reporting interval is determined according to actual use.

[0090] In the embodiment of the present invention, since only the power consumption needs to be reported, the reported data is simple, efficient, and can ensure real-time performance, with a maximum delay of no more than 10 seconds, and can be supported by ordinary metering meters with data transmission function.

[0091] In a possible implementation, the billing settlement unit 1013 is used to perform multiple billing settlements based on the power consumption information and the electricity price information. Specifically, the billing settlement unit performs billing settlement based on the real-time power consumption and the electricity price information; in response to changes in the electricity price information, the billing settlement unit performs preliminary billing settlement updates based on the stage power consumption and the electricity price information; the billing settlement unit performs final billing settlement updates based on the periodic power consumption and the electricity price information.

[0092] In an embodiment of the present invention, the energy storage power management unit receives real-time power, for example, the real-time power in the time period of 14:00:00-14:00:10, determines the electricity price in the time period, and then performs billing and settlement for the time period; after the energy storage power management unit receives the stage power, for example, the stage power in the time period of 14:00:00-14:15:00, determines the electricity price in the time period (for example, the electricity price in the time period changes), then performs a preliminary billing and settlement update for the time period, and calibrates the power in the time period; after the energy storage power management unit receives the periodic power, for example, the stage power in the time period of 00:00:00 on the same day to 00:00:00 on the next day, determines the electricity prices of multiple stages in the time period (for example, the electricity price in the time period changes), then performs another billing and settlement update for the time period, and calibrates the power in the time period.

[0093] In the embodiment of the present invention, the above system can not only perform real-time billing, but also perform secondary billing settlement update, thereby meeting the real-time and accuracy of billing settlement.

[0094] In a possible implementation, the energy storage device system includes at least one smart meter, wherein each smart meter is used to record and send power information of a corresponding energy storage device.

[0095] Assume that the energy storage device system includes 5 smart meters, each smart electricity corresponds to a smart device, and for each smart meter, each of the smart meters records and sends the real-time electricity of the corresponding energy storage device at a first set time; each of the smart meters records and sends the stage electricity of the corresponding energy storage device at a first set time; each of the smart meters records and sends the periodic electricity of the corresponding energy storage device at a first set time.

[0096] In the embodiment of the present invention, each of the energy storage devices is used to charge during off-peak electricity price periods and discharge during peak electricity price periods. During peak electricity price periods, the energy storage device can be charged or discharged according to actual conditions, which is determined based on actual conditions.

[0097] The relationship between the charging and discharging of the energy storage device, the load power consumption, the time-of-use electricity price and the remaining power of the energy storage device is described in detail below through a specific embodiment, as shown in Figures 4(a) and 4(b). Figure 4(a) is a schematic diagram of the charging and discharging of an energy storage device according to an embodiment of the present invention. Specifically, Figure 4(a) takes the 00:00-17:30 period as an example. When the power value is a positive value, it indicates that the energy storage device is charging; when the power value is a negative value, it indicates that the energy storage device is discharging; the load power consumption is always positive; Figure 4(b) is a schematic diagram of the time-of-use electricity price and the remaining power of the energy storage device according to an embodiment of the present invention; Figure 4(b) takes the 00:00-17:30 period as an example. In the 00:00-07:30 period, the time-of-use electricity price is relatively low. , the remaining power soc of the energy storage device gradually increases until it reaches 100%. In the period of 07:30-10:00, the remaining power soc remains unchanged at 100% during the peak electricity price. In the period of 10:00-12:00, the remaining power soc gradually decreases to 20% during the peak electricity price, that is, the storage device is used to supply power to the power load during this period. In the period of 12:00-13:35, the remaining power soc gradually increases during the peak electricity price until it reaches 100%, that is, the storage device is used to charge during this period. In the period of 13:35-14:00, the remaining power soc remains unchanged at 100% during the peak electricity price. In the period of 14:00-15:30, the remaining power soc gradually decreases to 0% during the peak electricity price, that is, the storage device is used to supply power to the power load during this period.

[0098] In the embodiment of the present invention, from the perspective of the energy storage cloud operation platform, Figure 5 This is a flow chart of a method for billing and settlement of distributed energy storage equipment according to an embodiment of the present invention, and the specific steps are as follows:

[0114] Step S702: Send periodic power to the energy storage cloud operation platform every third set time.

[0115] For example, every 24 hours (hour) or 48 hours, the energy storage device system sends periodic electricity to the energy storage cloud operation platform. If the third setting time is 24 hours, the periodic electricity can also be called daily electricity. The third setting time is determined according to actual conditions and is not limited in the embodiment of the present invention.
