DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0023] According to an embodiment of the present invention, an embodiment of a method for regulating and scheduling a distributed power source is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0024] In this embodiment, a distributed power supply control and scheduling method is provided, which can be used in a data interaction module in an electric energy meter. Figure 1 is a flow chart of a method for regulating and dispatching a distributed power source according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps: Step S101, receiving a control and dispatching plan for distributed power sources in a future preset period of time.

[0025] Step S102: generating a distributed power supply control and scheduling plan table according to the control and scheduling scheme.

[0026] Step S103: performing real-time regulation and scheduling on the distributed power source according to the distributed power source regulation and scheduling plan table.

[0027] Specifically, in the relevant technology, in order to realize intelligent sensing data interaction, a data interaction module is usually set in the smart IoT electric energy meter. The smart IoT electric energy meter is an advanced electric energy metering device that integrates the Internet of Things technology. It has the characteristics of high-precision metering, remote over-metering, real-time monitoring, fault diagnosis, time-sharing billing, load management and two-way communication. In actual applications, the smart IoT electric energy meter is connected to the distributed power source. The data interaction module in the smart IoT electric energy meter can realize the data interaction between the electric energy meter and the corresponding connected distributed power source such as photovoltaic equipment, and realize the observable, measurable and controllable distributed power source. Among them, the data interaction module can respond to the instructions of the upper-level equipment and adjust the power generation of the distributed power source according to the instructions. However, this method needs to receive the instructions for parsing before adjustment, and the real-time performance is poor.

[0028] Therefore, the above-mentioned distributed power supply regulation and scheduling method can be executed in the data interaction module. The data interaction module first receives the regulation and scheduling plan for the distributed power supply in the future preset time period. For example, it can receive the regulation and scheduling plan for the distributed power supply in the next week or the next month, and parse the regulation and scheduling plan to generate a distributed power supply regulation and scheduling schedule. When the corresponding regulation and scheduling time is reached, the corresponding regulation and scheduling plan can be directly executed according to the schedule, which is more real-time.

[0029] This embodiment provides a method for regulating and dispatching distributed power sources, which receives a regulation and dispatching plan for distributed power sources in a preset period of time in the future in advance, analyzes the plan and generates a regulation and dispatching schedule, so that real-time regulation can be performed directly according to the schedule during regulation, avoiding the problem of poor real-time performance when obtaining the regulation and dispatching plan during regulation. Based on this, the method improves the flexibility of distributed power regulation by setting a distributed power regulation and dispatching schedule.

[0030] In this embodiment, a method for regulating and scheduling a distributed power source is provided, and the process includes the following steps: Step S201: receiving a control and dispatching plan for distributed power sources in a future preset period of time.

[0031] Step S202: Generate a distributed power supply control and scheduling plan table according to the control and scheduling scheme.

[0032] Specifically, the above step S202 includes: Step S2021, generating at least one control and scheduling plan unit according to the device that sends the control and scheduling scheme and the corresponding control and scheduling scheme, and the device that sends the control and scheduling scheme includes any one of a scheduling system, a master station or a concentrator.

[0033] Step S2022: Generate a distributed power supply control and scheduling plan table according to at least one control and scheduling plan unit.

[0034] Specifically, when generating a distributed power supply control and scheduling plan table, one or more control and scheduling plan units can be generated according to the device that sends the control and scheduling plan and the source of the control and scheduling plan. For example, when there is only one device that sends the control and scheduling plan, only one control and scheduling plan unit can be generated; when there are multiple devices that send the control and scheduling plan, multiple control and scheduling plan units can be generated. The device that sends the control and scheduling plan can be any one of the scheduling system, the master station or the concentrator. Specifically, when the scheduling system, the master station and the concentrator all send the control and scheduling plan to the data interaction module, corresponding control and scheduling plan units can be generated for the control and scheduling plans sent by the scheduling system, the master station and the concentrator respectively.

[0035] The dispatching system may be a power dispatching system or a power grid dispatching system, which can manage and control the operation of the power system, for example, it can monitor, coordinate and control the power generation, transmission and distribution processes, and determine the stability and reliability of the power system. Thus, the dispatching system can obtain the power demand of the power grid in advance, such as the peak and valley periods of the power grid, and pre-generate corresponding control and dispatching plans for different periods, and send the control and dispatching plans to the data interaction module in the electric energy meter.

[0036] The master station or concentrator can manage the data of the energy meter, so the master station or concentrator can generate a control and dispatching plan in advance based on the analysis of the collected energy meter data. For example, the historical data of the collected energy meter can be analyzed and processed using statistical analysis and machine learning algorithms to generate a control and dispatching plan.

[0037] In an optional implementation, the above step S2021 includes: Step a1, extracting the access port, control period and control data in the control and scheduling scheme, wherein the access port includes the address of the distributed power source to be regulated and scheduled.

[0038] Step a2: Generate a control period table and a control data table according to the control period and the control data respectively.

[0039] Step a3: generating a control scheduling plan unit according to the access port, the control period table, the control data table and the device sending the control scheduling plan.

[0040] Specifically, for the received control and scheduling scheme, which contains the specifically controlled and scheduled distributed power source, it can be extracted from the control and scheduling scheme, and an access port is generated and saved in the control and scheduling plan unit. For example, when the distributed power source is a photovoltaic device, the access port can be the slave address of the photovoltaic device.

[0041] In addition, for the regulation of distributed power sources, different regulation methods may be used at different times of the day. Therefore, the specific regulation and scheduling scheme can be divided into different regulation periods according to the different regulation methods in the regulation and scheduling scheme, and different regulation periods correspond to different regulation data. A regulation period table and a regulation data table can be formed for the regulation period and the corresponding regulation data, respectively. Among them, the regulation period table includes: at least one regulation period, the regulation period includes the start time and end time of the regulation and scheduling, and the regulation data table includes at least one regulation data unit, each regulation data unit includes the regulation data corresponding to each regulation period.

[0042] Specifically, the control data includes: a control type, at least one control method and a corresponding control value, wherein the control method includes any one or more of active power, reactive power, power factor, active power percentage and reactive power percentage. Based on these control data, in this embodiment, by setting specific control values ​​of parameters such as active power, reactive power, power factor, active power percentage and reactive power percentage, when the distributed power source is controlled and dispatched, it can be adjusted directly according to the control values ​​of the corresponding parameters. In other implementations, the control values ​​of other parameters can be further set.

[0043] The control types include close first and open later, open first and close later, close first and close later, and open first and open later. Specifically, the close first and open later and open first and close later in the control type accurately divide the time points in the control period, and clarify how to control the handover time points of the two periods. For example, the rated active power of the distributed power source is 100kw. The first period is 9:00-10:00, and the active power is required to be adjusted to 50kw. The second period is 10:00-11:00, and the active power is required to be adjusted to 80kw. Then, for which period of control result is executed at 10:00, it depends on the control type in the schedule. If the control type is close first and open later, the control result of the second period is executed at 10:00, that is, 80kw; if the control type is open first and close later, the control result of the first period is executed at 10:00, that is, 50kw. In addition, "close first, close second" and "open first, open second" are the control types used when controlling the control period without a handover time point; for example, for two control periods, the first period is 9:00-10:00, and the active power is required to be adjusted to 50kw. The second period is 11:00-12:00, and the active power is required to be adjusted to 80kw. If the control type is "close first, close second", the control result of the first period, that is, 50kw, will be executed at 10:00; if the control type is "open first, open second", the rated active power, that is, 100kw, will be restored at 10:00. This helps to achieve precise control at the minute level and avoids the problem of inconsistent control at crossover times.

[0044] In an optional implementation, the above step a3 includes: Step b1, determining the plan source according to the device that sends the control and scheduling plan, and generating the serial number of the control and scheduling plan unit.

[0045] Step b2, extracting the control plan execution date in the control scheduling scheme.

[0046] Step b3, generating a control scheduling plan unit according to the serial number, the plan source, the access port, the control plan execution date, the control time period table and the control data table.

[0047] Specifically, since multiple control and scheduling plan units are generated when generating the control and scheduling plan, and different control and scheduling plan units have different sources, the plan source can be determined according to the device that sends the control and scheduling plan, and the serial number of the control and scheduling plan unit can be generated. At the same time, when generating the control and scheduling plan unit, the serial number and the plan source can be added thereto. In addition to the control and scheduling period, the specific control and scheduling plans for different seasons may also be different. Therefore, the control plan execution date in the control and scheduling plan is further extracted, that is, the year, month and day of the specific control, and the control plan execution date is also added to the control and scheduling plan unit.

[0048] In an optional implementation, after the above step S2022, the method further includes: Step S2023, add, update or delete the control and scheduling plan unit according to the newly received control and scheduling scheme. Specifically, the generated control and scheduling plan unit can be further adjusted according to the actual situation. For example, the control and scheduling plan unit that has been generated contains control data for one or several control time periods, and the newly received control and scheduling scheme also contains the control data for the corresponding control time period, but the specific control data is different. At this time, the corresponding control and scheduling plan unit can be updated or deleted according to the newly received control and scheduling plan unit. At the same time, for the control data for the control time period that was not originally included in the newly received control and scheduling scheme, a new control and scheduling plan unit can be added, thereby realizing flexible configuration of the schedule.

[0049] Step S203: performing real-time regulation and scheduling on the distributed power source according to the distributed power source regulation and scheduling plan table.

[0050] The further functional description of each of the above steps is the same as that of the above corresponding embodiments and will not be repeated here.

[0051] In this embodiment, a data interaction module applied to an electric energy meter is provided, such as Figure 2As shown, the data interaction module includes: The receiving module 21 is used to receive a control and dispatching plan for distributed power sources in a future preset period of time.

[0052] The schedule generating module 22 is used to generate a distributed power supply control and scheduling schedule according to the control and scheduling scheme.

[0053] The control and scheduling module 23 is used to perform real-time control and scheduling of the distributed power source according to the distributed power source control and scheduling plan table.

[0054] In an optional embodiment, the distributed power supply control and scheduling plan table includes: at least one control and scheduling plan unit, each control and scheduling plan unit is generated according to the device that sends the control and scheduling plan and the corresponding control and scheduling plan, and the control and scheduling device includes any one of a scheduling system, a master station or a concentrator.

[0055] The control and scheduling planning unit includes: a control period table and a control data table, the control period table includes: at least one control period, the control period includes the start time and end time of the control scheduling, the control data table includes at least one control data unit, each control data unit includes the control data corresponding to each control period.

[0056] The control data includes: a control type, at least one control method and a corresponding control value, and the control method includes any one or more of active power, reactive power, power factor, active power percentage and reactive power percentage.

[0057] The control and scheduling plan unit also includes a serial number, an access port, a plan source and a control and scheduling execution date, the serial number includes the number of the control and scheduling plan unit, the access port includes the address of the distributed power source to be regulated and scheduled, the plan source includes the sending control and scheduling device, and the control and scheduling execution date includes the year, month and day when the control and scheduling plan is executed.

[0058] The control and scheduling planning unit adds, updates or deletes according to the received control and scheduling scheme.

[0059] Specifically, when the distributed power source includes photovoltaic equipment, the distributed power source control and scheduling plan table is composed of one or more distributed power source control and scheduling plan units, specifically including the following contents: Serial number: used to set the distributed power supply control and scheduling planning unit number to facilitate the management of the planning unit.

[0060] Access port: used to set the slave address of the photovoltaic device, indicating which photovoltaic device the control and scheduling planning unit is applied to.

[0061] Plan source: used to set the source of the control and scheduling plan unit to achieve the control and scheduling of photovoltaic equipment by various devices through the module.

[0062] PV control plan execution date: used to set the execution date of the control and scheduling plan unit to facilitate the refined control of PV equipment.

[0063] Photovoltaic output control period table: can contain one or more photovoltaic output control periods.

[0064] Photovoltaic output control period: used to set the specific time period for controlling photovoltaic equipment, so as to achieve precise control of photovoltaic equipment.

[0065] Control data table: can contain one or more control data units.

[0066] Control data unit: can contain one or more control methods and their control values.

[0067] Adjustment method: Set the specific adjustment method for regulating the photovoltaic equipment to facilitate the precise regulation of the photovoltaic equipment.

[0068] Adjustment value: Set the specific adjustment data for regulating the photovoltaic equipment to facilitate the precise regulation of the photovoltaic equipment.

[0069] Based on the above content, the distributed power supply control and scheduling planning unit can be set according to the following method and Table 1, where Table 1 is the distributed power supply adjustment method and the corresponding adjustment value. Specifically, the distributed power supply control and scheduling planning unit is expressed as follows: Control and Scheduling Planning Unit::=structure { Sequence number long-unsigned, Access port is unsigned, Schedule source enum {scheduling system (1), master station (2), concentrator (3), other (255)}, PV control plan implementation date, Photovoltaic output control period table array Photovoltaic output control period } Photovoltaic output control period ∷=structure { Type enum { Close before opening (0), Front open and back closed (1), Front closed and back closed (2), Front opening and back opening (3) }, Time period ∷ = structure { start hour unsigned, Starting minute unsigned, End hour unsigned, End minute unsigned }, Control data table array control data unit } Control data unit:=structure { Adjustment method::enum { Active power (1), Reactive power (2), Power factor (3), Active power percentage (4), Reactive power percentage (5) }, Adjustment valueData } Table 1

[0070] In an optional implementation, when the distributed power source is a photovoltaic device, the data interaction module is also called a photovoltaic device data interaction module, and its access point in the entire power system is as follows: Figure 3 and Figure 4 As shown. Among them, Figure 3 An electrical architecture diagram showing the low-voltage distributed photovoltaic consumption method. The power generation of photovoltaic equipment needs to be settled at the property boundary point. Figure 4 It represents the photovoltaic collection communication networking solution, and clearly describes the topological structure for monitoring and controlling photovoltaic inverter equipment.

[0071] like Figure 3As shown in the figure, low-voltage distributed photovoltaic systems can be divided into three types according to different consumption methods: full grid-connected, balance grid-connected and energy storage. Among them, in the full grid-connected mode, all the electricity generated by the photovoltaic system is directly transmitted to the public power grid. The photovoltaic system includes a photovoltaic array composed of photovoltaic components and an inverter. The photovoltaic components convert solar energy into direct current, and the inverter converts direct current into alternating current. The power generated by the photovoltaic system is collected by an intelligent IoT electric energy meter, that is, an intelligent IoT electric energy meter can be installed at the property boundary point. The intelligent IoT electric energy meter has an embedded photovoltaic equipment data interaction module to realize the regulation and scheduling of the photovoltaic system. A photovoltaic special circuit breaker is also set between the intelligent IoT electric energy meter and the photovoltaic system to realize overload protection, overvoltage protection, DC protection and isolation of the photovoltaic system. In addition, this mode also includes a photovoltaic grid-connected box, which is used to provide a standardized grid-connected interface and has protection and monitoring functions. The data collected by the intelligent IoT electric energy meter is uploaded to the monitoring center through intelligent measurement switches and concentrators. And the power generated by the photovoltaic system can be transmitted to the power grid through a transformer.

[0072] In the surplus power access mode, the electricity generated by the photovoltaic system is first supplied to the local load, and the excess is then transmitted to the public power grid. In the energy storage mode, the electricity generated by the photovoltaic system can not only be directly supplied to the local load, but also stored in the battery. In this embodiment, the surplus power access mode and energy storage are combined. In this combined mode, the photovoltaic system including photovoltaic modules and photovoltaic inverters generates electricity, and the generated electricity can be supplied to the local power load, and the excess electricity can be stored in the energy storage system including energy storage batteries and energy storage converters. For local power loads, an electricity metering box can be set at the electricity metering point to record the actual electricity consumption of the user. For the electricity stored in the energy storage system, an energy storage grid connection box can be set at the energy storage grid connection point to achieve the management of the stored electric energy. The electric energy after supplying the local load and energy storage can be transmitted to the public power grid. At this time, a photovoltaic collection monitoring unit and an electric energy meter can be set at the property boundary point to realize the collection of the electricity generated by the photovoltaic system and the electricity transmitted to the power grid.

[0073] like Figure 4 As shown, for the above-mentioned low-voltage distributed photovoltaic system, when forming a communication network, RS-485, CAN, dual-mode and 4G can be used to realize data transmission. Among them, RS-485 or CAN communication can be used for the transmission between the energy meter and the photovoltaic inverter and the energy storage converter. For the communication between the concentrator and the energy meter, a dual-mode communication method can be used, for example, power line carrier communication and wireless communication can be used to realize communication. For the communication between the acquisition master station and the concentrator, 4G or other wireless communication methods can be used.
