Detailed implementation manners
[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer and more understandable, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Herein, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.
[0023] In the description of this specification, the terms "include", "comprise", "have", "contain", etc. are all open-ended terms, that is, they are intended to include but not limited to. The description with reference to terms such as "one embodiment", "one specific embodiment", "some embodiments", "for example", etc. means that the specific features, structures, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example.

The step sequences involved in each embodiment are used to schematically illustrate the implementation of the present application, and the step sequences are not limited and can be adjusted appropriately as needed.
[0024] After research, it is found that the existing power consumption scheduling methods for photovoltaic energy storage devices usually first obtain electricity prices, predict photovoltaic power generation, and predict loads, and then optimize the power consumption strategies for each time period based on the TOU mode (time-of-use power consumption mode), or perform power limit for each time period based on the energy flow. Since the generation process of the power consumption scheduling strategy needs to involve the acquisition, generation, and interaction of multiple parties' data, and has high requirements for the accuracy and real-time performance of the data, the existing power consumption scheduling strategy generation methods cannot ensure the real-time performance and accuracy of each data, resulting in a low accuracy of the finally obtained power consumption scheduling strategy.
[0025] Moreover, neither of these two power consumption scheduling methods takes into account the power consumption scheduling requirements in different users and different scenarios. For example, when optimizing the power consumption strategies for each time period based on the TOU mode, algorithms such as reinforcement learning and operations research optimization are mostly used to obtain better strategy combinations, but this method cannot control the charge and discharge power within the planned range, resulting in overcharging or over-discharging; when performing power limit for each time period based on the energy flow, the energy flow is optimized using the method of reinforcement learning or operations research optimization, which has extremely high requirements for the accuracy of photovoltaic power generation and load prediction, has a high tolerance for errors, and is prone to error accumulation. At the same time, the special settings of some users, such as peak shaving, backup power, charging pile scenarios, etc. will affect the priority of the energy flow in their scenarios, resulting in unexpected control results.
[0026] Based on this, an embodiment of the present invention provides a system for generating an electricity consumption scheduling strategy for a photovoltaic energy storage device.

In the embodiment of the present invention, the power price information can be obtained in real time through the power price acquisition module, the real-time device information of the photovoltaic energy storage device is collected through the site information acquisition module, the power generation information of the photovoltaic energy storage device is predicted through the power generation prediction module, the load information of the photovoltaic energy storage device is predicted through the load prediction module, the user demand configuration information of the user is obtained through the charge and discharge constraint module and the charge and discharge constraint conditions are generated, and the strategy generation module determines the optimal power consumption scheduling strategy based on the above data.

[0030] In the field of photovoltaic energy storage power generation, there are many types of power prices, and the power prices are also different, including various retailer power prices, power prices of the power grid system, etc. Therefore, in order to provide accurate power consumption scheduling strategies for users, it is necessary to ensure the real-time and accuracy of the power price information obtained by the power price acquisition module; based on this, the embodiment of the present invention provides a solution for obtaining power prices in multiple dimensions.
[0031] Figure 2 It is the structural diagram of the power price acquisition module provided by the embodiment of the present invention. As Figure 2 shown, the above-mentioned power price acquisition module 1 may specifically include: a first power price unit 11, a second power price unit 12, a third power price unit 13, a fourth power price unit 14, and a power price output unit 15: Among them, the first power price unit 11 is used to obtain the wholesale power price information from each power grid system and generate user power price information according to the wholesale power price information; The second power price unit 12 is used to obtain the retailer power price information from each retailer system; The third power price unit 13 is used to collect the power price information configured by the user; The fourth power price unit 14 is used to obtain the first preferential power price information from each power grid system and / or the second preferential power price information from each retailer system, and generate the designated user preferential power price information according to the first preferential power price information and / or the second preferential power price information; The electricity price output unit 15 is used to output the final user electricity price information based on at least one of the user electricity price information generated by the first electricity price unit, the retailer electricity price information obtained by the second electricity price unit, the electricity price information configured by the user collected by the third electricity price unit, and the specified user preferential electricity price information generated by the fourth electricity price unit.
[0032] In specific implementation, the above-mentioned first electricity price unit 11 can be docked with each power grid system to obtain the wholesale electricity price information from each power grid system in real time or regularly, and generate user electricity price information based on the wholesale electricity price information. Specifically, the wholesale electricity price information is the clearing wholesale price announced by each power grid system; the user electricity price information can include the electricity purchase price information and the electricity selling price information. Among them, the electricity purchase price information refers to the price when the user purchases electricity from the power grid system, and the electricity selling price information refers to the price when the user sells the electricity obtained from photovoltaic power generation to the power grid system. In specific applications, the user electricity price information can be formed by weighting the wholesale electricity price in a proportional or fixed value manner.
[0033] In one embodiment, the above-mentioned first electricity price unit 11 generates user electricity price information based on the wholesale electricity price information. Specifically, it can include: calculating the electricity purchase price in the user electricity price information according to the electricity purchase price calculation algorithm, in accordance with the preset electricity purchase ratio information and electricity purchase tax information, and combining the wholesale electricity price information; calculating the electricity selling price in the user electricity price information according to the electricity selling price calculation algorithm, in accordance with the preset electricity selling ratio information and electricity selling tax information, and combining the wholesale electricity price information.
[0034] In specific implementation, the above-mentioned electricity purchase ratio information, electricity purchase tax information, electricity selling ratio information, and electricity selling tax information can be filled in by the user through the user interface provided by the first electricity price unit, or can be automatically generated by the first electricity price unit according to information such as the region where the user is located and the electricity buying and selling rules in that region. There is no limitation here.
[0035] In specific implementation, according to the electricity purchase price calculation algorithm, to calculate the electricity purchase price, it can be achieved through the following formula: Electricity purchase price = (1 + input item 1) × wholesale electricity price + input item 2; Among them, input item 1 is the electricity purchase ratio information, input item 2 is the electricity purchase tax information, and the electricity purchase tax information can be a fixed value.
[0036] According to the electricity selling price calculation algorithm, to calculate the electricity selling price, it can be achieved through the following formula: Electricity selling price = (1 + input item 3) × wholesale electricity price + input item 4; Among them, input item 3 is the electricity selling ratio information, input item 4 is the electricity selling tax information, and the electricity selling tax information can be a fixed value.
[0037] In specific implementation, the above-mentioned second electricity price unit 12 can be connected to each retailer system to obtain retailer electricity price information from each retailer system in real time or regularly for customers to select. Specifically, the retailer electricity price information refers to the price at which an electricity sales company or electricity retailer sells electricity to end-users (such as residential, commercial, and industrial users).
[0038] In specific implementation, the above-mentioned third electricity price unit 13 can provide a user configuration interface to collect the electricity price information configured by the user. Specifically, the user can set the electricity price for each time period according to information such as hours, minutes, days, weeks, and months through the user configuration interface, and the third electricity price unit collects the time-of-use electricity price information set by the user.
[0039] In specific implementation, the above-mentioned fourth electricity price unit 14 can also be connected to each power grid system and each retailer system. The fourth electricity price unit can generate specified user preferential electricity price information according to the first preferential electricity price information of each power grid system and / or the second preferential electricity price information of each retailer system. For example, due to the active electricity trading in some areas, there may be sudden preferential package time periods. Therefore, the fourth electricity price unit can obtain real-time first preferential electricity price information and second preferential electricity price information from each power grid system and each retailer system through the interface, and automatically set the target preferential time period and price for users in this area according to the first preferential electricity price information and the second preferential electricity price information.
[0040] In specific implementation, the above-mentioned electricity price output unit 15 can output the final user electricity price information according to at least one of the user electricity price information generated by the first electricity price unit, the retailer electricity price information obtained by the second electricity price unit, the user-configured electricity price information collected by the third electricity price unit, and the specified user preferential electricity price information generated by the fourth electricity price unit. Specifically, for example, when the user is a specified preferential user and the user has configured time-of-use electricity prices, the time-of-use electricity prices of the user electricity price information generated by the first electricity price unit or the retailer electricity price information obtained by the second electricity price unit can be modified according to the user-configured time-of-use electricity price information and the specified user preferential electricity price information to better meet the user's needs; another example is that when the user is a specified preferential user and the user has not configured time-of-use electricity prices, it can also be to only modify the time-of-use electricity prices of the user electricity price information generated by the first electricity price unit or the retailer electricity price information obtained by the second electricity price unit according to the specified user preferential electricity price information, or when the user is not a specified preferential user but the user has configured time-of-use electricity prices, it can be to only modify the time-of-use electricity prices of the user electricity price information generated by the first electricity price unit or the retailer electricity price information obtained by the second electricity price unit according to the user-configured electricity price information, etc. The electricity price output unit sends the final user electricity price information to the policy generation module 6.
[0041] In summary, the above electricity price acquisition module provides a channel for acquiring multi-dimensional electricity price information. By docking with each platform, electricity price information can be acquired in real time and accurately. At the same time, the electricity price information can be corrected based on the actual needs of users, and thus an accurate power consumption scheduling strategy can be provided for users.
[0042] In specific implementation, the above site information acquisition module 2 acquires the real-time device information of the photovoltaic energy storage device. Among them, the real-time device information may include at least one of the real-time SOC value, real-time power generation information, real-time load information, and real-time temperature of the photovoltaic energy storage device. This real-time device information is used for subsequent generation of power consumption strategies to improve the accuracy of power consumption scheduling strategies.
[0043] In specific implementation, when the power generation prediction module uses the power generation prediction model to predict the power generation prediction information of the photovoltaic energy storage device, or when the load prediction module uses the load prediction model to predict the load prediction information, meteorological data is needed for prediction. Therefore, in one embodiment, the power consumption scheduling strategy generation system of the photovoltaic energy storage device may further include: a meteorological actual measurement collector and a meteorological prediction collector; the meteorological actual measurement collector and the meteorological prediction collector are respectively connected to the power generation prediction module and the load prediction module; Among them, the meteorological actual measurement collector is used to collect the meteorological actual measurement data of the photovoltaic energy storage device; The meteorological prediction collector is used to collect the meteorological forecast data of the photovoltaic energy storage device.
[0044] In specific implementation, the meteorological actual measurement collector can regularly collect the meteorological actual measurement data of the location where the photovoltaic energy storage device is located (the longitude and latitude of the photovoltaic energy storage device's station yard); the meteorological prediction collector is used to obtain the meteorological forecast data of the location where the photovoltaic energy storage device is located from each meteorological forecast platform. Among them, the meteorological actual measurement data and the meteorological forecast data include but are not limited to irradiance information, temperature, cloud cover, wind speed, etc.

As Figure 3 shown, the power generation prediction module 3 may include: an irradiance optimizer 31, a first feature extraction unit 32, a power generation prediction model group 33, and a first result output unit 34; Among them, the irradiance optimizer 31 is used to optimize the meteorological forecast data for a future specified time period collected by the meteorological prediction collector by using the historical meteorological actual measurement data collected by the meteorological actual measurement collector and the historical meteorological forecast data collected by the meteorological prediction collector, so as to obtain the optimized meteorological forecast data; The first feature extraction unit 32 is used to extract the first feature data of the optimized meteorological forecast data; The power generation prediction model group 33 is used to predict the power generation prediction information of the photovoltaic energy storage device in a future specified time period according to the first feature data; The first result output unit 34 is used to process the power generation prediction information of the photovoltaic energy storage device in a specified future time period predicted by the power generation prediction model group, and generate the final power generation prediction information of the photovoltaic energy storage device.
[0046] In one embodiment, the above-mentioned power generation prediction model group 33 may include multiple power generation prediction models 331-33N with different structures, and the structure of each power generation prediction model is any one of a deep learning model, a machine learning model, and a large model; Each power generation prediction model outputs the power generation prediction information of the photovoltaic energy storage device in a specified future time period predicted by itself according to the first feature data.
[0047] In specific implementation, during the prediction process of the power generation information of the photovoltaic energy storage device, the irradiance information in the meteorological data is one of the most important factors affecting the power generation of photovoltaic power generation. The photovoltaic cell module needs sunlight irradiation to be converted into electric energy.
