Description

Technical Field

[0001] This invention belongs to the field of scheduling management technology, and in particular relates to a comprehensive scheduling method and scheduling platform for new energy power plants. Background Technology

[0002] With the large-scale grid connection of new energy power plants, the stability of power grid operation has been greatly challenged. Therefore, how to manage the dispatch of new energy power plants to ensure the stability and reliability of power grid operation has become an urgent technical problem to be solved.

[0003] To address the aforementioned issues, the invention patent application CN202610056521.1, "A Digital Twin Optimization Scheduling Method and System for Power Grids Oriented to Renewable Energy Consumption," establishes the characteristics of renewable energy output fluctuations across multiple time scales. It utilizes the results of multi-stakeholder game theory to establish a scheduling strategy and performs optimized scheduling management based on this strategy. This solves the technical problems of existing technologies, such as the difficulty in accurately addressing the uncertainty of renewable energy output and the lack of a multi-stakeholder interest coordination mechanism, leading to low renewable energy consumption efficiency and high grid operation safety risks. It achieves the technical effect of optimizing renewable energy consumption scheduling, improving renewable energy consumption efficiency and grid operation safety. However, the following technical problems remain: In the process of scheduling and managing new energy power stations, under certain weather conditions, multiple new energy power stations may have energy storage regulation needs at the same time. Therefore, when different new energy power stations have energy storage regulation needs at the same time, the grid-connected power of the new energy power stations may be severely affected due to insufficient energy storage space. Therefore, how to determine the regulation and control method of energy storage devices based on the degree of overlap of the energy storage regulation needs of different new energy power stations, so as to achieve coordinated control and management of energy storage space under different weather conditions, and improve the reliability of consumption and processing while reducing the frequency of energy storage device regulation, has become an urgent technical problem to be solved.

[0004] Specifically, this application provides a comprehensive scheduling method and scheduling platform for new energy power plants. Summary of the Invention

[0005] To achieve the objectives of this invention, the following technical solution is adopted: Specifically, this application provides a comprehensive scheduling method for new energy power plants, which includes: S1 uses the operation data of the new energy power station to determine the consumption demand period of the new energy power station under different weather types. Based on the degree of overlap between the consumption demand period and the consumption demand period of each new energy power station, it determines the coordinated regulation weather type and other weather types among the weather types. S2 determines the output regulation demand type of the new energy power station based on the coordinated weather type and the degree of deviation of the power generation of the new energy power station from other weather types under the coordinated weather type; S3 determines the coordinated regulation strategy of energy storage devices in the coordinated regulation weather type based on the power generation of new energy power stations with different output regulation demand types under the coordinated regulation weather type. S4 determines the control weather type in the coordinated weather type using the coordinated regulation strategy, and determines the regulation management method of the energy storage device by combining the threshold of the energy storage device in the coordinated weather type with the degree of adaptation of the regulation demand space of the energy storage device in other weather types.

[0006] The beneficial effects of this invention are as follows: Based on the degree of overlap between the consumption demand period and the consumption demand period of each new energy power station, the degree of overlap between the consumption demand periods of new energy power stations and the degree of demand for energy storage regulation are determined. Then, by using the degree of demand for energy storage regulation, the coordinated regulation weather type in the weather type is determined, thereby ensuring both the flexibility and reliability of energy storage regulation.

[0007] Based on the proportion of controlled weather types in the coordinated regulated weather types and the degree of compatibility between the thresholds of different coordinated regulated weather types and the regulation demand space of other weather types, the regulation management method of energy storage devices is determined. That is, the regulation management method of energy storage devices excluding controlled weather types realizes the coordinated control and processing of energy storage space in different weather types, thereby further improving the stability and reliability of the operation of different new energy power stations.

[0008] Furthermore, the operational data of the new energy power station includes the operating period of the new energy power station and the amount of electricity generated during the operating period.

[0009] Furthermore, the consumption demand period under the aforementioned weather type is determined based on the period during which the power generation of the new energy power station needs to be consumed using energy storage devices under the aforementioned weather type.

[0010] Furthermore, the method for determining the coordinated weather type in the aforementioned weather types is as follows: Based on the degree of overlap between the consumption demand period and the consumption demand period of each new energy power station, the new energy power stations that belong to the consumption demand period in different dates under the weather type are identified, and the new energy power stations that belong to the consumption demand period in the time period are selected as the matching consumption demand stations. The weight value of the absorption demand in the time period is determined based on the number of sites that match the absorption demand in the time period. The coordinated weather type is determined by the weight value of the consumption demand in each time period on different dates.

[0011] Furthermore, the method for determining the regulation and management method of the energy storage device is as follows: The control ratio is determined based on the proportion of the controlled weather type among the coordinated regulated weather types; The regulation demand space for the other weather types is constructed by the endpoints of the energy storage space of the energy storage device that meets the requirement that the proportion of days with a ratio of 0 to other weather types of absorption is above a preset absorption ratio threshold. By utilizing the control ratio and the degree of adaptation between the thresholds of different coordinated weather types and the adjustment demand space of other weather types, the regulation and management method of the energy storage device is determined.

[0012] Secondly, the present invention provides a scheduling platform that employs the aforementioned comprehensive scheduling method for new energy power plants, specifically including: The weather type classification module is responsible for determining the coordinated weather type and other weather types among the weather types; The coordinated regulation module is responsible for determining the coordinated regulation strategy of energy storage devices in the coordinated regulation weather type; The regulation and management module is responsible for determining the regulation and management methods for the energy storage device.

The objects and other advantages of the invention are realized and obtained through the structures particularly pointed out in the description and the drawings.

[0014] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0015] The above and other features and advantages of the present invention will become more apparent from a detailed description of exemplary embodiments thereof with reference to the accompanying drawings.

Detailed Implementation

[0017] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0018] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0019] Example 1 To solve the above problems, according to one aspect of the present invention, such as Figure 1 As shown, a comprehensive scheduling method for new energy power plants is provided, specifically including: S1 uses the operation data of the new energy power station to determine the consumption demand period of the new energy power station under different weather types. Based on the degree of overlap between the consumption demand period and the consumption demand period of each new energy power station, it determines the coordinated regulation weather type and other weather types among the weather types. Furthermore, the operational data of the new energy power station includes the operating period of the new energy power station and the amount of electricity generated during the operating period.

[0020] It should be noted that the consumption demand period under the aforementioned weather type is determined based on the period during which the power generation of the new energy power station needs to be consumed using energy storage devices under the aforementioned weather type.

[0021] It is understandable that, such as Figure 2 As shown, the method for determining the coordinated weather type in the aforementioned weather types is as follows: In this embodiment, the degree of overlap between the consumption demand period and the consumption demand period of each new energy power station is determined based on the degree of overlap. The degree of demand for energy storage regulation is then used to determine the coordinated regulation weather type in the weather type, thereby ensuring both the flexibility and reliability of energy storage regulation.

[0022] The term "consumption demand period" refers to the period during which the power generated by new energy power plants needs to be consumed using energy storage devices; the term "overlap" refers to the degree of time overlap between the consumption demand periods of different new energy power plants; and the term "demand for energy storage regulation" refers to the urgency of needing energy storage for consumption under a certain weather type.

[0023] For example, if the demand periods for energy storage at multiple renewable energy power plants highly overlap under a certain weather type, it indicates that the demand for energy storage regulation is relatively high under this weather type, and thus it is identified as a coordinated regulation weather type.

[0024] By assessing the degree of overlap between demand periods and energy storage periods, and determining the weather types for coordinated regulation, energy storage regulation resources are focused on the weather types with the most urgent demand, thereby ensuring both regulation flexibility and regulation reliability.

[0025] S11. Based on the degree of overlap between the consumption demand period and the consumption demand period of each new energy power station, determine the new energy power stations that belong to the consumption demand period in different dates of the weather type, and use the new energy power stations that belong to the consumption demand period in the time period as the matching consumption demand stations. The term "matching demand-demand power station" refers to a new energy power station that is in a demand-demand period on a certain date during a certain weather type.

[0026] If, under a certain weather condition, a certain date and time period, the power generation of multiple renewable energy power plants needs to be absorbed by energy storage, then these power plants are the matching absorption demand power plants for that time period.

[0027] By identifying and matching energy storage sites with demand, the sites that need energy storage in each time period are quantified into a specific set of sites, providing basic data for the subsequent calculation of the weight value of energy storage demand.

[0028] S12, determine the absorption demand weight value in the time period based on the number of matching absorption demand sites in the time period; Specifically, the demand weight value in the time period is determined based on the proportion of the number of power plants matching the demand in the target power grid area.

[0029] It is understood that the target power grid area is the power grid area for scheduling and management of new energy power plants.

[0030] The absorption demand weight value = number of power stations matching absorption demand in a certain period / total number of new energy power stations in the target power grid area, reflecting the coverage of power stations that need energy storage absorption in that period. Assuming that there are 8 power stations in the absorption demand period in a certain period, and there are a total of 20 power stations in the target power grid area, then the absorption demand weight value is 8 / 20=0.40.

[0031] By matching the proportion of power plants with the demand for power consumption to calculate the weight value of the demand, the degree of demand for power consumption in each time period is quantified into a comparable weight value, providing a basis for determining the weather type for subsequent coordinated regulation.

[0032] S13 determines the coordinated weather type among the weather types by using the weight values ​​of the consumption demand in different time periods on different dates.

[0033] Specifically, the coordinated adjustment weather type is determined by the weighting values ​​of the consumption demand in different time periods on different dates, including: The consumption demand value for the given date is determined by summing the consumption demand weight values ​​for each time period within the given date. If the average value of the absorption demand for the weather type on different dates meets the requirements, that is, if the average value of the absorption demand on different dates is large, then the need for absorption processing is high. Therefore, the weather type is determined to be a coordinated regulation weather type.

[0034] The consumption demand value for a given date is the sum of the consumption demand weights for all time periods within that date. "Meeting the requirements" means that the average consumption demand value is greater than a preset consumption demand value threshold, indicating a high consumption demand.

[0035] If the average demand value of a certain weather type on different dates exceeds the preset demand value threshold, it indicates that the demand for energy storage is high under this weather type. In this case, it is identified as a coordinated regulation weather type. The average demand value is used to determine whether the weather type belongs to the coordinated regulation weather type. When the demand is high, the weather type is included in the coordinated regulation scope for key management, thereby ensuring the reliability of energy storage regulation and processing.

[0036] Specifically, if the weather type is not a coordinated weather type, i.e., it is another weather type, then the energy storage device is needed for discharge processing only when the power supply in the target power grid area is insufficient to meet the power load demand.

[0037] Specifically, if the weather type is a coordinated weather type, then as long as the remaining space of the energy storage device reaches a certain range, the energy storage device will be used as the scheduling target for discharge processing, thereby ensuring that the energy storage device is maintained within a certain capacity range and ensuring the reliability of the absorption and processing.

[0038] This embodiment realizes a complete process from identifying energy storage sites that match the demand for energy consumption to calculating the weight value of the demand for energy consumption and determining the weather type for coordinated regulation. Its core value is reflected in two aspects: First, by matching the proportion of energy storage sites that match the demand for energy consumption, the degree of demand for energy consumption in each time period is quantified, providing a quantitative basis for the selection of weather types for coordinated regulation. Second, by judging whether the weather type belongs to the weather type for coordinated regulation by the average value of the demand for energy consumption, different levels of energy storage dispatch strategies are adopted when the demand for energy consumption is different, thereby achieving precise matching between dispatch strategies and demand for energy consumption.

[0039] A target power grid area includes 20 renewable energy power stations, and the weather types are divided into 8 categories: W1-W8. Dates with similar solar irradiance and wind speed are grouped into the same weather type. W1 will be used as an example for explanation.

[0040] The number of sites matching and absorbing the demand for W1 in different dates (5 days in total) and for different time periods (each day is divided into 4 time periods) is as follows: Date D1: Time periods T1 has 12, T2 has 15, T3 has 8, and T4 has 10. Date D2: Time periods T1 has 14, T2 has 16, T3 has 9, and T4 has 11; Date D3: Time periods T1 has 11, T2 has 13, T3 has 7, and T4 has 9; Date D4: Time periods T1 has 13, T2 has 14, T3 has 10, and T4 has 12; Date D5: Time periods T1 has 12, T2 has 15, T3 has 8, and T4 has 10; The weight value of the demand for each time period = the number of matching stations / 20.

[0041] Step S11: The matching and consumption demand of the stations for each time period is as described above.

[0042] Step S12: Weighting of demand for each time period: D1: T1=0.60, T2=0.75, T3=0.40, T4=0.50; D2: T1=0.70, T2=0.80, T3=0.45, T4=0.55; D3: T1=0.55, T2=0.65, T3=0.35, T4=0.45; D4: T1=0.65, T2=0.70, T3=0.50, T4=0.60; D5: T1=0.60, T2=0.75, T3=0.40, T4=0.50; Step S13: The consumption demand value for each date = the sum of the consumption demand weight values ​​for each time period.

[0043] D1=0.60+0.75+0.40+0.50=2.25; D2=0.70+0.80+0.45+0.55=2.50; D3=0.55+0.65+0.35+0.45=2.00; D4=0.65+0.70+0.50+0.60=2.45; D5=0.60+0.75+0.40+0.50=2.25; Average demand value = (2.25 + 2.50 + 2.00 + 2.45 + 2.25) / 5 = 11.45 / 5 = 2.29.

[0044] Determine if the mean value of 2.29 meets the requirement (i.e., it is greater than the preset threshold value of 2.00 for the absorption demand): 2.29 is greater than 2.00, so W3 is determined to be a coordinated weather type.

[0045] S2 determines the output regulation demand type of the new energy power station based on the coordinated weather type and the degree of deviation of the power generation of the new energy power station from other weather types under the coordinated weather type; Specifically, such as Figure 3 As shown, the method for determining the output regulation demand type of the new energy power station is as follows: In this embodiment, based on the coordinated weather type and the degree of deviation between the power generation of new energy power plants in the coordinated weather type and the power generation of other weather types, the demand for output adjustment of different new energy power plants under the current coordinated weather type is determined. This allows for the determination of different output adjustment demand types for new energy power plants under the current coordinated weather type, thus laying the foundation for determining the coordinated adjustment strategy of energy storage devices in the coordinated weather type based on the output adjustment demand type.

[0046] The output adjustment demand type refers to the adjustment demand classification type determined according to the degree of power generation deviation of new energy power plants under coordinated weather conditions, including Class I adjustment demand type and Class II adjustment demand type, with Class I adjustment demand type being greater than Class II adjustment demand type; the output adjustment demand degree refers to the urgency of a new energy power plant needing to adjust its output under coordinated weather conditions.

[0047] If a certain new energy power plant has a high proportion of power generation under coordinated weather conditions, it indicates that the energy storage regulation control under coordinated weather conditions has a high degree of influence on its normal grid connection and absorption. Therefore, its output regulation demand is high and belongs to a type of regulation demand. The output regulation demand is assessed by the degree of power generation deviation and the output regulation demand type is determined accordingly, providing a graded basis for the determination of subsequent coordinated regulation strategies for energy storage devices.

[0048] S21 Based on the aforementioned coordinated weather types, determine the proportion of coordinated weather types in the total number of weather types, and use it as the coordinated proportion. The proportion of coordinated regulation = number of coordinated weather types / total number of weather types, reflecting the coverage of coordinated weather types among all weather types.

[0049] Assuming that two of the four weather types are coordinated weather types, the coordinated regulation ratio is 2 / 4 = 0.50. By calculating the coordinated regulation ratio, the coverage of coordinated weather types is quantified, providing a basis for the subsequent classification and determination of the type of power output regulation demand.

[0050] It is understood that if the proportion of coordinated regulation is above the preset weather type proportion threshold in the above steps, the output regulation demand type of the new energy power station is determined to be a type of regulation demand. The preset weather type proportion threshold refers to the critical value for judging whether the proportion of coordinated regulation is high. When the proportion is high, it indicates that the coordinated regulation weather types cover a wide range, and all stations need to pay close attention to them and uniformly determine them as a type of regulation demand.

[0051] If the proportion of coordinated regulation exceeds the preset threshold for the proportion of weather types, then the output regulation demand type of all new energy power plants will be determined as a type of regulation demand.

[0052] It should also be noted that if the proportion of coordinated adjustment is not above the preset weather type proportion threshold, proceed to step S22; S22, determine the proportion of power generation of the new energy power station in the coordinated weather type based on the degree of deviation between the power generation of the new energy power station in the coordinated weather type and the power generation of other weather types; The power generation ratio = power generation of the renewable energy power plant in the coordinated weather type / total power generation of the power plant in all weather types, reflecting the degree of power generation contribution of the power plant to the coordinated weather type.

[0053] If a certain power station generates 70% of its total power generation under the coordinated weather conditions, then the power generation ratio is 0.70.

[0054] By assessing the contribution of the power generation ratio to the power generation of the power plants under the coordinated regulation of weather types, a quantitative basis is provided for the subsequent detailed determination of the power output regulation demand types.

[0055] S23. Based on the coordinated regulation ratio and the power generation ratio of the new energy power station in the coordinated regulation weather type, determine the output regulation demand type of the new energy power station.

[0056] It is understood that, based on the aforementioned coordinated regulation ratio and the power generation ratio of the new energy power plants in the coordinated regulation weather type, the output regulation demand type of the new energy power plants is determined, specifically including: Case 1: If the power generation ratio of the new energy power station in the coordinated weather type is above the preset power generation ratio threshold, then the output regulation demand type of the new energy power station is determined to be a type of regulation demand. The preset power generation ratio threshold refers to the critical value for judging whether the power generation ratio is high. When the ratio is high, it indicates that the energy storage regulation control under the coordinated weather type has a high degree of impact on its normal grid connection and absorption, and its output regulation demand is high, which is directly determined as a type of regulation demand.

[0057] If the power generation ratio of a certain power station exceeds the preset power generation ratio threshold, it is identified as a type of demand regulation.

[0058] Scenario 2: If the power generation ratio of the new energy power station in the coordinated regulation weather type is not above the preset power generation ratio threshold, the demand value of the new energy power station is determined by using the coordinated regulation ratio and the power generation ratio of the new energy power station in the coordinated regulation weather type. It is then determined whether the demand value of the new energy power station is greater than the preset impact threshold. If yes, the output regulation demand type of the new energy power station is determined to be a type I regulation demand type. If no, the output regulation demand type of the new energy power station is determined to be a type II regulation demand type.

[0059] The demand value is calculated as follows: Demand Value = Coordinated Regulation Ratio + Power Generation Ratio. The higher the coordinated regulation ratio and the higher the power generation ratio, the greater the impact on grid connection reliability, and thus the higher the demand value. The preset impact threshold refers to the critical value for determining whether the demand value is high.

[0060] If a power plant's power generation ratio is not high, but the sum of its coordinated regulation ratio and power generation ratio exceeds a preset impact threshold, it is identified as a type of regulation demand. If the sum does not exceed the threshold, it is identified as a type of regulation demand.

[0061] When the power generation ratio is not high, further assessment of demand value is significant because when the power generation ratio is in the transition range, the impact of the coordinated regulation ratio and the power generation ratio on the grid-connected power of new energy power plants can be comprehensively assessed, and then dynamic selection can be made between the two types of demand, thereby achieving a precise match between the determination of demand type and the degree of demand regulation.

[0062] Continuing with the calculation results of S1, among the four weather types, W3 and W4 are synergistic weather types, while W1 and W2 are other weather types. This will be illustrated using three renewable energy power stations, S1, S2, and S3, as examples.

[0063] Step S21: Co-regulation ratio = 2 / 4 = 0.50.

[0064] Determine whether the proportion of coordinated regulation (0.50) is above the preset weather type proportion threshold (0.60): If 0.50 is not above 0.60, proceed to S22.

[0065] S22 Step: The proportion of power generation by each station under coordinated weather conditions: S1 generates 800 MWh of electricity in the coordinated weather type, and the total electricity generation is 1200 MWh. The electricity generation ratio is 800 / 1200 = 0.667.

[0066] Step S23: S1: The power generation ratio of 0.667 is above the preset power generation ratio threshold of 0.60, which belongs to Case 1 and is determined as a type of demand regulation.

[0067] S3 determines the coordinated regulation strategy of energy storage devices in the coordinated regulation weather type based on the power generation of new energy power stations with different output regulation demand types under the coordinated regulation weather type. It should be noted that the method for determining the coordinated regulation strategy of energy storage devices in the aforementioned coordinated weather type is as follows: In this embodiment, based on the different power output regulation demand types of new energy power plants and the power generation of the new energy power plants, a coordinated regulation strategy for energy storage devices in coordinated weather types is determined. This realizes a comprehensive assessment of the power output regulation demand of new energy power plants from the perspective of existing coordinated weather types, and uses the power output regulation demand of new energy power plants to determine the coordinated regulation strategy for energy storage devices in coordinated weather types. This reduces the operating frequency of energy storage devices while ensuring reliable absorption of power from different new energy power plants.

[0068] The coordinated regulation strategy refers to the decision rules for determining which coordinated weather types are used as the control weather types and what preset strategies are used to determine the threshold of the energy storage device; the threshold refers to the maximum endpoint threshold of the interval in which the energy storage device is used as the scheduling target for discharge processing.

[0069] If multiple renewable energy power plants have high regulation needs and a large proportion of power generation, then all weather types requiring coordinated regulation should be used as the control weather type and the threshold should be determined using the first preset strategy.

[0070] By adjusting the demand weighting coefficient and the power generation ratio, the energy storage regulation demand is assessed, and a coordinated regulation strategy is determined accordingly. This reduces the frequency of operation of energy storage devices while ensuring reliable absorption and processing at different sites.

[0071] S31 determines the adjustment demand weighting coefficient of the new energy power station based on the different types of output adjustment demand of the new energy power station; The adjustment demand weight coefficient is determined based on the preset weight value corresponding to the type of output adjustment demand. Type I adjustment demand corresponds to a higher weight value, and type II adjustment demand corresponds to a lower weight value.

[0072] Assuming that the weight value for type I adjustment demand is 0.8 and that for type II it is 0.4, then the adjustment demand weight coefficient for a certain station that is classified as type I is 0.8.

[0073] By mapping the adjustment demand type to the adjustment demand weight coefficient, the adjustment demand of the power station is quantified into comparable weight values.

[0074] It is understood that the above steps include the following: Scenario 1: Based on the adjustment demand weight coefficients of different new energy power stations, determine the sum of the adjustment demand weight coefficients of different new energy power stations, and use it as the adjustment demand value. If the adjustment demand value does not meet the requirements, that is, when it is greater than a certain threshold, then determine the coordinated adjustment strategy of the energy storage device in the coordinated adjustment weather type as treating all coordinated weather types as control weather types. Under the control weather type, the first preset strategy is used to determine the threshold, that is, the energy storage device is used as the scheduling target, and the maximum endpoint threshold of the interval in which the energy storage device is used for discharge processing is determined.

[0075] The regulation demand value is the sum of the regulation demand weighting coefficients of all new energy power plants. "Not meeting the requirements" means the regulation demand value is greater than the preset regulation demand threshold, i.e., the regulation demand is high. When the regulation demand is high, all coordinated regulation weather types are used as the control weather type, and the threshold is determined using the first preset strategy.

[0076] The first preset strategy is to use the maximum value of the energy storage space when the proportion of the number of time periods with insufficient energy storage space is less than a preset proportion threshold when multiple new energy power stations that need to be absorbed overlap under the controlled weather type.

[0077] If the adjustment demand value exceeds the preset adjustment demand threshold, it indicates that the overall adjustment demand is high. In this case, all coordinated adjustment weather types are treated as control weather types, and the first preset strategy is used to determine the threshold.

[0078] When the regulation demand is high, a full-volume control strategy is adopted. When the overall regulation demand is high, the energy storage device’s absorption capacity is ensured by fully controlling the weather type and the first preset strategy, thereby ensuring reliable absorption.

[0079] Scenario 2: If the regulation demand value meets the requirements, based on the regulation demand weight coefficients of different new energy power plants, determine whether there are new energy power plants whose regulation demand weight coefficients are greater than the preset weight coefficient threshold. If yes, proceed to step S32. If no, use the power generation of new energy power plants of different output regulation demand types under the coordinated regulation weather type, and take the proportion of the power generation of a type of new energy power plant under the coordinated regulation weather type as the coordinated regulation demand value of the coordinated regulation weather type. The coordinated regulation weather type with a coordinated regulation demand value above the preset demand value is taken as the control weather type. Under the control weather type, the first preset strategy is used to determine the threshold. If it does not belong to the control weather type, the second preset strategy is used to determine the threshold.

[0080] The term "meeting the requirements" means that the regulation demand value is not greater than the preset regulation demand threshold, i.e., the regulation demand is not high. When the regulation demand is not high, it is handled separately based on whether there are high-weight power plants. The coordinated regulation demand value = power generation of power plants of one type of regulation demand / total power generation of all power plants under the coordinated regulation weather type. The preset demand value refers to the critical value for judging whether the coordinated regulation demand value is high. The second preset strategy is to use the maximum value of the energy storage space without insufficient energy storage space during the overlapping period of multiple new energy power plants that need to be absorbed under the controlled weather type as the threshold.

[0081] Assuming that the adjustment demand value does not exceed the preset adjustment demand threshold and there are no high-weight stations, the control weather type is selected based on the coordinated adjustment demand value. The first preset strategy is used for the higher demand value, and the second preset strategy is used for the lower demand value.

[0082] When the regulation demand is not high, the strategy is determined by classifying the existence of high-weight stations and the value of coordinated regulation demand. The significance is that when the overall regulation demand is not high, the strategy is dynamically selected between the first and second preset strategies through refined analysis, thereby achieving a precise match between the coordinated regulation strategy and the regulation demand.

[0083] S32, Based on the power generation of the new energy power station, determine the proportion of the power generation of the new energy power station, and use it as the proportion of the power generation of the new energy power station; The power generation share = power generation of a certain new energy power station / total power generation of all new energy power stations, reflecting the degree of contribution of the power station to the overall power generation.

[0084] If a certain power plant generates 800 MWh and the total power generation of all power plants is 3700 MWh, then the power generation ratio is 800 / 3700 ​​= 0.216.

[0085] Assessing the power generation contribution of power plants by evaluating their power generation share provides a quantitative basis for refining and determining subsequent coordinated regulation strategies.

[0086] S33, using the regulation demand weighting coefficients and power generation ratios of different new energy power stations, determine the coordinated regulation strategy of energy storage devices in the coordinated regulation weather type.

[0087] It is understandable that, based on the regulation demand weighting coefficients and power generation ratios of different new energy power plants, the coordinated regulation strategy for energy storage devices in the aforementioned coordinated weather types is determined, specifically including: S331, new energy power plants with a demand adjustment weight coefficient greater than a preset weight coefficient threshold are designated as demand power plants. It is determined whether the sum of the power generation ratios of the demand power plants is above a preset ratio threshold. If so, the coordinated adjustment strategy of the energy storage device in the coordinated weather type is determined to treat all coordinated weather types as control weather types. Under the control weather type, the first preset strategy is used to determine the threshold. If not, proceed to step S332. The term "demand-generating stations" refers to stations whose demand weighting coefficient exceeds a preset weighting coefficient threshold. The preset percentage threshold is a critical value used to determine whether the power generation percentage of demand-generating stations is high. When the percentage is high, it indicates that high-demand stations contribute significantly to power generation, and a full-capacity control strategy is adopted.

[0088] If the power generation ratio of all power plants in the coordinated weather type exceeds a preset threshold, then all coordinated weather types will be used as the control weather type and the first preset strategy will be adopted.

[0089] By assessing the proportion of power generation from demand-driven power plants and further evaluating the situation, a full-capacity control strategy is adopted when the power generation contribution from high-demand power plants is significant, in order to ensure the absorption capacity.

[0090] S332, using the adjustment demand weighting coefficients and power generation ratios of different new energy power plants, determine the comprehensive demand value. Determine whether the comprehensive demand value is greater than the preset output demand threshold. If so, determine the coordinated adjustment strategy for energy storage devices in the coordinated adjustment weather type as treating all coordinated weather types as control weather types. Under the control weather type, use the first preset strategy to determine the threshold. If not, use the power generation of new energy power plants with different output adjustment demand types under the coordinated adjustment weather type, and determine the coordinated adjustment demand value of the coordinated adjustment weather type by taking the power generation ratio of a type of adjustment demand new energy power plant under the coordinated adjustment weather type. Take the coordinated adjustment weather type with a coordinated adjustment demand value above the second influence preset value as the weather type that needs to be jointly adjusted and analyzed, and use the first preset strategy to determine the threshold under the control weather type. If it does not belong to the control weather type, use the second preset strategy to determine the threshold.

[0091] The comprehensive demand value is calculated as follows: the comprehensive demand value is the sum of the regulation demand weighting coefficients of different new energy power plants multiplied by their power generation ratios. The preset output demand threshold refers to the critical value used to determine whether the comprehensive demand value is high. If the second impact preset value is greater than the demand preset value, stricter screening conditions are adopted. When the comprehensive demand value is high, a full-scale control strategy is adopted; when it is low, the joint regulation weather type is selected based on the coordinated regulation demand value and the second impact preset value.

[0092] If the calculated comprehensive demand value is greater than the preset output demand threshold, a full-scale control strategy is adopted; if it is not greater, the demand value is adjusted according to the coordinated adjustment and the preset value of the second influence.

[0093] The coordinated regulation strategy is ultimately determined by the comprehensive demand value. When the proportion of power generation from demanding power plants is not high, the strategy is dynamically selected between full control and joint regulation analysis based on comprehensive assessment, thereby achieving a precise match between the coordinated regulation strategy and the regulation demand.

[0094] This embodiment realizes a complete process from determining the regulation demand weighting coefficient to calculating the power generation ratio and then determining the coordinated regulation strategy. Its core value is reflected in three aspects: First, it assesses the overall regulation demand by adjusting the demand value and adopts a full control strategy when the demand is high; second, it adopts a full control strategy when the power generation ratio of demand-driven plants is high and further assessed, and adopts a full control strategy when the power generation contribution of high-demand plants is large; third, it dynamically selects the strategy level when the regulation demand is different by making multi-level judgments on the comprehensive demand value and the coordinated regulation demand value, thereby achieving a precise match between the coordinated regulation strategy and the regulation demand.

[0095] Continuing the calculation results from S2, the three renewable energy power stations are classified as S1 (Category I), S2 (Category II), and S3 (Category II). The demand adjustment weight coefficients are mapped as follows: Category I = 0.8, Category II = 0.4. Therefore, S1 = 0.8, S2 = 0.4, and S3 = 0.4.

[0096] The daily average power generation of each station under the same weather conditions is as follows: S1 = 800 MWh, S2 = 400 MWh, S3 = 600 MWh, and the total power generation is 1800 MWh. The power generation percentages are: S1 = 0.444, S2 = 0.222, and S3 = 0.333.

[0097] Step S31: Adjust the demand value = 0.8 + 0.4 + 0.4 = 1.60.

[0098] Determine whether the adjustment demand value of 1.60 does not meet the requirements (i.e., it is greater than the preset adjustment demand threshold of 1.50): 1.60 is greater than 1.50, which does not meet the requirements (the adjustment demand is too high), belonging to case 1.

[0099] The coordinated regulation strategy is determined by treating all coordinated regulation weather types (W3 and W4) as control weather types, and using the first preset strategy to determine the threshold under the control weather type.

[0100] The first preset strategy is to use the maximum value of the energy storage space when the proportion of the number of times when multiple new energy power stations that need to be absorbed overlaps under the controlled weather type is less than the preset proportion threshold.

[0101] Statistics show that during the overlapping periods of energy consumption at multiple power stations under W3, the proportion of periods with insufficient energy storage space is 0.15% (less than the preset threshold of 0.20%), and the maximum energy storage space under this condition is 80%. Therefore, the threshold for W3 is set at 80%. Similarly, the threshold for W4 is set at 75%.

[0102] S4 determines the control weather type in the coordinated weather type using the coordinated regulation strategy, and determines the regulation management method of the energy storage device by combining the threshold of the energy storage device in the coordinated weather type with the degree of adaptation of the regulation demand space of the energy storage device in other weather types.

[0103] It is understood that the method for determining the regulation and management method of the energy storage device is as follows: In this embodiment, the regulation and management method of the energy storage device is determined based on the proportion of the controlled weather type in the coordinated regulation weather type and the degree of adaptability of the threshold of different coordinated regulation weather types to the regulation demand space of other weather types. That is, the regulation and management method of the energy storage device excluding the controlled weather type realizes the coordinated control processing of the energy storage space between different weather types, thereby further improving the stability and reliability of the operation of different new energy power stations.

[0104] The regulation management method refers to the decision rules for determining the threshold adjustment mode of energy storage devices in coordinated regulated weather types other than the controlling weather type; the regulation demand space refers to the available energy storage space range of energy storage devices under other weather types.

[0105] If the threshold of a certain weather type for coordinated regulation is well-suited to the regulation demand space of other weather types, then no additional regulation and control processing is required.

[0106] By assessing the coordinated control needs of energy storage space under different weather conditions through control ratios and adaptability, and determining the adjustment and management methods accordingly, the stability and reliability of operation of different new energy power stations can be improved.

[0107] S41, determine the control ratio based on the proportion of the controlled weather type among the coordinated regulated weather types; It is understood that if the control ratio is greater than the preset control ratio threshold, the power generation reliability is high. Therefore, it is determined that the regulation and management method of energy storage devices other than the controlled weather type in the coordinated weather regulation is that no regulation and control processing is required.

[0108] The control ratio is calculated as the number of controlled weather types divided by the total number of coordinated weather types. A high control ratio indicates that most coordinated weather types have been brought under control, and no additional management is required for the remaining weather types.

[0109] If the control ratio exceeds the preset control ratio threshold, then no adjustment or control measures need to be taken for weather types other than the controlled weather types.

[0110] When the control ratio is high, an unmanaged strategy is adopted. When most weather types have been controlled, the adjustment needs of the remaining weather types can be covered by the existing control strategy, thereby avoiding unnecessary adjustment.

[0111] S42, construct the regulation demand space for other weather types by using the endpoints of the energy storage space of the energy storage device that meets the requirement that the proportion of days with a consumption ratio of 0 and other weather types is above the preset consumption ratio threshold. The regulation demand space is constructed based on the endpoints of the energy storage space of the energy storage device on days with a higher proportion of energy consumption in other weather types, reflecting the available space range of the energy storage device under other weather types.

[0112] Assuming that the energy storage capacity for days with a higher proportion of energy absorption in other weather types W1 is between 20% and 60%, then the regulation demand capacity of W1 is between 20% and 60%.

[0113] By constructing demand adjustment space based on dates with a higher consumption ratio, the available space of energy storage devices under other weather types is quantified into interval data, providing a basis for subsequent adaptation assessment.

[0114] S43 determines the regulation and management method of the energy storage device by utilizing the control ratio and the degree of adaptation between the threshold of different coordinated weather types and the regulation demand space of other weather types.

[0115] Specifically, in the above steps, the regulation and management method of the energy storage device under other weather types is determined by utilizing the control ratio and the degree of adaptation between the threshold of different coordinated weather types and the regulation demand space of other weather types. This specifically includes: S431 determines other weather types as suitable weather types by comparing the control range of the optimal energy storage device under other weather types with the threshold. The deviation rate between the endpoint corresponding to the adjustment demand space and the threshold of any coordinated adjustment weather type is less than the preset deviation rate threshold. The number of suitable weather types is then determined. If the number of suitable weather types meets the requirements, the adjustment management method for energy storage devices other than the control weather type in the coordinated adjustment weather type is not required. If not, the process proceeds to step S432. The "suitable weather type" refers to a weather type whose deviation rate between the spatial endpoint of the adjustment demand of other weather types and the threshold of a certain coordinated adjustment weather type is less than a preset deviation rate threshold. "Meets the requirements" means that the number of suitable weather types exceeds a preset threshold, i.e., a large number. When there are many suitable weather types, it indicates that other weather types are well-suited to the threshold of the coordinated adjustment weather type, and no additional control is required.

[0116] If the deviation rate between the spatial endpoints of the regulation demand for most other weather types and the threshold of the coordinated regulation weather type is small, then no regulation and control measures are required.

[0117] The degree of adaptation is assessed by the number of weather types that can be matched. When the degree of adaptation is high, no additional control is required. When the degree of adaptation is low, further analysis and adjustment methods are needed.

[0118] S432, using the deviation rate between the endpoints corresponding to the adjustment demand space under different weather types and the threshold, and the control ratio, the adjustment adaptation coefficient of the new energy power station is determined. It is then determined whether the adjustment adaptation coefficient of the new energy power station is greater than a preset adaptation coefficient threshold. If not, the adjustment management method for energy storage devices in the coordinated adjustment weather types (excluding the control weather type) is to use weather types where the deviation rate between the threshold of the weather type and the maximum value of the endpoints corresponding to the adjustment demand space of other weather types is less than a preset deviation rate value as the adaptable weather type. Whenever an adaptable weather type exists, the adjustment of the adaptable weather type is adopted. The maximum value of the endpoints of the demand space and the minimum value of the threshold in the weather type are used as control targets. The control targets are used as thresholds according to a preset time period. In other cases, the original threshold is still used for control processing. The regulation and management method of the weather type is determined. If so, the regulation and management method of the energy storage device in the coordinated regulation weather type, excluding the control weather type, is to take other weather types whose threshold of the weather type and the endpoints corresponding to the regulation demand space of other weather types have a deviation rate of less than a preset deviation rate as the adaptive weather types. The regulation and management method of the weather type is determined according to the number of adaptive weather types of the weather type.

[0119] The adjustment adaptation coefficient is calculated as follows: Adjustment adaptation coefficient = (1 - mean deviation rate) × control ratio. If the preset deviation rate value is greater than a preset deviation rate threshold, a more lenient adaptation condition is adopted. When the adjustment adaptation coefficient is not greater than the preset adaptation coefficient threshold, a conditional control target strategy is adopted; when it is greater, it is further determined based on the number of weather types to be adapted.

[0120] If the calculated adaptation coefficient is not greater than the preset adaptation coefficient threshold, it indicates that the degree of adaptation is not high. In this case, a conditional control target strategy is adopted, and the control target is used as the threshold only when there is an adaptable weather type, according to the preset time period.

[0121] The adjustment management method is further refined by adjusting the adaptation coefficient. When the degree of adaptation is different, the adjustment method is dynamically adjusted according to the comprehensive evaluation of the adjustment adaptation coefficient and the control ratio, so as to achieve a precise match between the adjustment management method and the degree of adaptation.

[0122] Furthermore, based on the number of compatible weather types, the adjustment and management method for the weather type is determined, specifically including: If the number of adaptable weather types for the weather type is above the preset threshold for the number of adaptable weather types, then the maximum value of the endpoint of the adjustment demand space of the adaptable weather type and the minimum value of the threshold in the weather type are used as the control target, and the control target is used as the threshold according to the preset time period. Otherwise, the control processing is still performed according to the original threshold. If the number of compatible weather types is not above the preset threshold for the number of compatible weather types, the maximum value of the endpoint of the adjustment demand space of the compatible weather type and the minimum value of the threshold in the weather type are used as the control target. The control target is used as the threshold according to the second preset time period. In other cases, the control processing is still performed according to the original threshold.

[0123] The preset time period is longer than the second preset time period. When there are many weather types to adapt to, a longer preset time period is used; when there are fewer, a shorter second preset time period is used.

[0124] If a certain weather type has a large number of compatible weather types, the control target is used as the threshold with a longer preset time period; if the number is small, the control target is used with a shorter second preset time period.

[0125] By further refining the selection of time periods by adapting to the number of weather types, the application period of the control target can be dynamically adjusted when the number of weather types is different, thereby achieving a precise match between the regulation and management methods and the degree of adaptation.

[0126] This embodiment realizes a complete process from calculating the control ratio to constructing the regulation demand space and determining the regulation management method. Its core value is reflected in three aspects: First, it assesses the coverage of control weather types by controlling the control ratio, and no additional control is required when the coverage is wide; second, it assesses the degree of fit between the threshold and the regulation demand space by the number of suitable weather types, and no additional control is required when the fit is good; third, it dynamically adjusts the regulation method and time period when the degree of fit is different by adjusting the fit coefficient and the number of suitable weather types through multi-level judgment, thereby achieving a precise match between the regulation management method and the degree of fit.

[0127] Continuing with the calculation results of S3, the coordinated weather types are W3 and W4, both of which are identified as the controlling weather types.

[0128] S41 step: Control ratio = 2 / 2 = 1.0.

[0129] Determine if the control ratio 1.0 is greater than the preset control ratio threshold 0.80: If 1.0 is greater than 0.80, it is determined that the regulation and management method for energy storage devices other than the control weather type in the coordinated regulation weather type is that no regulation and control processing is required.

[0130] Since all coordinated weather types (W3 and W4) have been identified as controlled weather types with a control ratio of 1.0, which exceeds the preset control ratio threshold, there is no need to perform additional regulation and control on weather types other than the controlled weather types.

[0131] This embodiment implements a comprehensive scheduling method for new energy power plants. S1 determines the weather type for coordinated regulation by multi-level judgment of the degree of overlap in demand periods and the average value of demand, focusing energy storage regulation resources on the weather type with the most urgent demand. S2 determines the output regulation demand type by multi-level judgment of the proportion of coordinated regulation and the proportion of power generation, providing a hierarchical basis for determining the coordinated regulation strategy of energy storage devices. S3 determines the coordinated regulation strategy and control weather type by multi-level judgment of the regulation demand value, the proportion of power generation from demanding power plants, and the overall demand value, ensuring reliable power consumption while reducing the frequency of operation of energy storage devices. S4 determines the regulation management method of energy storage devices by multi-level judgment of the control ratio and the adjustment adaptation coefficient, realizing coordinated control of energy storage space across different weather types. Overall, this method constructs a complete technical closed loop from demand assessment to output regulation classification, and then to energy storage collaborative control and dynamic adjustment of regulation management through the coordinated linkage of weather type determination, output regulation demand type determination, coordinated regulation strategy determination, and regulation management method determination. Its core value is reflected in four aspects: First, by determining the weather type classification based on the average of the consumption demand value, it achieves precise matching between coordinated regulation weather type selection and consumption demand; second, through multi-level judgment of the coordinated regulation ratio and demand value, it achieves precise matching between output regulation demand type and regulation demand degree; third, through multi-level judgment of regulation demand value and comprehensive demand value, it achieves precise matching between coordinated regulation strategy and regulation demand; and fourth, through multi-level judgment of the regulation adaptability coefficient and the number of adaptable weather types, it achieves precise matching between regulation management method and adaptability degree.
