It has the characteristics of high intelligence, more stable operation and energy saving.

[0004] Nowadays, there are still some shortcomings in the energy-saving power supply system based on electric energy recovery and energy storage. Specifically, the energy-saving power supply based on electric energy recovery and energy storage is limited to the evaluation and prompting of the energy-saving power supply of the power supply system through the energy-saving power supply management information set of the power supply system, ignoring the influence of the reference threshold on the pre-execution mechanism of the power supply system energy recovery and energy storage obtained based on the analysis of the evaluation value of the power supply system recovered electric energy and the evaluation and prompting of the energy-saving power supply of the power supply system. Ignoring the analysis based on the evaluation value of the power supply system recovered electric energy may lead to incomplete evaluation results. Only relying on the energy-saving power supply management information set of the power supply system, it is impossible to fully understand the actual situation of the power supply system recovered electric energy and the potential energy-saving potential. Lack of comprehensive data and information support may lead to deviations in the evaluation results, resulting in the inability to effectively formulate the pre-execution mechanism of the power supply system recovered energy storage and the inability to formulate targeted measures and strategies. Ignoring the influence of the evaluation value of the power supply system recovered electric energy may lead to incomplete evaluation results. It affects the realization of energy-saving effects and cannot achieve the energy-saving effects to the greatest extent. Failure to take into account the impact of the reference threshold may lead to a lack of standardized guidance on the evaluation results. Lack of setting of reference thresholds may lead to a lack of comparison and measurement standards in the evaluation results, making it difficult to evaluate the energy-saving effects of the power supply system. Ignoring the impact of the reference threshold may lead to the inability to quantify the energy-saving effects of the power supply system. Lack of setting of reference thresholds may cause the evaluation results to fail to accurately reflect the energy-saving level of the power supply system, making it difficult to carry out effective energy-saving management and improvement. Failure to consider the impact of the reference threshold may lead to difficulty in identifying the room for improvement in the energy-saving power supply of the power supply system. Lack of clear reference standards may cause the evaluation results to fail to indicate which aspects need to be improved and optimized, limiting the improvement of energy-saving effects. Lack of reference to the reference threshold may make it difficult to determine reasonable energy-saving targets, which may lead to setting targets that are too high or too low, affecting the implementation and effectiveness of the energy-saving plan.

It can identify specific opportunities and potential problems in recycling electric energy in the power supply system, formulate energy storage pre-execution mechanisms in a targeted manner, improve execution effects, and help formulate corresponding pre-execution mechanisms to reduce risks and improve the reliability and stability of the power supply system. By analyzing the evaluation value of recycled electric energy, we can better understand the potential value and influencing factors of recycled electric energy, which helps to formulate strategies and measures to maximize energy-saving effects.

By comprehensively analyzing the recovered power operation data, abnormal conditions and potential problems in the system operation can be discovered in time, and corresponding measures can be taken to avoid failures and improve the reliability and stability of the power supply system. Comprehensive analysis of the recovered power information set and data is helpful to optimize the energy management strategy, improve energy utilization efficiency and energy conservation level. By reasonably analyzing the data, a more scientific energy management plan can be formulated to maximize the utilization of energy. Comprehensive analysis of the recovered power evaluation value can provide guidance for continuous improvement. By continuously monitoring and analyzing the data, the operation strategy and control method of the recovered power system can be adjusted and improved in time to continuously improve the system performance and energy conservation effect.

[0041] Furthermore, the power recovery evaluation value of the power supply system is used to evaluate the power recovery capability of the power supply system. It can not only be obtained by further analysis through the machine learning integrated model, using integrated methods such as random forest or gradient boosting tree to combine the prediction results of multiple basic models to obtain a more accurate power supply system recovery evaluation value, but also can be calculated in the following way. The specific calculation formula is:

[0042] In the formula, λ is the evaluation value of power supply system recovered electric energy, λ1 is the evaluation value of power supply system recovered electric energy operation, λ2 is the evaluation value of power supply system recovered electric energy storage system, μ1 is the set weight factor of power supply system recovered electric energy operation evaluation value, μ2 is the set weight factor of power supply system recovered electric energy storage system evaluation value.

[0043] In a specific embodiment, the calculation formula of the power supply system power recovery operation evaluation value is:

[0044]

[0045] In the formula, λ1 is the evaluation value of the power supply system's energy recovery operation, Q is the power supply system's cycle average energy storage recovery value, T is the power supply system's cycle average energy storage recovery duration, η is the proportion of the number of times the power supply system's energy storage recovery meets the load demand, Q0 is the power supply system's cycle average energy storage recovery limit value, T0 is the power supply system's cycle average energy storage recovery reference duration, η0 is the power supply system's cycle average energy storage recovery limit proportion of the number of times the power supply system's energy storage recovery meets the load demand, τ1 is the compensation factor for the set power supply system's cycle average energy storage recovery value, τ2 is the compensation factor for the set power supply system's cycle average energy storage recovery duration, τ3 is the compensation factor for the set power supply system's cycle average energy storage recovery duration proportion of the number of times the power supply system's energy storage recovery meets the load demand, and α is the correction factor for the set power supply system's energy recovery operation evaluation value.

[0046] It should be explained that the above-mentioned power supply system energy recovery operation evaluation value is calculated through the average energy storage value recovered during the power supply system cycle, the average energy storage time recovered during the power supply system cycle, and the proportion of times that the power supply system energy storage recovers to meet the load demand. Taking into account factors such as the average energy storage value recovered during the power supply system cycle, the average energy storage time recovered during the power supply system cycle, and the proportion of times that the power supply system energy storage recovers to meet the load demand, the power supply system's energy recovery operation status can be comprehensively evaluated. Not only can the average value and duration of the recovered energy storage be understood, but also whether the recovered energy storage meets the load demand, thereby more comprehensively evaluating the system's performance. By comprehensively considering the recovered energy storage value and duration, as well as the situation in which the recovered energy storage meets the load demand, the system's energy-saving potential can be more accurately identified. If the recovered energy storage value is high, the duration is long, and the number of times it meets the load demand is high, it means that the system has a good energy-saving effect. Otherwise, there may be energy-saving potential. Taking multiple factors into consideration It can provide guidance for the optimization of energy storage systems. By analyzing the operation evaluation value of recovered electric energy, the bottlenecks and room for improvement of the system can be found, the design and operation strategies of the energy storage system can be optimized in a targeted manner, and the performance and efficiency of the system can be improved. The reliability of the system can be evaluated by considering the proportion of times that the recovered energy storage meets the load demand. If the system can efficiently meet the load demand, it means that the system operation is stable and reliable; otherwise, there may be potential risks and problems, and further improvement and enhancement of the reliability of the system are needed. By analyzing the operation evaluation value of recovered electric energy, a more scientific and reasonable energy management plan can be formulated to improve energy utilization efficiency, reduce energy consumption costs, and achieve energy management optimization and energy conservation and emission reduction goals. The operation evaluation value of recovered electric energy of the power supply system can also be further analyzed through the machine learning integrated model. LightGBM is used to combine the prediction results of multiple basic models to obtain a more accurate operation evaluation value of recovered electric energy of the power supply system.

[0047] In a specific embodiment, the calculation formula of the evaluation value of the power supply system to recover the electric energy storage system is:

[0048] Wherein, λ2 is the evaluation value of the energy storage system recovered by the power supply system, N is the maximum capacity of the energy storage device recovered by the power supply system, TX is the response time of the energy storage device recovered by the power supply system, W is the peak power of the energy storage device recovered by the power supply system, N0 is the maximum defined capacity of the energy storage device recovered by the power supply system, TX0 is the permitted response time of the energy storage device recovered by the power supply system, W0 is the reference peak power of the energy storage device recovered by the power supply system, τ4 is the compensation factor of the maximum capacity of the energy storage device recovered by the power supply system, τ5 is the compensation factor of the response time of the energy storage device recovered by the power supply system, τ6 is the compensation factor of the peak power of the energy storage device recovered by the power supply system, and β is the correction factor of the evaluation value of the energy storage system recovered by the power supply system.

[0049] It should be explained that the above-mentioned evaluation value of the power supply system's energy storage system recovery is calculated through the maximum capacity of the power supply system's energy storage equipment recovery, the power supply system's energy storage equipment recovery response time, and the power supply system's energy storage equipment recovery peak power. Comprehensive consideration of factors such as the maximum capacity of the power supply system's energy storage equipment recovery, the power supply system's energy storage equipment recovery response time, and the power supply system's energy storage equipment recovery peak power can ensure that the energy storage capacity designed for the system is sufficient to meet actual needs, thereby improving the effectiveness and stability of the system. Considering the response time of the energy storage equipment recovery can evaluate the system's rapid response capability. A shorter response time means that the system can respond more quickly to grid demands or changes, improve the system's flexibility and response speed, and help cope with sudden load changes or grid fluctuations. Comprehensive consideration of the peak power of the energy storage equipment recovery can evaluate the system's support capability during peak loads. If the energy storage device has a higher peak power, The system can cope with load peaks more effectively, reduce grid pressure, and improve system stability and reliability. Considering multiple factors can optimize the system's operating efficiency. By comprehensively evaluating factors such as the capacity, response time, and peak power of the recovered energy storage system, a more reasonable operating strategy can be formulated to improve the system's energy utilization efficiency and operating efficiency, reduce energy consumption costs, and reasonably match the capacity, response time, and peak power of energy storage equipment to ensure that the system can operate stably under various working conditions, reduce potential safety risks, and ensure the safety and stability of the power supply system. The evaluation value of the power supply system's recovered energy storage system can also be further analyzed through a machine learning integrated model. XGBoost is used to combine the prediction results of multiple basic models to obtain a more accurate evaluation value of the power supply system's recovered energy storage system. The evaluation value of the power supply system's recovered energy storage system is used to evaluate the recovery energy storage capacity of the power supply system's recovered energy storage system.

[0050] The reference evaluation threshold acquisition module is used to analyze and obtain the pre-execution mechanism of energy storage recovery of the power supply system based on the evaluation value of power supply system power recovery, and compare and obtain the reference evaluation threshold of power supply system adaptation energy-saving power supply management.

[0051] Specifically, based on the power supply system's recovered electric energy evaluation value, the power supply system's energy storage recovery pre-execution mechanism is analyzed and obtained. The specific analysis process is: according to the power supply system's recovered electric energy evaluation value, the power supply system's energy storage recovery pre-execution mechanism is verified with the power supply system's belonging area stored in the power supply system database within the range of each power supply system's recovered electric energy evaluation value, the power supply system's energy storage recovery pre-execution mechanism is extracted, and the power supply system's energy storage recovery pre-execution start time point and the electric energy storage recovery peak value obtained during the electric energy storage recovery duration are obtained.

[0052] Furthermore, the reference evaluation threshold of the power supply system adaptation energy-saving power supply management is obtained by comparison. The specific analysis process is: obtaining the energy recovery and storage time point, energy recovery and storage duration and energy recovery and storage peak value in the power supply system energy recovery and storage pre-execution mechanism.
