[0064] Example 1
[0065] like Figures 1 to 5 As shown, the present invention provides a technical solution: a method for optimizing the consumption and dispatching of distributed new energy in power grids based on cloud-edge fusion computing, comprising the steps of: S1: edge processing of real-time power generation and adjustable load operation status data acquired through edge devices; S2: transmitting the edge-processed data to the cloud for operation condition design and constraint fusion calculation, and obtaining the corresponding distributed new energy operation demand load constraints and adjustable capacity load constraints under different operation conditions; S3: performing risk assessment and analysis on the corresponding power grid sub-nodes in the main distribution network of the power system based on the load constraints and the adjustable capacity load constraints, and obtaining the corresponding distributed new energy risk level of each power grid sub-node under different operation conditions; S4: optimizing the consumption and coordinated dispatching between each power grid sub-node in the main distribution network of the power system according to the new energy risk level, and generating a power system main distribution network consumption and coordinated dispatching optimization strategy to execute the distributed new energy consumption and coordinated dispatching work between each power grid sub-node of the corresponding main distribution network.
[0066] Specifically, S1: obtain the real-time power generation and adjustable load operation status data through edge devices for edge processing, and obtain the distributed new energy power generation data and adjustable load operation status data corresponding to each grid sub-node in the main distribution network of the power system in real time through distributed sensors (sensors include current sensors, voltage sensors, power factor sensors and frequency sensors, etc.) and monitoring equipment (monitoring equipment includes solar power generation monitoring equipment, wind power generation monitoring equipment, environmental and meteorological monitoring equipment and energy storage monitoring equipment); introduce edge computing nodes by configuring edge devices at each grid sub-node (the edge computing node is to configure corresponding edge devices at each grid sub-node so that the grid sub-node is marked as an edge computing node, that is, the grid sub-node is changed into an edge computing node, so that its data transmission process has the function of edge computing to reduce transmission delay) The distributed new energy power generation data and the adjustable load operation status data are processed at the edge (that is, the corresponding power generation power, load demand and energy storage device status are calculated according to the corresponding new energy power generation data and load operation status), and the distributed new energy power generation power, adjustable load demand and distributed energy storage device status data corresponding to each edge computing node are obtained.
[0067] In an embodiment of the present invention, distributed sensors and monitoring equipment are deployed in the main distribution network of the power system to achieve real-time data acquisition of each grid sub-node. These sensors are capable of monitoring the operating status of the adjustable system, including measuring current, voltage, power factor and frequency, etc. At the same time, the monitoring equipment is also equipped to obtain distributed renewable energy (such as solar energy, wind energy, etc.) power generation data, including the specific duration of power generation, the amount of power generation and the power generation environment information, etc. During the data collection process, data compression and encryption transmission technology are adopted to obtain the distributed renewable energy power generation data and adjustable load operating status data corresponding to each grid sub-node. By designing the configuration of edge devices for each grid sub-node in the main distribution network of the power system, each grid sub-node is evaluated, including its power load characteristics, existing infrastructure, communication capabilities, etc. Based on these evaluation results, an edge device configuration blueprint is designed, and based on the edge device configuration blueprint generated by the previous design, the functions of the edge computing nodes are integrated for each grid sub-node in the main distribution network of the power system, so as to ensure its smooth operation in the grid sub-node by assembling and debugging the designed edge devices, wherein each edge computing node includes a data processing unit, a storage unit and a communication interface with the main distribution network, and adopts embedded system technology to ensure that the edge computing node has real-time data processing capabilities. During the integrated design process, multiple functional tests and performance verifications are carried out to ensure that the equipment can operate stably and can respond to changes in the operating status of the power grid in a timely manner, so as to obtain the corresponding edge computing nodes in the main distribution network of the power system. Then, by using the previously integrated edge computing nodes, the distributed renewable energy power generation data and adjustable load operation status data acquired in real time are processed at the edge. Each edge computing node processes the collected data locally, and calculates the distributed renewable energy power generation power, adjustable load demand and distributed energy storage equipment status data through edge computing. Stream processing technology is used to achieve real-time data analysis and decision-making to ensure timely optimization of power grid operation. The data processing results will be used to support power dispatching, load balancing and energy storage management, and finally the distributed renewable energy power generation power, adjustable load demand and distributed energy storage equipment status data corresponding to each edge computing node are obtained.
[0068] Further, S2: using the Internet of Things technology to transmit the distributed renewable energy power generation, adjustable load demand and distributed energy storage device status data corresponding to each edge computing node to the cloud for operating condition design and constraint fusion calculation, so as to obtain the distributed renewable energy operating demand load constraint and adjustable capacity load constraint corresponding to each edge computing node under different operating conditions;
[0069] In an embodiment of the present invention, the distributed renewable energy power generation, adjustable load demand and distributed energy storage device status data obtained by edge computing of sensors and data acquisition devices deployed at each edge computing node are transmitted to the cloud in real time by using the Internet of Things technology. In a specific implementation, the edge node collects data using a wireless communication protocol (such as LoRa, Zigbee or NB-IoT) to ensure stable transmission of data in different network environments, and uses data encryption technology to ensure information security, ensuring that all data is not tampered with during transmission. The operating function requirements and performance targets corresponding to each edge computing node obtained by cloud analysis are designed for the corresponding edge computing node in combination with a specific algorithm model (such as a rule-based decision tree or optimization algorithm) to design and generate different operating condition design scenarios, which include maximum power generation capacity, minimum load demand and optimal energy storage state, and the distributed renewable energy power generation, adjustable load demand and distributed energy storage device status data corresponding to each edge computing node are divided into time periods for operating condition scenarios, so as to analyze the environmental changes and load fluctuations of each edge computing node in different time periods, and use the time series analysis method ... The operating conditions of the power generation power, adjustable load demand and energy storage device status of the edge computing node are classified to form a time period data set under the corresponding operating conditions, including the power generation power, adjustable load demand and energy storage device status. The power generation power and energy storage device status of each edge computing node under different operating conditions are fused and calculated. The power generation power and energy storage status of each edge node are constrained by linear programming method, and an optimization model is constructed to solve the power load constraints that meet the operating requirements of each node. The model is solved by Matlab or optimization software to obtain the demand load constraints of each edge computing node under different operating conditions. Then, by performing a fusion calculation of the adjustable capacity load constraints for the power generation and load demand of each edge computing node under different operating conditions, a detailed analysis of the node load demand is performed by introducing a dynamic scheduling strategy and an adjustable load model, and advanced algorithms (such as genetic algorithms or particle swarm optimization) are used to model and evaluate the adjustable capacity of each node, and the range and restrictions of the adjustable load are determined. In the calculation process, the real-time data and prediction model are combined to optimize the adjustable capacity load of each node to achieve the purpose of ensuring the overall stability of the power system and optimizing scheduling, and finally the adjustable capacity load constraints corresponding to each edge computing node under different operating conditions are obtained.
[0070] Further, S3: based on the distributed renewable energy operation demand load constraints and adjustable capacity load constraints corresponding to each edge computing node under different operating conditions, a risk assessment analysis is performed on the corresponding grid sub-nodes in the main distribution network of the power system to obtain the distributed renewable energy risk level corresponding to each grid sub-node under different operating conditions;
[0071] In an embodiment of the present invention, a suitable risk assessment calculation formula is formed by combining the distributed new energy operation demand load constraints and adjustable capacity load constraints corresponding to different operating conditions, external uncertainty factors, uncertainty risk impact weight coefficients and related parameters obtained by previous analysis and calculation to evaluate and calculate the corresponding grid sub-nodes in the main distribution network of the power system, so as to quantitatively calculate the risk level of each grid sub-node, and finally obtain the distributed new energy risk level corresponding to each grid sub-node under different operating conditions.
[0072] Further, S4: according to the distributed renewable energy risk level corresponding to each grid sub-node under different operating conditions, the coordinated dispatching optimization of the consumption between each grid sub-node in the main distribution network of the power system is optimized, and the coordinated dispatching optimization strategy of the consumption of the main distribution network of the power system is generated to execute the coordinated dispatching of the consumption of distributed renewable energy between each grid sub-node of the corresponding main distribution network.
[0073] In an embodiment of the present invention, by combining the distributed new energy risk levels corresponding to each grid sub-node under different operating conditions obtained by previous quantitative calculation, the consumption and dispatching needs of each corresponding grid sub-node in the main distribution network of the power system are predicted and analyzed, so as to predict and analyze the consumption and dispatching needs of each grid sub-node under specific circumstances, and use machine learning algorithms to train historical data to accurately predict the new energy consumption needs of each grid sub-node, and by combining the distributed new energy consumption and dispatching needs obtained by previous prediction and analysis, the consumption optimization targets of the corresponding grid sub-nodes in the main distribution network of the power system are analyzed, so as to set the optimization objective function, such as minimizing energy loss or maximizing new energy utilization, by adopting optimization algorithms such as linear programming or integer programming, and at the same time When determining the constraints, including the maximum load, minimum power generation and power generation scheduling restrictions of the grid sub-nodes, and using optimization software such as MATLAB or GAMS, solve the optimization model to obtain the distributed new energy consumption optimization target of each grid sub-node under different operating conditions. Then, by combining the previously obtained optimization targets, the consumption coordinated scheduling optimization is performed between each grid sub-node in the main distribution network of the power system, so as to establish a coordinated scheduling model between the grid sub-nodes, define the power exchange and power balance relationship between the sub-nodes, and use a coordinated scheduling algorithm, such as a distributed algorithm or an integrated algorithm, to ensure that each sub-node achieves the optimal power allocation while meeting the consumption optimization target. Through simulation software such as PSS / E or DIgSILENT PowerFactory, simulate the implementation effect of coordinated scheduling, adjust the scheduling strategy, ensure the overall safety and stability of the system, thereby optimizing and generating the consumption coordinated scheduling optimization strategy of the main distribution network of the power system, guiding the actual distributed new energy consumption coordinated scheduling work, and performing corresponding execution and monitoring, and finally executing the distributed new energy consumption coordinated scheduling work between each grid sub-node of the corresponding main distribution network.

Seasonal and random load fluctuations are introduced in the formula, so that the edge computing node can flexibly respond to load changes. This dynamic adjustment capability helps to achieve optimal energy management and distribution under different operating conditions. Secondly, through in-depth analysis of power generation and load demand, better load balance can be achieved to avoid potential risks caused by supply and demand imbalance, such as power shortage or surplus. The adjustable basic load and its upper and lower limits in the formula provide system operators with more strategic options. According to different needs and operating conditions, the operation strategy can be quickly adjusted to meet the real-time load demand. At the same time, by real-time monitoring and adjusting the load constraints of edge computing nodes, the system instability caused by sudden load fluctuations can be reduced to ensure the safe and reliable operation of the power grid. By combining the data analysis capabilities of edge computing and cloud, more scientific decisions can be made based on historical and real-time data. This data-driven approach can improve the intelligence level of the overall system. Overall, the adjustable capacity load constraint fusion calculation formula has significant advantages in improving the operating efficiency, flexibility and stability of new energy systems, and provides strong support for the combination of smart grids and edge computing. This formula can realize the adjustable capacity load constraint fusion calculation process of the power generation power and load demand of each edge computing node in the corresponding time period under different operating conditions, thereby improving the accuracy and applicability of the adjustable capacity load constraint fusion calculation formula.
[0150] Furthermore, the risk assessment analysis in step S3 is calculated by a distributed new energy risk level calculation formula, and the distributed new energy risk level calculation formula is specifically:

[0152] In the formula, R i (t, C) is the distributed new energy risk level of the ith edge computing node in the corresponding time period t under the operating condition C, L i (t, C) is the distributed renewable energy operation demand load constraint of the ith edge computing node under the operating condition C in the corresponding time period t, U(C) is the external uncertainty factor under the operating condition C, β is the uncertainty risk impact weight coefficient, A i(t, C) is the adjustable capacity load constraint of the i-th edge computing node in the corresponding time period t under the operating condition C, and ε is a non-zero adjustment constant.
[0153] The present invention obtains a distributed new energy risk level calculation formula by using a specific mathematical model and after verification, which is used to perform risk assessment and analysis on the corresponding power grid sub-nodes in the main distribution network of the power system. The distributed new energy risk level calculation formula can quantify the new energy risk level of different power grid sub-nodes under specific conditions by combining the operating demand load constraint and the adjustable capacity load constraint. This quantification provides a scientific basis for decision-making and helps to identify high-risk areas. By introducing external uncertainty factors and uncertainty risk impact weight coefficients, the formula can adapt to different operating conditions, reflect system state changes in real time, and ensure that risk management strategies can be flexibly adjusted when facing different environmental factors. The risk assessment results can be directly used for consumption and coordinated scheduling optimization. By understanding the risk level of each power grid sub-node, power scheduling can be arranged more reasonably to reduce the imbalance between supply and demand caused by new energy fluctuations. In addition, in the main distribution network of the power system, scheduling optimization is performed according to the risk assessment results, which can effectively respond to emergencies (such as equipment failures, weather changes, etc.) and improve the resilience and reliability of the overall system. The real-time data provided by the edge computing node enables risk assessment to be based on the latest information, avoiding decision-making errors caused by lagging data. This real-time nature enables the power system to respond quickly to changes. In summary, through the application of this series of steps and formulas, not only an effective risk management and dispatch optimization solution is provided for distributed renewable energy in the main distribution network of the power system, but also a solid foundation is laid for the development of future smart grids. This comprehensive risk assessment and dispatch strategy will promote the sustainable, stable and efficient operation of the power system. Therefore, this formula fully considers the distributed renewable energy risk level R of the ith edge computing node in the corresponding time period t under the operating condition C. i (t,C), the distributed renewable energy operation demand load constraint L of the ith edge computing node in the corresponding time period t under the operating condition C i (t, C), the external uncertainty factor U(C) under operating condition C, the uncertainty risk impact weight coefficient β, the adjustable capacity load constraint A of the i-th edge computing node in the corresponding time period t under operating condition C i (t, C), a non-zero adjustment constant ε, based on the distributed new energy risk level R of the ith edge computing node in the corresponding time period t under the operating condition C i The correlation between (t,C) and the above parameters constitutes a functional relationship This formula can realize the risk assessment and analysis process of the corresponding grid sub-nodes in the main distribution network of the power system, thereby improving the accuracy and applicability of the distributed new energy risk level calculation formula.

[0155] As attached Figure 6 As shown, different from the previous embodiment, this embodiment further records that step S4 performs risk assessment analysis on the corresponding grid sub-nodes in the main distribution network of the power system based on the load constraint and the adjustable capacity load constraint, and obtains the distributed new energy risk level corresponding to each grid sub-node under different operating conditions, including the following steps:
[0156] S41: According to the distributed renewable energy risk level of each grid sub-node under different operating conditions, the consumption and dispatching demand of each grid sub-node in the main distribution network of the power system is predicted and analyzed to obtain the distributed renewable energy consumption and dispatching demand of each grid sub-node under different operating conditions;
[0157] In an embodiment of the present invention, by combining the distributed new energy risk levels corresponding to each grid sub-node under different operating conditions obtained by previous quantitative calculation, the corresponding grid sub-nodes in the main distribution network of the power system are predicted and analyzed to predict and analyze the consumption and dispatching needs of each grid sub-node under specific circumstances, and the historical data is trained using a machine learning algorithm to accurately predict the new energy consumption demand of each grid sub-node, and the results are organized into a report to ensure that reliable input is provided for subsequent steps, and finally the distributed new energy consumption and dispatching needs corresponding to each grid sub-node under different operating conditions are obtained.
[0158] S42: Based on the distributed renewable energy consumption dispatching requirements corresponding to each grid sub-node under different operating conditions, the corresponding grid sub-nodes in the main distribution network of the power system are analyzed for consumption optimization targets, so as to obtain the distributed renewable energy consumption optimization targets corresponding to each grid sub-node under different operating conditions;
[0159] In an embodiment of the present invention, by combining the distributed new energy consumption and dispatching requirements corresponding to each grid sub-node under different operating conditions obtained by previous prediction and analysis, the corresponding grid sub-nodes in the main distribution network of the power system are analyzed for the consumption optimization targets, so as to set the optimization objective function by adopting optimization algorithms such as linear programming or integer programming, such as minimizing energy loss or maximizing new energy utilization. At the same time, the constraints, including the maximum load, minimum power generation and power generation dispatching restrictions of the grid sub-nodes, are determined, and the optimization model is solved by using optimization software such as MATLAB or GAMS to obtain the distributed new energy consumption optimization targets of each grid sub-node under different operating conditions. The analysis results are presented in a clear form to facilitate decision makers to formulate subsequent dispatching strategies, and finally the distributed new energy consumption optimization targets corresponding to each grid sub-node under different operating conditions are obtained.
[0160] S43: Based on the distributed new energy consumption optimization targets corresponding to each grid sub-node under different operating conditions, the consumption coordinated dispatch optimization is optimized between each grid sub-node in the main distribution network of the power system, and the power system main distribution network consumption coordinated dispatch optimization strategy is generated to execute the distributed new energy consumption coordinated dispatch work between each grid sub-node of the corresponding main distribution network.
[0161] In an embodiment of the present invention, after clarifying the distributed new energy consumption optimization target of each grid sub-node, the consumption collaborative scheduling optimization is performed between each grid sub-node in the main distribution network of the power system, so as to establish a collaborative scheduling model between the grid sub-nodes, define the power exchange and power balance relationship between the sub-nodes, and use a collaborative scheduling algorithm, such as a distributed algorithm or an integrated algorithm, to ensure that each sub-node achieves the optimal power allocation while meeting the consumption optimization target. Through simulation software, such as PSS / E or DIgSILENT PowerFactory, the implementation effect of collaborative scheduling is simulated, the scheduling strategy is adjusted, and the overall safety and stability of the system is ensured, thereby optimizing and generating the consumption collaborative scheduling optimization strategy of the main distribution network of the power system, guiding the actual distributed new energy consumption collaborative scheduling work, and performing corresponding execution and monitoring, and finally executing the distributed new energy consumption collaborative scheduling work between each grid sub-node of the corresponding main distribution network.
[0162] Example 5
[0163] This embodiment is different from the previous one in that it further provides a comparative experiment between the present scheme and two schemes of the prior art, illustrating that the present scheme optimizes the coordinated dispatching of each grid sub-node in the main distribution network of the power system according to the risk level of each grid sub-node under different operating conditions. This process will optimize the power distribution and consumption strategies between each grid sub-node by analyzing the risk situation of each node to ensure the efficient operation of the power system. The coordinated dispatching optimization of consumption not only considers the balance of power supply and demand, but also makes full use of the characteristics of distributed new energy to maximize its power generation potential. Through scientific scheduling algorithms, it can achieve power complementarity and resource sharing between different nodes and reduce dependence on traditional fossil energy, which not only improves the reliability and stability of power supply.
[0164] In comparative experiment 1, after comparing this solution with the first comparative file, it was found that this solution has the following effects:
[0165] D1 represents the existing technical solution: a comprehensive energy dispatch optimization method for improving the absorption capacity of distributed new energy;
[0166] D2 represents this technical solution.
[0167]
[0168]
[0169] In comparative experiment 2, this solution is compared with the second comparative file and the following effects are found:
[0170]
[0171] It should be noted that D1 represents the existing technical solution: a multi-objective optimization method for distributed renewable energy distribution network scheduling
[0172] D2 represents this technical solution.
[0173] The distributed new energy consumption dispatch optimization method for power grid based on cloud-edge fusion computing proposed by the present invention, compared with the prior art, has the beneficial effect of using distributed sensors and monitoring equipment to obtain the distributed new energy power generation data and adjustable load operation status data of each power grid sub-node on the main distribution network of the power system in real time. The acquisition of distributed new energy power generation data enables power managers to clearly understand the power generation of different distributed new energy sources, including the contribution of renewable resources such as solar energy and wind energy, so as to effectively evaluate their role in the overall energy supply. In addition, real-time monitoring of the operation status data of the adjustable system load enables the power dispatch center to flexibly respond to load fluctuations, further promoting the intelligence and efficient operation of the power system. At the same time, by configuring edge devices at each power grid sub-node and introducing edge computing nodes to perform edge data processing on the distributed new energy power generation data and the adjustable load operation status data, the corresponding distributed new energy power generation power, adjustable load demand and distributed energy storage equipment status data are obtained. This process can generate accurate power generation and load status information in real time, supporting managers to make more informed decisions in power dispatching. For example, through real-time analysis of renewable energy power generation, the dispatch center can timely adjust the operation strategy of the power grid to maximize the use of renewable energy. By monitoring the adjustable load demand and the status of energy storage equipment, it helps the power system to reasonably distribute electricity during peak hours to avoid imbalance between supply and demand. The low latency characteristics brought by edge computing enable the power system to quickly respond to external environmental changes and emergencies, providing strong support for the intelligent management of the power system. Secondly, by using the distributed renewable energy power generation, adjustable load demand and distributed energy storage equipment status data of each edge computing node to transmit to the cloud, cloud-edge fusion monitoring and management of the entire power system can be achieved. This real-time data collection capability enables the power system to quickly respond to environmental changes and load fluctuations, thereby optimizing energy dispatch. By using the cloud to design the operating conditions for the corresponding edge computing nodes, this step integrates the requirements and performance goals of each node, making the designed operating conditions more targeted and ensuring that each edge node can achieve the set goals when operating under specific conditions. By combining different operating conditions to perform constraint fusion calculations on the operating demand load for the power generation power and energy storage device status corresponding to each edge computing node, it can help identify and optimize the energy demand and supply matching of each node. This step helps to clarify the minimum and maximum operating load requirements of each node under different conditions, ensuring that each edge node can operate stably and avoid overload or underload conditions, thereby improving the flexibility and adaptability of the entire power system.By performing constraint fusion calculation of the adjustable capacity load corresponding to the power generation and operating load demand of each edge computing node under different operating conditions, it can help identify the regulation potential of each edge computing node, so as to manage the load demand more effectively. This step focuses on the adjustable capacity of each node, so that the power system can identify the load regulation potential under different operating conditions under unstable energy supply, and formulate corresponding scheduling strategies, so as to better realize the perception and regulation control capabilities of distributed new energy and adjustable system loads with low voltage access. Then, based on the distributed new energy operation demand load constraints and adjustable capacity load constraints corresponding to each edge computing node under different operating conditions, the corresponding grid sub-nodes in the main distribution network of the power system are risk assessed and analyzed. This process will help to fully understand the risk level of each grid node in different scenarios, including potential risks such as insufficient power generation capacity, load overload and energy storage equipment failure. Through quantitative evaluation, the risk level of each node can be intuitively presented, helping operation and maintenance personnel to quickly identify high-risk areas and formulate corresponding emergency plans. This risk assessment also provides an important basis for subsequent scheduling optimization, ensuring that the power system can respond in an orderly manner in the face of emergencies and reduce the risk of power outages and equipment damage. Finally, by optimizing the coordinated dispatching of each grid sub-node in the main distribution network of the power system according to the risk level of each grid sub-node under different operating conditions, this process will optimize the power distribution and consumption strategies between each grid sub-node by analyzing the risk situation of each node to ensure the efficient operation of the power system. The coordinated dispatching optimization of consumption not only takes into account the balance of power supply and demand, but also makes full use of the characteristics of distributed new energy and maximizes its power generation potential. Through scientific scheduling algorithms, it can achieve power complementarity and resource sharing between different nodes and reduce dependence on traditional fossil energy. This not only improves the reliability and stability of power supply, but also plays a positive role in promoting the widespread application of renewable energy, thereby effectively reducing the scheduling pressure faced by power system dispatchers in power system operation.
