[0002] With the continuous development of the power system, its complexity and scale are increasing. How to ensure the stable operation of the power system and achieve the optimal allocation of power resources has become an urgent problem to be solved.

[0003] Traditional power management methods often focus on a single power generation, transmission or distribution link, while ignoring the synergy between the source (power generation equipment), grid (power network), load (load equipment) and storage (energy storage equipment) in the power system. In the prior art, source-grid-load-storage integration refers to the construction of a new power system with a high degree of source-grid-load-storage integration by optimizing and integrating local power supply side, grid side, load side and energy storage side resources. Integrate distributed energy sources such as solar energy and wind energy, power grids, loads and energy storage systems to achieve multi-energy complementarity and coordinated operation. This decentralized management method is prone to problems such as imbalance in power supply and demand, energy waste and decreased stability of the power system. Therefore, how to more effectively utilize the resources of power generation equipment and energy storage equipment and reduce energy waste has become an urgent problem to be solved. Summary of the invention

[0004] The present invention provides an electric power balancing method and management system for power system source-grid-load-storage coordination, which is used to more effectively utilize the resources of power generation equipment and energy storage equipment, which can not only reduce energy waste but also improve the resource utilization efficiency of the entire power system.

[0005] In a first aspect, the present invention provides a power balancing method for power system source-grid-load-storage coordination, which is applied to a power management system, wherein the power management system includes: a power dispatching platform and power generation equipment, load equipment and energy storage equipment connected through a power network; the method includes: The power dispatching platform broadcasts power balancing dispatching instructions to the power generation equipment, the load equipment and the energy storage equipment; The power generation equipment responds to the power balance dispatch instruction, obtains the power generation characteristic parameters within the next preset measurement cycle, determines the predicted power generation according to the power generation characteristic parameters, and sends the predicted power generation to the power dispatch platform; The power generation device obtains the actual current storage capacity of the energy storage device in response to the power balance dispatch instruction, and sends the actual storage capacity to the power dispatch platform; The load device responds to the power balance scheduling instruction, obtains the predicted power consumption within the next preset measurement period, and sends the predicted power consumption to the power scheduling platform; The power dispatching platform determines the power balance dispatching parameters according to the predicted power generation, the actual stored power and the predicted power consumption, wherein the power balance dispatching parameters include a power balance dispatching period and a power balance dispatching vector, and the balance dispatching vector is used to determine the power output direction and power output of the power generation equipment and the energy storage equipment within the power balance dispatching period; The power generation equipment is a photovoltaic power generation equipment; correspondingly, obtaining the power generation characteristic parameters within the next preset measurement cycle and determining the predicted power generation according to the power generation characteristic parameters include: The power generation equipment determines the predicted power generation according to the illumination characteristic parameter and the temperature characteristic parameter in the power generation characteristic parameters.

[0006] In the above scheme, by acquiring the power generation characteristic parameters of the power generation equipment and the predicted power consumption of the load equipment, as well as the current actual storage power of the energy storage equipment in real time, the power balance dispatching parameters can be quickly calculated, thereby improving the efficiency of power balance. Then, by comprehensively considering the data of power generation, load and energy storage, more reasonable power balance dispatching parameters can be formulated, which helps to avoid the imbalance of power supply and demand, thereby enhancing the stability of the power system. In addition, adjusting the power balance dispatching parameters according to real-time data can more effectively utilize the resources of power generation equipment and energy storage equipment. It can not only reduce energy waste, but also improve the resource utilization efficiency of the entire power system. In addition, the power balance dispatching instructions are broadcast to the power generation equipment, load equipment and energy storage equipment through the power dispatching platform, realizing the coordinated control among the three. This coordinated control helps to ensure that all links of the power system can work according to the predetermined plan, thereby improving the coordination and consistency of the entire system.

[0007] It is worth noting that by comprehensively considering the power generation characteristic parameters of photovoltaic power generation equipment, such as the light intensity curve, the ambient temperature curve, and the light angle curve, the power generation in the next preset measurement cycle can be predicted more accurately. The power dispatching platform can formulate more reasonable power balance dispatching parameters based on the predicted power generation, combined with the predicted power consumption of the load equipment and the actual storage power of the energy storage equipment, so as to optimize the dispatching strategy of photovoltaic power generation. When the light is sufficient, the temperature is suitable, and the light angle is appropriate, the photovoltaic power generation equipment can give full play to its power generation capacity and provide more electricity for the power system. Under unfavorable conditions such as insufficient light or excessive temperature, the power dispatching platform can adjust the dispatching strategy in advance to reduce the ineffective operation of photovoltaic power generation equipment, thereby improving resource utilization. The above scheme can achieve accurate power generation prediction, which helps the power dispatching platform to better grasp the fluctuation of photovoltaic power generation, so as to formulate a more stable power dispatching plan and enhance the stability of the power system.

[0008] Optionally, the load device obtains the predicted power consumption in the next preset measurement period in response to the power balance scheduling instruction, including: The load device determines the predicted power consumption in the next preset measurement cycle based on the power consumption in the current preset measurement cycle, the power consumption in the previous preset measurement cycle, and the predicted power consumption in the previous preset measurement cycle in the historical power consumption of the load device.

[0009] Optionally, the predicted power consumption in the next preset measurement period is obtained by the following formula: in, The predicted power consumption in the next preset measurement cycle. To preset the speed adjustment parameters, The power consumption in the current preset measurement cycle in the historical power consumption. The power consumption in the last preset measurement cycle in the historical power consumption. It is the predicted power consumption in the last preset measurement cycle.

[0010] In the above scheme, by comprehensively considering the historical power consumption data of the load equipment, including the power consumption in the current preset measurement cycle, the power consumption in the previous preset measurement cycle, and the predicted power consumption in the previous preset measurement cycle, the power consumption in the next preset measurement cycle can be predicted more accurately. This prediction method based on historical data makes full use of the time series characteristics of the power consumption of the load equipment and improves the accuracy and reliability of the prediction. Accurate power consumption prediction data provides an important decision-making basis for the power dispatching platform. The power dispatching platform can formulate more reasonable power balance dispatching parameters based on the predicted power consumption, combined with the predicted power generation of the power generation equipment and the actual storage power of the energy storage equipment. This not only helps to balance the supply and demand relationship of the power system, but also effectively reduces the occurrence of power shortage or surplus, and improves the overall operation efficiency of the power system. In addition, based on accurate power consumption prediction, the load equipment can operate more stably. The power dispatching platform can adjust the operating status of the load equipment in advance according to the prediction results to avoid equipment failure or damage caused by insufficient or excessive power supply. At the same time, this also helps to extend the service life of the load equipment and reduce the cost of maintenance and replacement.

[0011] Optionally, the power dispatching platform determines the power balance dispatching parameters according to the predicted power generation, the actual stored power and the predicted power consumption, including: If the power dispatching platform determines that the characteristic ratio between the predicted power generation and the predicted power consumption is greater than or equal to a preset safety threshold, the power dispatching platform determines a first balance dispatching vector and a second balance dispatching vector based on the predicted power generation and the predicted power consumption. The first balance dispatching vector is used to indicate that the power generation equipment outputs electric energy of the predicted power consumption to the load equipment within the power balance dispatching period, and the second balance dispatching vector is used to indicate that the power generation equipment outputs electric energy of the difference between the predicted power generation and the predicted power consumption to the energy storage equipment within the power balance dispatching period. The power balance dispatching vector includes the first balance dispatching vector and the second balance dispatching vector.

[0012] In the above scheme, when the power dispatching platform determines that the characteristic ratio between the predicted power generation and the predicted power consumption is greater than or equal to the preset safety threshold, it means that the predicted power generation of the power generation equipment can meet or even exceed the predicted power consumption of the load equipment. At this time, the power dispatching platform determines the first balance dispatching vector to ensure that the power generation equipment outputs the predicted power consumption to the load equipment within the power balance dispatching cycle to meet the power demand of the load equipment. At the same time, by determining the second balance dispatching vector, the power generation equipment is instructed to output the power of the difference between the predicted power generation and the predicted power consumption to the energy storage equipment to achieve reasonable storage of power. This strategy helps to optimize the supply and demand balance of the power system and ensure a stable supply of power. When the predicted power generation is sufficient, the power dispatching platform guides the power generation equipment to transfer the excess power to the energy storage equipment for storage through the second balance dispatching vector. This can not only avoid the waste of power, but also release power through the energy storage equipment when the subsequent power demand peaks or the power generation capacity is insufficient, so as to ensure the stable operation of the power system. Therefore, the technical effect helps to improve the efficient utilization rate of energy storage equipment and achieve the optimal configuration of power. Through the intelligent dispatching of the power dispatching platform, the operating status of power generation equipment and energy storage equipment can be flexibly adjusted according to the ratio of predicted power generation to predicted power consumption, so as to achieve reasonable distribution and efficient use of electric energy, which will help reduce the occurrence of power shortage or surplus, reduce the operating cost of the power system, and improve the overall efficiency of the power system. It can be seen that the above scheme introduces the concepts of power balance dispatching parameters and balance dispatching vectors, so that the power dispatching platform can flexibly adjust the power balance dispatching strategy according to the real-time operating status of the power system. This helps to enhance the flexibility and reliability of the power system, improve the power system's ability to respond to emergencies, and ensure the stable operation of the power system.

[0013] Optionally, the power dispatching platform determines the power balance dispatching parameters according to the predicted power generation, the actual stored power and the predicted power consumption, including: If the power dispatching platform determines that the characteristic ratio between the predicted power generation and the predicted power consumption is less than a preset safety threshold, the power dispatching platform determines a third balance dispatching vector and a fourth balance dispatching vector based on the predicted power generation and the predicted power consumption, the third balance dispatching vector being used to indicate that the power generation device outputs the predicted power consumption electric energy to the load device within the power balance dispatching period, the fourth balance dispatching vector being used to indicate that the energy storage device outputs the absolute value of the difference between the predicted power generation and the predicted power consumption electric energy to the load device within the power balance dispatching period, and the power balance dispatching vector includes the third balance dispatching vector and the fourth balance dispatching vector.

[0014] In the above scheme, when the power dispatching platform determines that the characteristic ratio between the predicted power generation and the predicted power consumption is less than the preset safety threshold, it means that the predicted power generation of the power generation equipment cannot meet the predicted power consumption of the load equipment. In this case, the power dispatching platform determines the third balance dispatching vector to ensure that the power generation equipment outputs the predicted power consumption to the load equipment within the power balance dispatching cycle, although this part of the power may not be enough to fully meet the load demand. But more importantly, the power dispatching platform also determines the fourth balance dispatching vector to instruct the energy storage device to output the power of the absolute value of the difference between the predicted power generation and the predicted power consumption to the load equipment within the power balance dispatching cycle, thereby effectively supplementing the power supply shortage of the power generation equipment and ensuring the stability and reliability of the power supply. In the case of insufficient predicted power generation, the emergency response capability of the energy storage device as an important part of the power system is particularly important. Under the guidance of the fourth balance dispatching vector, the energy storage device can quickly provide the required power to the load equipment, effectively alleviating the pressure of power shortage. This technical effect not only improves the emergency response capability of the energy storage device, but also enhances the risk resistance of the entire power system.

[0015] In the case of imbalance between power supply and demand, the power dispatching platform achieves optimal allocation of power resources by reasonably determining the third and fourth balanced dispatching vectors. On the one hand, it ensures the basic power demand of load equipment; on the other hand, through the supplementary power supply of energy storage equipment, it avoids serious consequences such as system paralysis or large-scale power outages caused by power shortages. This optimal allocation strategy helps to reduce the operating cost of the power system and improve the utilization efficiency of power resources.

[0016] It can be seen that when determining the power balance dispatching parameters, the power dispatching platform needs to comprehensively consider multiple factors such as predicted power generation, actual stored power, and predicted power consumption, and flexibly adjust the direction and size of the balance dispatching vector according to the size of the characteristic ratio, thereby promoting the improvement of the intelligence and automation level of the power system.

[0017] Optionally, the power dispatching platform determines the power balance dispatching parameters according to the predicted power generation, the actual stored power and the predicted power consumption, and further includes: The power dispatching platform updates the power balance dispatching period according to the characteristic ratio.

[0018] In the above scheme, the power dispatching platform updates the power balance dispatching cycle according to the characteristic ratio (i.e., the ratio between the predicted power generation and the predicted power consumption). By real-time monitoring and analyzing the operating status of the power system, the power dispatching platform can dynamically adjust the dispatching cycle to better adapt to the changes in the power system and ensure the stability and reliability of power supply. The update of the power balance dispatching cycle helps the power dispatching platform to arrange power production and consumption more accurately, thereby optimizing the allocation of power resources. In the case of an imbalance in power supply and demand, by adjusting the dispatching cycle, the power dispatching platform can better coordinate the work of power generation equipment and energy storage equipment, ensure the full utilization of power resources, and avoid waste and shortages. This technical effect helps to improve the overall efficiency of the power system and reduce operating costs.

[0019] Moreover, the power dispatching platform updates the power balance dispatching cycle according to the characteristic ratio, which helps to enhance the stability and security of the power system. By dynamically adjusting the dispatching cycle, the power dispatching platform can more effectively respond to emergencies and abnormal situations in the power system, such as power shortages and equipment failures. This technical effect helps to ensure the stable operation of the power system and avoid serious consequences such as large-scale power outages. In addition, the process of updating the power balance dispatching cycle according to the characteristic ratio of the power dispatching platform promotes the improvement of the intelligence and automation level of the power system, making power dispatching more accurate, efficient and reliable.

[0020] Optionally, after the power dispatching platform determines the power balance dispatching parameters according to the predicted power generation, the actual stored power and the predicted power consumption, it further includes: The power dispatching platform sends the power balance dispatching parameters to the power generation equipment and the energy storage equipment, so that the power generation equipment and / or the energy storage equipment transfer electric energy according to the power balance dispatching parameters.

[0021] In the above scheme, after determining the power balance dispatch parameters, the power dispatch platform promptly sends these parameters to the power generation equipment and energy storage equipment, ensuring the accuracy of power system regulation. The power generation equipment and energy storage equipment can accurately adjust their power output or storage status according to the received power balance dispatch parameters, thereby achieving the supply and demand balance of the power system. This precise regulation helps to avoid power surplus or shortage and ensure the stable operation of the power system.

[0022] By sending power balance dispatch parameters through the power dispatch platform, power generation equipment and energy storage equipment can transfer power according to actual needs, thereby improving the utilization efficiency of power resources. During peak power demand periods, power generation equipment can increase power output, and energy storage equipment can release stored power when necessary to meet load demand. During low power demand periods, power generation equipment can reduce power output, and energy storage equipment can store excess power for emergency use. This flexible power transmission method helps reduce the operating cost of the power system and improve overall economic benefits.

[0023] In addition, the power dispatching platform sends power balance dispatching parameters to power generation equipment and energy storage equipment, allowing these devices to quickly respond to changes in the power system. When power supply and demand are unbalanced or emergencies occur, power generation equipment and energy storage equipment can quickly adjust according to the power balance dispatching parameters to ensure the stability and reliability of the power system. This fast response speed helps reduce the risk of power system failures and improve users' power experience.

The power balance dispatching parameters include a power balance dispatching period and a power balance dispatching vector. The balance dispatching vector is used to determine the power output direction and power output of the power generation equipment and the energy storage equipment within the power balance dispatching period.

[0025] The first balancing dispatch vector is used to instruct the power generation device to output the electric energy of the predicted power consumption to the load device within the power balancing dispatch period. The second balancing dispatch vector is used to instruct the power generation device to output the electric energy of the difference between the predicted power generation and the predicted power consumption to the energy storage device within the power balancing dispatch period. The power generation equipment is a photovoltaic power generation equipment; correspondingly, obtaining the power generation characteristic parameters within the next preset measurement cycle and determining the predicted power generation according to the power generation characteristic parameters include: The power generation equipment determines the predicted power generation according to the illumination characteristic parameter and the temperature characteristic parameter in the power generation characteristic parameters.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0033] With the rapid development of the power system and the transformation of the energy structure, realizing the coordinated optimization of the power system source, grid, load and storage, ensuring the balance of power supply and demand, and improving energy utilization efficiency have become important directions for current power technology research. The present invention proposes a power balancing method for the coordinated power system source, grid, load and storage, aiming to achieve efficient coordination between power generation equipment, load equipment and energy storage equipment through real-time data collection, intelligent prediction and dynamic scheduling, and ensure the stable operation of the power system.

[0034] The core idea of ​​the embodiment provided by the present invention is to build a power management system including a power dispatching platform, power generation equipment, load equipment and energy storage equipment. With the power dispatching platform as the hub, the power generation characteristic parameters of the power generation equipment, the predicted power consumption of the load equipment and the actual storage power of the energy storage equipment are collected in real time, and the power balance dispatching parameters, including the power balance dispatching cycle and the power balance dispatching vector, are dynamically determined by using advanced prediction algorithms and dispatching strategies. These parameters will guide the power output direction and power output of the power generation equipment and the energy storage equipment within the power balance dispatching cycle, thereby achieving the supply and demand balance of the power system.

[0035] The main innovative features of the embodiments provided by the present invention are as follows: Real-time data collection and intelligent prediction: Power generation equipment can obtain the power generation characteristic parameters in the next preset measurement cycle in real time, such as light intensity curve, ambient temperature curve and light angle curve (for photovoltaic power generation equipment), and use these parameters to accurately predict the power generation. Based on historical power consumption data, load equipment uses time series prediction methods to accurately predict the power consumption in the next preset measurement cycle. Energy storage equipment reports the current actual storage power in real time, providing an important reference for power dispatch.

[0036] Dynamic power balance dispatch: The power dispatch platform dynamically calculates power balance dispatch parameters based on the predicted power generation, actual storage power and predicted power consumption collected in real time. By introducing the comparison between the characteristic ratio (the ratio between the predicted power generation and the predicted power consumption) and the preset safety threshold, the power balance dispatch strategy can be flexibly adjusted. When the characteristic ratio is greater than or equal to the preset safety threshold, the load demand is met first, and the excess power is stored in the energy storage device; when the characteristic ratio is less than the preset safety threshold, the energy storage device is used to supplement the power to ensure that the load demand is met.

[0037] Dynamic update of dispatch cycle: The power dispatch platform dynamically updates the power balance dispatch cycle according to the characteristic ratio to adapt to the real-time changes in the power system. This dynamic adjustment mechanism improves the flexibility and adaptability of power dispatch, helps optimize power resource allocation, and improves system efficiency.

The power generation equipment and energy storage equipment are precisely regulated according to the received power balance dispatching parameters to achieve the reasonable transmission and distribution of electric energy and avoid the occurrence of power surplus or shortage.

[0039] Figure 1FIG. 1 is a flow chart of a method for balancing power in a power system with source, grid, load and storage coordination according to an exemplary embodiment of the present invention. Figure 1 As shown, the power balancing method for power system source-grid-load-storage coordination provided by this embodiment includes: S101. The power dispatching platform broadcasts power balancing dispatching instructions to power generation equipment, load equipment and energy storage equipment.

[0040] The power balancing method for power system source-grid-load-storage coordination provided in this embodiment can be applied to a power management system. The power management system includes: a power dispatching platform and power generation equipment, load equipment and energy storage equipment connected through a power network, and the power generation equipment, load equipment and energy storage equipment are respectively connected to the power dispatching platform in communication.

Based on this data, it uses advanced algorithms and models to formulate a reasonable power balance dispatching plan and send dispatching instructions to related equipment.

[0041] Power generation equipment: Power generation equipment is the energy source of the power system. It can be renewable energy power generation equipment such as photovoltaic power generation equipment, wind power generation equipment, hydropower generation equipment, or traditional thermal power generation equipment.

At the same time, they can also provide power consumption forecast data to the power dispatching platform to provide a basis for power balance dispatching.

[0043] Energy storage equipment: Energy storage equipment is an important component of the power system, used to store electricity when there is an oversupply of electricity and release it when there is an undersupply of electricity. It can respond to the instructions of the power dispatching platform and adjust its charging and discharging status to smooth out the fluctuations in supply and demand of the power system.

[0044] Power network: The power network is not only a transmission channel for electric energy, but also a medium for communication between power generation equipment, load equipment and energy storage equipment. Through the power network, these devices can realize real-time transmission of data and accurate issuance of instructions. In addition, communication protocols and interfaces can be set. In order to ensure smooth communication between devices, a unified communication protocol and interface standard can be adopted in the embodiment of the present invention. The power generation equipment, load equipment and energy storage equipment are equipped with communication modules that meet the standard and can communicate stably and efficiently with the power dispatching platform. During the communication process, the embodiment of the present invention can also take a variety of security measures, such as data encryption, identity authentication, etc., to ensure the confidentiality and integrity of the data. At the same time, by establishing redundant communication paths and fault switching mechanisms, the reliability and stability of the communication system are improved.

[0045] In this step, the power dispatching platform generates power balance dispatching instructions based on the real-time operating status and predicted demand of the power system. The power dispatching platform broadcasts the power balance dispatching instructions to the power generation equipment, load equipment and energy storage equipment through communication connections. The instructions include but are not limited to the requirements, time nodes and parameter settings of power balance dispatching.

[0048] Specifically, the power generation equipment responds to the power balance dispatch instruction and obtains the power generation characteristic parameters within the next preset measurement cycle. These parameters may include light intensity curve (for photovoltaic power generation equipment), ambient temperature curve, light angle curve, etc. The power generation equipment determines the predicted power generation based on the acquired power generation characteristic parameters using the built-in prediction algorithm or model. The power generation equipment sends the predicted power generation data to the power dispatch platform for subsequent calculation of power balance dispatch parameters.

[0049] S103: The power generation equipment obtains the actual current storage power of the energy storage equipment in response to the power balance dispatch instruction.

[0054] Specifically, the load device responds to the power balance dispatch instruction, uses the historical power consumption data and the prediction algorithm to obtain the predicted power consumption within the next preset measurement cycle, and the load device sends the predicted power consumption data to the power dispatch platform.

[0055] In a possible design, the load device determines the predicted power consumption in the next preset measurement cycle according to the power consumption in the current preset measurement cycle, the power consumption in the previous preset measurement cycle, and the predicted power consumption in the previous preset measurement cycle in the historical power consumption of the load device. By comprehensively considering the historical power consumption data of the load device, including the power consumption in the current preset measurement cycle, the power consumption in the previous preset measurement cycle, and the predicted power consumption in the previous preset measurement cycle, the power consumption in the next preset measurement cycle can be predicted more accurately. This prediction method based on historical data makes full use of the time series characteristics of the power consumption of the load device and improves the accuracy and reliability of the prediction. Accurate power consumption prediction data provides an important decision-making basis for the power dispatching platform. The power dispatching platform can formulate more reasonable power balance dispatching parameters based on the predicted power consumption, combined with the predicted power generation of the power generation equipment and the actual storage power of the energy storage equipment. This not only helps to balance the supply and demand relationship of the power system, but also effectively reduce the occurrence of power shortage or surplus, and improve the overall operation efficiency of the power system. In addition, based on accurate power consumption prediction, the load device can operate more stably. The power dispatching platform can adjust the operating status of the load device in advance according to the prediction results to avoid equipment failure or damage caused by insufficient or excessive power supply. At the same time, this also helps to extend the service life of load equipment and reduce maintenance and replacement costs.

The power balance dispatching parameters include the power balance dispatching period and the power balance dispatching vector. The balance dispatching vector is used to determine the power output direction and power output of the power generation equipment and the energy storage equipment within the power balance dispatching period.

[0058] Specifically, the power dispatching platform collects the predicted power generation, actual storage power, and predicted power consumption reported by the power generation equipment, and the load equipment. Based on the collected data, the power dispatching platform uses built-in algorithms or models to calculate the power balance dispatching parameters. These parameters include the power balance dispatching cycle and the power balance dispatching vector. Among them, the power balance dispatching cycle is used to determine the execution time range of the power balance dispatching. The power balance dispatching vector is used to determine the power output direction and power output of the power generation equipment and energy storage equipment within the power balance dispatching cycle.

[0059] If the characteristic ratio between the predicted power generation and the predicted power consumption is greater than or equal to the preset safety threshold, the power dispatching platform will give priority to meeting the load demand and store the excess power in the energy storage device. If the characteristic ratio is less than the preset safety threshold, the power dispatching platform will supplement the power through the energy storage device to ensure that the load demand is met. The power dispatching platform can also dynamically update the power balance dispatching cycle according to the characteristic ratio to adapt to the real-time changes of the power system.

[0060] In this embodiment, a power balancing dispatching instruction is broadcasted to power generation equipment, load equipment and energy storage equipment through a power dispatching platform. Then, the power generation equipment responds to the power balancing dispatching instruction, obtains the power generation characteristic parameters within the next preset measurement cycle, and determines the predicted power generation according to the power generation characteristic parameters, and sends the predicted power generation to the power dispatching platform. The power generation equipment responds to the power balancing dispatching instruction, obtains the current actual storage power of the energy storage device, and sends the actual storage power to the power dispatching platform. The load equipment responds to the power balancing dispatching instruction, obtains the predicted power consumption within the next preset measurement cycle, and sends the predicted power consumption to the power dispatching platform, so that the power dispatching platform determines the power balancing dispatching parameters according to the predicted power generation, the actual storage power and the predicted power consumption, wherein the power balancing dispatching parameters include a power balancing dispatching cycle and a power balancing dispatching vector, and the balancing dispatching vector is used to determine the power output direction and power output of the power generation equipment and the energy storage equipment within the power balancing dispatching cycle, and then adjusts the power balancing dispatching parameters according to real-time data, which can more effectively utilize the resources of the power generation equipment and the energy storage equipment, which can not only reduce energy waste, but also improve the resource utilization efficiency of the entire power system.

[0061] Figure 2FIG. 1 is a flow chart of a power balancing method for power system source-grid-load-storage coordination according to another exemplary embodiment of the present invention. Figure 2 As shown, the power balancing method for power system source-grid-load-storage coordination provided by this embodiment includes: S201. The power dispatching platform broadcasts power balancing dispatching instructions to power generation equipment, load equipment and energy storage equipment.

[0062] In this step, the power dispatching platform generates power balance dispatching instructions based on the real-time operating status and predicted demand of the power system. The power dispatching platform broadcasts the power balance dispatching instructions to the power generation equipment, load equipment and energy storage equipment through communication connections. The instructions include but are not limited to the requirements, time nodes and parameter settings of power balance dispatching.

[0063] S202: The power generation equipment obtains power generation characteristic parameters within a next preset measurement period in response to the power balance scheduling instruction, and determines the predicted power generation according to the power generation characteristic parameters.

[0064] In this step, the power generation equipment responds to the power balance scheduling instruction, obtains the power generation characteristic parameters within the next preset measurement cycle, determines the predicted power generation based on the power generation characteristic parameters, and sends the predicted power generation to the power scheduling platform.

[0065] It is worth noting that if the power generation equipment is a photovoltaic power generation equipment, the power generation equipment uses Formula 1 and determines the predicted power generation according to the power generation characteristic parameters. Formula 1 is: in, To predict power generation, is the starting time of the next preset measurement cycle, is the end time of the next preset measurement cycle, is the calibrated photoelectric conversion coefficient of photovoltaic power generation equipment, The light intensity curve for the next preset measurement cycle, is the maximum light receiving area of ​​the photovoltaic power generation equipment, is the preset temperature attenuation coefficient, The ambient temperature curve for the next preset measurement cycle, To calibrate the reference ambient temperature, The illumination angle curve for the next preset measurement cycle, is the preset angle adjustment coefficient, To calibrate the lighting angle.

[0066] In the above scheme, by comprehensively considering multiple factors such as light intensity, ambient temperature and light angle, and introducing corresponding adjustment coefficients, Formula 1 can more accurately reflect the power generation characteristics of photovoltaic power generation equipment in actual operation, thereby improving the accuracy of predicted power generation. Since photovoltaic power generation is greatly affected by natural environmental factors, the use of Formula 1 for prediction can better adapt to different weather conditions and seasonal changes, enabling the power dispatching platform to formulate a more reasonable power balance dispatching strategy. Accurate power generation prediction helps the power dispatching platform to more reasonably allocate the resources of power generation equipment and energy storage equipment. When the power generation is predicted to be sufficient, photovoltaic power generation equipment can be used for power supply first to reduce dependence on traditional energy; when the power generation is predicted to be insufficient, the charging and discharging plan of the energy storage equipment can be adjusted in advance to ensure the stable operation of the power system. By obtaining and predicting photovoltaic power generation in real time, the power dispatching platform can more timely discover the imbalance between supply and demand in the power system and take corresponding dispatching measures to adjust it, thereby enhancing the stability and reliability of the power system.

[0067] In other words, the above formula 1 comprehensively considers multiple key factors that affect photovoltaic power generation, including light intensity, ambient temperature and light angle. By incorporating these factors into the calculation model, the actual power generation characteristics of photovoltaic power generation equipment can be more comprehensively reflected. The introduction of parameters such as calibrated photoelectric conversion coefficient, preset temperature attenuation coefficient, calibrated reference ambient temperature, preset angle adjustment coefficient and calibrated light angle further improves the precision and accuracy of the prediction. These parameters are based on the physical characteristics and historical operation data of photovoltaic power generation equipment, and can more accurately describe the changes in photovoltaic power generation under different conditions. In addition, since formula 1 can calculate and predict photovoltaic power generation in real time, the power dispatching platform can quickly adjust the power balance dispatching strategy according to the latest prediction results. This flexibility helps the power system better respond to emergencies and demand changes and ensure supply and demand balance. By updating the predicted power generation in real time, the power dispatching platform can more accurately control the operating status of power generation equipment and energy storage equipment, optimize resource allocation, and improve the overall operating efficiency of the power system. Accurate power generation prediction helps the power dispatching platform to arrange the work plan of photovoltaic power generation equipment more reasonably and reduce ineffective operation and energy waste. By optimizing the power balance dispatching strategy, it is also possible to reduce the loss during the transmission process of the power grid, further improve the energy utilization efficiency, and promote the realization of energy conservation and emission reduction goals. In addition, accurate power generation forecasts help the power dispatching platform better meet the power needs of users and reduce the occurrence of power shortages or surpluses. This helps to improve the user's power experience and enhance the user's trust and satisfaction with the power system. By achieving the balance of supply and demand and stable operation of the power system, it is also possible to reduce the risk of power outages and equipment failure rates, and further improve the reliability and safety of users' power use.

[0068] S203: The power generation equipment obtains the actual current storage power of the energy storage equipment in response to the power balance dispatch instruction.

[0069] In this step, the power generation equipment responds to the power balance dispatch instruction, obtains the current actual storage power of the energy storage device, and sends the actual storage power to the power dispatch platform.

[0070] Specifically, the power generation equipment also responds to the power balance dispatch instruction to obtain the actual current storage power of the energy storage equipment, and sends the actual storage power data to the power dispatch platform to reflect the current state of the energy storage equipment.

[0071] S204: The load device obtains the predicted power consumption within the next preset measurement period in response to the power balance scheduling instruction.

[0072] In this step, the load device responds to the power balance dispatch instruction, obtains the predicted power consumption within the next preset measurement cycle, and sends the predicted power consumption to the power dispatch platform.

[0073] Specifically, the load device responds to the power balance dispatch instruction, uses the historical power consumption data and the prediction algorithm to obtain the predicted power consumption within the next preset measurement cycle, and the load device sends the predicted power consumption data to the power dispatch platform.

[0074] It is worth noting that the load device uses Formula 2 and determines the predicted power consumption in the next preset measurement period based on the historical power consumption of the load device. Formula 2 is: in, The predicted power consumption in the next preset measurement cycle. To preset the speed adjustment parameters, The power consumption in the current preset measurement cycle in the historical power consumption. The power consumption in the last preset measurement cycle in the historical power consumption. It is the predicted power consumption in the last preset measurement cycle.

[0075] It is worth noting that the above formula 2 can more accurately predict the power consumption in the next preset measurement cycle by comprehensively considering the historical power consumption data of the load equipment, including the power consumption in the current preset measurement cycle, the power consumption in the previous preset measurement cycle, and the predicted power consumption in the previous preset measurement cycle. The introduction of the preset change speed adjustment parameter enables the prediction model to dynamically adjust the prediction results according to the change trend of historical data, further improving the accuracy and reliability of the prediction.

[0076] Since Formula 2 can update the predicted power consumption in real time, the power dispatching platform can quickly adjust the power balance dispatching strategy based on the latest prediction results to adapt to changes in the power consumption of load equipment. This adaptability helps the power system better cope with demand fluctuations and emergencies, ensure supply and demand balance, and improve the stability and reliability of the system. In addition, accurate power consumption forecasts provide an important decision-making basis for the power dispatching platform, enabling it to more reasonably arrange the operating status of power generation equipment and energy storage equipment and optimize the configuration of power resources. By achieving the optimal configuration of power resources, energy waste can be reduced, the resource utilization efficiency of the entire power system can be improved, and operating costs can be reduced.

[0077] In addition, the application of Formula 2 enables the power dispatching platform to better meet the power demand of users and reduce the occurrence of power shortages or surpluses. By achieving a balance between supply and demand in the power system, the reliability and safety of users' power consumption can be improved, and the user's power consumption experience can be enhanced. By realizing the intelligent and automated management of the power system, the operating efficiency and service level of the power system can be improved, providing strong support for the construction of smart grids.

[0078] S205. The power dispatching platform determines power balance dispatching parameters according to the predicted power generation, actual stored power and predicted power consumption.

[0079] In this step, the power dispatching platform determines the power balance dispatching parameters according to the predicted power generation, actual stored power and predicted power consumption. The power balance dispatching parameters include the power balance dispatching period and the power balance dispatching vector. The balance dispatching vector is used to determine the power output direction and power output of the power generation equipment and the energy storage equipment within the power balance dispatching period.

[0080] In one case, if the power dispatching platform determines that the characteristic ratio between the predicted power generation and the predicted power consumption is greater than or equal to the preset safety threshold, Formula 3 is used to determine the power balance dispatching period based on the predicted power generation, the actual stored power, and the predicted power consumption, where Formula 3 is: in, is the power balance dispatch cycle, To predict power generation, To predict power consumption, is the maximum storage capacity of the energy storage device, is the actual storage capacity of the energy storage device at present, To preset the calibration scheduling cycle; The power dispatching platform determines a first balance dispatching vector and a second balance dispatching vector based on the predicted power generation and the predicted power consumption. The first balance dispatching vector is used to indicate that the power generation equipment outputs the electric energy of the predicted power consumption to the load equipment within the power balance dispatching period, and the second balance dispatching vector is used to indicate that the power generation equipment outputs the electric energy of the difference between the predicted power generation and the predicted power consumption to the energy storage equipment within the power balance dispatching period. The power balance dispatching vector includes the first balance dispatching vector and the second balance dispatching vector.

[0081] It is worth noting that Formula 3 can dynamically calculate the power balance dispatch cycle by comprehensively considering the predicted power generation, predicted power consumption, the maximum storage power of the energy storage device, the current actual storage power of the energy storage device, and the preset calibration dispatch cycle. This dynamic adjustment mechanism enables the power dispatch platform to flexibly arrange power production and consumption according to the real-time operation status of the power system, thereby optimizing the configuration of power resources. The power balance dispatch cycle determined by Formula 3 can ensure that the predicted power generation of the power generation equipment can meet the predicted power consumption of the load equipment while providing the necessary charging time for the energy storage equipment to keep the energy storage equipment sufficient. This arrangement helps to avoid the imbalance of power supply and demand, thereby enhancing the stability of the power system and reducing the occurrence of power shortages or surpluses. In addition, Formula 3 uses the maximum storage power and the current actual storage power of the energy storage device as important parameters for calculating the power balance dispatch cycle to ensure that the energy storage device can be charged or discharged at the appropriate time. This optimization strategy helps to improve the utilization rate of energy storage equipment, reduce energy waste, and improve the resource utilization efficiency of the entire power system. In addition, the preset calibration dispatch cycle in formula 3 provides a reference benchmark for the power dispatch platform, allowing dispatchers to adjust the dispatch cycle when necessary based on the actual operation of the power system. This flexibility helps the power dispatch platform better respond to emergencies and demand fluctuations and ensure the stable operation of the power system.

[0082] Furthermore, after using Formula 3 and determining the power balance dispatching period according to the predicted power generation, the actual stored power and the predicted power consumption, it also includes: The power dispatching platform uses formula 4 and updates the power balance dispatching cycle according to the characteristic ratio. Formula 4 is: in, is the characteristic ratio, is the dynamic adjustment factor of the power balance dispatch cycle, To preset the grid stability factor, is the preset first weight value, is a preset second weight value.

[0083] It is worth noting that Formula 5 dynamically adjusts the power balance dispatching cycle by introducing a characteristic ratio, that is, the ratio between the predicted power generation and the predicted power consumption. This adjustment method enables the power dispatching platform to arrange power production and consumption more accurately according to the real-time supply and demand conditions of the power system, thereby improving the accuracy and flexibility of dispatching. The dynamic adjustment factor of the power balance dispatching cycle in Formula 5 comprehensively considers multiple factors, including a preset grid stability factor, a preset first weight value, and a preset second weight value. Through the setting and adjustment of these parameters, the power dispatching platform can more effectively respond to fluctuations and changes in the power system, thereby enhancing the stability of the power system. Through the update of the power balance dispatching cycle by Formula 5, the power dispatching platform can allocate power resources more reasonably. When the predicted power generation is sufficient, the dispatching cycle can be extended to allow the power generation equipment more time for maintenance and repair; when the predicted power generation is insufficient, the dispatching cycle can be shortened to ensure the timeliness and stability of power supply. In addition, the current actual storage capacity of the energy storage device and the maximum storage capacity of the energy storage device in Formula 5 are important parameters for calculating the dynamic adjustment factor of the power balance dispatching cycle, which helps to optimize the charging and discharging strategy of the energy storage device. Through reasonable scheduling cycle arrangement, it can ensure that the energy storage equipment is charged or discharged at the appropriate time, thereby improving the utilization rate of the energy storage equipment. In addition, the various parameters in Formula 5 can also be flexibly set and adjusted according to the actual situation of the power system, so that the power dispatching platform can better respond to the power supply and demand conditions in different scenarios, thereby ensuring the stable operation and sustainable development of the power system.

[0084] In another case, if the power dispatching platform determines that the characteristic ratio between the predicted power generation and the predicted power consumption is less than the preset safety threshold, Formula 5 is used to determine the power balance dispatching period based on the predicted power generation, the actual stored power, and the predicted power consumption, where Formula 5 is: The power dispatching platform determines a third balance dispatching vector and a fourth balance dispatching vector based on the predicted power generation and the predicted power consumption. The third balance dispatching vector is used to indicate that the power generation equipment outputs electric energy of the predicted power consumption to the load equipment within the power balance dispatching period. The fourth balance dispatching vector is used to indicate that the energy storage equipment outputs electric energy of the absolute value of the difference between the predicted power generation and the predicted power consumption to the load equipment within the power balance dispatching period. The power balance dispatching vector includes the third balance dispatching vector and the fourth balance dispatching vector.

[0085] It is worth noting that when the characteristic ratio between the predicted power generation and the predicted power consumption is less than the preset safety threshold, it means that the predicted power generation of the power generation equipment cannot meet the predicted power consumption of the load equipment. At this time, Formula 4 dynamically calculates the power balance scheduling cycle by considering the current actual storage power of the energy storage device and the absolute value of the difference between the predicted power generation and the predicted power consumption. This dynamic adaptability ensures that the scheduling cycle can be flexibly adjusted according to the real-time supply and demand conditions of the power system, thereby improving the effectiveness and response speed of scheduling. Through the scheduling cycle calculated by Formula 4, the power dispatching platform can more reasonably arrange the working hours of power generation equipment and energy storage equipment. In the case of insufficient power generation, the scheduling cycle may be shortened to ensure that the energy storage equipment can replenish electricity in time to meet the load demand. This resource optimization helps to reduce the operating cost of the power system and improve energy utilization efficiency. After determining the power balance scheduling cycle, the power dispatching platform determines the third balance scheduling vector and the fourth balance scheduling vector based on the predicted power generation and predicted power consumption. The third balance scheduling vector ensures that the power generation equipment outputs the predicted power consumption to the load equipment within the scheduling cycle to meet the basic load demand. The fourth balancing dispatch vector instructs the energy storage device to output additional electric energy to the load device when necessary to make up for the shortage of power generation. This precise control helps to achieve the balance between supply and demand of the power system and ensure the stability and reliability of power supply. Through the joint action of the third balancing dispatch vector and the fourth balancing dispatch vector, the power generation equipment and the energy storage device can work together. When the power generation is sufficient, the energy storage device can store excess electric energy; when the power generation is insufficient, the energy storage device can release the stored electric energy to supplement the power supply. This equipment coordination mechanism helps to improve the overall operation efficiency of the power system and reduce operation and maintenance costs. In addition, when the power generation cannot meet the load demand, the energy storage device can replenish electric energy in time through the guidance of the fourth balancing dispatch vector, thereby effectively alleviating the risk of power shortage. This risk mitigation mechanism helps to ensure the stable operation of the power system and avoid serious consequences such as system paralysis or large-scale power outages caused by power shortages.

[0086] For example, in emergencies or extreme weather conditions, the supply and demand of the power system may change dramatically. At this time, through the combined effect of Formula 4 and the balanced dispatch vector, the power dispatch platform can quickly adjust the dispatch strategy to ensure the emergency response capability of the power system. This emergency response mechanism helps to improve the safety and reliability of the power system and ensure the electricity demand of users.

[0087] Furthermore, after using Formula 4 and determining the power balance dispatching period according to the predicted power generation, the actual stored power and the predicted power consumption, it also includes: The power dispatching platform uses Formula 6 and updates the power balance dispatching cycle according to the characteristic ratio. Formula 6 is: in, is the characteristic ratio, is the dynamic adjustment factor of the power balance dispatch cycle, To preset the grid stability factor, is the preset first weight value, is a preset second weight value.

[0088] It is worth noting that Formula 6 introduces multiple parameters such as characteristic ratio, dynamic adjustment factor of power balance dispatching cycle, preset grid stability factor, preset first weight value and preset second weight value, so that the power dispatching platform can dynamically adjust the dispatching cycle according to the real-time supply and demand situation of the power system. This flexibility helps the power dispatching platform to better cope with emergencies and supply and demand changes in the power system and ensure the stability and reliability of power supply. By comprehensively considering the predicted power generation, predicted power consumption, the current actual storage power of the energy storage device and the maximum storage power of the energy storage device, Formula 6 can calculate a more reasonable power balance dispatching cycle. This helps the power dispatching platform to more accurately arrange the work of power generation equipment and energy storage equipment, optimize the configuration of power resources, and improve energy utilization efficiency. The dynamic adjustment factor in Formula 6 is adjusted according to the characteristic ratio, the preset first weight value and the preset second weight value, which means that the dispatching cycle will be finely adjusted according to the real-time supply and demand situation of the power system and the state of the energy storage device. This accuracy helps to reduce the situation of power surplus or shortage and ensure the balance of supply and demand of the power system. By continuously updating the power balance dispatch cycle, the power dispatch platform can better coordinate the work of power generation equipment and energy storage equipment to avoid equipment overload or idleness, thereby improving the stability of the entire power system. In addition, the preset grid stability factor in Formula 6 also helps to ensure the stability of the power system during the dispatch process. When the power system faces an emergency or an imbalance between supply and demand, Formula 6 can quickly calculate the new power balance dispatch cycle and guide the power generation equipment and energy storage equipment to make corresponding adjustments. This rapid response capability helps the power dispatch platform better respond to emergencies in the power system and ensure the continuity and stability of power supply.

[0089] S206. The power dispatching platform sends the power balance dispatching parameters to the power generation equipment and the energy storage equipment.

[0090] In this step, the power dispatching platform sends the power balance dispatching parameters to the power generation equipment and the energy storage equipment, so that the power generation equipment and / or the energy storage equipment transfer electric energy according to the power balance dispatching parameters.

[0091] The power dispatching platform receives the predicted power generation sent by the power generation equipment, the actual storage power sent by the energy storage equipment, and the predicted power consumption sent by the load equipment, and comprehensively considers the real-time supply and demand status of the power system, the status of the energy storage equipment, and the power generation capacity of the power generation equipment to determine reasonable power balance dispatching parameters. These parameters include but are not limited to the power balance dispatching cycle, power balance dispatching vector, etc., which together form the basis for the power dispatching platform to accurately control the power system.

[0092] After determining the power balance dispatch parameters, the power dispatch platform sends these parameters to the power generation equipment and energy storage equipment in real time through the communication network. The realization of this step depends on the perfect communication infrastructure and efficient communication protocol in the power management system to ensure that the parameters can be accurately and quickly transmitted to the target equipment.

[0093] The power balance dispatch parameters received by the power generation equipment will guide the power generation equipment to output the corresponding amount of electric energy to the load equipment and energy storage equipment within the power balance dispatch cycle. The power generation equipment adjusts its power generation plan according to the parameters to ensure that the output electric energy matches the dispatch requirements.

[0094] For energy storage devices, the received power balance scheduling parameters will determine their charging or discharging status within the power balance scheduling cycle. When the predicted power generation of the power generation equipment exceeds the predicted power consumption of the load equipment, the energy storage equipment will receive the excess power for storage; and when the predicted power generation of the power generation equipment cannot meet the predicted power consumption of the load equipment, the energy storage equipment will release the stored power for supplementation.

[0095] After receiving the power balance dispatch parameters, the power generation equipment and energy storage equipment perform accurate power transmission according to the parameters. The realization of this step depends on the efficient power transmission and distribution network in the power system, as well as the power output and storage capacity of the power generation equipment and energy storage equipment themselves.

[0096] The power generation equipment adjusts its power output direction and output amount according to the power balance dispatch vector in the power balance dispatch parameter to ensure stable power supply to the load equipment and energy storage equipment.

[0097] The energy storage device performs charging or discharging operations according to the instructions in the power balance scheduling parameters to balance the supply and demand relationship in the power system. During the charging process, the energy storage device receives the excess power output by the power generation equipment; during the discharging process, the energy storage device provides the required power to the load equipment.

[0098] During the power transmission process, the power dispatching platform dynamically adjusts the power balance dispatching parameters by monitoring the operating status of the power system and the power output and storage of power generation equipment and energy storage equipment in real time. The realization of this step depends on the perfect monitoring system and efficient adjustment mechanism in the power management system to ensure that the power system can always operate in a stable and efficient state.

[0099] In the above scheme, after determining the power balance dispatch parameters, the power dispatch platform promptly sends these parameters to the power generation equipment and energy storage equipment, ensuring the accuracy of power system regulation. The power generation equipment and energy storage equipment can accurately adjust their power output or storage status according to the received power balance dispatch parameters, thereby achieving the supply and demand balance of the power system. This precise regulation helps to avoid power surplus or shortage and ensure the stable operation of the power system.

[0100] By sending power balance dispatch parameters through the power dispatch platform, power generation equipment and energy storage equipment can transfer power according to actual needs, thereby improving the utilization efficiency of power resources. During peak power demand periods, power generation equipment can increase power output, and energy storage equipment can release stored power when necessary to meet load demand. During low power demand periods, power generation equipment can reduce power output, and energy storage equipment can store excess power for emergency use. This flexible power transmission method helps reduce the operating cost of the power system and improve overall economic benefits.

[0101] In addition, the power dispatching platform sends power balance dispatching parameters to power generation equipment and energy storage equipment, allowing these devices to quickly respond to changes in the power system. When power supply and demand are unbalanced or emergencies occur, power generation equipment and energy storage equipment can quickly adjust according to the power balance dispatching parameters to ensure the stability and reliability of the power system. This fast response speed helps reduce the risk of power system failures and improve users' power experience.
