For example, in the absence of sufficient sunlight, photovoltaic systems cannot generate enough electricity to meet real-time demand, while energy storage systems can store energy when photovoltaic systems produce excess electricity and release it when needed to help balance supply and demand. Current technology lacks a comprehensive strategy to coordinate the dynamic interaction between the two.

[0015] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0016] Embodiment 1, as Figure 1 As shown, the present application provides a power dispatching method for photovoltaic and energy storage coordinated control, the method comprising:

[0017] Construct a photovoltaic communication base station architecture, wherein the photovoltaic communication base station architecture includes a mains module, a photovoltaic module, a lithium battery module, a backup power module, a communication load module and a DC bus module.

[0018] Specifically, the construction of the photovoltaic storage communication base station aims to optimize the integration and coordination of photovoltaic power generation and battery energy storage systems to improve energy utilization efficiency and enhance the stability of the power system. The photovoltaic storage communication base station architecture includes a mains module, a photovoltaic module, a lithium battery module, a backup power module, a communication load module and a DC bus module. First, the mains module is responsible for accessing the traditional power grid, providing the system with basic power supply guarantee and emergency backup power supply, and providing necessary power support when photovoltaic power generation is insufficient to support the load or encounters a system failure. The photovoltaic module is the core of the architecture. It directly converts solar energy into electrical energy through the installed photovoltaic panels for daily power supply. As the main facility for power storage, the lithium battery module is responsible for storing electrical energy when photovoltaic power generation is in excess, and releasing electrical energy when power demand peaks or photovoltaic power generation is insufficient, to ensure the continuity and stability of power supply. The backup power module usually includes lead-acid batteries or other types of energy storage devices, which are used as a second-level backup power supply to further ensure the safety of system operation under extreme conditions. The communication load module refers to the load connected to various communication devices, which require stable and reliable power support to ensure the normal operation of communication services. The DC bus module serves as the link for power transmission between modules, and is responsible for the unified distribution of power from the mains, photovoltaic and lithium battery modules, as well as regulating and optimizing the distribution and use of power. This design not only improves the utilization efficiency of photovoltaic power generation, but also optimizes power supply through the intelligent power dispatching system, effectively solving the problems of low energy utilization efficiency and inflexible power dispatching.

[0019] Real-time environmental monitoring is performed on the photovoltaic module to obtain photovoltaic environmental information.

[0020] Optional real-time environmental monitoring of PV modules aims to ensure that the PV power generation system can adjust its operating state according to the actual environmental conditions, thereby improving energy conversion efficiency and optimizing power output. The specific implementation steps involve the use of a series of sensors to continuously monitor environmental parameters closely related to PV performance, such as solar radiation intensity, ambient temperature, wind speed and other meteorological conditions that may affect the performance of PV panels. The data collected by these sensors is PV environmental information, which is essential for real-time evaluation of the power generation potential of PV modules.

[0021] Solar radiation intensity sensors accurately measure the intensity of sunlight reaching the surface of the photovoltaic panel, which is the basis for evaluating the energy available for conversion into electricity. Ambient temperature sensors monitor the temperature of the environment in which the photovoltaic panel is located, as high temperatures may reduce the efficiency of the photovoltaic panel. The data provided by the wind speed sensor helps to determine whether the wind cooling effect is sufficient to reduce the operating temperature of the photovoltaic panel, thereby improving its power generation efficiency. By collecting this environmental data in real time, the photovoltaic module can perform data analysis through an integrated management system, which analyzes the data and determines whether the current power generation conditions are ideal.

[0022] If the monitored environmental conditions indicate that the light intensity is high and the temperature is suitable, the photovoltaic module will adjust its operating strategy according to these optimized conditions, such as increasing power output. Conversely, if the environmental information shows conditions that are not conducive to power generation, such as cloudy days or high temperatures, the system can reduce output or shift the focus of operation to energy storage equipment to ensure the stability of the overall energy supply. This dynamic adjustment mechanism based on real-time environmental monitoring enables the photovoltaic system to maintain optimal operating efficiency under various climatic conditions, thereby significantly improving energy utilization efficiency and reducing waste. In addition, the monitoring system can also provide data to support system maintenance and fault prevention, further enhancing the reliability and economy of the system.

[0023] It is determined whether the photovoltaic environment information satisfies a predetermined photovoltaic environment.

[0024] If the photovoltaic environment information meets the predetermined photovoltaic environment, a photovoltaic priority instruction is generated.

[0025] Exemplarily, the evaluation of photovoltaic environmental information and its impact on operating instructions is a key step in achieving energy optimization. This process involves analyzing the data collected from the real-time environmental monitoring system of the photovoltaic module to determine whether the current environmental conditions meet the preset optimal power generation environment standards, which are the predetermined photovoltaic environment. Specifically, the predetermined photovoltaic environment includes a combination of solar radiation intensity, ambient temperature and wind speed within a specific range. These parameter values ​​are determined based on historical data and photovoltaic power generation efficiency research to ensure that the photovoltaic module operates under the most efficient conditions. The system analyzes the collected photovoltaic environmental information through an integrated data processing unit, such as whether the radiation intensity has reached the threshold that allows maximum power output, whether the ambient temperature is in the range where the photovoltaic panel is most efficient, and whether the wind speed is sufficient to effectively reduce the surface temperature of the photovoltaic panel without causing equipment stability problems. This analysis process is carried out through advanced algorithms to ensure that the environmental conditions are evaluated immediately and accurately. If the analysis results confirm that the current environmental information meets all the conditions of the predetermined photovoltaic environment, the system will automatically generate a photovoltaic priority instruction. The photovoltaic priority instruction is an operation command used to adjust the power output priority of the photovoltaic system to ensure that the photovoltaic capacity is maximized under ideal power generation conditions and reduce dependence on energy storage equipment or city power. After generating the photovoltaic priority instruction, the energy flow of each module is adjusted to give priority to meeting the load demand. At the same time, the excess power can be used to charge the energy storage equipment for emergency use. This process not only enhances the ability to respond to environmental changes, but also effectively improves the operating efficiency and economy of the entire power system through the intelligent decision support system. In this way, it can ensure that renewable resources are fully utilized under the best power generation conditions, thereby achieving sustainable energy management.

[0026] Based on the photovoltaic priority instruction, the photovoltaic power of the photovoltaic module is read, and the load power of the communication load module is loaded.

[0027] Furthermore, in order to ensure that the priority and efficiency of photovoltaic power generation are maximized under ideal photovoltaic environment, the monitoring interface of the photovoltaic module is immediately accessed to read the current photovoltaic power after receiving the photovoltaic priority instruction. Photovoltaic power is the amount of electricity generated by the photovoltaic module in a given time. This reading operation is performed through advanced sensors and data processing systems to ensure the real-time and accuracy of the data. Next, the power load required by the communication load module is adjusted according to the photovoltaic power data read. The communication load module contains various communication devices and related support systems, which require a stable power supply to maintain normal operation. When the photovoltaic power is sufficient, the photovoltaic power generated is used to meet the power demand of these loads, thereby reducing the dependence on the mains or energy storage system. In addition, the system also includes a dynamic load manager, which automatically adjusts the energy consumption of the communication load module according to the change of photovoltaic power and optimizes the efficiency of energy use. For example, when the photovoltaic power is higher than a preset threshold, the dynamic load manager can increase the power demand of the load module to make full use of the available photovoltaic power; when the photovoltaic power is not enough to support all the loads, the load power is reduced to ensure the continuous operation of key equipment. Through this series of operations, it is possible to ensure that when the photovoltaic system generates electricity at its highest efficiency, this green energy is utilized to the maximum extent, while reducing energy consumption and operating costs, and improving the energy management efficiency and sustainability of the entire system. This not only enhances the environmental adaptability of the power system, but also provides a more stable and economical power solution for communication facilities.

[0028] Based on the photovoltaic power and the load power, a photovoltaic priority power dispatch decision is made for the communication load module according to the mains module, the photovoltaic module and the lithium battery module to obtain a load power dispatch strategy.

[0029] The communication load module is powered according to the load power dispatching strategy.

[0030] Specifically, once the PV power and load power data have been acquired, the system will use this information to execute power dispatch decisions, giving priority to the power generated by the PV modules to improve overall energy efficiency and reduce reliance on non-renewable energy. First, the system evaluates the real-time power currently obtained from the PV modules (PV power) and compares it with the current power demand of the communication load module (load power). This comparison helps determine whether there is enough PV power to meet the needs of the communication load, or whether additional power needs to be extracted from other power modules (such as mains modules or lithium battery modules).

[0031] In the power dispatch decision process, if the photovoltaic power is sufficient to meet the load power, the system will directly supply power from the photovoltaic module to the communication load module. This not only reduces the dependence on the mains, but also optimizes energy consumption. If the photovoltaic power is not enough to meet all the load requirements, the system starts the lithium battery module to supplement the shortage, thereby maintaining the continuity and stability of energy supply. In this case, the use of the lithium battery module provides a buffer to ensure that the load can still be continuously powered when the photovoltaic power generation is insufficient. In addition, the mains module, as the last backup power source, will only be enabled when both the photovoltaic and lithium battery modules cannot meet the current load or in an emergency. Through this hierarchical power supply method, the system can maximize the use of renewable energy while ensuring a high reliability and efficiency of power supply. Finally, the communication load module is operated according to the above power dispatch strategy. This process involves dynamically allocating the output of various power modules to ensure the best match between power supply and load demand, while optimizing energy costs. This intelligent dispatch not only improves the economy of energy use, but also enhances the system's adaptability to environmental changes, further promoting the realization of sustainable development goals.

[0032] Furthermore, judging whether the photovoltaic environment information satisfies a predetermined photovoltaic environment includes: if the photovoltaic environment information does not satisfy the predetermined photovoltaic environment, generating a peak shaving and valley filling instruction; and based on the peak shaving and valley filling instruction, performing power scheduling on the communication load module according to the AC power module and the lithium battery module.

[0033] In a specific embodiment, when the environmental data monitored by the system does not meet the preset conditions, such as insufficient light or too high temperature, it will be determined that the photovoltaic environment information does not meet the predetermined photovoltaic environment. In this case, a peak-shaving and valley-filling instruction is automatically generated, which is a strategy aimed at optimizing energy use and reducing energy waste. The peak-shaving and valley-filling instruction mainly smoothes the peaks and valleys of power demand by adjusting power consumption and supply, thereby improving energy efficiency and reducing costs. After the instruction is triggered, the system will mobilize non-photovoltaic power sources, namely the mains module and the lithium battery module, to supplement the insufficient power supply and ensure the stable operation of the communication load module. Specifically, the mains module, as a power source connected to the conventional power grid, will provide necessary power supplement when the photovoltaic power is insufficient to support the communication load module. The scheduling strategy of the mains module will be based on the current load situation and electricity price of the power grid, and will give priority to providing power during periods with lower electricity prices or when demand is lower, so as to reduce operating costs. At the same time, the lithium battery module, as an energy storage device, stores energy when photovoltaic power generation is sufficient, and releases energy to support the load when photovoltaic power generation is insufficient. This strategic use of energy storage not only improves energy efficiency, but also helps the system maintain operation when power supply is limited, ensuring the continuity of communication services. By shaving peak loads and filling valleys, energy use can be effectively managed and optimized when photovoltaic power generation conditions are not ideal, ensuring efficient and economical operation of the power system while reducing dependence on conventional power grids and the impact on the environment. The implementation of this strategy significantly improves the flexibility and responsiveness of energy management, providing important support for sustainable energy solutions.

[0034] Furthermore, based on the photovoltaic power and the load power, a photovoltaic priority power dispatching decision is made for the communication load module according to the AC power module, the photovoltaic module and the lithium battery module, and a load power dispatching strategy is obtained, including: judging whether the photovoltaic power is greater than the load power; if the photovoltaic power is greater than the load power, calculating the photovoltaic surplus power according to the photovoltaic power and the load power; making a charging decision for the lithium battery module based on the photovoltaic surplus power to obtain a lithium battery photovoltaic charging plan; based on the load power, making a photovoltaic power supply decision for the communication load module according to the photovoltaic module to generate a load photovoltaic power supply plan; outputting the load power dispatching strategy according to the lithium battery photovoltaic charging plan and the load photovoltaic power supply plan.

[0035] Furthermore, in order to maximize the utilization efficiency of the photovoltaic system and ensure the stable power supply of the communication load module, the photovoltaic power and the load power are compared in real time to determine the optimal energy distribution and energy storage strategy. The power generated by the photovoltaic module (i.e., photovoltaic power) and the power required by the communication load module (i.e., load power) are monitored in real time. The control logic in the system first determines whether the photovoltaic power is greater than the load power. This judgment is achieved through integrated sensors and intelligent algorithms to ensure the accuracy of data and the timeliness of processing. If the photovoltaic power is greater than the load power, this indicates that the photovoltaic system can not only meet the current power demand, but also has additional power for other purposes. In the case where the photovoltaic power is greater than the load power, the system will calculate the photovoltaic surplus power, that is, the difference between the current photovoltaic power generated and the load demand. The key to this step is to accurately calculate the additional power that can be used for storage or other purposes. Based on the calculated photovoltaic surplus power, the system will make charging decisions, especially whether and how to use the surplus power to charge the lithium battery module. This charging decision takes into account the current state, charging capacity and long-term maintenance requirements of the lithium battery module to ensure the maximum efficiency and life of the energy storage equipment. In addition, a load photovoltaic power supply plan needs to be formulated, that is, how to directly power the communication load module based on the real-time output of the photovoltaic module. This power supply strategy ensures that clean energy is used first when the photovoltaic system can meet the load demand, thereby reducing dependence on other energy sources (such as municipal electricity or energy storage). Finally, the integrated lithium battery photovoltaic charging solution and the load photovoltaic power supply solution output a comprehensive load power dispatching strategy, which specifies in detail the operation mode and energy flow of each module under different photovoltaic capacity and load demand conditions to ensure efficient use of energy and reliability of power supply. In this way, not only the efficiency of energy use is improved, but also the economic and environmental benefits of the photovoltaic system are maximized through intelligent scheduling, providing an efficient solution for sustainable energy management.

[0036] Further, judging whether the photovoltaic power is greater than the load power includes: if the photovoltaic power is less than the load power, calculating the photovoltaic gap power according to the photovoltaic power and the load power; obtaining the load power supply time node; if the load power supply time node is in a power supply valley period, generating a mains auxiliary power supply instruction; based on the mains auxiliary power supply instruction and the photovoltaic gap power, making a mains-photovoltaic collaborative power supply decision for the communication load module according to the mains module and the photovoltaic module, and generating the load power dispatching strategy.

[0037] Optionally, it is detected whether the current photovoltaic power is greater than the required load power. If the photovoltaic power is less than the load power, it means that the photovoltaic system cannot independently meet the power demand of the communication load module, and the system then calculates the required additional power, that is, the photovoltaic gap power. The photovoltaic gap power is the difference between the load power and the photovoltaic power, which intuitively reflects the amount of power that needs to be supplemented by other power sources. Subsequently, the current load power supply time node is evaluated, especially whether this time node is in the low period of daily power use. The power valley period usually refers to the period when the power demand is low and the electricity price is cheap, such as at night. If it is confirmed that the current time is in the valley period, a mains auxiliary power supply instruction is generated to supplement the power that photovoltaic cannot provide with the mains. After that, the mains-photovoltaic collaborative power supply decision is further executed based on the mains auxiliary power supply instruction and the calculated photovoltaic gap power. This decision involves how to efficiently combine the mains and photovoltaic power to jointly meet the power demand of the communication load module. The specific operation includes adjusting the power output of the mains and photovoltaic modules to ensure that the power generated by photovoltaics is used first, and dynamically introducing the mains according to the part of photovoltaic capacity that is insufficient, so as to optimize the power use efficiency and reduce costs. The entire decision-making process not only ensures the stability and economy of power supply, but also maximizes the use of renewable energy through intelligent power supply scheduling, reduces dependence on fossil fuels, and thus supports sustainable energy strategies. The implementation of this method, through precise regulation of the synergy of different power sources, ensures that when the photovoltaic system power is insufficient, the stable operation requirements of the communication load can be seamlessly met through the effective supplement of the mains power.

[0038] Furthermore, if the load power supply time node is in the peak power supply period, a lithium battery auxiliary power supply instruction is generated; based on the lithium battery auxiliary power supply instruction and the photovoltaic gap power, a lithium battery-photovoltaic collaborative power supply decision is made for the communication load module according to the lithium battery module and the photovoltaic module, and the load power scheduling strategy is generated.

[0039] Exemplarily, real-time monitoring and judgment of whether the current load power supply time node is in a peak period. The peak period usually refers to the peak period of power demand, when the burden on the power grid is increased and the electricity price is high. During such a period, if the system detects that the photovoltaic power is less than the load power, that is, there is a photovoltaic gap power, the system will automatically trigger the lithium battery auxiliary power supply instruction. This instruction is generated according to a preset algorithm and strategy, with the purpose of mobilizing energy storage resources to supplement the insufficient power supply, thereby reducing dependence on the power grid and optimizing costs. Subsequently, based on the generated lithium battery auxiliary power supply instruction, the lithium battery module is started, and the current output of the photovoltaic module is used to jointly power the communication load module. In this process, the lithium battery module not only provides the required additional power to fill the photovoltaic gap, but also optimizes the power output ratio and time allocation of the two through an intelligent control system to ensure the efficiency and continuity of power supply. Next, the system calculates an optimal power supply strategy based on the output capacity of the lithium battery module and the photovoltaic module and the current power demand, which includes deciding when to use the energy storage of the lithium battery module, when to rely on the direct power generation of the photovoltaic module, and how to adjust the output power of the two to match the actual power consumption of the communication load module. The formulation of this power supply strategy takes into account energy costs, power supply reliability and sustainability of system operation. Ultimately, through this lithium-photovoltaic collaborative power supply decision, not only can the uninterrupted operation of the communication load module be guaranteed during peak power demand periods, but also the maximum efficiency and cost-effectiveness of energy use can be achieved. The implementation of this strategy effectively balances power supply security and economic benefits, and enhances the flexibility and responsiveness of the entire power supply system.

[0040] Furthermore, if the load power supply time node is in a normal power supply period, the remaining power of the lithium battery in the lithium battery module is obtained; based on the remaining power of the lithium battery and the photovoltaic gap power, a collaborative power supply decision is made for the communication load module according to the AC power module, the photovoltaic module and the lithium battery module to obtain the load power scheduling strategy.

[0041] Furthermore, if it is determined that the current time node is in the normal power supply period, the remaining power of the lithium battery module is automatically detected. The normal power supply period usually refers to the period when the overall power demand of the power grid is relatively low and the electricity price is cheaper than usual. The remaining power of the lithium battery module refers to the amount of electric energy currently stored in the lithium battery. This information is crucial for deciding whether and how to use energy storage to supplement the insufficient photovoltaic output. Subsequently, the system calculates the photovoltaic gap power, which is the difference between the total power required by the current communication load and the actual output power of the photovoltaic module. This calculation helps determine how much additional power is needed to meet the load demand in the absence of sufficient photovoltaic power support. Based on the data of the lithium battery remaining power and the photovoltaic gap power, a coordinated power supply decision will be made. This decision involves how to most effectively combine the resources of the mains module, the photovoltaic module and the lithium battery module to jointly meet the power demand of the communication load module. The specific strategy includes: on the basis that the photovoltaic module can provide a certain power, the proportion of the power released by the lithium battery module is determined according to the remaining power of the lithium battery module, and the mains module is enabled as needed to balance the overall power supply. In addition, the power supply strategy will also take into account the electricity price and energy efficiency, give priority to the use of lower-cost power sources, and ensure the energy supply security and environmental sustainability of the system. This method not only ensures the stability and reliability of power supply, but also optimizes energy use, reduces operating costs, and improves the economic efficiency and environmental protection effect of the overall power system. Through this comprehensive power supply decision and scheduling strategy, it ensures that the power demand of the communication load module can be flexibly and efficiently responded to in various power supply periods, achieving maximum energy utilization and cost optimization.

[0042] Furthermore, if the photovoltaic power is equal to the load power, an adaptive power supply decision is made for the communication load module according to the photovoltaic module to generate the load power dispatching strategy.

[0043] Specifically, when it is detected that the power output of the photovoltaic module just meets the power demand of the communication load module, the adaptive power supply strategy formulation process will be triggered. This matching state means that under ideal conditions, the photovoltaic system can independently support the communication load without the intervention of additional power sources. However, considering that the photovoltaic output may be affected by instantaneous environmental changes such as cloud cover, the system needs to be able to cope with sudden changes. The system then starts an adaptive control module, which is responsible for real-time monitoring of the dynamic relationship between photovoltaic output and load demand. If the photovoltaic output suddenly drops, the control module can quickly calculate the required amount of supplementary power and determine the most appropriate supplementary power source. In the case where the photovoltaic power and the load power are completely matched, this module also needs to be in a ready activation state so that it can respond immediately when the photovoltaic power drops slightly. In addition, the adaptive power supply decision also includes setting a sensitivity threshold to determine when to activate a backup power source, such as a lithium battery module or a mains power supply. This threshold is set based on the historical performance data of the photovoltaic system and the importance of the communication load module to ensure the maximum use of renewable resources without sacrificing equipment safety and service quality. The generated load power dispatch strategy will specify in detail the response measures for various potential situations when PV power accurately matches load demand, including continuing to rely on PV power when PV power is stable, using short-term energy storage to supplement when PV power fluctuates slightly, and switching to other power sources when PV power drops significantly. Through this adaptive power supply decision and power dispatch strategy, efficient, flexible and safe power management can be achieved between the PV system and the communication load, optimizing energy utilization while ensuring the continuity and reliability of communication services. The implementation of this strategy not only improves the system's adaptability to environmental changes, but also helps promote the wider application of sustainable energy.

[0044] Through the technical solutions of the above-mentioned embodiments, the present application provides a method for power dispatching with coordinated control of photovoltaic and energy storage, which solves the technical problems of insufficient flexibility and responsiveness of coordinated management of existing photovoltaic and energy storage management, resulting in limited energy utilization efficiency, and achieves the technical effect of flexible and coordinated use of photovoltaic power generation and energy storage, reducing dependence on conventional power grids, improving energy utilization efficiency, and effectively realizing peak-valley arbitrage to maximize the benefits of energy storage.
