In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0040] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0041] like Figure 1As shown, the present invention provides an intelligent photovoltaic storage microgrid management method, which is applied to a communication base station. The intelligent photovoltaic storage microgrid management method includes:

[0042] In step S11, the power load demand of the communication base station is obtained in real time;

[0043] In step S12, the power generation of the wind and solar power generation device and the charge state of the energy storage device of the communication base station are monitored in real time;

[0044] In step S13, the charging and discharging of the wind-solar-storage microgrid is controlled according to the power load demand of the communication base station, the power generation of the wind-solar power generation device and the charge state of the energy storage device to ensure that the wind-solar power generation is preferentially used to meet the power demand of the communication base station.

[0045] In one embodiment, based on the power demand of the communication base station and the cooperation between wind and solar power generation and energy storage devices, the stability and sustainability of the power supply of the communication base station are guaranteed by optimizing the energy utilization rate. The power load demand of the communication base station is obtained, the power generation of the wind and solar power generation device is monitored, and the charge state of the energy storage device is monitored. Through the real-time data collection of the above three aspects, the charging and discharging strategy of the wind, solar and storage microgrid can be adjusted according to the power load demand of the base station, so as to ensure that wind and solar power generation is used preferentially to meet the power demand of the base station. By real-time monitoring of the power demand of the base station and the actual output of wind and solar power generation, it is decided whether to dispatch the energy storage device or directly use the power of the power grid. By optimizing the use of wind and solar power generation, it is possible to maximize the use of renewable energy and reduce dependence on traditional power grids while ensuring the power demand of the base station. The energy storage device makes decisions based on various data (such as power load, power generation, charge state, etc.) obtained in real time, and adjusts the charging and discharging strategy to achieve the best energy utilization effect.

[0046] Adjust the charging and discharging strategies of the energy storage device during different power periods (off-peak and off-peak periods). Off-peak periods are periods when the power grid electricity price is relatively low. The energy storage device is charged at this time, and the advantage of the electricity price is used to store energy. During peak periods, the power grid electricity price is relatively high. It is necessary to give priority to the use of wind and solar power generation, followed by energy storage batteries, and finally grid electricity, based on the wind and solar power generation situation, base station load demand, and the current power of the energy storage device. The priority order of electricity use is the power generation of the wind and solar power generation device of the communication base station, the power of the energy storage device, and the power of the grid, ensuring that when the power generation is sufficient, the base station gives priority to the use of wind and solar power generation, and when the wind and solar power generation is insufficient, the power in the energy storage device is called upon, and finally the power of the grid is relied upon, thereby reducing the grid load and operating costs.

[0047] The charging and discharging strategy of the energy storage device should be adjusted according to the real-time monitored state of charge, especially in combination with the feedback information of the battery management system (BMS). BMS can provide the real-time battery status of the energy storage device to help the energy storage device decide whether it needs to be charged or discharged. When the wind and solar power generation is sufficient and the energy storage device is not fully charged, the excess wind and solar power generation should be stored in the energy storage device, which effectively ensures the maximum power utilization of the energy storage device and avoids the waste of wind and solar power generation resources. In the case of insufficient wind and solar power generation, the energy storage device can provide supplementary power to ensure that the power supply of the base station is not affected.

[0048] The function of dynamically adjusting the charging and discharging strategy of the energy storage device according to weather conditions, wind and solar power generation, and base station load demand introduces the impact of the external environment (weather) on the energy storage management strategy, reflecting the adaptive characteristics of smart microgrid management. On sunny days or with strong winds, wind and solar power generation is usually high. Communication base stations should give priority to storing this excess electricity, which will help improve the utilization rate of wind and solar power generation and avoid energy waste. In unfavorable weather conditions (such as cloudy days or low wind speeds), the discharge priority of the energy storage device is increased to supplement the shortage of wind and solar power generation, thereby ensuring the stability of the base station's power supply.

[0049] The integration with the power market reflects efficient resource utilization. By aggregating the power resources of multiple communication base stations to form a virtual power plant and supplying power to the power grid, the dispatching capability and flexibility of the overall power system are enhanced. In the power market, virtual power plants can participate in peak load regulation or valley filling. By rationally dispatching the charging and discharging strategies of energy storage devices and optimizing the allocation of power resources, it can not only reduce power costs, but also improve the overall stability of the power grid and avoid power waste.

[0050] Real-time weather data is used to predict wind and solar power generation, analyze base station power demand and grid load, and thus participate in the power market demand response. This emphasizes the flexibility and foresight of the smart wind, solar, and energy storage microgrid system, and can adjust the charging and discharging strategy through real-time data prediction. By analyzing weather data and base station power demand, countermeasures can be taken in advance to reduce grid load fluctuations, thereby improving the stability and reliability of grid operation.

[0051] Starting from the acquisition and monitoring of electricity demand, it then introduces multiple aspects such as intelligent control, charging and discharging strategies, dynamic adjustment, weather influence, and electricity market participation. It can not only improve the utilization efficiency of wind and solar power generation and energy storage devices and reduce the electricity cost of base stations, but also participate in electricity market transactions through virtual power plants, optimize the allocation of electricity resources, and ultimately achieve the stability, sustainability and economy of base station power supply, thus forming a complete and efficient intelligent wind, solar and energy storage microgrid management method.
