All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "comprising" and "having," and any variations thereof, as referred to in the embodiments of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
At present, the conventional base station is usually powered by commercial power, but commercial power cannot continuously and efficiently output power, and meanwhile, due to the fact that a certain space distance exists between a hydrogen production place and a hydrogen using place of some hydrogen energy, the economic cost in the hydrogen energy transportation and storage process is increased.
Based on this, embodiments of the present application provide a power control method and apparatus for a base station, and an electronic device, by which the technical problem of low power supply capability of a power supply system of the base station can be alleviated.
Embodiments of the present application are further described below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a power control method of a base station according to an embodiment of the present disclosure. The method is applied to a power supply control system, the power supply control system is respectively communicated with a wind power generation system, a photovoltaic power generation system, a fuel cell power generation system and an energy storage battery, the wind power generation system, the photovoltaic power generation system and the fuel cell power generation system are used for providing electric energy for the energy storage battery, and the energy storage battery is used for providing electric energy for a base station. As shown in fig. 1, the method includes:
and step S110, acquiring a real-time SOC value of the energy storage battery.
The State Of Charge (SOC) value is a ratio Of a dischargeable remaining capacity to a full Charge capacity Of the battery after the battery is used for a period Of time or left unused for a long time, and is expressed by a common percentage.
For example, as shown in fig. 2 and fig. 3, the power control system is respectively in communication with the wind power generation system, the photovoltaic power generation system, the fuel cell power generation system, and the energy storage battery, wherein the wind power generation system, the photovoltaic power generation system, and the fuel cell power generation system are used for providing electric energy for the energy storage battery, the energy storage battery is used for providing electric energy for the base station, the system can obtain a real-time SOC value (remaining capacity) of the energy storage battery, and meanwhile, the electric energy generated by wind power generation or photovoltaic power generation can charge the energy storage battery through the corresponding control unit, while maintaining the electric energy consumed by the base station.
And step S120, if the real-time SOC value is larger than a first preset SOC value, controlling the fuel cell power generation system to produce and store hydrogen by using the electric energy of the energy storage battery.
Wherein the hydrogen is used to fuel the power generation of the fuel cell power generation system.
For example, as shown in fig. 4, the first preset SOC value is set to 90%, when the real-time SOC value of the energy storage battery is greater than 90%, a part of electric energy generated by wind power and photovoltaic power generation is used to continuously maintain the power consumption of the base station, and another part of electric energy is used to produce hydrogen and store the produced hydrogen, so as to provide clean fuel for the subsequent power generation of the fuel cell stack. If the real-time SOC value reaches 100%, the hydrogen storage tank is filled and the hydrogen production process is stopped, and at the moment, the electric energy generated by wind power and photovoltaic power generation only needs to meet the power supply requirement of the base station.
In the embodiment, the fuel cell power generation system can be controlled to produce and store hydrogen by timely acquiring the real-time SOC value of the energy storage battery, so that the energy power supply system which combines wind energy, light energy and hydrogen energy, namely a plurality of energy modes and is environment-friendly is realized, and the technical problem of low power supply capacity of a base station power supply system is solved.
The above steps are described in detail below.
In some embodiments, the above method further comprises the steps of:
and a), if the real-time SOC value is smaller than a second preset SOC value, controlling the fuel cell power generation system to supply electric energy to the energy storage battery by using fuel.
And the second preset SOC value is smaller than the first preset SOC value.
For example, as shown in fig. 5, a first preset SOC value is set to 90%, and a second preset SOC value is set to 40%. Under the condition of electric energy lag or shortage of wind power and photovoltaic power generation, the real-time SOC value of the energy storage battery is continuously reduced, and when the real-time SOC value is less than 40%, the system controls and starts the fuel cell power generation system to work, so that the energy storage battery is charged, and the base station is powered.
Based on this, the step a) may include the steps of:
step b), if the real-time SOC value is smaller than a second preset SOC value and the electric energy provided by the wind power generation system and the photovoltaic power generation system is smaller than preset electric energy, determining the real-time hydrogen amount stored by the fuel cell power generation system;
and c), if the real-time hydrogen amount is larger than or equal to the preset hydrogen amount, controlling the fuel cell power generation system to provide electric energy for the energy storage battery by using fuel until the real-time SOC value reaches the first preset SOC value or the real-time hydrogen amount is smaller than the preset hydrogen amount.
For example, as shown in fig. 5, the first preset SOC value is set to 90%, and the second preset SOC value is set to 40%. When the control unit of the energy storage battery confirms that the real-time SOC value is less than 40%, and the wind power generation system and the photovoltaic power generation system cannot meet the power supply requirement of the base station (for example, the wind power generation system and the photovoltaic power generation system do not have enough energy sources or are too few), the charging requirement is sent to the power supply control system, the power supply control system sends a corresponding command to control the fuel cell system to work, meanwhile, the real-time hydrogen amount stored in the fuel cell power generation system is determined, and whether the fuel cell system can be started to work or not is judged according to the real-time hydrogen amount, so that the normal operation of the base station is ensured.
In some embodiments, the number of the base stations is multiple, and the step b) further includes the following steps:
and d), if the real-time hydrogen amount is less than or equal to the preset hydrogen amount, controlling the preset unimportant base stations in the plurality of base stations to stop working.
For example, as shown in fig. 6, the remaining 8 base stations surrounding base station No. 0 are spread in a form of a meter, and transmission is performed electrically between the base stations.
For another example, as shown in fig. 5, if the amount of hydrogen stored in the fuel cell power generation system at this time cannot satisfy the start-up condition, that is, the real-time hydrogen amount is less than or equal to the preset hydrogen amount, the power control system will notify the base station control unit to turn off the preset non-important base station to stop working, so as to satisfy the normal working of the remaining important base stations.
The running state of an important or non-important base station can be controlled by determining the real-time hydrogen amount stored by the fuel cell power generation system, and the safety and the environmental protection of the whole system are improved.
In some embodiments, the number of the base stations is multiple, and the method further includes the following steps:
step e), if the real-time SOC value is smaller than a third preset SOC value, closing all the base stations;
and f), when the real-time SOC value is larger than or equal to the fourth preset SOC value, starting a preset important base station in the plurality of base stations.
And the fourth preset SOC value is smaller than the second preset SOC value, and the third preset SOC value is smaller than the fourth preset SOC value.
For example, as shown in fig. 7, a second preset SOC value is set to 40%, a third preset SOC value is set to 30%, and a fourth preset SOC value is set to 35%. When the real-time SOC value of the energy storage battery is smaller than 30%, all base stations are closed until the real-time SOC value is recovered to 35% or more, preset important base stations in the base stations are opened at the moment, and finally the system returns to the working state that the real-time SOC value is 30% < SOC < 40%.
In some embodiments, the number of the base stations is multiple, and the method further includes the following steps:
step g), acquiring power consumption requirements of a plurality of base stations;
and h), determining the sequence of turning on and/or turning off the base stations based on the real-time SOC value and the power consumption requirement.
It should be noted that the power demand of the base station may transmit information to the power control system through the base station control unit, and meanwhile, the power control system may transmit a base station power transmission signal to each base station control unit according to the real-time SOC value and the power demand condition, and the base station control unit determines the sequence of turning on and/or turning off each base station.
Therefore, the starting and/or closing sequence of the base stations can be controlled according to the power requirements of different base stations, the stable work of important base stations is ensured, and the flexibility and the environmental protection performance of the power control system are improved.
In some embodiments, the above method further comprises the steps of:
step i), acquiring working information of a target power generation system;
and j), controlling the power generation operation of the target power generation system according to the working information.
Wherein the target power generation system comprises any one or more of: a wind power generation system, a photovoltaic power generation system, a fuel cell power generation system; the work information includes any one or more of: the generated electric energy, the generated parameter information and the generated working condition.
The wind power generation system sends the power generated by the wind power generation system, the generated parameter information and the operation information related to the generated operation condition to the power supply control system through the wind power generation control unit, and the power supply control system controls the operation state of the wind power generation system.
The photovoltaic power generation system sends the electric energy of photovoltaic power generation, the parameter information of power generation and the working information related to the working condition of power generation to the power supply control system through the photovoltaic power generation control unit, and the power supply control system controls the running state of the photovoltaic power generation system.
The electric energy generated by the fuel cell system through the fuel cell, the parameter information of the power generation and the working information related to the working condition of the power generation are sent to the power supply control system through the fuel cell power generation control unit, and the operating state of the fuel cell power generation system is controlled by the power supply control system.
Therefore, the running states of various target power generation systems can be controlled according to the working information of the target power generation systems, the energy power supply system which combines wind energy, light energy and hydrogen energy, namely various energy modes and is environment-friendly is realized, and the flexibility and the stability of the whole system are improved.
