Background
Solar energy is a renewable energy source, and is effectively converted into chemical energy or electric energy and other energy, so that the use of non-renewable energy sources (such as coal, petroleum, natural gas and the like) is reduced, and the method is one of energy-saving and environment-friendly modes. For example, the solar power generation module can be respectively connected with the energy storage battery module and the load power supply module; the energy storage battery module is electrically connected with the load power supply module.

And under the condition of no solar illumination, the energy storage battery module discharges to supply power for the load power supply module.
At present, the solar power generation module cannot continuously maintain a high output power for two or more power supply objects, because there are times of strong illumination in the daytime and also times of weak illumination. In this way, the power supply strategy of the solar power generation module for at least two power supply objects is as follows: one power supply object is preferentially supplied with power, and the other power supply object is supplied with power when the power supply object has no power supply requirement. For example, the solar power generation module charges the energy storage battery module and supplies power to the load power supply module in the following manner: under the condition that the energy storage battery module is not fully charged, charging the energy storage battery module; after the energy storage battery modules are fully charged, the energy storage battery modules are not charged any more, and then the load power supply modules are independently supplied with power; in this way, in the case where the solar power generation module charges the energy storage battery module, the load cannot be used normally. Or under the condition that the load is not powered off, the power is supplied to the load power supply module; when the load is powered off, the energy storage battery module is charged, and therefore the energy storage battery module can not be fully charged. Furthermore, the output power of the solar power generation module cannot be considered, so that the energy storage battery module has higher energy storage, and the load power supply module outputs higher power supply electric energy for the load.

The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
The application provides a power distribution method, which is applied to a master control device 100. The master device 100 is located in the power distribution system. As shown in fig. 1, in the electric energy distribution system, a main control device 100 is respectively connected to a solar power generation module 101, an energy storage battery module 104, and a load power supply module 105 in a communication manner, and the solar power generation module 101 and the energy storage battery module 104 are respectively electrically connected to the load power supply module 105. The first switch module 102 is connected between the solar power generation module 101 and the energy storage battery module 104. Wherein a second switch module 103 is connected between the solar power generation module 101 and the load power supply module 105. In the case where the first switch module 102 and the second switch module 103 are both in the closed state, the solar power generation module 101 may simultaneously distribute the electric energy to the energy storage battery module 104 and the load power supply module 105. The electric energy distribution method provided by the application comprises the following steps:
s21: the main control device 100 obtains the power output by the solar power generation module 101 and the state of charge value of the energy storage battery module 104.
On the one hand, when there is illumination in the daytime, the power output from the solar power generation module 101 is greater than 0. Accordingly, the main control device 100 can obtain the power output from the solar power generation module 101; on the other hand, the solar power generation module 101 includes a power management unit for detecting a state of charge value of a battery and the battery. In this manner, the master device 100 may obtain the state of charge value of the battery from the power management module.
S22: the main control device 100 determines whether the state of charge value belongs to the first state of charge interval and the output power is greater than the minimum required power of the load power supply module 105, and if so, performs S23.
The first state of charge interval may be [0%,100% ], or may be [10%, 90% ], or the like, and is not limited thereto. In addition, the minimum required power of the load power supply module 105 refers to the minimum power at which the load 106 can be operated. For example, the minimum required power may be different for different classes of loads 106. For example, the minimum required power may be 2kw, 4kw, 5kw, etc., which is not limited herein.
S23: the main control device 100 determines the value of the power supply power output by the load power supply module 105 and the value of the charging power for charging the energy storage battery module 104 according to the output power and the rated power of the load power supply module 105.
Specifically, the specific implementation of S23 is not limited to the following three cases:
first kind: if the output power satisfies a.ltoreq.P1-a and P.ltoreq.P 1, the charging power charged to the energy storage battery module 104 is determined to have a value a, and the power supplied from the load power supply module 105 is determined to have a value P1-a. Where P1 is the output power, P is the rated power of the load power supply module 105, and a is the minimum required power of the load power supply module 105.
It can be appreciated that, in the case where the output power satisfies a+.p1-a and p1+.p, since P1+.p, the power supply power having the value of the rated power P cannot be allocated to the load power supply module 105, so that the load 106 is in the optimum operation state. Because a is less than or equal to P1-a, the power supply power of P1-a can be distributed to the load power supply module 105, and the power supply power of P1-a can drive the load 106 to operate normally. In addition, the charging power a is used to charge the energy storage battery module 104, so that the energy storage battery module 104 can be continuously charged in a charging period (a period of time with sunlight) to obtain higher energy storage.
Second, if the output power satisfies p2+p > P1> P, the charging power charged to the energy storage battery module 104 is determined to be P1-P, and the power supplied from the load power supply module 105 is determined to be P. Where P1 is the output power, P is the rated power of the load power supply module 105, P2 is the maximum allowable charging power of the energy storage battery module 104, and when the charging power of the energy storage battery module 104 exceeds P2, the energy storage battery module 104 is damaged.
It can be appreciated that, when the output power satisfies p2+p > P1> P, since P1> P, it can be determined that the value of the power supplied output by the load power supply module 105 is the rated power P, and the load 106 can be in the optimal operation state. Since P2+P > P1, the charge power allocated to charge the energy storage battery module 104 can be P1-P. Furthermore, the energy storage battery module 104 can be continuously charged in a charging period (a period of time with solar illumination) without being damaged, so as to obtain high energy storage.
Third kind: if the output power satisfies p1> p2+p, it is determined that the value of the charging power for charging the energy storage battery module 104 is P2, and the value of the power supplied by the load power supply module 105 is P, where P1 is the output power, P is the rated power of the load power supply module 105, and P2 is the maximum allowable charging power of the energy storage battery module 104.
It can be appreciated that, in the case where the output power satisfies p1> p2+p, the value of the power supplied by the load power supply module 105 may be determined as the rated power P, so that the load 106 is in the optimal operating state. In addition, the charge power allocated to charge the energy storage battery module 104 is the maximum allowable charge power P2 of the energy storage battery module 104, so that the energy storage battery module 104 can be continuously charged in one charging period (a period with solar illumination) without being damaged, so as to obtain higher energy storage.
S24: the solar power generation module 101 is controlled to charge the energy storage battery module 104 with the value of the charging power, and the load power supply module 105 supplies power to the load 106 with the value of the power supply power.
The electric energy distribution method provided by the application can obtain the power output by the solar power generation module 101 and the state of charge value of the energy storage battery module 104; in the case where the state of charge value belongs to the first state of charge interval and the output power is greater than the minimum required power of the load power supply module 105, it is explained that the power output by the solar power generation module 101 can supply the power that can be operated to the load 106 while supplying the power to the energy storage battery module 104. In this way, the value of the power supply output by the load power supply module 105 and the value of the charging power for charging the energy storage battery module 104 are determined according to the output power and the rated power of the load power supply module 105. Finally, the solar power generation module 101 is controlled to charge the energy storage battery module 104 with the value of the charging power, and the load power supply module 105 supplies the load 106 with the value of the power supply power. In this way, the energy storage battery module 104 can continue to draw power during a charging cycle (period of time with solar illumination) while the load 106 is also operational as a result of being powered. It can be seen that, when the output power of the solar power generation module 101 is greater than the minimum required power of the load power supply module 105, the load power supply module 105 outputs a higher power supply power to the load 106 while the energy storage battery module 104 has a higher energy storage, so that the load 106 can operate due to being powered.
In addition, in one possible embodiment, the master control apparatus 100 determines a value of the charging power charged to the energy storage battery module 104 as a minimum value of the output power and the maximum allowable charging power of the energy storage battery module 104.
In the case where the output power is less than or equal to the minimum required power of the load power supply module 105, the load power supply module 105 cannot operate the load 106 even if the output power is distributed to the load power supply module 105 in its entirety. Therefore, only the value of the charging power charged to the energy storage battery module 104 is determined as the minimum value of the output power and the maximum allowable charging power of the energy storage battery module 104, so that the energy storage battery module 104 can be continuously charged in one charging period (a period with sunlight) without being damaged, so as to obtain higher energy storage, and the magnitude of the power supply power distributed to the load power supply module 105 is 0, so that the waste of electric energy is avoided.
In addition, in a possible implementation manner, the electric energy distribution method provided by the embodiment of the application may further include:
if the state of charge value belongs to the third state of charge interval and the output power satisfies p1+p3> P, determining that the value of the power supply power output by the load power supply module 105 is P and the value of the discharge power charged by the energy storage battery module 104 is P3, where the lower limit value of the third state of charge interval is greater than the upper limit value of the first state of charge interval.
It can be appreciated that in the case where the state of charge value falls within the third state of charge interval (e.g., [90%,100% ]), the service life of the energy storage battery module 104 is affected, and therefore, the energy storage battery module 104 can be discharged with a discharge power of P3. In the case where the output power satisfies p1+p3> P, the power supply power of the rated power P is allocated to the load power supply module 105, so that damage to the load 106 is avoided.
In addition, in one possible implementation manner, the electric energy distribution method provided by the embodiment of the application may further include:
if the state of charge value belongs to the third state of charge interval and the output power satisfies p1+p3< P, the value of the power supply power output by the load power supply module 105 is determined to be p1+p3, and the value of the discharge power discharged by the energy storage battery module 104 is determined to be P3. Where P1 is the output power, P is the rated power of the load power supply module 105, P3 is a constant greater than 0 (e.g., P3 may be 2kw, 3kw, or 4 kw), and the lower limit value of the third state of charge interval is greater than the upper limit value of the first state of charge interval. The solar power generation module 101 is controlled to discharge the energy storage battery module 104 with the discharge power of the value P3, and the load power supply module 105 is controlled to supply the load 106 with the power of the value p1+p3.
It can be appreciated that in the case where the state of charge value belongs to the third state of charge interval (e.g., [90%,100% ]), the service life of the energy storage battery module 104 is affected, and thus, the energy storage battery module 104 can be discharged with the discharge power of P3. If the output power satisfies p1+p3< P, the power supply power p1+p3 is distributed to the load power supply module 105, and the load 106 is not damaged.
In addition, in one possible implementation manner, if the state of charge value belongs to the second state of charge interval, determining that the value of the charging power for charging the energy storage battery module 104 is the minimum value of the output power and the maximum allowable charging power of the energy storage battery module 104, and the value of the power supply power output by the load power supply module 105 is 0, where the upper limit value of the second state of charge interval is lower than the lower limit value of the first state of charge interval; the solar power generation module 101 is controlled to charge the energy storage battery module 104 at the minimum value of the output power and the maximum allowable charge power of the energy storage battery module 104.
It will be appreciated that in the event that the state of charge value falls within the second state of charge interval (e.g., [0%,10% ]), it is indicated that the current energy storage battery module 104 stores little electrical energy, which is insufficient to provide sufficient electrical energy to the load 106 in the absence of illumination (e.g., at night). Therefore, the minimum value of the output power and the maximum allowable charge power of the energy storage battery module 104, and the value of the supply power output by the load power supply module 105 are determined to be 0. In this way, the energy storage battery module 104 can be enabled to distribute the charging power to the energy storage battery module 104 preferentially without being damaged
In addition, in the embodiment of the present application, in the case where the first switch module 102 is opened and the second switch module 103 is closed, the solar power generation module 101 may only distribute the power supply power to the load power supply module 105; the solar power generation module 101 may distribute the charging power only to the energy storage battery module 104 with the first switch module 102 closed and the second switch module 103 open.
Referring to fig. 3, an embodiment of the present application further provides an electric energy distribution device 300, which is applied to the master control apparatus 100. It should be noted that, the basic principle and the technical effects of the power distribution apparatus 300 provided in the embodiment of the present application are the same as those of the above embodiment, and for brevity, reference may be made to the corresponding contents of the above embodiment for the description of the embodiment of the present application. The main control device 100 is respectively in communication connection with the solar power generation module 101, the energy storage battery module 104 and the load power supply module 105, and the solar power generation module 101 and the energy storage battery module 104 are respectively and electrically connected with the load power supply module 105. The apparatus 300 comprises an information acquisition unit 301, an information determination unit 302 and an electrical energy distribution unit 303. Wherein,
the information acquisition unit 301 is configured to acquire power output by the solar power generation module 101 and a state of charge value of the energy storage battery module 104.
