DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

As shown in fig. 1, in one embodiment, the present invention provides a power scheduling method applied to an energy router 600 as shown in fig. 6. The energy router 600 is configured to be disposed in a power consumption area, and is connected to the power supply device 20 and the charging device 30, respectively.

The power supply device 20 is configured to be connected to the external power supply device 10, receive the electric energy input by the external power supply device 10, and use the electric energy input by the power supply device 10 as the total input power of the power consumption region; the power supply device 20 is further configured to be connected to the energy router 600 and the consumer object, respectively, and provide electric energy to the energy router 600 and the consumer object, respectively.

The charging device 30 is configured to be connected to the energy router 600 and the powered device, respectively, receive power input by the energy router 600, and charge the powered device connected thereto with the power.

The power utilization area is any area range using electric energy, can be determined according to an actual power utilization scene, and comprises but is not limited to an industrial power utilization area and a domestic power utilization area; the electricity utilization entity object is an entity object consuming electric energy, and can also be determined according to an actual electricity utilization scene, and the electricity utilization entity object includes but is not limited to one of industrial equipment and domestic electricity utilization equipment in an electricity utilization area.

For example, in some embodiments, the electricity consumption region is a residential cell, the users in the electricity consumption region are residents, the power supply device 20 is a transformer disposed in the electricity consumption region, the electricity consumption physical objects include at least a domestic electricity consumption device 40 and a charging device 30 in the residential cell, the charging device 30 includes but is not limited to a charging pile, and the power receiving device includes but is not limited to one of an electric vehicle, an electric bicycle, and a storage battery; specifically, the transformer is configured to receive total input power input by the external power supply device 10 and distribute the total input power, and specifically, the transformer inputs a part of the total input power as user power to the consumer electrical devices 40, and also uses a part of the total input power as available power, and distributes power to the charging device 30 by using the available power through the energy router 600, and the charging device 30 may charge the electric vehicle according to the power. The available power includes two parts, one part is allocated power allocated to the charging device 30, and the other part is remaining power to be power allocated, that is, the remaining power is a power value that can be power allocated by the energy router 600.

It should be noted that the specific structural form and number of the charging devices 30 may be set according to the actual use requirement, and in some embodiments, the charging device 30 includes a first device 31 to release power and a second device 32 to distribute power.

Here, it should be noted that, the energy router 600 has allocated power to the first device 31, that is, the first device 31 receives the allocated power, the power of the first device 31 is not 0, and when the remaining power of the energy router 600 is not enough to be allocated to the second device 32, the energy router 600 may perform power release processing on the first device 31, that is, the energy router 600 stops continuing to allocate power to the first device 31, and recovers the allocated power originally allocated to the first device 31, so as to increase the remaining power; energy router 600 does not allocate power to second device 32, the power of second device 32 is 0, and second device 32 waits for energy router 600 to allocate power to it using the remaining power, or, in another case, energy router 600 has allocated power to second device 32, that is, second device 32 receives the allocated power, the power of second device 32 is not 0, but the allocated power (i.e., the current actual power) of second device 32 is still lower than the required power, so that the charging efficiency of second device 32 is limited, and in order to improve the charging efficiency of second device 32, second device 32 waits for energy router 600 to allocate charging compensation power to it using the remaining power.

The power scheduling method comprises the following steps:

step 102, when a preset first characteristic condition is met, performing power release processing on at least one first device 31.

The step 102 is a power release processing step, and the first characteristic condition is used to characterize that the energy router 600 generates a power release demand, which is used as a trigger condition of the power release processing, and the energy router 600 generates the power release demand when the current remaining power is insufficient to allocate power to the second device 32, so that the allocated power allocated to the first device 31 is recycled, thereby achieving the effect of increasing the remaining power. It is worth mentioning that the first characteristic condition may be preset according to the requirement of actual use.

Specifically, when a preset first characteristic condition is satisfied, the energy router 600 generates a power release control instruction, and under the instruction of the power release control instruction, the energy router 600 performs power release processing on the at least one first device 31, that is, the energy router 600 stops allocating power to the at least one first device 31.

Step 104, obtain a first remaining power of energy router 600.

In step 104, the first remaining power is used to characterize the remaining power to be power allocated by the energy router 600 after performing the power release process.

Step 106, allocating power to the second device 32 by using the first remaining power according to the power information of the second device 32.

Wherein, in step 106, the power information of the second device 32 includes at least one of the actual power and the required power of the second device 32.

In the above power scheduling method, the step of performing power release processing on the first device 31 is performed, and then according to the power information of the second device 32, the power is allocated to the second device 32 by using the first remaining power obtained after the power release processing, so that the power recovered after the power release processing from the first device 31 is allocated to the second device, the phenomenon that the energy router 600 is idle in power is avoided, the utilization rate of the power is effectively improved, the charging device 30 can be charged by fully using the power, and the charging efficiency of the charging device 30 is improved.

As shown in fig. 2 and 6, in an embodiment, before the step of performing the power release process on the at least one first device 31 when the preset power release condition is met, the method includes:

step 202, obtain a second remaining power of energy router 600.

In step 202, the second remaining power is used to characterize the remaining power to be allocated by the energy router 600 before performing the power release process.

Step 204, obtaining the power to be distributed according to the power information of the second device 32.

Wherein, in step 204, the power to be allocated is used for characterizing the target power value of the power allocation of the second device 32, and in some embodiments, the power information of the second device 32 includes the actual power and the required power of the second device 32.

Specifically, the required power P of the second device 32 may be obtained first₀And the actual power P₁And obtaining the power to be distributed according to the power difference value delta P.

For example, in some embodiments, the power difference Δ P is taken as the power to be allocated, specifically:

(1) when the actual power P of the second device 32₁When 0, i.e. the second device 32 does not receive the allocated power, the power difference Δ P is equal to the required power P₀。

(2) When the actual power P of the second device 32₁When not equal to 0, i.e. the second device 32 has received the allocated power, it should be noted that the required power P of the second device 32₀And the actual power P₁When the charging conditions are equal, the second device 32 is in the ideal charging condition, and the second device 32 in the ideal charging condition charges the powered device most efficiently, but the power capable of being scheduled by the energy router 600 changes dynamically, so that the actual power P of the second device 32 often occurs during the power allocation process₁Less than the required power P₀The charging efficiency of the second device 32 is limited, and the required power P of the second device 32₀And the actual power P₁Difference in power Δ P (Δ P ═ P) between them₀-P₁) The smaller the power difference Δ P is, the higher the charging efficiency of the second device 32 is, and conversely, the lower the charging efficiency is, and here, the power difference Δ P is taken as the power to be allocated, which can be understood as that the power to be allocated is taken as the power compensation value of the second device 32, which provides a condition for the step of the subsequent energy router 600 respectively compensating the power to the second device 32 by using the first residual power or the second residual power according to the power to be allocated, provides a basis for dynamically compensating the actual power of the second device 32, and avoids the required power P by the subsequent dynamic power compensation₀And the actual power P₁The case of the power difference Δ P therebetween being too large is beneficial to ensuring the charging efficiency of the second device 32 as much as possible under the limited condition.

In addition, in other embodiments, after the power difference value Δ P is obtained, the power P to be distributed is obtained according to the product calculation of the power difference value Δ P and the proportionality coefficient k₂Δ P × k, wherein the scaling factor k may be preset according to actual use requirements.

In step 206, when the power to be allocated is greater than zero and the second remaining power is less than the power to be allocated, it is determined that the first characteristic condition is satisfied.

And step 208, when the second residual power is greater than or equal to the power to be distributed, distributing the power to the second device 32 by using the second residual power according to the power to be distributed.

In step 208, since the second remaining power is greater than or equal to the power to be allocated, it indicates that the second remaining power is sufficient to meet the requirement of the energy router 600 for allocating power to the second device 32, and at this time, the energy router 600 directly allocates power to the second device 32 using the second remaining power.

As shown in fig. 3 and 6, in an embodiment, before the step of performing the power release process on the at least one first device 31 when the preset power release condition is met, the method includes:

in step 302, any charging device 30 that satisfies the preset second characteristic condition is determined as the first device 31.

In step 302, the second characteristic condition is used to represent a condition that the charging device 30 has power release, and it is worth mentioning that the second characteristic condition may be preset according to a requirement of actual use, for example, the second characteristic condition is preset according to at least one of an access time, a charging priority, a charging duration, and a charging amount of the charging device 30.

Specifically, the manner of determining whether the charging device 30 satisfies the second characteristic condition includes at least one of:

first, it is determined whether the charging device 30 satisfies the second characteristic condition based on the charging operation information of the charging device 30. The charging operation information of the charging device 30 includes at least one of access time information, charging priority information, charging duration information, and electric quantity information of the charging device 30.

The first determination method includes, but is not limited to, at least one of the following cases:

(1) according to the access time information of the charging equipment 30, the charging equipment 30 which is accessed before the preset access time is judged to meet the second characteristic condition; the preset access time may be specifically set according to actual use requirements, for example, in some embodiments, if the preset access time is 2 hours, the charging device 30 accessed before 2 hours is determined to meet the second characteristic condition;

(2) according to the charging priority information of the charging equipment 30, the charging equipment 30 with the charging priority lower than or equal to the preset priority threshold is judged to meet the second characteristic condition; the preset priority threshold may be specifically set according to actual use requirements, for example, in some embodiments, the priority of the charging device 30 is set to 0, 1, 2, and 3, where 0 is the lowest priority and 3 is the highest priority, and the preset priority threshold is set to 1, and then the charging device 30 with a priority lower than or equal to 1 is determined to satisfy the second characteristic condition;

(3) according to the charging duration information of the charging equipment 30, the charging equipment 30 with the charging duration higher than or equal to the preset charging time threshold is judged to meet the second characteristic condition; the preset charging time threshold may be specifically set according to actual use requirements, for example, in some embodiments, if the preset charging time threshold is 2 hours, the charging device 30 with a charging time length higher than or equal to 2 hours is determined to meet the second characteristic condition;

(4) according to the electric quantity information of the charging equipment 30, the charging equipment 30 with the electric quantity higher than or equal to the preset electric quantity threshold is judged to meet the second characteristic condition; for example, in some embodiments, the preset electric quantity threshold is 90%, and then the charging device 30 with the electric quantity higher than or equal to 90% determines that the second characteristic condition is satisfied.

Of course, in other embodiments, it may also be determined whether the charging device 30 meets the second characteristic condition according to at least two of the access time information, the charging priority information, the charging duration information, and the electric quantity information of the charging device 30, for example, in one embodiment, according to the charging priority information and the electric quantity information of the charging device 30, the charging device 30 whose charging priority is lower than or equal to the preset priority threshold and whose electric quantity is higher than or equal to the preset electric quantity threshold is determined as meeting the second characteristic condition; of course, in other embodiments, whether the charging device 30 meets the second characteristic condition may also be determined jointly according to at least three or at least four of the access time information, the charging priority information, the charging duration information, and the electric quantity information of the charging device 30, where the determination principle is similar to the above determination principle, and is not repeated herein.

Secondly, the user manually sets any charging device 30 as a power releasing device by operation, and the power releasing device satisfies the second characteristic condition, that is, any charging device 30 satisfies the second characteristic condition by means of manual selection.

In step 304, when the first device 31 is present in the charging device 30, it is determined that the first characteristic condition is satisfied.

Through the setting of the step 302 and the step 304, the determination of the first device 31 is realized according to different types of charging operation information of the charging device 30, the determination of the first device 31 in different charging operation states is enriched, and because the charging operation information of the charging device 30 changes in real time along with the actual operation state of the charging device 30, the dynamic determination of the first device 31 is realized through the setting of the step, which is favorable for increasing the determination capability of the first device 31, so that the power scheduling method is suitable for more application scenarios, and a reliable condition is provided for the subsequent power release of the first device 31.

It should be noted that, in some embodiments, when it is determined that the first device 31 includes a plurality of devices, the foregoing step 102 may be executed multiple times, so as to implement the power release processing of the energy router 600 for each first device 31 one by one, and each time the step 102 is executed, the power of one first device 31 is released, and accordingly, a determination is made to determine whether the energy router 600 has a power release requirement, if the current first remaining power of the energy router 600 is smaller than the power to be allocated of the second device 32, that is, the current first remaining power of the energy router 600 is not enough to allocate power to the second device 32, it is determined that the energy router 600 has the power release requirement, the next step 102 is executed to release the power of the next first device 31, and a next determination is made to determine whether the energy router 600 has the power release requirement, and so on, until energy router 600 does not have a power release requirement, stop executing next step 102.

In some embodiments, in order to increase the efficiency of the power release process for the plurality of first devices 31, step 102 is performed once, and at this time, energy router 600 may release the power of the plurality of first devices 31 at the same time, i.e., stop the distribution of power to the plurality of first devices 31 at the same time.

When the energy router 600 simultaneously performs power distribution or power release on the plurality of charging devices 30, the plurality of charging devices 30 are orderly subjected to power scheduling (including power distribution and power release), so that faults of not-in-place power distribution, not thorough power release, not flexible power scheduling and the like caused by the fact that the energy router 600 performs disordered power scheduling are avoided, and the probability of faults of the energy router 600 is effectively reduced. The following description will be made for different power scheduling cases respectively:

in one embodiment, the step of performing the power release process on the at least one first device 31 comprises the steps of:

according to the charging operation information of the first devices 31, sequentially performing power release processing on the first devices 31; the charging operation information of the first device 31 includes at least one of access time information, charging priority information, charging duration information, and power information of the first device 31.

Through the setting of the above steps, the orderliness of the energy router 600 for performing the power release processing on the first device 31 is effectively increased, the failure rate of the power release control of the energy router 600 is reduced, and the use reliability of the energy router 600 is high.

Further, as shown in fig. 4 and 6, in an embodiment, the step of sequentially performing the power release process on the first devices 31 according to the charging operation information of the first devices 31 includes:

step 402, obtaining a power release queue according to the charging operation information of the first device 31.

In step 402, the power release queue is used to characterize the order of power release processing of each first device 31. Specifically, the power release processing sequence of each first device 31 is sorted according to at least one of the access time information, the charging priority information, the charging duration information, and the electric quantity information of the first device 31, so as to obtain the power release queue.

For example, in some embodiments, each first device 31 is sequentially added to the power release queue according to the charging priority information of each first device 31, specifically, first, the first device 31 with the lowest priority is accessed to the power release queue and located at the head of the power release queue, then, according to a rule that priorities are sequentially increased, the first devices 31 corresponding to each priority are sequentially accessed to the power release queue, and finally, the first device 31 with the highest priority is accessed to the power release queue and located at the tail of the power release queue.

In step 404, the power release processing is performed on the first devices 31 in sequence according to the power release queue.

In step 404, a query pointer for instructing any first device 31 to perform power release is preset, and the query pointer is used to point to the first devices 31 located in the power release queue in sequence, specifically, when the power release queue is not empty, the query pointer is used to point from the first device 31 currently located at the head of the power release queue, under the instruction of the query pointer, the first device 31 currently located at the head of the power release queue performs power release, after the first device 31 currently located at the head of the power release queue finishes power release, the query pointer moves down, that is, the query pointer points to the next first device 31 currently located after the head of the power release queue, then, the first device 31 pointed by the query pointer performs power release, and so on, until the current first remaining power of the energy router 600 is enough to allocate power to the second device 32, or, the query pointer stops moving downwards until the power release of all the first devices 31 in the power release queue is finished, so that the query pointer is used for sequentially controlling the first devices to be located in the power release queue.

Through the setting of the

steps

402 and 404, the orderliness of the energy router 600 in performing the power release processing on the first device 31 is further increased, and the failure rate of the power release control of the energy router 600 is better reduced, so that the use reliability of the energy router 600 is further improved.

In one embodiment, the step of allocating power to the second device 32 using the first remaining power according to the power information of the second device 32 comprises:

sequentially distributing power to the second devices 32 by using the first remaining power according to the charging operation information of the second devices 32 and the power information of the second devices 32; the charging operation information of the second device 32 includes at least one of access time information, charging priority information, charging duration information, and electric quantity information of the second device 32.

Through the arrangement of the above steps, the orderliness of the energy router 600 for performing power distribution on the second device 32 is effectively increased, the failure rate of power distribution control of the energy router 600 is reduced, and the use reliability of the energy router 600 is high.

Further, as shown in fig. 5 and 6, in an embodiment, the step of sequentially allocating power to the second devices 32 by using the first remaining power according to the charging operation information of the second devices 32 and the power information of the second devices 32 includes:

step 502, obtaining a power distribution queue according to the charging operation information of the second device 32.

Wherein, in step 502, the power distribution queue is used to characterize the order of the distributed power of the energy router 600 to the second devices 32. Specifically, the power allocation sequence of each second device 32 is sorted according to at least one of the access time information, the charging priority information, the charging duration information, and the electric quantity information of the second device 32, so as to obtain a power allocation queue.

For example, in some embodiments, the second devices 32 are sequentially added to the power distribution queue according to the charging priority information of the second devices 32, specifically, first, the second device 32 with the highest priority is accessed to the power distribution queue and located at the head of the power distribution queue, then, according to a rule that the priorities are sequentially decreased, the second devices 32 corresponding to the priorities are sequentially accessed to the power distribution queue, and finally, the second device 32 with the lowest priority is accessed to the power distribution queue and located at the tail of the power distribution queue.

Step 504, sequentially allocating power to the second device 32 using the first remaining power according to the power allocation queue and the power information of the second device 32.

In step 504, a query pointer for instructing any one of the second devices 32 to perform power allocation is preset, the query pointer is used to sequentially point to the second devices 32 located in the power allocation queue, specifically, when the power allocation queue is not empty, the query pointer is used to point from the second device 32 currently located at the head of the power allocation queue, under the instruction of the query pointer, the power allocation is performed on the second device 32 currently located at the head of the power allocation queue, after the power allocation on the second device 32 currently located at the head of the power allocation queue is completed, the query pointer is moved down, that is, the query pointer points to the next second device 32 currently located after the head of the power allocation queue, then, the power allocation is performed on the second device 32 pointed by the query pointer, and so on, until the power allocation control on all the second devices 32 in the power allocation queue is completed, the query pointer stops moving downwards, and sequential control of the query pointer in the power distribution queue is realized.

Through the setting of the step 502 and the step 504, the orderliness of the energy router 600 for performing power distribution on the second device 32 is further increased, and the failure rate of the power distribution control of the energy router 600 is better reduced, so that the use reliability of the energy router 600 is further improved.
