Referring to fig. 1, fig. 1 is a block diagram of a charging application system according to an embodiment of the present application. As shown in fig. 1, the charging application 100 includes a server 110 and a charging pile 120, and the server 110 is communicatively connected to the charging pile 120. After obtaining the target charging request sent by the rest of terminal devices of the server 110, the server 110 confirms whether to execute the charging pile power adjustment operation according to the charging request power of the target charging request and the available power value of the charging pile 120 in the charging application system 100, so as to adjust the working power of the charging pile 120 in the working state to provide enough charging power for the load device specified by the target charging request, i.e. to meet the charging request power. In short, the server 110 is used for scheduling and adjusting the working power of the charging pile 120 in the charging application 100, so that more charging requests can be received by the charging application 100, and the total output power of the charging application 100 is not too high. One server 110 may be used to simultaneously correspond to a plurality of charging posts 120, or the charging application 100 includes a plurality of servers 110, where each server 110 corresponds to one or more charging posts 120. In an actual application scenario, one charging application 100 generally corresponds to an area power grid, and one charging application 100 includes a plurality of charging piles 120.

Based on this, the embodiment of the application provides a power scheduling method based on a regional power grid, and the embodiment of the application is described in detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a power scheduling method based on an area power grid according to an embodiment of the present application, where the method is applied to a server 110 in a charging application system 100 shown in fig. 1, and the charging application system 100 includes the server 110 and a plurality of charging piles 120; the method comprises the following steps:

step 201, when a target charging request from a terminal device is detected, acquiring a current power utilization state of a local power supply grid corresponding to a charging application system.

The terminal equipment is in communication connection with the server, the target charging request is used for indicating charging operation for target load equipment, the current power utilization state comprises an overrun power utilization state, an early warning power utilization state and a normal power utilization state, the overrun power utilization state is used for representing that the total output power of the power supply grid of the local area at the current moment is larger than or equal to a preset upper limit threshold, the upper limit threshold is the maximum safe power supply corresponding to the charging application system, the early warning power utilization state is used for representing that the total output power of the power supply grid of the local area at the current moment is larger than or equal to a preset early warning threshold, the early warning threshold is the minimum power utilization state which is determined according to experience and is obtained when the total output power of the power supply grid of the local area reaches the upper limit threshold under the load fluctuation state, the upper limit threshold is larger than the early warning threshold, and the normal power utilization state is used for representing that the total output power of the power supply grid of the local area at the current moment is smaller than the early warning threshold.

The specific application scenario related to the application is that the electric automobile uses the charging pile of the charging application system, or the electric automobile uses the charging pile of the charging application system, which is not limited in this time, and the method and the product related to the application can be applied to the situation that the charging pile is used by the load equipment which needs to use the charging pile for power supply or power distribution. Thus, specific devices included in the charging application system may have charging piles (equivalent to a power exchange station, a charging station, and the same will be understood in the methods related to the present application), power supply lines, power distribution transformers, network communication protocols, and the like, applied to the regional power grid. The server is a background server and is used for controlling the output power of the charging piles included in the charging application system, actively carrying out power regulation, orderly charging and closed-loop control for preventing the power consumption exceeding the limit, and can provide the service capability of the charging application system, prevent the power supply and distribution facilities from being damaged and avoid triggering the penalty of the power consumption exceeding the limit. The regional power supply grids are defined as minimum power supply service units which are divided by a power supply company according to a certain standard by the power supply region which is managed by the power supply company, and the upper limit threshold value and the early warning threshold value which correspond to each regional power supply grid are different.

The terminal device may be a mobile phone, or other electronic devices that may send a charging request to the server. The user sends a target charging request to the server by using the terminal device to request the load device of the user to perform charging operation, and in this case, in order to avoid that the total output power of the local power supply grid corresponding to the charging application system is greater than the maximum safe power supply power which can be born by the system or that the situation that the power consumption exceeds the ultra-limit power consumption may occur in the load fluctuation state, the server needs to acquire the current power consumption state of the charging application system at first, and then confirms how to perform the next operation.

Referring to fig. 3, fig. 3 is a schematic view of a scenario in which a user uses a charging pile according to an embodiment of the present application. As shown in fig. 3, 301 in the drawing is a charging pile in a charging application system, and may be any charging pile that is not used in the charging application system, i.e. is not in a working state; 302 in the figure is an electric automobile of a user, that is, a load device that needs a charging pile to perform a charging operation; in the figure, 303 is a user, that is, a user corresponding to a terminal device that initiates a charging request, and the user sends the charging request to 304 (that is, a server in a charging application system) in the figure through the terminal device to charge the electric automobile. And then, the server selects whether to charge the charging automobile or not according to the received charging request and the actual situation of the regional power grid. The method that the user sends the charging request to the server through the terminal device may be to start the charging request by scanning the two-dimensional code on the charging pile, or select the charging pile by using a specific application program and inform the server of the charging request, which is not limited in this time.

In one possible example, the obtaining the current power utilization state of the local power supply grid corresponding to the charging application system includes: acquiring a plurality of output powers of the plurality of charging piles at the current moment; summarizing the plurality of output powers to obtain the current total output power of the charging application system; judging whether the current total output power is greater than or equal to the upper threshold value: if the current total output power is judged to be greater than or equal to the upper limit threshold value, confirming that the current power utilization state of the charging application system is the overrun power utilization state; if the current total output power is judged to be smaller than the upper limit threshold value, judging whether the current total output power is larger than or equal to the early warning threshold value or not: if yes, confirming that the current power utilization state of the charging application system is the early warning power utilization state; and if not, confirming that the current power utilization state of the charging application system is the normal power utilization state.

Wherein the plurality of output powers and the plurality of charging piles are in one-to-one correspondence.

The method comprises the steps of obtaining current total output power by obtaining output power of all charging piles in a charging application system at the current moment, and comparing an upper limit threshold value with an early warning threshold value to obtain whether the power utilization state of the regional power supply grid at the current moment is in an overrun power utilization state, an early warning power utilization state or a normal power utilization state. The charging pile may be in an operating state or in a non-operating state.

In this example, the current total output power of the charging application system is obtained by obtaining the output powers of the charging piles at the current moment, so that the current power utilization state is confirmed by comparing the current total output power with the specific upper limit threshold value and the early warning threshold value corresponding to the power supply grid of the area, the next operation is confirmed according to the actual power utilization state, and the power supply stability of the charging application system and the flexibility of regulating and controlling the output power of the charging piles by the server are improved.

Step 202, obtaining preset requirements and available power values of the bearer service.

The receiving service requirement is used for representing whether the charging application system is allowed to receive a new charging request in the overrun power utilization state or the early warning power utilization state.

Because the charging application system is in an overrun state or an early warning state may cause an upstream trip accident due to exceeding the supply capacity of the upstream power office, for safety reasons, it is generally not allowed to accept new charging requests when the charging application system is in both states. Since the charging power is adjusted later in the application so that the total output power cannot be too high or fluctuate, the service receiving requirement can be set according to the actual situation, that is to say, the service receiving requirement can also be a new charging request receiving by the charging application system in an overrun power utilization state or an early warning power utilization state.

In one possible example, after the obtaining the preset carried service requirement and the available power value, the method further includes: if the current power utilization state is judged to be the over-limit power utilization state or the early warning power utilization state, and the receiving service requirement is characterized as not allowed, acquiring charging request power corresponding to the target charging request and a plurality of charging service information corresponding to a plurality of charging piles in a charging state at the current moment; obtaining required power according to the charging request power and the available power value; obtaining predicted waiting time according to the required power, the multiple charging service information calculation and the preset using interval duration; judging whether the estimated waiting time is longer than a preset time or not: if yes, confirming cancellation of the target charging request; if not, generating a waiting notification message according to the expected waiting time; and sending the waiting notification message to the terminal equipment.

The charging service information comprises charging remaining time and charging working power, and the charging piles in a charging state at the current moment are in one-to-one correspondence with the charging service information.

If the current power utilization state is judged to be the overrun power utilization state or the early warning power utilization state, and the receiving service requirement is characterized as not allowed, namely the charging application system is not allowed to receive a new charging request at the current moment. At this time, the target charging request is not directly canceled, but further processing analysis is performed by acquiring the charging request power corresponding to the target charging request and the charging service information of the charging pile in the charging state. The charging service information of the charging pile in the charging state is obtained because the charging pile which is not in the working state defaults to no output power for adjustment, and when the charging pile in the charging state completes charging for the corresponding load equipment, the charging power occupied by the charging service of the charging pile is released for other charging piles or the charging service of the new charging request. Therefore, the logic of this example is to calculate the required power required for reaching the charging request power, and then combine the service information of the charging pile currently in the charging state to determine the time for reaching the charging request power by the available power value in the charging application system, and inform the user. The judgment operation of adding the predicted waiting time and the preset time is to prevent the user from waiting excessively, the service experience is poor, the situation that the waiting time is long is eliminated for the user by comparing the predicted waiting time and the preset time in advance, and the cancellation of the target charging request is directly confirmed for the user.

Referring to fig. 4, fig. 4 is a schematic diagram of a waiting notification message according to an embodiment of the present application. As shown in fig. 4, at 9 days of 2/15 of 2023, the user receives a waiting notification message from the server, that is, 401 in the figure, the text content informs that the user can not provide charging service for the user temporarily, and the user needs to wait 30 minutes to charge the battery through calculation. In addition, two selection controls are provided to the user, namely a wait for control 402 in the figure and a cancel control 403 in the figure, to allow the user to select whether to continue queuing or cancel the charge request.

In this example, when the current power utilization state is an overrun power utilization state or an early warning power utilization state and the receiving service requirement is characterized as a disallowed branch, the waiting time for the user to reach the estimated waiting time is calculated through the actual current available power, the charging request power corresponding to the target charging request and the charging service condition of the charging pile in the actual charging state, so that the service capability of the charging station and the comprehensiveness of information data processing are improved.

In one possible example, the obtaining the estimated waiting time according to the required power, the calculation of the plurality of charging service information, and the preset usage interval duration includes: obtaining a plurality of charging remaining time lengths and a plurality of charging working powers according to the plurality of charging service information; according to the plurality of charging residual time lengths, sequencing the corresponding plurality of charging working powers from small to large to obtain a charging service completion sequence; sequentially superposing the charging working powers according to the charging service completion sequence until the sum of at least one of the superposed charging working powers is greater than or equal to the required power; determining the charge remaining time length corresponding to the last overlapped charge working power as a target charge remaining time length; and obtaining the predicted waiting time according to the target charging remaining time and the using interval time.

Each charging pile in a charging state corresponds to charging service information, and the charging service information comprises a corresponding charging residual duration and a corresponding charging working power. The shorter the remaining charging time length is, the earlier the charging service is ended, and the earlier the corresponding charging working power is released for a new charging request. Therefore, the charging service completion sequence can be obtained by sequencing from small to large, and the same can be understood as the discharging sequence of the charging working power. And then, by superposing the released charging working power until the required power is reached, determining which charging pile is used for completing the charging service, and taking the charging residual duration corresponding to the charging pile as the target charging residual duration when enough available charging power exists in the charging application system to meet the target charging request. The use interval duration is a reserved time provided for preventing a previous user from leaving the charging pile after the completion of charging, and the final expected waiting time can be obtained by adding the target charging remaining duration and the use interval duration.

Illustratively, there are now three charging posts in a charged state, namely charging post a, charging post B and charging post C. The remaining charge time and the charge operating power corresponding to them were "30 minutes", "3000 watts", "70 minutes", "6000 watts" and "50 minutes", "2000 watts", respectively. Thus, the charging service completion order is "3000 watts, 2000 watts, 6000 watts", and the required power is 4000 watts. Therefore, the charging working powers of the charging pile C and the charging pile a are overlapped according to the charging service completion sequence, so that the released power can meet the required power of the target charging request after the charging pile C finishes the charging service, the remaining charging time is 50 minutes, and the preset using interval time is 10 minutes, so that the expected waiting time is 60 minutes.

In this example, the target charging remaining duration can be calculated according to the charging service information and the required power, so as to obtain the predicted waiting duration, and improve the service capability of the charging station, and the stability and efficiency of information data processing of the server.

And 203, if the current power utilization state is judged to be the overrun power utilization state or the early warning power utilization state, and the receiving service requirement is characterized as permission, or the current power utilization state is judged to be the normal power utilization state, acquiring the charging request power corresponding to the target charging request.

And 204, if the available power value is less than the charging request power, executing the power adjustment operation of the charging pile to update the available power value.

The charging pile power adjusting operation is an operation power adjusting operation of an adjustable charging pile in a charging state at the current moment, wherein the adjustable charging pile is a charging pile which is pre-configured with low-load power, the current operation power is higher than the low-load power, and the low-load power is used for representing the operation power of the corresponding charging pile in the low-load operation state.

The charging pile power adjustment operation aims at a charging pile in a charging state, because only the charging pile in the charging state occupies larger output power, and the operation space and possibility of power can be reduced. Secondly, the charging pile is also an adjustable charging pile, wherein the adjustable charging pile is configured with corresponding low-load power in advance by staff, and the current working power is higher than the low-load power, that is, the charging pile is a space for adjusting the power, and a part of occupied working power can be released. Similarly, the non-adjustable charging pile includes two types, one is a charging pile whose current working power is at low load power, i.e., a charging pile that has been subjected to the overcharge pile power adjustment operation, and the other is a charging pile that has not been configured with low load power, i.e., a charging pile that has not been subjected to the charge pile power adjustment operation.

In one possible example, the performing a charging pile power adjustment operation to update the available power value includes: acquiring an adjusting charging pile sequence selection strategy and a plurality of reference charging piles corresponding to the charging application system; determining a target charging pile according to the charging pile sequence adjustment selection strategy and the reference charging piles; performing a charging power adjustment operation for the target charging stake; determining a power adjustment difference value according to the charging power adjustment operation; and updating the available power value according to the power adjustment difference value.

The charging power adjusting operation refers to adjusting the charging power of the target charging pile from the current working power to the low-load power corresponding to the target charging pile.

Wherein, in order to guarantee the stability and the processing efficiency of the previous charging business, only one charging pile is adjusted at a time by a single charging pile power adjustment operation. The mode of selecting the target charging pile is to select the charging pile which is most suitable for adjustment from the adjustable charging piles in the charging state according to a preset order selection strategy of the charging piles. The essence of the charging power adjustment operation is to increase the available power value in the charging application by adjusting the operating power of the charging stake from high power to low power, the increased available power value being the power adjustment difference value that the target charging stake performs to adjust for the charging power adjustment operation.

It can be seen that in this example, the target charging pile is determined by acquiring the charging pile order adjustment selection policy and the plurality of reference charging piles, then the charging power adjustment operation is performed for the target charging pile, and finally the available power value is updated according to the power adjustment difference. Therefore, the efficiency of regulating and controlling the power of the charging pile by the server and the stability of executing the charging service by the charging pile in the charging application system can be improved.

In one possible example, after the performing the charging pile power adjustment operation to update the available power value, the method further comprises: marking the charging pile subjected to the power adjustment operation as an adjusted charging pile, and recording a corresponding power adjustment difference value and operation execution time; whenever the existence of the charging pile is detected to exit the charging state, the following operations are performed: acquiring a release power value of the charging pile which exits from the charging state; acquiring at least one power adjustment difference value and at least one operation execution time corresponding to at least one adjusted charging pile in the charging state at the current moment; and adjusting the working power of the adjusted charging pile according to the at least one power adjustment difference value, the at least one operation execution time and the release power value.

The adjusted charging pile corresponds to a power adjustment difference value and an operation execution time, wherein the power adjustment difference value refers to an output power value reduced after the charging pile performs a power adjustment operation, and the operation execution time refers to the time after the charging pile performs the power adjustment operation. The release power value is the release power value because the corresponding charging service is not accepted after the charging pile completes the charging service, the working power required by the charging service is released when the charging service is executed. After the value is obtained, the released power is reused for recalling the charging pile which is adjusted previously and still in a charging state, so that the charging time is not excessively delayed due to the previous adjustment, the waiting time of a user is excessively prolonged, and the experience of the user is affected.

In this example, the charging pile that has performed the power adjustment operation of the charging pile is marked as the adjusted charging pile, and the corresponding power adjustment difference value and the operation execution time are recorded, so that after the charging pile completes the charging service, the adjusted charging pile can call back to the previous working power to meet the charging requirement of the server, and the flexibility of the server in executing the adjustment of the charging power is improved.

In one possible example, the performing a power callback operation to resume operating power of the adjusted charging pile based on the at least one power adjustment difference value, the at least one operation execution time, and the release power value comprises: obtaining a charging pile adjusting sequence according to the at least one operation execution time; and adjusting the working power of the corresponding adjusted charging pile back to the initial working power in sequence according to the charging pile adjusting sequence, the at least one power adjusting difference value and the release power value.

The charging pile adjusting sequence is used for indicating the sequence of the charging piles for executing the power adjustment of the charging piles, the charging pile adjusting sequence corresponds to at least one adjusted charging pile, the at least one adjusted charging pile corresponds to the at least one power adjustment difference value one by one, and the initial working power refers to the working power of the corresponding adjusted charging pile before executing the power adjustment operation of the charging piles.

In one possible example, the adjusted charging pile order selection strategy is any one of the following: the reference charging pile with the earliest corresponding charging service starting time is preferentially adjusted, the reference charging pile with the latest corresponding charging service starting time is preferentially adjusted, and the reference charging pile with the largest corresponding charging service using power is preferentially adjusted.

The reference charging pile with the earliest starting time of the corresponding charging service is preferably adjusted, and the charging pile which is most convenient to complete the charging service in the reference charging pile is preferably adjusted, and the power of the charging pile is preferably adjusted, so that the influence on the completion of the whole charging pile service is less; the reference charging pile with the latest starting time of the corresponding charging service is preferentially adjusted, so that the charging pile which just starts the charging service in the reference charging pile can be understood as the charging pile which just starts the charging service is preferentially adjusted, because the user corresponding to the charging service just begins to wait for charging, the power of the charging pile is firstly adjusted down to properly prolong the waiting time, and the user is not greatly different; and finally, preferentially adjusting the reference charging pile with the maximum power used by the corresponding charging service, wherein the charging pile occupies the maximum power in all the reference charging piles, and the full-rate available power value can be released to meet the new charging request by adjusting the use power of the charging pile.

Therefore, in the example, by setting various charging pile order selection strategies to ensure that the determined target charging pile has the smallest influence on the charging service after power adjustment, the efficiency and stability of the server for power adjustment of the charging pile are improved.

Step 205, after the power adjustment operation of the charging pile is completed, it is determined whether the updated available power value is greater than or equal to the charging request power.

Step 206, executing charging operation for the target load device according to the target charging request, and updating the available power value according to the charging request power; and confirming completion of the target charge request.

Step 206 is a specific step after determining that the updated available power value is greater than or equal to the charging request power, which is the yes branch after the execution of the determining step 205. When the server judges that the updated available power value is greater than or equal to the charging request power, that is, the current charging application system is the charging service capable of processing and completing the target charging request, the subsequent step is to execute the charging operation for the target load device according to the target charging request, update the available power value again, and finally confirm that the target charging request is completed.

And the updated available power value in the updated available power values is the remaining power value obtained by subtracting the charging request power from the updated available power value.

Step 207, repeatedly executing the power adjustment operation of the charging pile until the updated available power value is greater than or equal to the charging request power, or confirming that no adjustable charging pile exists; and if the adjustable charging pile is confirmed to be absent, confirming to cancel the target charging request; or if the updated available power value is greater than or equal to the charging request power, executing charging operation for the target load equipment according to the target charging request, and updating the available power value according to the charging request power; and confirming completion of the target charge request.

Step 207 is a specific step after determining that the updated available power value is greater than the charging request power, if the step 205 is not performed. When the server judges that the updated available power value is smaller than the charging request power, the current charging application system cannot accept and complete the charging service of the target charging request, and the charging pile power adjustment operation needs to be executed again to adjust other adjustable charging piles so that the final updated available power value can meet the charging request power. Of course, it may happen that all charging piles in a charging state cannot be adjusted, and then the charging application system cannot charge the target load device under the current situation, and the cancellation of the target charging request is confirmed. If the user wants to charge the load equipment, the user can only wait for the charging of the equipment before charging to be completed, and can successfully charge the load equipment when the sufficient available power value exists in the charging application system.

In one possible example, after the confirmation of completion of the target charge request, the method further includes: starting a patrol scanning timer; when no new charging request is detected within the timing range of the patrol scanning timer, the following patrol scanning operation is executed: acquiring a plurality of output powers of the plurality of charging piles in the charging application system at the current moment; summarizing the plurality of output powers to obtain the current total output power of the charging application system; comparing the current total output power with the upper threshold: if the current total output power is greater than or equal to the upper limit threshold value, confirming that the current power utilization state of the charging application system is the overrun power utilization state; and performing the charging pile power adjustment operation; and re-executing the patrol scanning operation after the power adjustment operation of the charging pile is completed; if the current total output power is smaller than the upper limit threshold, judging whether the current total output power is larger than or equal to the early warning threshold or not: if yes, confirming that the current power utilization state of the charging application system is the early warning power utilization state; if not, confirming that the current power utilization state of the charging application system is the normal power utilization state; and confirming that the inspection scanning is completed, and restarting the inspection scanning timer.

The reason why the inspection scanning operation needs to be re-performed after the power adjustment operation of the charging pile is performed is that a single power adjustment operation of the charging pile may not be sufficient to enable the charging application system to recover from the over-power-consumption state to the early-warning power-consumption state or the normal power-consumption state, and thus the scanning operation needs to be performed again. The time of the timer can be adjusted according to the number of the charging piles and the actual use frequency of the charging piles, and the time is not limited herein. The shorter the time length of the timer is, the more frequent the scanning is, the more rapid the condition of over-limit electricity utilization can be detected and adjusted, but the larger the corresponding electricity consumption is, the corresponding setting should be carried out according to the condition of each regional power supply grid.

Disclosed in this example is an algorithm flow for timing scan of grid power usage and execution of power scheduling. The function of the algorithm flow is that the server dynamically adjusts the output power of the charging pile in the charging application system, uniformly schedules the power utilization facilities of the charging stations/power exchange stations in the regional power supply grid, achieves the organic balance of power utilization requirements and power supply and distribution capacity, prevents the charging application system from exceeding the limit of power utilization, and further avoids triggering the penalty of exceeding the limit of power utilization.

It can be seen that in this example, by increasing the patrol scan timer to make a detection amount adjustment of the current total output power of the charging application system, the charging application system is prevented from being in an over-limit power state, thereby causing a problem of equipment damage or upstream trip. The stability and the safety of the charging service of the charging application system are improved.

Fig. 2 is a schematic flow chart of a power scheduling method based on a regional power grid according to an embodiment of the present application. As shown in fig. 2, when a new charging request is detected, the current power utilization state, the preset receiving service requirement and the available power value of the charging application system are obtained, and if it is determined that the new charging request can be received, the charging request power of the new charging request is obtained. If the available power value is smaller than the charging request power, executing the charging pile power adjustment operation to update the available power value, and after the charging pile power adjustment operation is completed, judging whether the updated available power value is larger than or equal to the charging request power: if yes, executing the charging operation of the target liability equipment corresponding to the new charging request to complete the charging request; if not, repeating the power adjustment operation of the charging pile, and confirming cancellation or finishing the charging request according to the execution result. Therefore, the service capacity of the regional power supply grid and the flexibility of the power scheduling of the charging pile by the server are improved by executing the power adjustment operation of the charging pile, and the problem of equipment damage caused by the power utilization exceeding the limit of the charging application system can be effectively avoided.
