However, the large-scale charging demand of electric vehicles has put forward new requirements for the stability and reliability of the power grid. The charging demand of electric vehicles is random and volatile.

[0013] If the load factor of the distribution transformer is between the load factor over-limit decreasing threshold and the load factor over-limit recovering threshold, the transformer is in an intermediate load factor state, and no strategy is executed.

[0014] According to some embodiments, the charging data of the charging pile includes:

[0015] Charging status, minimum output power, real-time power, rated power, set power, remaining battery capacity and maximum battery capacity;

[0016] The charging data of the charging piles are the data of each charging pile.

[0017] According to some embodiments, the number of charging pile control gears is used to determine the power of each charging pile control;

[0018] The minimum control cycle of the charging pile is used to determine the interval time between two distribution transformer load rates within the charging pile area.

[0019] According to some embodiments, executing the power reduction strategy includes:

[0024] Execute power reduction for the specified charging pile according to the preset control step length;

[0025] If there is no charging pile that meets the power reduction conditions, the power reduction strategy is terminated and the minimum control cycle T waiting time is entered.

[0037] Processor; and

[0038] A memory stores a computer program, and when the computer program is executed by the processor, the processor executes any of the aforementioned methods.

[0039] According to an exemplary embodiment of the present invention, by acquiring the charging data of the charging pile and the transformer gateway data in real time through the intelligent fusion terminal of the substation, the timeliness and accuracy of the data can be ensured, and comprehensive data support can be provided. Subsequently, the charging power of the charging pile can be dynamically adjusted according to the real-time data to ensure the stable operation of the power grid. By reasonably setting the parameters of the charging pile and the overall parameters, the overload and frequent fluctuations of the power grid can be effectively avoided, and the stable operation of the system can be maintained. The setting of multi-gear adjustment and the minimum control cycle can optimize the utilization of power resources, improve the efficiency of the use of charging piles, and reduce energy waste. The setting of the load rate over-limit drop threshold and the recovery threshold can effectively prevent and respond to overload risks and ensure the safe operation of the power grid; by monitoring and judging the load rate of the distribution transformer, real-time monitoring and dynamic adjustment can effectively reduce the load fluctuation of the power grid and improve the overall stability of the system.

[0040] Through the method of the present invention, when the load rate of the distribution transformer exceeds the load rate over-limit reduction threshold, it indicates that the transformer is in a load rate over-limit state, and a power reduction strategy is executed to orderly reduce the output power of the charging pile to reduce the load rate of the transformer in the substation area, prevent transformer overload, and avoid power grid failure. When the load rate of the distribution transformer is lower than the load rate over-limit recovery threshold, a power recovery strategy is executed to orderly restore the output power of the charging pile. Executing the corresponding power strategy based on the results can significantly improve the safety and stability of the power grid, optimize the utilization of power resources, enhance user experience, and support system maintenance and fault diagnosis.

[0055] In view of the large-scale charging demand of electric vehicles for the stability of the power grid, a charging pile area orderly charging control method is proposed. It can detect the real-time load rate of the area in real time, coordinate all charging piles in the area, and reduce the area load at the minimum cost by adjusting the real-time output power, effectively solving the problem of overload in the area.

[0056] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings.

[0057] Figure 1 A flow chart of a method for orderly charging regulation of a charging station area according to an example embodiment is shown.

[0058] This method can effectively utilize the historical data of surrounding stations and provide reliable historical irradiance prediction for newly built photovoltaic power stations.

[0059] In S101, the charging data of the charging piles connected to the substation and the transformer gateway data are acquired in real time through the substation intelligent fusion terminal, wherein the transformer gateway data includes the distribution transformer load rate.

[0060] According to the exemplary embodiment, the charging state of the charging pile area is controlled by the area intelligent fusion terminal, and the charging data and transformer gateway data of the charging piles connected to the area are obtained in real time through the area intelligent fusion terminal. The transformer gateway data includes the distribution transformer load rate L rate The charging data of the charging pile is the data of each charging pile, and the charging data of the charging pile includes charging state, minimum output power, real-time power, rated power, set power, remaining battery capacity and maximum battery capacity; charging state St, minimum output power P min , real-time power P real , Rated power P n , set power P set 、Battery remaining capacity S rem With the maximum battery capacity S max , the set power P set Supports setting and reading by the intelligent fusion terminal of the substation area; the charging state St, if the charging pile is currently charging, St is 1; if it is not currently charging, St is 0. The transformer gateway data also includes the transformer capacity S n And the real-time power factor PF of the substation.

[0061] The intelligent fusion terminal of the substation area can effectively obtain the charging data of the charging pile and the gateway data of the transformer in real time, providing reliable data support for subsequent load evaluation, intelligent scheduling and dynamic adjustment.

[0062] In S103, charging pile parameters and overall parameters are obtained.

[0063] According to an exemplary embodiment, the charging pile parameters include the number of charging pile control gears n d , the minimum control cycle T of the charging pile, the overall parameters include the load rate over-limit drop threshold Sr down , Load rate over-limit recovery threshold Sr up .

[0064] The number of gears controlled by the charging pile n d , which is used to determine the power of each charging pile regulation, that is, the charging pile regulation step length P sgset , P sgset The calculation method is:

[0065]

[0066] The minimum control cycle T of the charging pile is the load rate L of the two distribution transformers in the substation area. rate The interval time of judgment is based on the load factor L of the distribution transformer after judgment. rate The execution strategy of the interval.

[0067] By setting reasonable charging pile parameters and overall parameters, the load of the charging pile area can be effectively managed to ensure the stability and reliability of the power grid. The reasonable configuration of the charging pile parameters and overall parameters is the key to achieving orderly charging regulation.

[0068] The number of charging pile control gears described in this embodiment can improve the flexibility of charging pile power regulation, and can adjust the charging power more finely according to actual needs. Through multi-gear regulation, it is possible to minimize unnecessary high-power charging while ensuring charging needs, thereby saving energy. Setting the minimum regulation cycle can avoid frequent power adjustments, reduce the impact on the power grid, and maintain the stability of the system. A reasonable load rate over-limit drop threshold can take timely measures when the transformer load rate approaches the critical value to prevent overload and ensure the safe operation of the power grid; a reasonable load rate over-limit recovery threshold setting can restore the charging power in time when the transformer load rate drops to a safe range, ensuring that the utilization rate of the charging pile and the charging needs of users are met.

[0069] In S105, the load factor of the distribution transformer is monitored and determined, and a corresponding power strategy is executed in real time according to the results of the monitoring and determination.

[0070] In the orderly charging control method of charging pile area, monitoring and judging the load rate of distribution transformer is a key step to ensure the stability of the power grid. According to the different states of the load rate of distribution transformer, the system will implement different power strategies. For the specific judgment process, see Figure 2 .

[0071] According to an exemplary embodiment, the load rate of the distribution transformer is monitored and determined. If the load rate of the distribution transformer L rateGreater than the load rate over-limit drop threshold Sr down , indicating that the transformer is in a load rate over-limit state, and the power reduction strategy is executed; if the distribution transformer load rate L rate Less than the load rate over-limit recovery threshold Sr up , the load rate over-limit recovery threshold Sr up Less than Sr down 10% indicates that the transformer is in a safe load rate state and a power recovery strategy needs to be implemented;

[0072] If the distribution transformer load factor L rate When the load rate exceeds the limit drop threshold Sr down and load rate over-limit recovery threshold Sr up During this period, the transformer is in an intermediate load rate state and does not execute any strategy, waiting for the minimum control cycle of the charging pile.

[0073] Through this example embodiment, the system can monitor the load rate of the distribution transformer in real time, and execute the corresponding power strategy in real time according to different load states to ensure the stability and reliability of the power grid. This method of orderly charging control in the charging pile area can not only effectively manage the load of the charging pile area, but also improve the utilization efficiency of power resources.

[0074] Figure 3 A flow chart for executing a power reduction strategy according to an example embodiment is shown.

[0075] The power reduction strategy is to reduce the output power of the connected charging pile to reduce the transformer load rate.

[0076] In S201, it is determined whether there is a charging pile that meets the power reduction condition.

[0077] According to an exemplary embodiment, all charging piles that meet the power reduction condition are screened, wherein the power reduction condition includes that the charging pile charging state St=1 and the current P of the charging pile set >P min If there is no charging pile that meets the reduction conditions, enter S217, the power reduction strategy is terminated, and return to the minimum control cycle T waiting time.

[0078] In S203, a priority standard value is calculated for the charging piles that meet the power reduction condition.

[0079] According to an exemplary embodiment, a priority standard value is calculated for a charging pile that meets the power reduction condition, and the priority standard value is used as a basis for regulating the charging pile. The priority standard value Y is calculated as follows:

[0080]

[0081] Among them, S rem is the remaining battery capacity, Smax is the maximum capacity of the battery, P real is the real-time power, P max is the maximum power.

[0082] In S205, the priority numbers of the charging piles are determined according to the priority standard values, and the charging piles are sorted in descending priority order.

[0083] The priority number i is a serial number value sorted from large to small according to Y in the power reduction strategy, and is numbered from 1. The larger the Y, the smaller the corresponding i value of the charging pile, and the smaller the i value, the higher the reduction priority of the charging pile.

[0084] In S207, a temporary variable p is defined.

[0085] After the priority ranking is completed, define a temporary variable p, and set p = 1. Go to S209 to determine whether p is equal to i max , if p is equal to i max , then S210 is performed to reduce the power of all charging piles that meet the conditions according to the preset control step, such as reducing the power by 1 step.

[0086] If p is not equal to i max , proceed to S211.

[0087] In S211, the predicted load factor is calculated.

[0088] Calculate the predicted load factor L pre_down_tem (p) is the transformer load rate of the first p piles in priority after a power reduction of one step, which is calculated as:

[0089]

[0090] Among them, L rate is the load factor of the distribution transformer, PF is the real-time power factor of the distribution transformer, S n is the transformer capacity, P sgset_i is the control step length P corresponding to the pile with priority number i sgset 、i max The priority number i corresponds to the pile with the lowest priority.

[0091] In S213, it is determined whether the predicted load factor is less than a load factor over-limit decrease threshold.

[0092] If the predicted load rate is less than the load rate over-limit drop threshold, the power of the first p charging piles in the priority ranking is reduced by 1 step;

[0093] If the predicted load rate is greater than the load rate over-limit drop threshold, then p = p + 1, and continue to determine whether p is equal to i max .

[0094] According to some embodiments, according to the power reduction strategy, the number k of charging piles to be regulated is determined as follows:

[0095] If L pre_down_tem (i max )>Sr down , then k=i max ;

[0096] If L pre_down_tem (p)≥Sr down And L pre_down_tem (p+1) <Sr down , p max , then k=p+1.

[0097] The control reduces the predicted load factor L pre_down is the expected load rate after this regulation, and its value is L pre_down_tem (k).

[0098] After the k value is determined, the intelligent fusion terminal in the substation area issues a control reduction command to reduce the power of the charging piles with a priority of 1 to k by one control step, and sets the power of the pile to (P set -P sgset ), after the setting is completed, enter the minimum cycle T waiting time, and after the waiting is completed, the next round of strategy execution will be carried out.

[0099] Figure 4 A flow chart for executing a power recovery strategy according to an example embodiment is shown.

[0100] The power recovery strategy is to orderly restore the output power of charging piles that have been reduced due to regulation.

[0101] In S301, it is determined whether there is a charging pile that meets the power recovery condition.

[0102] According to an exemplary embodiment, all charging piles that meet the power reduction condition are screened, wherein the power reduction condition includes the charging pile charging state St=1, the current P of the charging pile set <P n If there is no charging pile that meets the descending conditions, the process goes to S317, the power recovery strategy is terminated, and the system returns to the minimum control cycle T waiting time.

[0103] In S303, a priority standard value is calculated for the charging piles that meet the power reduction condition.

[0104] According to an exemplary embodiment, a priority standard value is calculated for a charging pile that meets the power reduction condition, and the priority standard value is used as a basis for regulating the charging pile. The priority standard value Y is calculated as follows:

[0105] ​

[0106] Among them, S rem is the remaining battery capacity, S max is the maximum capacity of the battery, P real is the real-time power, P max is the maximum power.

[0107] In S305, the priority number of the charging pile is determined according to the priority standard value, and the charging piles are prioritized.

[0108] The priority number i is a serial number value sorted from small to large according to Y in the power recovery strategy, starting from 1. The smaller the Y, the smaller the corresponding i value of the pile, and the smaller the i value, the higher the recovery priority of the pile.

[0109] In S307, a temporary variable p is defined.

[0110] After the priority ranking is completed, define a temporary variable p, and set p = 1. Go to S309 to determine whether p is equal to i max , if p is equal to i max , then S310 is performed to perform power recovery for all charging piles that meet the conditions according to a preset control step, such as 1 step of power recovery.

[0111] If p is not equal to i max , proceed to S311.

[0112] In S311, the predicted load factor is calculated.

[0113] Calculate the predicted load factor L pre_up_tem (p), calculated as:

[0114]

[0115] Among them, L rate is the load factor of the distribution transformer, PF is the real-time power factor of the distribution transformer, S n is the transformer capacity, P sgset_i is the control step length P corresponding to the pile with priority number i sgset 、i max The priority number i corresponds to the pile with the lowest priority.

[0116] In S313, it is determined whether the predicted load rate is greater than a load rate over-limit recovery threshold.

[0117] If the predicted load rate is greater than the load rate over-limit recovery threshold, the power of the charging pile ranked before (p-1) in priority order is restored by one step;

[0118] If the predicted load rate is less than or equal to the load rate over-limit recovery threshold, p=p+1 is set and the process returns to step S309 for determination.

[0119] According to some embodiments, according to the power recovery strategy, the number k of charging piles to be regulated is determined as follows:

[0120] If L pre_up_tem (i max ) <Sr up , then k=i max ;

[0121] If L pre_up_tem (p)≤Sr up And L pre_down_tem (p+1)>Sr up , p max , then k=p.

[0122] The control restores the predicted load factor L pre_up is the expected load rate after this regulation, and its value is L pre_up_tem (k).

[0123] After the k value is determined, the intelligent fusion terminal in the substation area issues a control recovery command to restore the power of the charging piles with a priority of 1 to k by one control step, and sets the power of the pile to (P set +P sgset ), after the setting is completed, enter the minimum cycle T waiting time, and after the waiting is completed, the next round of strategy execution will be carried out.

[0124] The present invention utilizes the orderly charging control method of the charging pile area, combined with the data parameters obtained in real time by the intelligent fusion terminal of the area, during the peak period of power grid load, by setting a reasonable load rate over-limit reduction threshold and the number of charging pile control gears, the power of the charging pile can be reduced in time to prevent overload and avoid power grid failure; during the low load period of the power grid, by setting a reasonable load rate over-limit recovery threshold, the power of the charging pile can be restored in time, and idle power resources can be fully utilized, thereby realizing efficient, reliable and safe charging management.
