The invention provides a dynamic regulation and control method of charging power, which is applied to a charging system with a plurality of charging devices. In this embodiment, the charging system is a centralized charging station, and is used for simultaneously charging a batch of electric vehicles; the charging device is an independent device for charging the electric vehicle, and is specifically provided with a plurality of charging or charging sockets.
The charging system further comprises power supply equipment, power acquisition equipment and power regulation and control equipment. The power supply equipment and each intelligent charging equipment are respectively connected with the power acquisition equipment in a wired or wireless mode, and the power regulation and control equipment is respectively connected with each intelligent charging equipment and the power acquisition equipment in a wired or wireless mode.
The power supply equipment is connected with the social power supply system and transmits the electric energy of the social power supply system to the charging equipment. The power supply equipment provides power for a charging system, and the rated power of the power supply equipment is the rated power of the charging system.
The maximum rated power of each charging device is p1, the minimum output power is p2, and the output power of each charging device is set to be dynamically adjustable between p2 and p 1. Specifically, according to the mechanism defined in GB/T18487.1-2015, the ac charging post may notify the maximum power supply current of the power supply device to the electric vehicle using the PWM signal. The standard definition of the PWM signal versus supply current limit has a expressive power of at least 6A (at 220V, the supply power ≈ 1.3 KW). The platform can control and fill electric pile, sends and represents arbitrary PWM signal between 1.3KW ~ 7KW power. And the vehicle-mounted charger of the electric vehicle identifies and responds to the signal to adjust the charging power.
In another embodiment, the charging system has two sizes of charging devices, one is a power adjustable charging device, such as a charging socket set to a 7-hole output; another is a charging device that is not power adjustable, such as a charging socket set to a 3-hole output.
In order to maximize the utilization rate of the power supply device, in this embodiment, the maximum total output power of the charging device is greater than or equal to the rated power of the power supply device, that is, when all the intelligent charging devices are in the charging state, the total output power of all the charging devices is greater than or equal to the maximum rated output power of the power supply, so that the requirement of setting a greater number of charging devices 20 for charging more users at the same time can be met. However, when a large number of intelligent charging devices are charged simultaneously, the total output power is at a large value, which is close to or exceeds the rated power of the power supply device, and thus, large pressure is applied to the power supply device and the power supply line. Therefore, in order to satisfy the charging requirements of a large number of users and the requirement of keeping the load of the power supply device in a relatively stable range, the output power of the charging device needs to be adjusted.
The power acquisition equipment is used for acquiring and monitoring real-time charging data of the charging system, and the power acquisition equipment can monitor the output power of each charging equipment in real time. Specifically, the real-time output power of the charging system is the output power of each charging device in the charging state in the real-time state. In this embodiment, the power acquisition device may acquire real-time charging data of the charging device and transmit the real-time charging data to the power regulation device. In other embodiments, the power collecting device may further collect the accumulated output power of the charging device; or the power acquisition equipment can also acquire the charging remaining time of the corresponding automobile through the charging equipment; alternatively, the power collection device may also collect a charge start time of the charging device.
The power regulation and control equipment is used for receiving the system real-time output power collected by the power collection equipment, and according to the system real-time output power condition, the total output power of the charging equipment is further adjusted by respectively dynamically adjusting the output power of each intelligent charging equipment, so that the system load factor is kept in a relatively stable range.
Referring to fig. 1, a schematic flow chart of a charging power dynamic regulation method according to a first embodiment of the present invention is shown, and the method includes the following steps:
step S110, acquiring real-time charging data, determining a load rate according to the real-time charging data, and comparing the load rate with at least one preset threshold value;
step S120, when the load rate is higher than at least one preset threshold value, determining the adjustable reduction power according to the real-time charging data;
and S130, sequencing the adjustable reduction power to form a first sequence, and reducing the output power according to the first sequence.
The charging real-time data comprises real-time output power of the charging equipment and rated power of the power supply equipment, and the load rate is a ratio of the real-time total output power of the charging equipment to the rated power of the power supply equipment. The adjustable power reduction is a charging device with adjustable power in a charging system, and the adjustable power reduction is realized when the real-time output power is greater than the minimum output power. The adjustable reducing power is sequenced to form a first sequence, the first sequence is actually sequenced according to the size of the adjustable reducing power of the corresponding charging equipment,
the method comprises the steps of determining the load rate of a charging system, judging whether the load rate meets a preset condition, determining charging equipment capable of achieving power adjustment in the charging system when the load rate meets the preset condition, sequencing the adjustable charging equipment and performing power adjustment and reduction according to a sequence, so that the purpose of reducing the output power of the charging system is achieved, and the load rate is stabilized. Specifically, the charging system is configured to perform a power down operation when the load rate exceeds 90%.
Further, the at least one preset threshold includes a first preset threshold and a second preset threshold, wherein the first preset threshold is greater than the second preset threshold; when the load rate is higher than the first preset threshold, output power is adjusted down in batch according to the first sequence; and when the load rate is higher than the second preset threshold and lower than the first preset threshold, sequentially regulating and reducing the output power according to the first sequence.
The first preset threshold and the second preset threshold divide the range of the load rate of the charging system into a plurality of intervals, the first load interval is larger than the first preset threshold, the second load interval is larger than the second preset threshold and smaller than the first preset threshold, and when the load rate is monitored to be in a higher range value, batch adjustment and reduction operation is started; when the load rate is monitored to be in the next highest range value, the individual regulating operation is started. In this way, a more rapid adjustment of the load factor for high loads is effectively achieved. Specifically, the charging system is configured to perform a power batch step-down operation when the load rate exceeds 95%, and perform an individual step-down operation when the load rate is between 90% and 95%.
Further, the first sequence is set to a plurality of continuous sections, wherein the output power is adjusted and reduced in batches from the first section according to the first sequence, and the adjustment and reduction values in the same section are the same; or, the output power is sequentially regulated and reduced from the first bit according to the first sequence, and the regulation and reduction values in the same interval are the same.
Specifically, the sorting rule of the first sequence is based on one of the real-time output power, the charging start time, the charging amount, or the charging remaining time of the charging device, for example, the real-time output power is sorted from large to small, the out-of-point start time is sorted from first to last, the charging amount is sorted from large to small, or the charging remaining time is sorted from large to small.
Further, the down-regulated output power is sequentially reduced from the first section.
A first sequence of segments formed by sequencing according to the rules is segmented, for example, the segment interval of the real-time output power is set to be 5-7 KW, 3-5 KW and 1.3-3 KW, wherein the adjustable charging equipment with the real-time output power in the range of 5-7 KW has the power of 3KW correspondingly adjusted and reduced during adjustment and reduction; the adjustable charging equipment with real-time output power in the range of 3 KW-5 KW has the power of 2KW corresponding to the adjustment during adjustment and reduction; the adjustable charging equipment with real-time output power within the range of 1.3 KW-3 KW is adjusted to be lowered by 1KW when being adjusted to be lowered. The output power of the conditional charging equipment with the real-time output power less than 2.3KW is correspondingly adjusted to 1.3KW (the minimum output power of the charging equipment).
Further, the load rate is compared with a preset threshold to judge whether a preset turn-down condition is met, whether the load rate exceeds the at least one preset threshold for a first preset time is judged, for example, whether the load rate exceeds 95% to reach 20 minutes, if yes, the judgment condition is met, and the next operation is carried out.
Therefore, the charging system can be accurately regulated and controlled, and unnecessary regulation caused by temporary load transient increase of the charging system is avoided.
And further, determining whether the charging equipment is the adjustable charging equipment or not according to the judgment of the real-time output power and the minimum output power of the charging equipment. And when the real-time output power of the charging equipment is greater than the minimum output power, the charging equipment is the adjustable drop charging equipment.
Further, referring to fig. 2, step S130 includes the sub-steps of:
step S131, acquiring the real-time output power and the minimum output power of the charging equipment, and determining the charging equipment with the real-time output power larger than the minimum output power as the adjustable charging equipment;
step S132, sequencing according to the real-time charging data of the adjustable charging equipment to form a first sequence;
and step S133, the output power of the charging equipment is adjusted and reduced according to the first sequence.
After the adjustable charging equipment is determined, sorting is carried out according to the real-time charging data of the adjustable charging equipment, and the adjustable charging equipment is adjusted and lowered, so that accurate flexible power regulation and control of the charging equipment are realized, and the stability of the load rate of a charging system is maintained.
Further, after the charging device is adjusted and lowered, the real-time charging data of the charging device is continuously monitored, and the method further comprises a step S140, wherein after the adjustment and lowering are completed, when the load rate is higher than a third preset threshold value; s150, sequencing according to the real-time charging data to form a second sequence, and executing shutdown operation according to the second sequence; wherein the third preset threshold is smaller than the at least one preset threshold.
Specifically, when the adjustable equipment is adjusted and lowered, the real-time output power reaches the minimum value of 1.3KW after the charging equipment is adjusted and lowered; the third preset threshold is set to 80%. In practice, when the output power of all the local adjustable charging devices is adjusted to be reduced to the minimum value and the current load rate is still in a higher state and is higher than 80%, at this time, the output power of all the local adjustable charging devices is sorted according to the real-time charging data of the charging devices to form a second sequence, and the shutdown operation is executed according to the second sequence.
Further, the rule forming the second sequence is similar to the rule forming the first sequence, wherein the real-time output powers of a large number of charging devices after the adjustment and the reduction are all in the same minimum state, and the sorting rule does not include sorting according to the real-time output powers, but according to the charging start time, the charging electric quantity or the charging remaining time, and specific sorting rules are not repeated.
Further, shutdown operation is executed according to the second sequence, and shutdown is stopped when the load rate is lower than a third preset threshold.
Specifically, after the charging device is shut down, when the load rate reaches 80% or less, it is determined that the current load rate of the system is stable, and power regulation is stopped.
And further, stopping the shutdown when the load rate is lower than a third preset threshold and exceeds a second preset time. Specifically, in order to more accurately judge the stability of the system load rate, the judgment trigger condition is set such that the load rate reaches 80% or less and lasts for 30 minutes.
Further, in the regulating and descending process, after the output power is regulated and reduced according to the first sequence, the load rate is lower than a third preset threshold value, and the regulating and descending is stopped. Specifically, during the charging system performs the step-down operation on the charging device according to the first sequence, the load factor of the system is adjusted to a stable range, for example, less than 80%, that is, the step-down operation on the charging device is stopped. It will be appreciated that the triggered adjustment of the turn-down stop may also be arranged to determine that the load rate is less than 80% for a second predetermined period of time, for example 30 minutes.
Further, after the adjustment and the reduction are stopped or the shutdown is stopped, when the load rate is in a lower range and continues for a second preset time, it is determined that the adjustment and the increase of the charging equipment are needed.
Specifically, the method further includes step S160, when the load factor is lower than a third preset threshold or a fourth preset threshold; step S170, sequencing the adjustable-lift charging equipment to form a third sequence, and adjusting and lifting the output power according to the third sequence; wherein the fourth preset threshold is smaller than the third preset threshold.
And when the load rate is smaller than a third preset threshold or the fourth preset threshold exceeds a second preset time, for example, less than 70% or 80% exceeds 30 minutes, it is determined that the charging equipment needs to be lifted, and the utilization rate of the charging system is improved.
After the boost operation, if the load factor of the charging system is still in a low state, for example, a large number of charging devices with constant output are in a charging state and a small number of adjustable charging devices are in a working state, the start operation may be performed after the boost operation, and the charging device connected with the charging vehicle but not working may be turned on. In this embodiment, the power regulation and control priority is adopted for the boost operation, so that flexible regulation and control are realized, and the impact on the charging equipment and the circuit is reduced. It can be understood that, in other embodiments, when it is determined that the load factor is in the lower range value and the output power of the system needs to be regulated and controlled to be increased, sequential regulation may be adopted, that is, a turn-down sequence, a power change value, and a turn-off sequence are recorded, and corresponding operations are performed on the charging device according to the above sequence, for example, the charging device is turned on according to the turn-off sequence, and then the device is turned up according to the turn-down sequence.
Further, the real-time charging data includes real-time output power and maximum power limit of the charging device, wherein the charging device with the maximum output power larger than the real-time output power is an adjustable charging device.
Further, referring to fig. 3, in the step S170, the step of sequencing the adjustable boost charging device to form a third sequence, and the step of increasing the output power according to the third sequence includes the sub-steps of:
step S171, acquiring the real-time output power and the maximum output power of the charging equipment, and determining the charging equipment with the real-time output power smaller than the maximum output power as the adjustable charging equipment;
step S172, sequencing according to the real-time charging data of the lifting-adjustable charging equipment to form a third sequence;
step S173, the output power of the boost-adjustable charging device is boosted according to the third sequence.
After the adjustable-lift charging equipment is determined, sequencing is carried out according to the real-time charging data of the adjustable-lift charging equipment, and the adjustable-lift charging equipment is subjected to lifting adjustment operation, so that accurate flexible power regulation and control of the charging equipment are realized, and the load rate of a charging system is maintained to be stable.
Specifically, the sorting rule of the third sequence is based on one of the real-time output power, the charging start time, the charging amount, or the charging remaining time of the charging device, for example, the real-time output power is sorted from small to large, the out-of-point start time is sorted from back to first, the charging amount is sorted from small to large, or the charging remaining time is sorted from small to large.
It can be understood that the dynamic regulation and control method of the charging power provided by the invention can also be applied to a scene of preferentially regulating and increasing the output power when the load rate is lower. When the lifting trigger value is judged, the flexible lifting operation is executed firstly, and then the charging equipment starting operation is executed.

when the load rate is higher than a second preset threshold; determining adjustable descending equipment according to the real-time charging data, sequencing the adjustable descending equipment to form a first sequence, and adjusting and descending the output power according to the first sequence; wherein the second preset threshold is greater than the third preset threshold.
