Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In one embodiment, the charging pile charging protection method provided by the application can be applied to an application environment as shown in fig. 1. Specifically, the server 100 obtains the current power load of each power unit in the target area; the power utilization unit comprises a building power utilization unit and a charging pile power utilization unit; acquiring a preset electricity consumption threshold value of each electricity consumption unit; when the fact that the current power load exceeds a target power unit with a preset power threshold is monitored, a charging protection instruction is sent to a charging pile platform; the charging protection instruction is used for indicating the charging pile platform to reduce the current output power of the charging pile electricity utilization unit. The server 100 may be implemented as a stand-alone server or as a server cluster composed of a plurality of servers.
The server 100 may be any one or more physical servers or cloud servers of an EMS (Energy Management System ) platform, where the EMS platform is a modern integrated automation system for electricity use supported by computer technology and application software technology for electricity use, and is also an integrated or integrated system of an energy system and an information system. The target area may include areas of communities, shopping mall complexes, office buildings, hotels, and the like. The target area may include a plurality of electricity using units, and the plurality of electricity using units may include at least one building electricity using unit and at least one charging pile electricity using unit. The current power load may be monitored by the power distribution system and the server 100 may establish communication with the power distribution system. The server 100 may also establish communication with the charging pile platform to send charging protection instructions to the charging pile platform. The communication may be performed through a network, or may be performed by calling a hardware interface.
In one embodiment, as shown in fig. 2, a charging protection method for a charging pile is provided, and the method is applied to the server in fig. 1 for illustration, and may include the following steps:
step S202: acquiring the current power load of each power utilization unit in a target area; the power utilization unit comprises a building power utilization unit and a charging pile power utilization unit.
The target area refers to a selected area, and the target area may be any area configured with a new energy charging device, for example, may be various communities, residential areas, office areas, hotel areas, business areas, or the like. The target area may be divided into an electricity consumption area on the building side and an electricity consumption area on the charging pile side. The target area may include a plurality of power usage units therein. The electricity utilization unit can comprise at least one building electricity utilization unit and at least one charging pile electricity utilization unit. The electricity consumption unit on the building side can be used as the building electricity consumption unit, and the electricity consumption unit on the charging pile side can be used as the charging pile electricity consumption unit.
Illustratively, the building power usage unit may include at least one of a building lighting power usage unit, a public area lighting power usage unit, a garage slice power usage unit, a power elevator (main power usage) power usage unit, a power elevator (backup) power usage unit, a fan power usage unit, a main pump house power usage unit, a boiler house power usage unit, a spray pump power usage unit, a fire pump power (main power usage) power usage unit, a fire pump power (backup) power usage unit, a heat source pump power usage unit, an underground garage fan power usage unit, an air conditioner power usage unit, a bottom layer shop power usage unit, and a green area power usage unit.
For example, one charging pile power unit may be constituted by one charging pile, or may be constituted by a charging pile cluster including a plurality of charging piles.
In this step, the server may obtain the current power load of each power unit in the target area obtained by monitoring through the power distribution system by communicating with the power distribution system, that is, obtain the current power load of each building power unit on the building side and the current power load of each charging pile power unit on the charging pile side.
Step S204: and acquiring a preset electricity consumption threshold value of each electricity consumption unit.
The preset electricity consumption threshold value can be preset in advance in a self-defined mode according to service requirements, and can be comprehensively determined and set according to a predicted electricity consumption load trend curve of each electricity consumption unit, a transformer capacity threshold value of the whole target area and the like.
In this step, the server may acquire the electricity consumption threshold value configured in advance by the operator for each electricity consumption unit through the security policy configuration module of the EMS platform.
In one embodiment, the preset power usage threshold of each power usage unit may be determined according to the following method: acquiring historical electricity load data of each electricity unit; respectively predicting the power load trend of each power unit in a certain future time range according to each historical power load data; and respectively determining preset power consumption thresholds corresponding to the power consumption units according to the power consumption load trend and the transformer capacity threshold of the target area.
In this embodiment, data precipitation processing may be performed in advance on historical power load data of each building power unit on the building side and each charging pile power unit on the charging pile side, and after a data precipitation time sequence meets a preset period, a power load prediction model for different power units is respectively built by using a deep learning algorithm and a simulation algorithm. The preset period may be set by user-definition, for example, one day, one month, one year, etc.
Further, the power consumption load trend of each power consumption unit in a certain time in the future can be respectively simulated through the built power consumption load prediction model, and the power consumption threshold value of each power consumption unit is determined according to the curve of the power consumption load trend of each power consumption unit obtained through simulation prediction and by combining the total transformer capacity threshold value of the whole target area.
Illustratively, the server may utilize the following relationship based on a sum of the predicted electrical loads of the electrical units, for example: the sum of the electricity loads of all the electricity units (including all the building electricity units and the electricity units of the charging piles) is less than or equal to a preset coefficient (which can be between 0.2 and 0.3 or can be set according to service requirements) and less than or equal to the preset percentage (for example, 80%), so that the electricity threshold of all the electricity units can be determined.
For example, for the same power utilization unit, if the status, project or data collection time of the area where the power utilization unit is located is different, different power utilization value ranges are obtained. Taking an air conditioning unit as an example, if in an amateur state of a residential area, referring to fig. 3, fig. 3 shows a schematic diagram of a daily and annual electricity load trend curve of the air conditioning unit of the residential area in one embodiment. Fig. 3 (a) shows a trend of daily electrical loads of the air conditioning and power consuming unit in the residential area, and fig. 3 (b) shows a trend of annual electrical loads of the air conditioning and power consuming unit in the residential area. If referring to fig. 4 in the business state of the office building area, fig. 4 shows a schematic diagram of a daily and annual electricity load trend curve of an air conditioning unit in the office building area according to another embodiment. Fig. 4 (a) is a trend curve of daily electric loads of the air conditioner power unit in the office building area, and fig. 4 (b) is a trend curve of annual electric loads of the air conditioner power unit in the office building area.
As can be seen from fig. 3 to fig. 4, for the same kind of electricity consumption units, different electricity consumption load trend curves are obtained if the areas where the electricity consumption units are located have different states, different projects or different data acquisition times. Therefore, the historical electricity load data of each electricity consumption unit collected in different regional states, projects or different time intervals can be respectively used for predicting the electricity consumption load trend, so that the accuracy of setting the electricity consumption threshold value of each electricity consumption unit is improved, and the accuracy of charging pile charging protection can be further improved.
Step S206: when the fact that the current power load exceeds a target power unit with a preset power threshold is monitored, a charging protection instruction is sent to a charging pile platform; the charging protection instruction is used for indicating the charging pile platform to reduce the current output power of the charging pile electricity utilization unit.
The target electricity unit is an electricity unit whose current electricity load exceeds an electricity threshold preset for the target electricity unit, that is, an electricity unit in which an electricity abnormality occurs. The charging protection instruction is used for instructing a part or all of the charging pile platform to execute an instruction for reducing the current actual output power.
In this step, the server may monitor the power load status of each power unit in real time, and compare the power load value of each power unit monitored in real time with a preset power threshold of the power unit, so as to analyze whether the power unit is currently a target power unit with abnormal power consumption. Further, when it is detected that a target electricity unit with abnormal electricity consumption exists in the target area, the server can generate a charging protection instruction no matter whether the electricity unit is a building electricity unit at a building side or a charging electricity unit at a charging pile side, and the charging protection instruction is used for instructing the electric pile platform to reduce the current actual output power of all or part of the charging pile electricity units.
According to the charging pile charging protection method, the power consumption threshold value is set for each power consumption unit in the target area in advance, whether the current power consumption load of each power consumption unit exceeds the respective preset power consumption threshold value is monitored, and when the fact that the target power consumption unit exceeding the preset power consumption threshold value exists is monitored, the charging pile power consumption units in the target area are controlled to reduce the current actual output power of the charging pile power consumption units, so that on one hand, normal power supply of each building power consumption unit on the building side in the target area can be guaranteed preferentially, building outage caused by overload of a transformer is prevented, and on the other hand, charging pile charging accidents caused by power consumption conflicts can be prevented.
In one embodiment, the method further comprises: and when the target electricity utilization unit is a building electricity utilization unit, generating an alarm work order.
In this embodiment, the server may further analyze and determine whether the target electricity unit with electricity consumption abnormality belongs to a building electricity unit on a building side or a charging pile electricity unit on a charging pile side, and when determining that the target electricity unit is a building electricity unit on a building side, may further generate an alarm work order according to relevant information of the target electricity unit, for example, electricity consumption abnormality data information, electricity consumption unit position information, and/or electricity consumption abnormality cause information. The alarming work order is used for indicating the related responsible person of the target electricity utilization unit to conduct site investigation, manual intervention and other abnormal elimination measures.
In one embodiment, after generating the alert worksheet, the method further comprises: and sending the alarm work order to the target terminal.
In this embodiment, after the server generates the alert worksheet, the server may also send the generated alert worksheet to the target terminal by communicating with the target terminal, for example, by sending a short message, pushing a prompt message, or the like, so that an operator at the target terminal may perform maintenance work of the abnormal electricity consumption unit according to the indication of the alert worksheet. The target terminal may be any terminal that has previously established an association relationship with the server, and may include, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices.
In one embodiment, after generating the alert worksheet, the method further comprises: and displaying the alarming worksheet on a display interface in a pop-up window mode.
In this embodiment, after the server generates the alert worksheet, the alert worksheet may also be displayed in a pop-up window on a display interface of the display through an external display device, for example, a display, so that an operator using the display may timely see the alert worksheet, timely perform the promotion of a maintenance task, and improve the maintenance and management efficiency of each power unit.
In one embodiment, the method further comprises: if feedback information indicating that the current output power of the charging pile power utilization unit is successfully reduced, which is returned by the charging pile platform, is not received within the preset first time, the frequency of sending the charging protection instruction to the charging pile platform is increased.
In this embodiment, the first time may be set in a customized manner according to the service requirement, for example, may be set to 3 minutes, 5 minutes, or the like. After the server sends the charging protection instruction for indicating the charging pile platform to reduce the current output power of the charging pile power utilization unit to the charging pile platform, the server can read time, and in the preset first time, if feedback information of the charging pile platform is not received, that is, feedback information returned by the charging pile platform and used for successfully reducing the current output power of the charging pile power utilization unit is not received, the communication frequency between the server and the charging pile platform can be improved, for example, the originally set communication frequency is 1 time per minute, and the communication frequency can be improved to 1 time per 30 seconds and the like.
According to the embodiment, the possibility that the charging pile platform receives the charging protection instruction can be improved by improving the communication frequency of the server and the charging pile platform, so that the protection effect on the charging pile power utilization unit is further improved under the condition that abnormal power utilization occurs.
In one embodiment, the method further comprises: and if feedback information indicating that the current output power of the charging pile electricity utilization unit is successfully reduced, which is returned by the charging pile platform, is not received within the preset second time, starting backup protection measures. Alternatively, the backup protection may include shutting off power to some or all of the charging stake pocket.
In the present embodiment, a limit time threshold of the charge protection, that is, a second time, which may be set to be greater than the first time described above, for example, 10 minutes or the like may also be set in advance. If the server still does not receive the feedback information of the charging pile platform in the second time, the server can start the backup protection measure. In the second time, the server still does not receive the feedback information, so that the problem may occur in communication between the server and the charging pile platform, or the failure of the charging pile platform in reducing the output power of the charging pile power unit is likely to occur, at this time, the charging pile power unit still faces a dangerous hidden danger, which indicates that the current output power regulation means of the charging pile power unit by using the charging pile platform has failed, so that the backup protection measures can be started, the power supply of all or part of the charging pile power unit is directly controlled to be cut off by the server of the EMS platform, the backup protection function is achieved, and the charging pile charging safety is further improved.
Next, a charging pile charging protection method according to the present application will be further described with reference to fig. 5, where fig. 5 shows a schematic flow chart of the charging pile charging protection method in an application example. The method specifically comprises the following steps:
and 1, monitoring the power load of each power utilization unit. Specifically, the server may obtain the current electricity loads of the electricity units on the building side and the charging pile side by communicating with the power distribution system.
And 2, analyzing the load according to a preset electricity consumption threshold. Specifically, the server may analyze whether the electricity consumption unit is abnormal according to a preset electricity consumption threshold of the electricity consumption unit.
Step 3, whether a target electricity utilization unit with the current electricity utilization load larger than a preset electricity utilization threshold exists or not is analyzed by the server, if yes, the step 4 is entered; if not, returning to the step 1.
And 4, sending a charging protection instruction. Specifically, the server may send a charging protection instruction to the charging pile platform, so that the charging pile platform controls the charging pile power unit to reduce the current output power according to the charging protection instruction after receiving the charging protection instruction. Further, if the target electricity utilization unit is a building electricity utilization unit, the server can also generate an alarm work order and push the alarm work order to a terminal registered by related operators.
Step 5, the server receives feedback information indicating that the charging pile platform returns to successfully control the charging pile power utilization unit to reduce the current output power or not in a preset first time, and if yes, the step 1 is returned; if not, go to step 6.
And step 6, the communication frequency for sending the charging protection instruction is increased. Specifically, the server may tune up the frequency of the current communication interactions with the charging pile platform.
