Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In an embodiment, the charging protection method for the charging pile 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 consumption 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 utilization threshold value of each electricity utilization unit; when the target power utilization unit with the current power utilization load exceeding a preset power utilization threshold value is monitored, a charging protection instruction is sent to a charging pile platform; wherein, the protection instruction that charges is used for instructing and fills electric pile platform and reduce the current output who fills electric pile power consumption unit. The server 100 may be implemented as a stand-alone server or 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 power utilization supported by a computer technology and a power utilization System application software technology, and is also an integrated System of an Energy System and an information System. The target area may include areas of a community, a shopping mall complex, an office building, a hotel, etc. The target area may include a plurality of power consumption units, and the plurality of power consumption units may include at least one building power consumption unit and at least one charging pile power consumption unit. The current electrical 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 above communication may be performed through a network, or may be realized by calling a hardware interface.
In an embodiment, as shown in fig. 2, a charging protection method for a charging pile is provided, which is described by taking the method as an example applied to the server in fig. 1, and may include the following steps:
step S202: acquiring the current power load of each power consumption unit in a target area; wherein, the power consumption unit includes building power consumption unit and fills electric pile power consumption unit.
The target area refers to a selected area, and may be any area where the new energy charging apparatus is disposed, for example, various communities, residential areas, office areas, hotel areas, or business areas. The target area may be divided into a power consumption area on the building side and a power consumption area on the charging pile side. The target area may include a plurality of power consuming units therein. The power utilization units can comprise at least one building power utilization unit and at least one charging pile power utilization unit. The power consumption unit on the building side can be used as the power consumption unit for the building, and the power consumption unit on the charging pile side can be used as the power consumption unit for the charging pile.
Illustratively, the building electricity utilization unit may include at least one of a building lighting electricity utilization unit, a public area lighting electricity utilization unit, a garage district electricity utilization unit, a power elevator (primary) electricity utilization unit, a power elevator (standby) electricity utilization unit, a fan electricity utilization unit, a master pump house electricity utilization unit, a boiler house electricity utilization unit, a spray pump power electricity utilization unit, a fire pump power (primary) electricity utilization unit, a fire pump power (standby) electricity utilization unit, a heat source pump power electricity utilization unit, an underground garage fan electricity utilization unit, an air conditioning electricity utilization unit, a bottom layer shop electricity utilization unit, and a greening area electricity utilization unit.
For example, one charging pile electricity consumption unit may be composed of one charging pile, or may be composed of a charging pile cluster including a plurality of charging piles.
In this step, the server may obtain the current power load of each power consumption unit in the target area monitored by the power distribution system by communicating with the power distribution system, that is, obtain the current power load of each building power consumption unit on the building side and the current power load of each charging pile power consumption unit on the charging pile side.
Step S204: and acquiring a preset electricity utilization threshold value of each electricity utilization unit.
The preset power utilization threshold value can be set in a user-defined mode in advance according to business requirements, and can also be determined and set comprehensively according to predicted power utilization load trend curves of all power utilization units, transformer capacity threshold values of the whole target area and the like.
In this step, the server may obtain the power utilization threshold value that the operator previously configured for each power utilization unit through the security policy configuration module of the EMS platform.
In one embodiment, the preset power utilization threshold of each power utilization 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 time range in the future according to the historical power load data; and respectively determining the preset power utilization threshold corresponding to each power utilization unit according to the power utilization load trend and the transformer capacity threshold of the target area.
In this embodiment, data precipitation processing may be performed 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 in advance, and when the data precipitation time sequence satisfies a preset period, power load prediction models for different power units are respectively established by using a deep learning algorithm and a simulation algorithm. The preset period can be set by self-definition, for example, one day, one month, one year, and the like.
Furthermore, the power utilization load trend of each power utilization unit within a certain time in the future can be simulated through the established power utilization load prediction models, and the power utilization threshold value of each power utilization unit is determined according to the power utilization load trend curve of each power utilization unit obtained through simulation prediction and by combining the total transformer capacity threshold value of the whole target area.
For example, the server may use the following relation according to the sum of the predicted power loads of the power consumption units: the sum of the power loads of all power utilization units (including all building power utilization units and charging pile power utilization units) is equal to or less than a preset percentage (for example, 80%) and can be set to be between 0.2 and 0.3 or according to business requirements, so that the power utilization threshold of each power utilization unit can be determined.
For example, for the same electricity utilization unit, if the state, project or data collection time of the area where the electricity utilization unit is located is different, different electricity utilization value ranges are obtained. Taking an air conditioning electric unit as an example, referring to fig. 3 in the state of a residential area, fig. 3 shows a schematic diagram of a daily and annual electric load trend curve of the air conditioning electric unit in the residential area in one embodiment. Fig. 3 (a) is a trend curve of the daily power load of the air-conditioning power unit in the residential area, and fig. 3 (b) is a trend curve of the annual power load of the air-conditioning power unit in the residential area. Referring to fig. 4, fig. 4 is a schematic diagram illustrating a daily and annual power load trend curve of an air conditioning power unit in an office building area according to another embodiment. Fig. 4 (a) is a trend curve of the daily power load of the air conditioning power units in the office building area, and fig. 4 (b) is a trend curve of the annual power load of the air conditioning power units in the office building area.
As can be seen from fig. 3 to 4, for the same type of electricity consumption unit, if the status, project or data collection time of the area where the electricity consumption unit is located is different, different electricity consumption load trend curves are obtained. Therefore, the power load trend can be respectively predicted according to the historical power load data of each power consumption unit collected in different regional statuses, projects or different time intervals, so that the accuracy of setting the power consumption threshold of each power consumption unit is improved, and the accuracy of charging protection of the charging pile can be further improved.
Step S206: when the target power utilization unit with the current power utilization load exceeding a preset power utilization threshold value is monitored, a charging protection instruction is sent to a charging pile platform; wherein, the protection instruction that charges is used for instructing and fills electric pile platform and reduce the current output who fills electric pile power consumption unit.
The target electricity utilization unit is an electricity utilization unit of which the current electricity utilization load exceeds a preset electricity utilization threshold, that is, an electricity utilization unit with electricity utilization abnormality. The charging protection instruction is an instruction for instructing a charging pile platform to control part or all of charging pile electricity utilization units to execute and reduce the current actual output power.
In this step, the server may monitor the power load state of each power consumption unit in real time, and compare the power load value of each power consumption unit monitored in real time with a preset power consumption threshold of the power consumption unit, so as to analyze whether the power consumption unit is a target power consumption unit with power consumption abnormality. Furthermore, when the target electricity utilization unit with abnormal electricity utilization exists in the monitored target area, the server can generate a charging protection instruction no matter whether the electricity utilization unit is a building electricity utilization unit on the building side or a charging electricity utilization unit on the charging pile side, and the current actual output power of all or part of the charging pile electricity utilization units is reduced through the charging protection instruction by indicating the electricity pile platform.
According to the charging protection method for the charging pile, the electricity utilization threshold values are set for the electricity utilization units in the target area in advance, whether the current electricity utilization loads of the electricity utilization units exceed the respective preset electricity utilization threshold values is monitored, and when the target electricity utilization units exceeding the preset electricity utilization threshold values are monitored, the charging pile electricity utilization units in the target area are preferentially controlled to reduce the current actual output power of the charging pile electricity utilization units, so that on one hand, the normal power supply of the building electricity utilization units on the building side in the target area can be preferentially ensured, building power failure caused by transformer overload is prevented, and on the other hand, charging accidents of the charging pile caused by electricity utilization conflicts can be prevented.
In one embodiment, the method further comprises: and when the target power utilization unit is a building power utilization unit, generating an alarm work order.
In this embodiment, the server may further analyze and determine whether the target electricity utilization unit with the electricity utilization abnormality is a building electricity utilization unit on the building side or a charging pile electricity utilization unit on the charging pile side, and when it is determined that the target electricity utilization unit is the building electricity utilization unit on the building side, may further generate an alarm work order according to relevant information of the target electricity utilization unit, for example, electricity utilization abnormality data information, electricity utilization unit position information, and/or electricity utilization abnormality cause information. The alarm work order is used for indicating relevant responsible persons of the target power utilization unit to carry out on-site investigation, manual intervention and other abnormal elimination measures.
In one embodiment, after generating the alarm work order, the method further comprises: and sending the alarm work order to a target terminal.
In this embodiment, after the server generates the alarm work order, the server may further communicate with the target terminal, for example, by sending a short message, pushing a prompt message, or the like, to send the generated alarm work order to the target terminal, so that an operator at the target terminal may perform maintenance work on the abnormal power consumption unit according to an instruction of the alarm work order. The target terminal may be any one of terminals that have 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 alarm work order, the method further comprises: and displaying the alarm work order on a display interface in a pop-up window mode.
In this embodiment, after the alarm work order is generated by the server, the alarm work order may be displayed in a display interface of the display in a pop-up window form through an external display device, such as a display, so that an operator using the display can see the alarm work order in time, advance a maintenance task in time, and improve maintenance and management efficiency of each power utilization unit.
In one embodiment, the method further comprises: if feedback information which is returned by the charging pile platform and represents that the current output power of the charging pile power utilization unit is successfully reduced is not received within the preset first time, the frequency of sending a charging protection instruction to the charging pile platform is increased.
In this embodiment, the first time may be set to be customized according to the service requirement, for example, may be set to be 3 minutes, 5 minutes, and the like. The server has sent the protection instruction of charging that is used for instructing to fill the electric pile platform and reduces the current output who fills electric pile electricity consumption unit to filling the electric pile platform after, can carry out the time and read, in the very first time of predetermineeing, if, the feedback information who fills the electric pile platform is not received, namely, the feedback information who has successfully reduced the current output who fills electric pile electricity consumption unit that the electric pile platform returned is not received, can improve the communication frequency between server and the electric pile platform of filling, for example, the communication frequency that originally sets up is 1 time per minute, can improve to 1 time per 30 seconds etc..
This embodiment, through the communication frequency who improves server and fill electric pile platform, can improve and fill electric pile platform and receive the possibility of charging protection instruction to, under the condition that the unusual power consumption takes place, further improve the protection efficiency to filling electric pile power consumption unit.
In one embodiment, the method further comprises: and if the feedback information which is returned by the charging pile platform and represents that the current output power of the charging pile power utilization unit is successfully reduced is not received within the preset second time, starting a backup protection measure. Optionally, the backup protection measure may include cutting off power to some or all of the charging post power consumption units.
In this embodiment, a limit time threshold of the charging protection may also be preset, that is, a second time, which may be set to be greater than the first time, may be 10 minutes, for example. If the server still does not receive the feedback information of the charging pile platform within the second time, the server can start a backup protection measure. The server still does not receive feedback information within the second time, then probably the server and the communication between the platform of charging pile go wrong, or it reduces the output power failure who fills electric pile power consumption unit to fill electric pile platform, at this moment, it still faces dangerous hidden danger still to fill electric pile power consumption unit, it is out of order to explain the regulation and control means that utilizes the current output power that fills electric pile power consumption unit to fill electric pile platform, therefore, backup protection measures can be launched, the power of whole or partial electric pile power consumption unit is filled in the server direct control through the EMS platform cut off, play the effect of backup protection, further improve the security that fills electric pile and charge.
