Specifically, the server 100 obtains the current total power load of all power consumption units in the target area; the system comprises a target area, a server 100, a charging pile platform and a charging pile, wherein the target area comprises a building power utilization unit on a building side and a charging pile power utilization unit on a charging pile side, the server 100 compares the current total power utilization load with a first early warning value, when the current total power utilization load is smaller than the first early warning value, the current total power utilization load is compared with a second early warning value, and when the current total power utilization load is larger than the second early warning value, the server 100 indicates the charging pile platform to reduce the power utilization capacity threshold value of the charging pile power utilization unit. The server 100 may be implemented as an independent 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 power load data of each power utilization unit can be monitored through a power distribution system, and the server 100 can be communicated with the power distribution system. The server 100 may also establish communication with the charging pile platform to send instructions to the charging pile platform instructing it to adjust the power usage capacity threshold of the charging pile power consumption units. 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 method for adjusting the power capacity of 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 total power load of all power utilization units in a target area; the target area comprises a building power utilization unit on the building side and a charging pile power utilization unit on the charging pile side.
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, in real time, the current power consumption 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 consumption load of each building power consumption unit on the building side and the current power consumption load of each charging pile power consumption unit on the charging pile side. Further, the server may perform superposition calculation on the obtained current power loads of the power consumption units to obtain the current total power loads of all the power consumption units.
Step S204: and comparing the current total power load with a first early warning value.
The first early warning value is an early warning limit value used for indicating whether manual intervention or maintenance is needed in the target area. The first warning value may be set in advance through the EMS platform, and the operator may perform custom setting according to a transformer capacity threshold of the entire target area, for example, the first warning value may be determined by multiplying the transformer capacity threshold by a preset percentage (e.g., 80%, 90%, or 95%).
In this step, the server may compare the current total power loads of all the power consumption units obtained and calculated in real time with the preset first warning value, so as to determine whether the total power loads of all the power consumption units in the target area exceed the preset first warning value at the current time point or in the current time period.
Step S206: and when the current total power load is smaller than the first early warning value, comparing the current total power load with a second early warning value.
And the second early warning value is used for indicating whether the target area needs to be dynamically adjusted in power utilization capacity. The second warning value may also pass through the EMS platform in advance, and the operator may perform custom setting according to the transformer capacity threshold of the entire target area, and the second warning value may be set to be smaller than the first warning value, for example, if the first warning value is set to 90% of the transformer capacity threshold, the second warning value may be set to 80% of the transformer capacity threshold, and so on.
In this step, after the server determines that the current total power load of all power consumption units in the target area is smaller than the preset first warning value, the server may continue to compare the current total power load with the preset second warning value. If the current total power load is larger than the second early warning value, it can be shown that the target area is in the power utilization peak period at the current time point or in the current time period, power utilization conflicts may occur among the power utilization units, and the whole target area may have power utilization potential safety hazards to a certain extent. If the current total power load is smaller than the second early warning value, it can be shown that the target area is in the power utilization valley period at the current time point or time period, the probability of power utilization conflict among the power utilization units is small, and idle power capacity may exist in the whole target area to a certain extent.
Step S208: when the current total power load is larger than the second early warning value, the charging pile platform is instructed to reduce the power consumption capacity threshold of the charging pile power consumption unit.
The charging pile platform is a platform for managing or controlling a charging pile electricity utilization unit.
In this step, when the server determines that the current total power load of all power consumption units in the target area is greater than the second early warning value, it indicates that the power consumption peak period is in the target area at the current time point or in the time period, power consumption conflicts may occur among the power consumption units, and power consumption potential safety hazards may exist in the whole target area to a certain extent.
According to the method for adjusting the power consumption capacity of the charging pile, the power consumption loads of all power consumption units in a target area are monitored, the first and second dual early warning values are set, the current total power consumption load of each power consumption unit monitored in real time is compared with the first and second early warning values respectively, when the current total power consumption load is smaller than the first early warning value and larger than the second early warning value, the charging pile platform is indicated to reduce the power consumption capacity threshold value of the power consumption unit of the charging pile on the charging pile side, so that the normal power supply of the power consumption unit of the building on the building side can be preferentially ensured in the peak period of power consumption with more tense power consumption capacity of the whole target area, and the power consumption unit of the charging pile is prevented from influencing the normal power consumption of the building side.
In one embodiment, the method further comprises: when the current total power load is smaller than the second early warning value, the charging pile platform is instructed to increase the power consumption capacity threshold of the charging pile power consumption unit.
In this embodiment, when the server determines that the current total power load of all power consumption units in the target area is smaller than the second warning value, it indicates that the target area is in a power consumption valley period at the current time point or in the current time period, the probability of power consumption conflict among the power consumption units is small, and idle power capacity may exist in the whole target area to a certain extent.
This embodiment, when current total power consumption load is less than the second early warning value, instruct through the server that to fill the electric pile platform with the electric capacity threshold value increase of the electric unit of filling of electric pile side, thereby can be in the power consumption valley period of whole target area, when the building power unit of ensureing the building side can normally supply power, also enable to fill the electric pile power unit make full use of the idle electric quantity in the target area, thereby can be under the condition that does not influence building side power consumption, improve the utilization ratio of filling electric pile and the utilization ratio of the electric power resource of whole target area, satisfy the demand of charging of growing new energy automobile.
In one embodiment, the method further comprises: and when the current total power load is greater than the first early warning value, determining a target power utilization unit with abnormal power, and generating warning information according to the target power utilization unit.
In this embodiment, the server monitors that an abnormal power utilization condition occurs in the target area, and under the abnormal power utilization condition, the server determines that the current total power utilization load of each power utilization unit in the target area is greater than a preset first early warning value. In this case, the server may analyze the abnormal power consumption, determine which power consumption unit or units have abnormal power consumption by analysis, and set the determined power consumption unit having abnormal power consumption as the target power consumption unit. Further, the server may obtain relevant information of the determined target power consumption unit, such as position information, abnormal data information, associated operator information, and the like, and generate alarm information according to the relevant information of the target abnormal unit, so as to indicate that the relevant operator can perform manual intervention and maintenance on the target power consumption unit according to the alarm information.
In this embodiment, when the current total power load is greater than the preset first warning value, it indicates that the power consumption in the target area exceeds the safety critical value, and at this time, the transformer in the target area may be overloaded, and needs to be manually intervened, maintained or take other protective measures in time, so that the power consumption risk can be timely removed, and the power consumption safety of the whole area can be improved.
In one embodiment, after generating the alarm information according to the target electricity usage unit, the method further includes: and sending the alarm information to the target terminal.
In this embodiment, after the server generates the alarm information, the server may further send the generated alarm information to the target terminal through communication with the target terminal, for example, in the form of sending a short message, pushing a prompt message, or the like, so that an operator at the target terminal may perform maintenance and other work on the abnormal power consumption unit according to the indication of the alarm information. 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 information according to the target electricity usage unit, the method further includes: and displaying the alarm information on a display interface in a pop-up window mode.
In this embodiment, after the server generates the alarm information, the server may further display the alarm information in a display interface of the display in a form of a pop-up window through an external display device, such as a display, so that an operator using the display can see the alarm information in time, advance a maintenance task in time, and improve maintenance and management efficiency of each power consumption unit.
In one embodiment, after generating the alarm information according to the target electricity usage unit, the method further includes: and starting a backup protection measure.
Optionally, the backup protection measure may include directly controlling, by a server of the EMS platform, to cut off a power supply of part or all of the charging pile power consumption units; or, when the target electricity utilization unit is a charging pile electricity utilization unit, directly controlling to cut off the power supply of the target electricity utilization unit through a server of the EMS platform.
According to the embodiments, when the current total power load exceeds the preset first warning value, the current power consumption of the whole target area exceeds the limit value, in this case, both the building power consumption unit on the building side and the charging pile power consumption unit on the charging pile side may face the potential safety hazard caused by the overload of the transformer. Therefore, the electricity safety in the whole target area can be improved by means of sending and popping alarm information and/or starting backup protection and the like.
In one embodiment, after instructing the charging post platform to lower the power usage capacity threshold of the charging post power unit, the method further comprises: and the indication charging pile platform reduces the output power of all and/or part of the charging pile power consumption units according to the lowered power consumption capacity threshold of the charging pile power consumption units.
In this embodiment, the server of the EMS platform may further instruct the charging pile platform to correspondingly reduce the output power of all or part of the charging pile power consumption units according to the lowered power consumption capacity threshold of the charging pile power consumption units. The strategy for adjusting the output power of the charging pile power utilization unit can be set according to business requirements.
Illustratively, the server may instruct the charging pile platform to uniformly reduce the output power of each charging pile power unit. Referring to fig. 3, fig. 3 is a schematic diagram illustrating an embodiment of indicating charging pile platforms to uniformly adjust output power of each charging pile electricity consumption unit. Specifically, if 4 charging pile power consumption units (charging piles) are included in the target area, the maximum output power of each charging pile power consumption unit is 7kW, and the power consumption threshold value after the reduction is 21kW, the output power of each charging pile power consumption unit can be uniformly adjusted under the condition that the total output power of the 4 charging pile power consumption units does not exceed 21 kW. For example, the output power of 21kW may be equally distributed to 4 charging pile power consumption units, and each charging pile power consumption unit may control the output power to 75% of the maximum output power of 7kW, that is, 5.25 kW.
For example, the server may instruct the charging pile platform to preferentially reduce the output power of the charging pile electricity consumption units with lower priority levels according to the priority levels of the charging pile electricity consumption units. Referring to fig. 4, fig. 4 is a schematic diagram illustrating an embodiment of instructing a charging post platform to adjust output power of charging post power consumption units according to priorities. Specifically, if 4 charging pile electricity consumption units (charging piles) are included in the target area, the maximum output power of each charging pile electricity consumption unit is 7kW, the reduced electricity consumption capacity threshold is 21kW, and when the total output power of the 4 charging pile electricity consumption units does not exceed 21kW, the priorities of the 4 charging pile electricity consumption units are obtained, for example, it is determined that the priorities of the charging piles 2 and 4 are higher than those of the charging piles 1 and 3 according to the priorities, and the output power of the charging pile electricity consumption unit with the higher priority can be ensured according to the priority of the priorities, for example, the output power of the charging piles 1 and 3 is adjusted to 50% of the maximum output power of 7kW, that is, 3.5kW, and the unit output power of the charging piles 2 and 4 can be kept unchanged at the maximum output power of 7 kW.
For example, when the server analyzes that the target electricity utilization unit with the electricity utilization abnormality is the charging pile electricity utilization unit on the charging pile side, the server may further instruct the charging pile platform to only reduce the output power of the target electricity utilization unit alone.
In one embodiment, after instructing the charging post platform to raise the power usage capacity threshold of the charging post power unit, the method further comprises: and indicating the charging pile platform to increase the output power of all and/or part of the charging pile power consumption units according to the increased power consumption capacity threshold of the charging pile power consumption units.
In this embodiment, after the server of the EMS platform instructs the charging pile platform to increase the power consumption threshold, the server may further instruct the charging pile platform to correspondingly increase the output power of all or part of the charging pile power consumption units according to the increased power consumption threshold of the charging pile power consumption units. The strategy for adjusting the output power of the charging pile power utilization unit can be set according to business requirements, the specific strategy can refer to the strategy for reducing the output power of the charging pile power utilization unit of the embodiment, and the strategy for increasing the output power of the charging pile power utilization unit can be opposite to the strategy for reducing the output power of the charging pile power utilization unit. For example, it may include: the output power of each charging pile electricity utilization unit is uniformly increased, the output power of the charging pile electricity utilization unit with higher priority level is preferentially increased according to the priority level of each charging pile electricity utilization unit, and/or the output power of the target electricity utilization unit is only increased independently.
In one embodiment, a method for determining a power consumption capacity threshold of a power unit of a charging pile comprises the following steps: acquiring a transformer capacity threshold of a target area; predicting building power load of each building power unit at the building side; and calculating the power utilization capacity threshold value which can be distributed to the power utilization units of the charging piles according to the capacity threshold value of the transformer and the building power utilization load.
In this embodiment, when the power capacity threshold of the charging pile is adjusted down or up, the size of the value to be adjusted may be determined according to the above method. According to the embodiment, the power utilization capacity which can be distributed to the power utilization units of the charging piles can be dynamically calculated by predicting or monitoring the building power utilization load of the building power utilization units on the building side in real time and combining the transformer capacity threshold value of the whole target area.
For example, the server may use the following relation according to the sum of the power loads of the building power utilization 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 0.2-0.3 or set according to business requirements, so that the power utilization capacity threshold of the charging pile power utilization units which can be distributed for use at present is determined.
For example, historical electricity load data of each building electricity unit on the building side can be subjected to data precipitation processing in advance, and after the data precipitation time sequence meets a preset period, an electricity load prediction model is established by using a deep learning algorithm and a simulation algorithm, and the building electricity load on the building side in a certain time is predicted by using the electricity load prediction model. The preset period can be set by a user, for example, one day, one month, one year, and the like.
Next, the charging pile power consumption capacity adjusting method according to the present application is further described with reference to an application example, and fig. 5 is a schematic flow chart of the charging pile power consumption capacity adjusting method in the application example. The method specifically comprises the following steps:
step 1, monitoring the current total power load of all power utilization units. Specifically, the server of the EMS platform may obtain the current power loads of the power consumption units monitored by the power distribution system by communicating with the power distribution system, and may calculate the sum of the current power loads of the power consumption units to obtain the current total power loads of all the power consumption units.
Step 2, the server monitors whether abnormal conditions such as sudden power rise of a certain power utilization unit or certain power utilization units occur in real time, if yes, the step 3 is carried out; if not, returning to the step 1.
Step 3, the server compares the current total power load with a preset first early warning value, judges whether the current total power load is greater than the first early warning value, and if yes, enters step 4; if not, go to step 5.
And 4, generating alarm information, and/or starting a backup protection measure, and/or indicating to reduce the power consumption capacity threshold of the power consumption unit of the charging pile. Specifically, when the current total power load is greater than the first warning value, the server can eliminate the power utilization abnormality of the whole target area in time through the measures.
Step 5, the server compares the current total power load with a preset second early warning value, judges whether the current total power load is greater than the second early warning value, and if yes, enters step 6; if not, go to step 8.
And 6, indicating to reduce the power consumption capacity threshold of the power consumption unit of the charging pile. Specifically, the server can generate a power consumption threshold value reduction instruction, and instruct the charging pile platform to reduce the power consumption threshold value of the charging pile power consumption unit.
And 7, indicating to reduce the output power of the charging pile power utilization unit. Specifically, after instructing the charging pile platform to reduce the power consumption threshold of the charging pile power consumption unit, the server can further instruct the charging pile platform to correspondingly reduce the output power of the charging pile power consumption unit according to the reduced power consumption threshold.
And 8, indicating to increase the power utilization capacity threshold of the power utilization unit of the charging pile. Specifically, the server can generate a power consumption threshold value heightening instruction, and instructs the charging pile platform to heighten the power consumption threshold value of the charging pile power consumption unit.
And 9, indicating to increase the output power of the charging pile electricity utilization unit. Specifically, the server can further instruct the charging pile platform to correspondingly increase the output power of the charging pile power consumption unit according to the increased power consumption capacity threshold value after instructing the charging pile platform to increase the power consumption capacity threshold value of the charging pile power consumption unit.
