With the popularization of new energy automobiles, how to effectively supply energy to new energy automobiles with insufficient energy becomes a focus of attention of owners and manufacturers. Among them, building a charging facility (e.g., building a charging pile capable of providing a charging power source for the battery of the electric vehicle) is one of the mainstream solutions for solving the above problems. Taking the charging pile of the electric automobile as an example, the charging pile is widely installed in places with relatively concentrated charging demands, such as parking lots, residential quarters, large shopping malls, service areas and the like, due to the factors of small occupied area, low cost, convenient use and the like. The user is when using charging pile, only need to follow the rifle socket that charges with the rifle of charging and extract and insert the interface that charges on the electric automobile can charge for electric automobile's power battery, only need after charging to insert the rifle that charges once more back in the rifle socket that charges can. However, as the holding capacity of electric vehicles continues to increase, some problems associated with charging facilities also follow.

As the amount of electric vehicles kept increases greatly, the demand for charging facilities also increases greatly, and users prefer to have enough charging facilities in a cell or a parking lot for charging electric vehicles. However, planning, construction and upgrading of the power grid are a long-term process, and the construction of charging facilities of electric vehicles as an emerging thing is not usually in the planning of the existing power grid. If a charging facility is to be built in a centralized large-area manner, it is difficult to find a place capable of providing a corresponding power supply capacity. Even if the charging facility is put into use, the charging facility is limited by the rated power of the power grid. This kind of problem is especially outstanding in the project is add to the electric pile of filling in current parking area and old district: the power consumption capacity of the existing parking lot or the old community is generally planned and cannot be increased in capacity under the general condition, if a large number of charging facilities are additionally arranged regardless of the power consumption capacity, the power grid is likely to be impacted due to simultaneous use of a plurality of charging facilities, so that large-area power failure accidents are caused, the daily life and normal traveling of users are influenced, and the frequent occurrence of the power failure accidents is not beneficial to popularization of electric automobiles.

Detailed Description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

It should be noted that the terms "first" and "second" in the description of the present invention are used for convenience of description only and do not indicate or imply relative importance of the devices, elements or parameters, and therefore should not be construed as limiting the present invention.

On a temporal and spatial scale, the charging demand has a spatial-temporal imbalance. The charging demand is initiated by a user on a charging facility, and is reflected by the overall load demand on the power grid through the power transmission and distribution system to the power supply side. The charging demand itself has an imbalance in space-time, and if the power supply and distribution facilities are designed under the unbalanced input, the demand on the power supply equipment for power transmission and distribution is increased, and the impact on the power grid is increased. But on the other hand, the charging requirement of the user can also be flexibly realized, if the charging requirement can be adjusted in a space-time two-dimension mode through sharing and ordered scheduling, the load is required smoothly, the investment and the transformation cost of power transmission and distribution equipment can be reduced, and the impact of charging on a power grid can also be reduced under the existing condition.

The above needs are directly reflected in the following application scenarios:

(1) public parking area installation fills electric pile scene:

in order to promote the development of new energy automobiles, a lot of local governments stipulate that the proportion of charging piles equipped in parking lots is not less than 10% of the total amount. This policy is often limited in implementation by the parking lot power distribution capacity. For example, charging piles need to be installed in 100 parking spaces of a parking lot, 700kW of power consumption capacity is needed if the rated power of each pile is 7kW, but a power distribution facility of the parking lot can only support 300kW of power distribution capacity, and at this time, the installation of 100 piles needs to be completed by using a capacity sharing and orderly charging method according to the space-time imbalance of the charging demand.

(2) The new user installation of district electric automobile fills electric pile scene:

many electric vehicle users cannot obtain approval due to the limit of the power distribution capacity of the cell when installing the electric vehicle. For example, the cell capacity has a margin of only 140kW, still noted 7kW per stake power rating, and can only be installed for the first 20 users. If at this moment can utilize capacity sharing and orderly charging according to the space-time imbalance of the charging demand, even other electric loads of the community, it is possible to install the charging pile for the user who reports the installation later.

In order to know the electricity utilization condition in the power distribution system in time and realize the capacity sharing, the invention provides a capacity sharing system which comprises the following components: the method comprises the following steps that a corresponding acquisition and measurement terminal is arranged for the power distribution equipment and is used for acquiring and measuring power consumption data of the power distribution equipment; a corresponding collecting and executing terminal is arranged for the charging facility and is used for acquiring the charging request and the working state data of the charging facility; in addition, a server is also provided. Considering that many places where charging piles are installed do not have wired access conditions, wireless communication is generally adopted for terminals (acquisition and testing terminals and acquisition and execution terminals), when the terminals adopt a wireless scheme, if the terminals directly communicate with a server, a 3G/4G network is generally preferred, but the following problems exist when the 3G/4G network is adopted:

(1) the coverage is limited by 3G/4G network signals, especially in remote areas and basements;

(2) communication rate and bandwidth are limited by network characteristics;

(3) when the data volume is large, the communication cost is high.

For the reasons, the intermediate node is arranged for receiving the functions of part of the servers, so that the data uploading speed of the terminal is improved, and the network delay of the charging facility when the charging facility responds to the ordered scheduling command is reduced.

The collecting and testing terminal is divided into a plurality of terminal groups, and each terminal group corresponds to one intermediate node. Each intermediate node and the corresponding terminal group form a cluster, namely a local area network. The local area network is preferably realized in a form of a wireless self-organizing Mesh network, and an intermediate node is used as an access node to access the Ethernet and realize communication with a cloud server. The intermediate node can be laid in a place covered by a wireless network or provided with a wired access condition so as to realize communication interconnection with the cloud server. The role of the intermediate node is illustrated below with a specific example:

if a terminal-server direct connection scheme is adopted, the performance of a 3G/4G network in a terminal laying area needs to reach the index, and the challenge is great in some areas. If the intermediate node scheme is adopted and a wireless local area network such as Zigbee is laid between the intermediate node and the terminal equipment, the network performance index can be achieved within the protocol allowable range.

In view of the above-mentioned problems, the present invention provides an embodiment of a power distribution system, where the power distribution system of this embodiment includes at least one stage of power distribution equipment, and further includes a capacity sharing system, where the power distribution equipment can be connected to a plurality of charging facilities, and a sum of rated powers of the plurality of charging facilities is greater than a power available to the charging facilities from the power distribution equipment.

Fig. 1 is a schematic diagram of the configuration of an embodiment of a power distribution system of the present invention. As shown in fig. 1, the power distribution system of the present embodiment includes two levels of power distribution devices, wherein the first level of power distribution device is a transformer, and the second level of power distribution device is a distribution box. The lowermost box in the figure is the original one, behind which "other loads" such as lighting, heating, cooling, motors, etc. are connected. The rest distribution boxes are newly added, and a charging facility (a direct current charging pile and an alternating current charging pile are connected behind the newly added distribution boxes. Given that the sum of the rated power of the charging facilities in the distribution system is greater than the power available to the transformers for these charging facilities, capacity sharing is required based on the charging demand, the space-time imbalance of other loads.

With continued reference to fig. 1, an embodiment of the capacity sharing system of the present invention comprises: at least one terminal group (at least one sampling terminal 10 and at least one sampling terminal 20 are included in the terminal group), intermediate nodes 30 for capacity sharing in one-to-one correspondence with the terminal group, and a server 40.

In this embodiment, one acquisition and measurement terminal 10 is installed for all power distribution devices (transformers and distribution boxes) in the power distribution system, one acquisition and measurement terminal 20 is installed for all charging facilities, the acquisition and measurement terminals 10 and the acquisition and measurement terminals 20 are classified into the same terminal group, the terminal group communicates with corresponding intermediate nodes 30, and a server 40 is further arranged on a cloud platform. The intermediate node 30 is used for receiving and analyzing the electricity utilization data and making decisions; the server 40 is used to manage data and interact with third party platforms, and the server 40 can also communicate with the mobile terminal to guide the client to avoid peak periods of electricity usage or avoid certain areas with insufficient remaining power. The server 40 performs big data statistics according to the charging service data, can grasp in a certain specific area which time periods have the highest utilization rate of the charging facilities and which time periods have more idle charging facilities, and guides the client to avoid the peak period as much as possible; or, in the same time period, the utilization rate of the charging facilities in certain areas is higher, and the idle charging facilities in certain areas are more (namely, surplus power is available), so that the customer can be guided to the areas with relatively surplus power to charge.

Here, the "sampling and testing terminal" and the "sampling and execution terminal" are explained:

the measurement of the finger-shaped state quantity can measure branch current (effective value), branch voltage (effective value), active power, reactive power (or phase angle, power factor), accumulated electric quantity and the like; "mining" refers to data collection, and objects mainly include two types: the system comprises an electric measuring module or an electric meter, and a data interface of charging facilities (a charging pile, a charging station, a battery replacement station and the like); the 'execution' refers to the execution of a command, receives a control instruction issued by the intermediate node, confirms that an instruction control object is correct, and forwards the instruction to a downstream charging facility.

In order to clearly show the transfer relationship between data and power between different devices, we simplify fig. 1 to fig. 2. As shown in fig. 2, the power distribution system of the present embodiment includes: the capacity sharing system (composed of the acquisition and testing terminal 10, the acquisition and execution terminal 20, the intermediate node 30 and the server 40), the transformer 100 and the distribution box 200. The load of the power distribution system comprises: charging facility 300, other loads 400.

Wherein, the sampling and testing terminal 10 is configured as: collecting power consumption data on corresponding power distribution equipment, and uploading the power consumption data to an intermediate node 30 corresponding to a terminal group where the collecting and testing terminal is located; the adoption terminal 20 is configured to: acquiring a charging request corresponding to the charging facility 300, and uploading the charging request to an intermediate node 30 corresponding to a terminal group where the collecting and executing terminal is located; the intermediate node 30 is configured to: receiving power consumption data uploaded by the acquisition and test terminal 10 and a charging request uploaded by the acquisition and execution terminal 20 in the corresponding terminal group, and sending a charging instruction to the acquisition and execution terminal 20 corresponding to the charging request according to the power consumption data; charging service data are also uploaded to the server 40, and a charging strategy is obtained through the server 40; the server 40 is configured to: and receiving the charging service data uploaded by the intermediate node 30, and sending a charging strategy to the intermediate node 30. The charging instruction comprises whether charging is allowed or not and available power information under the condition that charging is allowed; the charging service data at least comprises: the charging request information received in the terminal group corresponding to the intermediate node 30, and the available power allocated accordingly. In addition, the charging service data may further include: the intermediate node corresponds to the type and ID of the acquisition and measurement terminal in the terminal group, the type and ID of the acquisition and measurement terminal, the electric quantity and state (normal operation or fault) of each branch, actual charging current, available capacity and the like. The server 40 can determine the operation status of the power distribution system according to the charging service data, for example, whether the power distribution system is working normally, whether each branch has remaining capacity, how many charging facilities are charging, and the charging current. The server can also display the current operating condition of the power distribution system through a human-computer interaction interface and receive a charging strategy set by an operation manager. The server may also interact with the user terminal, e.g. displaying charging information, accepting a subscription request, etc.

The charging facility 300 mentioned in the embodiment of the present invention includes: direct current charging pile and/or alternating current charging pile. The server 40 is disposed in the cloud, and the server 40 and the intermediate node 30 communicate with each other through a wired network or a wireless network. The intermediate node 30 communicates with the sampling terminal 10 and the sampling terminal 20 in the corresponding terminal group via a wired network, a wireless network, or a power carrier. The wireless network includes: 3G/4G, WIFI, Bluetooth, Zigbee, or NBIoT. The adoption terminal and the corresponding charging facility communicate with each other through one of WIFI, Bluetooth, Zigbee, NBIoT, power carrier waves or field buses.

It should be noted that: in practice there may be more levels of distribution equipment. In this embodiment, the power distribution devices and the sampling and testing terminals, and the charging facilities and the sampling and testing terminals are all in a one-to-one relationship, and in practical application, the relationship may also be a many-to-one relationship, that is, a plurality of power distribution devices configure the same sampling and testing terminal, and a plurality of charging facilities configure the same sampling and testing terminal.

In fig. 2, the sampling terminals and the sampling terminals in the same transformer power supply area are allocated to the same terminal group. Fig. 3 is a schematic diagram of an alternative terminal grouping method of the capacity sharing system of the present invention. As shown in fig. 3, the

sampling terminals

10 and 20 in the same transformer 100 power supply area are allocated to different terminal groups. In actual use, the sampling and testing terminals and the sampling and executing terminals in different transformer power supply areas can be distributed to the same terminal group, as long as the actual transmission conditions meet the required timeliness.

To describe the capacity sharing system of the present invention in more detail, the intermediate node and the acquiring terminal in the capacity sharing system will be described below with reference to fig. 4 to 12, respectively.

Fig. 4 is a schematic configuration diagram of a first embodiment of an intermediate node for capacity sharing according to the present invention. As shown in fig. 4, the intermediate node 30 of the present embodiment includes: the system comprises an electricity consumption data receiving module 31, a charging request receiving module 32, a charging control module 33 and a service data uploading module 34.

Wherein, the power consumption data receiving module 31 is configured to: receiving power consumption data of the power distribution equipment uploaded by each acquisition and test terminal in the corresponding terminal group; the charging request receiving module 32 is configured to: receiving one or more charging requests from each executing terminal in the corresponding terminal group; the charging request is a charging request of a corresponding charging facility acquired by the collecting and executing terminal; the charging control module 33 is configured to: generating a charging instruction according to the electricity utilization data, and sending the charging instruction to the execution terminal corresponding to each charging request; the service data upload module 34 is configured to: and uploading the charging service data to the server.

The terminal group here includes: the system comprises at least one collecting and testing terminal and at least one collecting and executing terminal; the charging instructions include whether charging is allowed and available power information if charging is allowed.

Specifically, the charging control module 33 may include: a data updating unit 331, an instruction generating unit 332, and an instruction transmitting unit 333.

Wherein, the data updating unit 331 is configured to: updating the capacity allocation data according to the power utilization data; the instruction generation unit 332 is configured to: after receiving a charging request, inquiring capacity distribution data, and generating a charging instruction according to an inquiry result; the instruction transmitting unit 333 is configured to: and sending the charging instruction to a collection and execution terminal corresponding to the charging request.

In this embodiment, the electricity consumption data may include: and acquiring and measuring the actual total power used by the power distribution equipment corresponding to the terminal.

Accordingly, the data updating unit 331 may be specifically configured to: calculating first residual power of the power distribution equipment according to the total rated power and the actual total power of the power distribution equipment corresponding to the acquisition and measurement terminal, and updating capacity distribution data; wherein the capacity allocation data comprises at least: a first remaining power of each power distribution device in the power distribution system.

The instruction generating unit 332 may include: a selecting subunit 3321, a charging policy obtaining subunit 3322, and a power allocating subunit 3323.

The selecting subunit 3321 is configured to: and inquiring the first residual power of each level of power distribution equipment at the front end of the electric branch where the charging facility corresponding to the charging request is located according to the capacity distribution data, and taking the minimum value of the first residual power.

Because we have added new distribution equipment to the distribution system of fig. 1, the sum of the power ratings of all the distribution boxes in fig. 1 may exceed the power rating of the transformer, not only should we consider that distribution equipment connected to the charging facility cannot be overloaded, but also should consider that the previous transformer cannot be overloaded. In practical applications, there may be multiple levels of distribution equipment in the distribution system, and it is necessary to ensure that the load on each level of distribution equipment on the electrical branch from the distribution equipment connected to the charging facility to the transformer cannot exceed the rated capacity of the distribution equipment. Therefore, it is necessary to calculate the remaining power of these power distribution devices and take the minimum value thereof for power distribution in the subsequent step.

The charging policy acquisition subunit 3322 is configured to: and acquiring a preset charging strategy in the intermediate node, or acquiring the charging strategy through a server.

Power distribution subunit 3323 is configured to: distributing available power for the charging facility corresponding to the charging request according to the obtained charging strategy, and further generating a charging instruction; wherein the allocated available power is less than or equal to the minimum value of the first remaining power.

In this embodiment, the charging policy includes: when the minimum value of the first residual power is greater than or equal to the preset minimum charging power and is less than the rated power of the charging facility, allowing charging, and taking the minimum value of the first residual power as the available power of the charging facility; when the minimum value of the first residual power is larger than the rated power, allowing charging, and taking the rated power as the available power of the charging facility; and when the minimum value of the first residual power is smaller than the preset minimum charging power value, rejecting the charging or reducing the available power of one or more charging facilities in the charging state, so as to distribute the available power for the charging facility corresponding to the charging request.

Here, "reduce the available power of one or more charging facilities in a charging state so as to allocate the available power to the charging facility corresponding to the charging request" may employ the following method:

finding the power distribution equipment corresponding to the minimum value of the first residual power, and reducing the power of the charging facility directly or indirectly connected with the rear end of the power distribution equipment according to the user priority or the charging time length, namely: and reducing the charging power of the charging facility corresponding to the user with lower priority according to a certain proportion, or reducing the charging power of the charging facility with later charging starting time according to a certain proportion. By the method, the minimum value of the first residual power is larger than or equal to the preset minimum charging power, so that the available power is distributed to the charging facility corresponding to the current charging request. If the requirement cannot be met after the adjustment according to the method calculated in advance, the current charging request is directly rejected without adjustment.

In this embodiment, if the minimum value of the first remaining power is greater than the preset minimum charging power, a maximum allocation policy is adopted, and a random allocation policy may also be adopted in practical application: selecting a random number between a preset minimum charging power and a minimum value of the first residual power, and if the random number is greater than or equal to the rated power of the charging facility, taking the rated power of the charging facility as available power, otherwise, taking the random number as available power.

If the intermediate node receives charging requests sent by a plurality of execution terminals within a set time period, the available power can be distributed to the charging facilities corresponding to the charging requests according to an average distribution strategy: dividing the residual capacity of the power distribution system (namely the first residual power of the transformer) by the number of the current charging requests according to the capacity distribution data to obtain an average value; for each charging facility which initiates a charging request at present, selecting a minimum value from the average value and first residual powers of all levels of front-end distribution equipment corresponding to the charging facility; if the minimum value is greater than or equal to the rated power of the charging facility, allowing the charging facility to be charged and taking the rated power of the charging facility as available power; and if the minimum value is smaller than the rated power of the charging facility and is larger than or equal to the preset minimum charging power, allowing the charging facility to be charged and taking the minimum value as the available power. And if the minimum value is less than the preset minimum charging power, the charging facility is not allowed to be charged.

Fig. 5 is a schematic configuration diagram of a second embodiment of an intermediate node for capacity sharing according to the present invention. As shown in fig. 5, the intermediate node 50 of the present embodiment includes: the charging system comprises a power consumption data receiving module 51, a charging request receiving module 52, a charging control module 53, a service data uploading module 54 and a charging state receiving module 55.

The configurations of the electricity consumption data receiving module 51, the charging request receiving module 52, and the service data uploading module 54 are respectively the same as the corresponding modules in the first intermediate node embodiment.

The charge status receiving module 55 is configured to: and receiving the charging facility working state data uploaded by each acquisition and execution terminal in the corresponding terminal group. The charging facility operating state data includes: and acquiring the current charging power, the charged time and the like of the charging facility corresponding to the terminal.

The charging control module 53 includes: data updating unit 531, instruction generating unit 532, instruction transmitting unit 533, and verifying unit 534. The configurations of the data updating unit 531, the instruction generating unit 532, and the instruction sending unit 533 are the same as the configurations of the corresponding units in the first intermediate node embodiment; the verification unit 534 is configured to: calculating second residual power of each level of distribution equipment according to the working state data of the charging facility and the total rated power of each level of distribution equipment at the front end of the electrical branch where the corresponding charging facility is located; verifying whether the corresponding first remaining power is correct based on the second remaining power.

Because the first residual power is calculated by collecting the data of the power distribution equipment through the collection and measurement terminal, not only the rear-stage charging facility but also other loads and rear-stage line loss are considered, and the second residual power only considers the rear-stage charging facility, the first residual power of the same power distribution equipment is necessarily smaller than the second residual power under normal conditions, if the first residual power of certain power distribution equipment is found to be larger than the second residual power through the verification result, the corresponding collection and measurement terminal or the collection and measurement terminal possibly has a problem and needs to be overhauled immediately.

In this embodiment, the charging policy includes: when the minimum value of the first residual power is greater than or equal to the preset minimum charging power and is less than the rated power of the charging facility, allowing charging, and taking the minimum value of the first residual power as the available power of the charging facility; when the minimum value of the first residual power is larger than the rated power, allowing charging, and taking the rated power as the available power of the charging facility; and when the minimum value of the first residual power is smaller than the preset minimum charging power value, rejecting charging, or adjusting the available power of each charging facility in the charging state according to the charging facility working state data, so as to distribute the available power for the charging facility corresponding to the charging request.

It can be seen that, different from the charging strategy in the first intermediate node embodiment, in the charging strategy of this embodiment, when the minimum value of the first remaining power is found to be smaller than the preset minimum charging power value, in this embodiment, "the available power of each charging facility in the charging state may be adjusted according to the charging facility operating state data", specifically: and selecting the charging facility with smaller charging power according to the current charging power of the charging facility to reduce the power by a certain proportion. Since the charging facility, which is less powerful to charge, is already completing its current charging task quickly, reducing its available power appropriately does not have a large impact on it. If it is calculated in advance that the minimum value of the first remaining power adjusted by the method is still smaller than the preset minimum charging power value, the charging request is directly rejected without adjustment. Of course, we can also use the charging strategy in the first embodiment of the intermediate node to adjust.

In the case that all loads in the power distribution system are charging facilities, or in the case that access terminals of other loads in the power distribution system are additionally provided with adoption terminals, the intermediate node for capacity sharing may also adopt the following third embodiment or fourth embodiment.

Fig. 6 is a schematic configuration diagram of a third embodiment of an intermediate node for capacity sharing according to the present invention. As shown in fig. 6, the intermediate node 60 of the present embodiment includes: the charging system comprises a charging state receiving module 61, a charging request receiving module 62, a charging control module 63 and a service data uploading module 64.
