It should be noted that the present application also provides an alternative implementation, and the details of the implementation are described below.

In the present embodiment, the charging load of a single household vehicle is a small load with respect to the distribution capacity of the distribution area, continuous power adjustment of the charging load of a single vehicle is not necessary, and the adjustment of the charging start timing of a plurality of vehicles makes it possible to achieve the object of orderly charging management.

In the ordered charging, charging load time period sequences of a plurality of automobiles are adjusted in an expected time period for a plurality of automobiles which are connected to the same distribution network and are ready to be charged, and an expected load curve is combined to achieve the aim of ordered charging management.

And (3) network load coordination management of ordered charging: and establishing an electric vehicle ordered charging operation management platform, and designing an ordered charging strategy according to the predicted power grid load curve, the predicted clean energy load curve, the electric vehicle charging demand and the local capacity limit of the power distribution network. Monitoring the main network, the distribution network and the clean energy load in real time, deciding the charging time sequence to be executed by the electric automobile charged in the current network, and issuing instructions to the corresponding charging equipment to complete ordered charging management.

If the capacity limit of the local distribution network exists and the requirement that all vehicles are charged in the respective specified time period cannot be met, an interruptible load electricity price mechanism needs to be introduced, the electricity supply of the interruptible load electricity price mechanism is reduced or interrupted, or the charging requirement is adjusted to other time periods to be completed.

The main principle of realizing ordered charging is as follows:

the principle that the sequential charging of the electric automobile should be kept on safe and reliable priority is achieved, excellent user and power grid interaction experience is provided, the sharing of charging resources is achieved, and the utilization rate of charging facilities is improved.

Safety: information security is ensured, and hacker attack is prevented; the device is safe and has strong capability of preventing external force damage; the safety of the charging process of the electric automobile is ensured.

Reliable: through multiple communication modes, high communication reliability is realized, reliable control is guaranteed, the success rate of control instructions is high, and the user operation response is quick. Provide a floor-in-place operation that can meet basic charging requirements even if communication is lost altogether.

Ordered charging demand analysis and strategy design:

the method is characterized in that a private passenger car is used as a main user scene, a control strategy for ordered charging is designed according to the car using requirements of users, the user is mainly divided into a time priority type user and a cost priority type user except an immediate charging management strategy, and two ordered charging modes of 'as fast as possible' and 'low-cost charging' are provided for the user. The specific introduction is as follows:

the term "charge as fast as possible" means that the user needs to complete the electric energy supply as soon as possible, and is not sensitive to the charge price. If the charging capacity of the current power grid is allowed and the charging requirement of a user can be met, immediately entering a charging state; otherwise, the vehicle enters a waiting state, and when the charging capacity of the power grid is recovered, the vehicle immediately enters a charging state.

The term "low-cost charging" means that the user is not sensitive to the charging start timing and wants to achieve the charging target at the lowest possible charging cost within the set vehicle-lifting time. The mode has certain flexibility in specific charging time, can flexibly control the charging power of the vehicle, and requires a user to clearly determine the parking charging time.

1. An orderly charging control mode:

(1) the control principle is as follows:

according to the prior art mode, the control mode of ordered charging can be divided into two categories, one is circuit breaking type control, which means that the on-off control of a power supply loop is realized through an ammeter or related equipment, so that the charging load is cut and continued. The segmented control is only suitable for charging piles without regulation capacity, and emergency protection measures when the charging piles have power supply capacity exceeding limit, or the situation that a user agrees to participate in ordered charging management in a segmented mode; the other is load adjustment type control, which means that the charging load control can be continuously realized through the power adjustment of the charging equipment (comprising a charging pile standby mode supporting the charging with PWM less than 5 percent of pause)

(2) Controlling a superposition mode:

the circuit segment type control adjusts the load restarting time by segmenting the charging load, realizes power control in different time periods, and realizes whole load regulation and control by a load stacking mode.

The load adjustment type control ensures that the charging process is basically continuous by adjusting the load size, and dynamically adjusts the ordered charging power by continuously adjusting the charging power.

2. Application scenario for ordered charging:

the application scenario of the orderly charging for the residential area can be described as follows:

1. after a user vehicle drives into a parking space and finishes the connection of a charging cable, the user can set charging requirements such as charging quantity and vehicle lifting time according to the requirements through a mobile phone APP or a human-computer operation interface of the ordered charging controller, and makes charging mode selection from two charging modes of 'charging as fast as possible' and 'charging at low cost', and submits a charging request.

2. And the ordered charging control center performs pre-scheduling arrangement of a charging plan according to the charging request submitted by the user, and checks the reasonability and effectiveness of the charging request. If the request is reasonable and can be completed, generating an order; otherwise, the order is not generated, the user is informed of the reason, and a suggestion is given.

3. For a vehicle that selects the "as fast as possible" mode, it will immediately enter a state of charge under grid charge capacity licensing conditions; otherwise, the vehicle enters a waiting state. And once the grid charging condition is met, the charging state is immediately entered.

For the vehicle selecting the low-cost charging mode, the vehicle waits for a low-price period to enter a charging state according to the scheduled charging plan; if the charging electric quantity can not meet the charging requirement in the valley period, a charging plan is arranged for the charging electric quantity in other periods so as to meet the charging target electric quantity.

4. In the charging process, a user can inquire information such as charging power, charged amount, whether a target can be achieved or not in real time through the mobile phone APP or the ordered charging controller.

5. The ordered charging control center can analyze the deviation situation of the order target achievement of the user in real time. If the expected deviation is found to be larger, the user is informed in time so that the user can adjust the charging plan according to the arrangement of the user vehicle.

6. When the charging target is achieved, the charging process is automatically stopped. Meanwhile, the user will receive the completion information of the charging order.

The application scenario of the orderly charging for the unit park is different from the above. If the unit is responsible for paying the electricity charge, the owner does not need to make the mode selection of charging as soon as possible and charging as low as possible. If the owner pays the electric charge, the mode of charging as fast as possible is reserved, and if the charging electric charge has a time-of-use electricity price mechanism, the mode of charging with low charge is provided at the same time.

3. Strategy design principle of ordered charging:

the ordered charging strategy design fully meets the charging requirements of users, and strategy distribution is carried out according to an ordered charging control mode and an application scene in accordance with the principle of 'first come first get and minimum default' on the premise of fairness and justice.

(a) Minimum rule of default: after a successful acceptance and conversion of a charging application to an order, efforts should be made to achieve its charging goals, unless there are irresistible reasons. No matter what type of charging application, the application will not be accepted if it will affect the charging requirements of the existing order being met. In the charging process, if the order is predicted to be unable to perform, the charging plan can be adjusted under the condition of not influencing the charging targets of other orders, the charging plan which possibly violates the order is preferentially arranged, and the order violation is avoided as much as possible. If the violation is unavoidable, the stress claim violation singularity and the amount of violation power is minimal. The ordered charging of the unit garden needs to consider the capacity management or demand management requirement of the unit load, and avoids the corresponding economic loss caused by the fact that the unit violates the related power utilization convention.

(b) Order timing priority principle: the new charging order should not affect the existing order unless the principle is irresistible. When the charging targets are equally satisfied, the charging plan is prioritized in order of order generation time. When the charging load needs to be reduced due to insufficient charging capacity, the order in the order generation time sequence is preferentially adjusted.

(c) The principle of continuous smoothing of the charging process is as follows: when the charging plan is arranged, the charging process of the single load is ensured to be continuous as much as possible, and the whole load is ensured to be smooth as much as possible.

(d) Principle of performing as early as possible: during the charging planning, the charging process should be started as early as possible under the conditions of meeting the performance goal, maximizing the benefit of the user and continuously and smoothly as possible, so as to reduce the default risk that the charging electric quantity cannot be completed in the appointed lift time.

(e) The principle of maximum utilization: on the premise of not influencing the charging target and benefiting of the existing order, the charging start-stop time and the charging power can be optimally adjusted according to the charging requirement characteristics of different modes, so that the charging capacity of the power grid is fully utilized, and the charging service requirements of more vehicles are met. In order to fully utilize the load time translation characteristic of the 'low cost charging' vehicle, the earliest lifting time can be properly limited.
