The rapid expansion of the EV market poses significant challenges to the safe and stable operation of existing power systems, especially during peak load periods. Large-scale EV charging can lead to a surge in grid load, threatening grid stability. Scheduled charging technology and Vehicle-to-Grid (V2G) technology are considered effective means to address this challenge. By scheduling the charging and discharging processes of EVs, the load pressure on the grid during peak hours can be alleviated, the grid's capacity to absorb renewable energy can be improved, ancillary services and peak-shaving capabilities can be provided, and the grid's flexibility and reliability can be enhanced.

To address the problems mentioned in the background art, this application provides a real-time control method for the charging and discharging power of electric vehicles. In this method, access information of at least one target charging pile is acquired, and a set of electric vehicle charging and discharging events and a target aggregate power guidance curve are established based on the access information. Based on the access information and the target aggregate power guidance curve, an aggregate power decomposition operation is performed to obtain the reference power for each electric vehicle charging and discharging event in the electric vehicle charging and discharging event set.

This application enables real-time control of the charging and discharging power of electric vehicles (EVs) based on EV access information collected from charging piles, given a lumped power curve to be tracked. It is easy to implement, has low computational complexity, and is suitable for real-time control of EV charging and discharging power in scenarios with large-scale EV access. This solves the problems of high computational complexity and inability to perform real-time control of charging and discharging power for large-scale EVs in existing large-scale EV charging services.

[0033] Specifically, Figure 1 This is a flowchart illustrating a real-time control method for the charging and discharging power of an electric vehicle, as provided in an embodiment of this application.

[0034] like Figure 1 As shown, the real-time control method for the charging and discharging power of this electric vehicle includes the following steps:

[0035] In step S101, access information of at least one target charging pile is obtained, and a set of electric vehicle charging and discharging events and a target set total power guidance curve are established based on the access information at the current moment.

[0036] The embodiments of this application can first set the access information of multiple charging piles. For example, the embodiments of this application can set time 0 as the current time and set the number of simulation time periods to N. t Furthermore, embodiments of this application can establish a set of electric vehicle charging and discharging events accessed at a previous time based on the access information. And generate the lumped power guidance curve (i.e., the target lumped power guidance curve) P that needs to be tracked. * The data for the j-th charge / discharge event includes the current battery level. Expected battery level upon departure Expected departure time Maximum charging power and maximum discharge power

[0037] Therefore, the embodiments of this application determine the access information of the charging pile and establish the set of electric vehicle charging and discharging events at the current moment and the lumped power guidance curve that needs to be tracked, thereby providing reliable data guidance and basis for the calculation of parameters such as the reference power of each subsequent electric vehicle charging and discharging event.

[0038] In step S102, based on the access information and the target aggregate power guidance curve, an aggregate power decomposition operation is performed to obtain the reference power of each electric vehicle charging and discharging event in the electric vehicle charging and discharging event set, and to calculate the remaining time and relaxation of each electric vehicle charging and discharging event at the current moment, so as to construct the non-emergency charging and discharging event set and the emergency charging and discharging event set at the current moment through the remaining time and relaxation.

[0039] After establishing the set of electric vehicle charging and discharging events and the lumped power guidance curve to be tracked at the current moment, the embodiments of this application can further perform lumped power decomposition within the simulation period to obtain the reference power for each electric vehicle charging and discharging event. And calculate the remaining time λ for each electric vehicle charging / discharging event at the current moment. j and relaxation θ j For the j-th electric vehicle charging / discharging event, its remaining time relaxation Subsequently, embodiments of this application can construct a set of non-urgent charge / discharge events at the current moment based on the remaining time and relaxation. and a collection of emergency charging and discharging events This effectively ensures the realization of functions such as real-time control of electric vehicle charging and discharging power.

[0040] Optionally, in one embodiment of this application, based on access information and a target aggregate power guidance curve, an aggregate power decomposition operation is performed to obtain the reference power of each electric vehicle charging and discharging event in the electric vehicle charging and discharging event set. This includes: determining the initialization simulation time and initial power information of the target electric vehicle based on access information, and constructing an auxiliary charging and discharging event set through the initialization simulation time; calculating the charging and discharging power corresponding to each auxiliary charging and discharging event in the auxiliary charging and discharging event set according to the initial power information, the target aggregate power guidance curve, and a preset priority criterion; and correcting the starting power of each auxiliary charging and discharging event at the next moment through the charging and discharging power corresponding to each auxiliary charging and discharging event, so as to calculate the reference power of each electric vehicle charging and discharging event based on the corrected starting power.

[0041] It should be noted that, as Figure 2 As shown in the figure, the specific steps for obtaining the reference power for each electric vehicle charging and discharging event in this embodiment of the application are as follows:

[0042] Step 1: Initialize the simulation time (i.e., initialize the simulation time t=0) and initialize the charge of individual charging and discharging events in the simulation (i.e., initialize the charge information).

[0043] Step 2: Filter the set of charging and discharging events that have not yet left before simulation time t (i.e., the set of auxiliary charging and discharging events). That is, for For any charging / discharging event j, its expected departure time is greater than the current simulation time.

[0044] Step 3: For the lumped guidance power to be decomposed The minimum laxity and longer remaining processing time (LLLP) priority criterion is used to prioritize the set of charging and discharging events. The charge / discharge power p of each individual charge / discharge event (i.e., each auxiliary charge / discharge event in the set of auxiliary charge / discharge events) j,t Perform calculations;

[0045] Step 4: Record the charge / discharge power p of each individual charge / discharge event. j And correct the starting charge level at the next moment of the individual charge / discharge event:

[0046]

[0047] Step 5, Simulation time t = t + 1, if t <N t Otherwise, return to step 2;

[0048] Step 6: Calculate the baseline power for each electric vehicle charge / discharge event. The mathematical expression for the reference power is as follows:

[0049]

[0050] Therefore, the embodiments of this application further improve the data basis for real-time control of the charging and discharging power of large-scale electric vehicles by calculating the reference power of each electric vehicle charging and discharging event.

[0051] Optionally, in one embodiment of this application, calculating the charging and discharging power corresponding to each auxiliary charging and discharging event in the auxiliary charging and discharging event set based on initial power information, a target aggregate power guidance curve, and a preset priority criterion includes: calculating the auxiliary remaining time and auxiliary slack corresponding to each auxiliary charging and discharging event, and constructing an auxiliary non-emergency charging and discharging event set and an auxiliary emergency charging and discharging event set based on the auxiliary remaining time and auxiliary slack; performing a charging operation on each auxiliary emergency charging and discharging event in the auxiliary emergency charging and discharging event set at a preset maximum charging power, and correcting the aggregate guidance power based on the target aggregate power guidance curve, and performing load state analysis on the corrected aggregate guidance power. The system makes a judgment; if the corrected lumped guidance power is in a charging load state, then all auxiliary non-emergency charging and discharging events in the set of auxiliary non-emergency charging and discharging events are sorted in ascending order according to the auxiliary remaining time, auxiliary slack, and priority criteria, and the corresponding charging power is allocated to each auxiliary non-emergency charging and discharging event based on the preset charging priority strategy; if the corrected lumped guidance power is in a discharging load state, then all auxiliary non-emergency charging and discharging events in the set of auxiliary non-emergency charging and discharging events are sorted in descending order according to the auxiliary remaining time, auxiliary slack, and priority criteria, and the corresponding discharging power is allocated to each auxiliary non-emergency charging and discharging event based on the preset discharging priority strategy.

[0052] In actual implementation, the embodiments of this application address the lumped guidance power to be decomposed. The specific process of calculating the charge and discharge power of each auxiliary charge and discharge event in the auxiliary charge and discharge event set using the LLLP priority criterion is as follows:

[0053] 1. Calculate the remaining time (i.e., auxiliary remaining time) λ for each auxiliary charge / discharge event. j and relaxation (i.e., auxiliary relaxation) θ j For each auxiliary charge / discharge event j, its remaining time relaxation

[0054] 2. Statistically analyze the set of non-urgent charging and discharging events (i.e., the set of auxiliary non-urgent charging and discharging events). And the set of emergency charging and discharging events (i.e., the set of auxiliary emergency charging and discharging events).

[0055] 3. For each auxiliary emergency charge / discharge event in the auxiliary emergency charge / discharge event set, charging is performed at the maximum charging power, i.e. And correct the lumped guidance power

[0056] 4. Determine the load status of the corrected lumped power guidance. If the corrected lumped power guidance is in a charging load state (i.e., ...) This will aggregate non-urgent charging and discharging events. according to The order is from smallest to largest, meaning that for non-urgent charging and discharging events, the relaxation θ j,t The smaller the value, the higher the charging priority. If the relaxation of non-urgent charging and discharging events is the same, then the remaining time λ... j,t The larger the value, the higher the charging priority; if the corrected lumped guidance power is in discharge load state (i.e. This will aggregate non-urgent charging and discharging events. according to The order is from largest to smallest, meaning that for non-urgent charge / discharge events, the relaxation θ is... j,t The larger the value, the higher the discharge priority. For non-urgent charge / discharge events, the relaxation θ... j,t If they are the same, then the remaining time λ j,t The smaller the value, the higher the discharge priority;

[0057] 5. If the corrected lumped power guidance is in charging load condition (i.e.) Then, charging power can be allocated to individual charging and discharging events (i.e., each auxiliary non-emergency charging and discharging event) one by one according to the charging priority order from high to low, and the lumped guidance power can be adjusted one by one; if the adjusted lumped guidance power is the discharge load (i.e. The charging power is allocated to each individual charging / discharging event (i.e., each auxiliary non-emergency charging / discharging event) in descending order of discharge priority, and the lumped guidance power is adjusted accordingly. The calculation expression for the charging / discharging power corresponding to each auxiliary non-emergency charging / discharging event is as follows:

[0058]

[0059] The lumped guidance power process is corrected as follows:

[0060]

[0061] Therefore, embodiments of this application can obtain a reliable reference power in the look-out phase by calculating the charging and discharging power corresponding to each auxiliary non-emergency charging and discharging event, such as... Figure 2 As shown, this provides guidance and basis for the allocation of reference power in the subsequent redistribution process.

[0062] In step S103, the lumped differential power and charge / discharge power margin at the current moment are calculated based on the set of non-emergency charge / discharge events, access information, and reference power. Based on the lumped differential power, charge / discharge power margin, and reference power, the charge / discharge power corresponding to each electric vehicle charge / discharge event is obtained. This allows the target charging piles corresponding to each non-emergency charge / discharge event and each emergency charge / discharge event in the emergency charge / discharge event set to charge the target electric vehicle using the charge / discharge power and the preset maximum charging power, respectively.

[0063] Furthermore, embodiments of this application can also calculate the lumped differential power and charge / discharge power margin at the current moment through the set of non-emergency charge / discharge events, the access information of the charging pile, and the reference power, and combine the aforementioned reference power to obtain the charge / discharge power of each non-emergency charge / discharge event, so as to control the charging pile corresponding to each non-emergency charge / discharge event to charge the electric vehicle with the charge / discharge power, and control the charging pile corresponding to each charge / discharge event to charge the electric vehicle with the maximum charging power.

[0064] Therefore, the embodiments of this application can, in real time, control the charging and discharging power of electric vehicles based on the electric vehicle access information statistically collected by charging piles, given the lumped power curve that needs to be tracked.

[0065] Optionally, in one embodiment of this application, calculating the lumped differential power and charge / discharge power margin at the current moment based on the set of non-emergency charge / discharge events, access information, and reference power includes: constructing the set of non-emergency charge / discharge events and the set of emergency charge / discharge events at the current moment based on the remaining time and relaxation; and calculating the lumped differential power and charge / discharge power margin based on the reference power, the set of non-emergency charge / discharge events, and the set of emergency charge / discharge events.

[0066] It should be noted that, in the embodiments of this application, the set of non-urgent charging / discharging events and the set of emergency charging / discharging events at the current moment are constructed using the remaining time and relaxation, and the lumped differential power ΔP after the current moment's reference power allocation is calculated using the following formula:

[0067]

[0068] Furthermore, embodiments of this application calculate the set of non-urgent charging and discharging events at the current moment. The charge / discharge power margin δp for non-emergency charge / discharge events j :

[0069]

[0070] Therefore, the embodiments of this application provide reliable data support for calculating the charging and discharging power corresponding to each electric vehicle charging and discharging event by calculating the lumped differential power and the charging and discharging power margin.

[0071] Optionally, in one embodiment of this application, the mathematical expression for the charging and discharging power corresponding to each electric vehicle charging and discharging event in the electric vehicle charging and discharging event set at the current moment is:

[0073] in, This represents the set of emergency charging and discharging events at the current moment. This represents the set of non-urgent charging and discharging events at the current moment. Indicates the maximum charging power; Indicates reference power; δp j ΔP represents the charge / discharge power margin; ΔP represents the lumped differential power; j represents the j-th electric vehicle charge / discharge event in the set of electric vehicle charge / discharge events at the current moment.

[0074] Furthermore, embodiments of this application can calculate the charging and discharging power p corresponding to each electric vehicle charging and discharging event (including emergency charging and discharging events and non-emergency charging and discharging events) in the electric vehicle charging and discharging event set at the current time using the following formula. j :

[0075]

[0076] in, This represents the set of emergency charging and discharging events at the current moment. This represents the set of non-urgent charging and discharging events at the current moment. Indicates the maximum charging power; Indicates reference power; δp j ΔP represents the charge / discharge power margin; ΔP represents the lumped differential power; j represents the j-th electric vehicle charge / discharge event in the set of electric vehicle charge / discharge events at the current moment.

[0077] Therefore, the implementation of this application can be achieved by issuing corresponding power commands (i.e., charging and discharging power) through the control center. jThe system controls the charging pile corresponding to each electric vehicle charging / discharging event to charge the electric vehicle with the corresponding charging / discharging power. Specifically, it controls the target charging pile corresponding to each non-emergency charging / discharging event to charge the electric vehicle with the charging / discharging power, and controls the charging pile corresponding to each emergency charging / discharging event to charge the electric vehicle with the maximum charging power.

[0078] It is understood that the embodiments of this application only determine the charging and discharging power of electric vehicles based on the real-time information of the currently accessed electric vehicles and the aggregated power guidance curve. This is easy to implement and can significantly reduce the tracking error of the aggregated power guidance curve by electric vehicle aggregators in the real-time control stage, and reduce the charging and discharging power fluctuation of individual electric vehicles. In addition, the power decomposition rules of the embodiments of this application have a fast calculation speed and are suitable for real-time control of electric vehicle charging and discharging power in large-scale electric vehicle access scenarios.
