Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, specific embodiments thereof are described in detail.
The first embodiment is as follows:
the present embodiments provide a method for managing demand response of an electric vehicle, comprising: s10, acquiring position information, running direction and residual electric quantity information of the electric vehicle; s20, calculating and determining a first distance from the electric vehicle to the charging pile through the position information; s301 the first determination condition includes: judging whether the residual electric quantity information is in a preset electric quantity range or not; s302 the second determination condition includes: judging whether the first distance is greater than a first preset value; s303 the third determination condition includes: judging whether the running direction meets a first preset direction or not; when the first determination condition, the second determination condition, and the third determination condition are all determined to be yes, S40 transmits a request for a demand response to the electric vehicle.
In this embodiment, referring to fig. 1, it is described how to accurately send a signal of a demand response request to an electric vehicle in a coverage area of the demand response request on the premise that the electric vehicles can receive the signal of the demand response request.
The electric power department company can generate a demand response signal through the central server to initiate a request for a demand response event, the central server can transmit the demand response signal to the server in the control device, the control device can be arranged in the charging pile, and the demand response signal is sent to the electric vehicle capable of participating in the demand response event through the server. Similarly, the electric vehicle may receive the request signal of the demand response event by using the application software installed in the vehicle or the mobile phone application software corresponding to the electric vehicle, and the user may select to accept or reject the request of the demand response event. In this embodiment, the position information of the electric vehicle needs to be acquired first, and a value of a first distance from the electric vehicle to the charging pile is calculated through the position information, where the first distance is specifically a length value, and the first preset value is a factory default value of the control device, and the first preset value can be set according to an actual application environment, so that the selection of the first preset value is more suitable for road traffic conditions of a coverage area.
In the first determination condition, the remaining power information of the electric vehicle needs to be acquired to determine whether the remaining power of the electric vehicle is within a preset power range, the preset power range is also a factory default, and the electric vehicle can be set and selected by a user so that the preset power range better conforms to a specific implementation scene. The preset electric quantity range is a specific range of electric quantity, and has an upper limit value and a lower limit value, and whether the residual electric quantity information is in the preset electric quantity range is judged, wherein the preset electric quantity range includes the upper limit value and the lower limit value, that is, when the residual electric quantity of the electric vehicle is the upper limit value or the lower limit value of the preset electric quantity range, the judgment condition that the residual electric quantity is in the preset electric quantity range is met.
Further, the third determination condition includes that whether the running direction of the electric vehicle meets a first preset direction is determined, and similarly, the first preset direction is a factory preset value and can be selected and set by a user, so that the first preset direction better conforms to a specific implementation scene. When the running direction of the vehicle is obvious and the vehicle runs in the direction far away from the charging pile, namely the electric vehicle is judged to have no charging intention at the moment, the third judgment condition is not met at the moment.
The electric vehicle in this embodiment needs to satisfy the first determination condition, the second determination condition, and the third determination condition at the same time, that is, when all three determination conditions need to be combined to determine yes, the corresponding electric vehicle only satisfies a signal capable of receiving the demand response request sent by the server at this time, so that a user group capable of receiving the signal of the demand response request can be further accurately determined, a signal for sending the demand response request to a user who does not satisfy the qualification is reduced, a traffic jam situation caused by the fact that the user who does not satisfy the qualification accepts the demand response request is reduced, and meanwhile, an influence of the user on a trip due to the fact that the user accepts the demand response request is reduced.
Example two:
specifically, referring to fig. 2, the step S301 of determining whether the remaining power information is in the preset power range includes: s3001, judging whether the residual electric quantity information is in a first preset range; if yes, S3011 determines the first determination condition as yes; if not, the step S3012 is executed to continuously determine whether the remaining power information is within a second preset range; if the residual electric quantity information is out of the second preset range; the process proceeds to step S3021 where the first determination condition is determined as no; if the residual electric quantity information is in a second preset range; step S3022 is executed to obtain a charging record of the electric vehicle, and a line graph of a charging rule of the electric vehicle is fitted through the charging record; controlling the judgment result of the first judgment condition according to the charging rule; wherein the value of the second preset range is lower than the value of the first preset range.
In this embodiment, the preset electric quantity range includes a first preset range and a second preset range, and a lower limit of the first preset range is equal to an upper limit of the second preset range, where the first preset range is a closed interval, and the second preset range is an open interval, that is, when the remaining electric quantity information is at the lower limit of the first preset range, the determination condition that the remaining electric quantity information is in the first preset range is still satisfied, that is, the first determination condition is determined as yes.
When the remaining power information does not meet the first preset range, whether the remaining power information meets a second preset range or not is continuously judged, the second preset range is an alert power range relative to the first preset range, at the moment, a charging record of the electric vehicle is called by the server, specifically, a dotted broken line graph of a charging rule of the electric vehicle can be fitted according to the charging record, and therefore whether the electric vehicle meets a first judgment condition or not in the current demand response event is judged, and whether a user has qualification to participate in the demand response event or not can be accurately determined.
Meanwhile, in the present embodiment, the first preset range is preferably a 20% to 65% electric quantity range (closed interval), and the second preset range is preferably a 10% to 20% (open interval), wherein when the remaining electric quantity information is out of the second preset range, it indicates that the electric quantity of the electric vehicle is too low or too high, and the first determination condition is not satisfied. Specifically, if the remaining capacity of the electric vehicle is too low, the user must select to charge the electric vehicle, otherwise the electric vehicle of the user cannot be used normally, if a signal of a request for a demand response event is sent to such a user, if a part of the users select to participate in the demand response event for rewarding after the demand response event, the electric vehicle of the user cannot be used continuously, and therefore road traffic and the route planning of the user are affected.
If the electric quantity of the electric vehicle is too high and is higher than the upper limit value of the first preset range, it is indicated that the electric quantity of the electric vehicle is relatively sufficient and stable at the moment and subsequent use of the electric vehicle is not influenced, therefore, the electric quantity of the electric vehicle does not meet the first judgment condition at the moment, the server does not send a signal of a request of a demand response event to the user, so that the user who does not need to be charged can be prevented from participating in the demand response event to gain a profit, and the pressure of subsequent power output of a power grid is reduced.
Example three:
referring to fig. 2, controlling the determination result of the first determination condition according to the line graph of the charging law includes: step S3031, judging whether the electric vehicle has a charging habit in the current response time period according to the charging rule; if it is determined that the electric vehicle has a charging habit within the current response time period, the first determination condition is determined as no in step S3042; if it is determined that the electric vehicle does not have the charging habit in the current response period, the first determination condition of step S3041 is determined as yes.
In this embodiment, with reference to the second embodiment, the demand response event is a continuous process, and therefore, it is determined whether the electric vehicle has a charging habit in the current time period of the demand response event through the fitted dotted line graph of the charging rule, and when the electric vehicle has the charging habit in the current time period of the demand response event, it indicates that the user has a vehicle demand in the next duration, so that on the premise of not affecting the vehicle consumption experience of the user and not affecting the user's trip, for the user in the current time period of the demand response event, the determination result of the first determination condition is negative, that is, the part of the users currently does not satisfy the qualification for receiving the signal of the demand response event.
If the current time period of the demand response event is within the time period of the demand response event, the user does not have the charging habit, that is, the charging habit of the user is in the rest time period, and the user mostly has no vehicle demand in the next time period at this time, so the charging habit of the user is generally in the rest time period, therefore, when the electric vehicle of the user is within the second preset range, the first determination condition is still met, that is, the first determination condition is determined to be yes, the user has the qualification of receiving the signal of the demand response event, and meanwhile, because the request of the demand response event is bidirectional, when the user has a special condition in the next time, the user can be refused to participate in the demand response event, so that the journey of the subsequent user is not influenced, and therefore, the method in the embodiment can more accurately determine the user having the qualification of participating in the demand response event.
Example four:
whether the charging habit is possessed or not includes: whether the number of charges of the electric vehicle satisfies a second preset value within one unit of the response time period.
In the present embodiment, referring to fig. 3, a dotted line graph fitted by a charging law, the abscissa represents a time period in units of h (time), and the ordinate represents a charging number in units of: next, the process is repeated. Taking fig. 3 as an example, the charging time period of the electric vehicle is divided by the duration time period of the demand response event, in this embodiment, the charging time period is divided by 2 hours, and in the actual operation process, the charging time period can be set according to the actual situation. The charging times of the electric vehicle in the previous allowable storage period and distributed in each time period in one day are acquired, preferably, the allowable storage period in the present embodiment is preferably two months, that is, the charging times of the electric vehicle in each time period in one day in the last two months are acquired, where as can be seen from fig. 3, the electric vehicle in the present embodiment has eight charging records in the last two months, where the charging times have four times in 18 hours to 20 hours, two times in 14 hours to 16 hours, one time in 6 hours to 8 hours, and one time in 22 hours to 24 hours.
Therefore, in this embodiment, the second preset value is also a factory preset value, and can be set by itself according to the actual operating condition, wherein the second preset value in this embodiment is preferably three, one unit. Therefore, when the time period during which the demand response event lasts is within 18 th to 20 th, the number of times the electric vehicle is charged in this time period is four, so that the electric vehicle has a charging habit during the time period during which the demand response event currently lasts, and therefore the electric vehicle does not satisfy the first determination condition, the server will not send the signal of the demand response event to the user terminal.
If the time period of the continuous demand response time is within 6 hours to 8 hours, the number of times of charging the electric vehicle in this time period is one, so that the electric vehicle does not have a charging habit in the continuous time period of the current demand response event, and therefore the electric vehicle satisfies the first determination condition.
Example five:
forming an X axis of a coordinate system by using the linear distance from the electric vehicle to the charging pile, and taking the direction from the electric vehicle to the charging pile as the positive direction of the X axis; the first preset direction includes: the positive direction of the X-axis and the direction deviating from the first angle alpha on the basis of the positive direction of the X-axis.
In this embodiment, a linear distance from the electric vehicle to the charging pile forms an X-axis, wherein the charging pile is the closest charging pile to the linear distance of the electric vehicle. Wherein, the direction of filling electric pile by electric vehicle is the positive direction of X axle, and first preset direction is the preset direction of leaving the factory equally, can adjust the setting by oneself according to operating condition. In this embodiment, referring to fig. 4, the first predetermined direction is specifically a direction range, wherein specifically, the first predetermined direction is mainly the positive direction of the X axis, and a direction deviating from the first angle α from the positive direction of the X axis is also included in the first predetermined direction, and the deviated first angle α is also set by itself according to specific working conditions, but the first angle α may not exceed 180 degrees, that is, based on the positive direction of the X axis, the first boundary direction and the second boundary direction are two boundary directions of the first predetermined direction, and are used for defining the range of the first predetermined direction, wherein the first boundary direction extends toward the upper direction, the second boundary direction extends toward the lower direction, a first angle α is formed between the first boundary direction and the second boundary direction, and similarly, a sum of the angle from the first boundary direction to the X axis and the angle from the second boundary direction to the X axis forms the first angle α, and the angle from the first boundary direction to the X axis may not exceed 90 degrees, and similarly, the angle from the second boundary direction to the positive direction does not exceed 90 degrees. Preferably, in the present embodiment, the first angle α is preferably 90 degrees, that is, an angle between the first boundary direction and the positive X-axis direction is preferably 45 degrees, and an angle between the second boundary direction and the positive X-axis direction is preferably 45 degrees.
When the running direction of the electric vehicle is within the range of the first preset direction, namely the electric vehicle runs towards the charging pile, namely the electric vehicle has a certain charging intention, and the electric vehicle meets a third judgment condition. And if the running direction of the electric vehicle is not in the range of the first preset direction, the electric vehicle does not meet the third judgment condition at the moment. Therefore, the method in the embodiment can more accurately determine the users qualified to participate in the demand response time.
Further, detecting the running time of the electric vehicle, wherein the running time meets the first preset direction in one unit time; calculating a first proportion of the travel time in unit time; judging whether the first occupation ratio is larger than or equal to a first preset occupation ratio or not; if the judgment result is yes, the running direction meets a first preset direction; if not, the running direction does not meet the first preset direction.
It should be noted that, since the electric vehicle is continuously moving during the driving process, it is necessary to continuously detect the driving time of the electric vehicle meeting the first preset direction, and similarly, the unit time and the first preset proportion can be set by itself according to the actual situation, preferably, in this embodiment, the unit time takes a value of 20 minutes, the driving time of the electric vehicle meeting the first preset direction within 20 minutes is obtained, and the first proportion of the driving time within the unit time is calculated, wherein the influence on the driving direction caused by the road condition can be effectively reduced by appropriately lengthening the unit time. Preferably, in the present embodiment, the first predetermined proportion is preferably 60%, that is, if the electric vehicle has a travel time of 12 minutes within 20 minutes and is within the first predetermined direction, the third determination condition is satisfied at this time. Therefore, when the electric vehicle has a change in the traveling direction only at a certain time point or within a short period of time, the third determination condition will not be satisfied, and therefore the method in this embodiment can further reduce the erroneous determination of the third determination condition.
Example six:
