[0029] Figure 2 It is a flowchart of a push method for improving user enthusiasm for participating in a frequency modulation according to an embodiment of the present application.

[0030] like Figure 2 As shown, the method comprises the following steps:

[0031] Step S201, obtaining travel power consumption, target subsidy cost and loss reduction, wherein the travel power consumption is the estimated power consumption of the user's daily travel by electric vehicle, the target subsidy cost is the subsidy provided by the aggregator to the user for participating in a frequency modulation, and the loss reduction is the loss of the vehicle battery that is expected to be reduced by the user participating in a frequency modulation by using other travel modes;

[0032] Specifically, in the present application, it is taken into account that users participate in a frequency modulation to reduce the power consumption during the peak period of the power grid. The methods generally include replacing other modes of travel and adjusting the charging time of electric vehicles, both of which will bring inconvenience to users' travel. Therefore, when considering profits, it is necessary to consider the amount of electricity consumed by users during travel, that is, the above-mentioned travel electricity consumption, and the subsidies provided by aggregators to users, that is, the above-mentioned target subsidy fees, and then determine the reduction in battery loss caused by the user's reduced power consumption, and obtain the above-mentioned loss reduction.

[0033] Step S202, calculating a first cost increment and a first profit increment according to the above-mentioned travel electricity consumption, calculating the profit of the above-mentioned user according to the above-mentioned target subsidy fee, the above-mentioned first profit increment, the above-mentioned loss reduction and the above-mentioned first cost increment, and obtaining a first target profit, wherein the above-mentioned first cost increment is the estimated increase in travel cost of the above-mentioned user by participating in a frequency modulation by adopting other travel modes, and the above-mentioned first profit increment is the estimated reduction in charging cost of the above-mentioned user by participating in a frequency modulation by adopting other travel modes;

[0034] Specifically, when a user changes his travel mode to participate in a frequency modulation, considering that the user does not need to charge the electric car, the reduced charging cost is determined as the above-mentioned first profit increment and as a part of the above-mentioned first target profit, and the corresponding reduced battery loss is determined as another part of the first target profit, the above-mentioned target subsidy fee is determined as the last part of the first target profit, the cost of traveling by other means is determined as a part of the reduction in the above-mentioned first target profit, and the inconvenience caused by the user switching to other travel modes is converted into another part of the reduction in the above-mentioned first target profit through fitting.

[0035] Step S203, calculating a second cost increment and a second profit increment based on the above-mentioned travel electricity consumption, calculating the profit of the above-mentioned user based on the above-mentioned target subsidy fee, the above-mentioned second cost increment and the above-mentioned second profit increment, and obtaining a second target profit, wherein the above-mentioned second cost increment is the estimated increase in travel cost of the above-mentioned user when he / she uses an electric vehicle for travel and participates in a frequency modulation by adjusting the charging time, and the above-mentioned second profit increment is the estimated reduction in charging cost of the above-mentioned user when he / she uses an electric vehicle for travel and participates in a frequency modulation by adjusting the charging time;

[0036] Specifically, when a user changes the charging time of an electric vehicle to participate in a frequency modulation, considering that users have different charging times for their electric vehicles and the electricity price is relatively low, the reduced charging cost will be determined as the above-mentioned second profit increment and as a part of the above-mentioned second target profit. The above-mentioned target subsidy fee will be determined as the last part of the first target profit, and the inconvenience caused by the user's change of charging time to travel will be converted into a reduction in the above-mentioned first target profit through fitting.

[0037] Step S204, when the above-mentioned first target profit or the above-mentioned second target profit is greater than or equal to the first threshold, target push information is generated and pushed to the above-mentioned user at least based on the above-mentioned first target profit and the corresponding travel mode or based on the above-mentioned second target profit and the corresponding travel mode.

[0038] Specifically, the user's willingness to participate in a frequency modulation is evaluated through surveys and other means, and it is determined that when the profit is greater than a certain threshold, that is, the above-mentioned first threshold, the user tends to participate in the frequency modulation. Then, when the calculated first target profit or the above-mentioned second target profit is greater than or equal to the first threshold, the relevant information of the frequency modulation is pushed to the user to increase the user's enthusiasm for participating in the frequency modulation.

[0039] Through this embodiment, first, the travel electricity consumption, target subsidy cost and loss reduction amount are obtained, the above-mentioned travel electricity consumption is the estimated electricity consumption of the user's daily travel by electric vehicle, the above-mentioned target subsidy cost is the subsidy of the aggregator to the above-mentioned user for participating in a frequency modulation, and the above-mentioned loss reduction amount is the loss of the vehicle battery that is expected to be reduced by the above-mentioned user by participating in a frequency modulation by other travel modes; then, the first cost increment and the first profit increment are calculated according to the above-mentioned travel electricity consumption, and the profit of the above-mentioned user is calculated according to the above-mentioned target subsidy cost, the above-mentioned first profit increment, the above-mentioned loss reduction amount and the above-mentioned first cost increment to obtain the first target profit, the above-mentioned first cost increment is the travel cost that is expected to be increased by the above-mentioned user by participating in a frequency modulation by other travel modes, and the above-mentioned first profit increment is the The charging cost is expected to be reduced by the frequency modulation; then, the second cost increment and the second profit increment are calculated according to the above-mentioned travel electricity consumption, and the profit of the above-mentioned user is calculated according to the above-mentioned target subsidy fee, the above-mentioned second cost increment and the above-mentioned second profit increment, and the second target profit is obtained. The above-mentioned second cost increment is the travel cost expected to be increased by the above-mentioned user when he uses an electric car to travel and participates in the frequency modulation by adjusting the charging time, and the above-mentioned second profit increment is the charging cost expected to be reduced by the above-mentioned user when he uses an electric car to travel and participates in the frequency modulation by adjusting the charging time; finally, when the above-mentioned first target profit or the above-mentioned second target profit is greater than or equal to the first threshold, at least according to the above-mentioned first target profit and the corresponding travel mode or according to the above-mentioned second target profit and the corresponding travel mode, the target push information is generated and pushed to the above-mentioned user. This application considers different ways for users to participate in a frequency modulation, calculates the profit of users participating in a frequency modulation respectively, and pushes the relevant information of a frequency modulation to the user when any one of the participating ways brings the profit to the user greater than the preset value, so as to improve the user's enthusiasm for participating in a frequency modulation. This method solves the problem in the prior art that users do not understand the cost and benefits of participating in a frequency modulation, resulting in low enthusiasm for participating in a frequency modulation.

[0040] In order to obtain the first cost increment and the first profit increment, in an optional implementation, the step S202 includes:

[0041] Step S2021: Substitute the above travel power consumption into D q (i) = a i [W c (i)] 2 +b i W c (i) calculating the first cost increment mentioned above,

[0042] Among them, D q (i) is the first cost increment mentioned above, a i and b iis the fitting coefficient, W c (i) is the above travel electricity consumption, i is user i;

[0043] Specifically, in general, the utility function of user travel and the power consumption of the user travel are monotonically non-decreasing and convex functions. Therefore, the first cost increment of the user participating in the primary frequency modulation and the power consumption of the user travel are monotonically non-decreasing and concave functions, that is, the opportunity cost of the user increases, and the cost of user i can be represented by a quadratic function, as shown in the above formula. Among them, the fitting coefficient is a constant greater than 0, which is adjusted according to the historical data of user i participating in the primary frequency modulation.

[0044] Step S2022: Substitute the above travel power consumption into Calculate the first profit increment mentioned above,

[0045] Where, ΔD c (i) is the first profit increment mentioned above, C chg (λ(j)) is the charging service price in time period j.

[0046] Specifically, during peak electricity consumption periods, users can participate in primary frequency regulation by reducing load by using other modes of travel. The benefit of reducing electricity consumption is the charging cost of their original planned travel, which is calculated as shown above.

[0047] In order to calculate the first target profit, in an optional implementation, the step S202 further includes:

[0048] Step S2023: Substitute the target subsidy fee, the first profit increment, the loss reduction and the first cost increment into ΔD ag (i) = D b (i)+ΔD c (i)+D bat (i)-D q (i) Calculate the first target profit mentioned above,

[0049] Where, ΔD ag (i) is the first target profit mentioned above, D b (i) Subsidize the above-mentioned target, D bat (i) is the above loss reduction, ΔD c (i) is the first profit increment mentioned above, D q (i) is the first cost increment mentioned above.

[0050] Specifically, the above-mentioned target subsidy fee is taken as user profit, the above-mentioned first profit increment is converted as user profit, the above-mentioned loss reduction amount is taken as user profit and the above-mentioned first cost increment is taken as user expenditure, and the above-mentioned first target profit can be calculated according to the above formula.

[0051] In order to calculate the second cost increment and the second profit increment, in an optional implementation, the step S203 includes:

[0052] Step S2031: Substitute the above travel power consumption into D p (i) = β ct {a i [W c (i)] 2 +b i W c (i)} Calculate the second cost increment mentioned above,

[0053] Among them, D p (i) is the second cost increment mentioned above, β ct is the preset coefficient, a i and b i is the fitting coefficient, W c (i) is the above travel electricity consumption, i is user i;

[0054] Specifically, when a user participates in a frequency modulation by transferring the charging time, the user cost refers to the loss caused by the user changing the charging time. At this time, the impact on the user's travel demand is relatively small. This application determines the scaling factor between the second cost increment and the first cost increment by fitting historical data as β ct , then the second cost increment is as above.

[0055] Step S2032: Substitute the above travel power consumption into ΔD d (i) = D c (i)-D c '(i) Calculate the second profit increment mentioned above,

[0056] Where, ΔD d (i) is the second profit increment mentioned above, D' c (i) The charging cost before adjusting the charging time for the above user, D c (i) The charging cost after adjusting the charging time for the above user.

[0057] Specifically, when a user participates in a frequency modulation by transferring the charging time, the present application stipulates that the charging time before and after the transfer does not interfere with the user's travel electricity consumption. Then the change in the user's expenditure before and after participating in the frequency modulation, that is, the above-mentioned second profit increment is only related to the change in electricity price, and the above-mentioned second profit increment can be calculated according to the above formula.

[0058] In order to calculate the second target profit, in an optional implementation, the step S203 further includes:

[0059] Step S2033: Substitute the target subsidy fee, the second cost increment and the second profit increment into ΔD bg (i) = D b (i)+ΔD d (i)-D p (i) Calculate the above second target profit,

[0060] Where, ΔD bg (i) is the second target profit mentioned above, D b (i) is the target subsidy cost, ΔD d (i) is the second profit increment mentioned above, D q (i) is the first cost increment mentioned above, D p (i) is the second cost increment mentioned above.

[0061] Specifically, when the electricity consumption time is transferred to participate in a frequency modulation, since the total amount of charging remains unchanged, that is, it does not involve changes in battery loss, the above-mentioned target subsidy fee is taken as the user profit, the above-mentioned first profit increment is converted as the user profit and the above-mentioned first cost increment is taken as the user expenditure, and the above-mentioned second target profit can be calculated according to the above formula.

[0062] In order to calculate the above loss reduction, in an optional implementation, the above step S201 includes:

[0063] Step S2011, obtaining the battery purchase cost and battery cycle life, wherein the battery purchase cost is the cost of purchasing the vehicle-mounted battery, and the battery cycle life is the maximum number of charge and discharge cycles within the life cycle of the vehicle-mounted battery;

[0064] Specifically, each charging and discharging cycle will affect the life of the battery. Therefore, this application considers that when the user travels by other means, there is no need to charge or discharge, so the consumption of reducing the battery life is determined as the above loss reduction. Therefore, the battery purchase cost C is obtained bat , and battery cycle life N dis In one embodiment, the value of the battery cycle life is 1000.

[0065] Step S2012, calculating the ratio of the battery purchase cost to the battery cycle life to obtain the loss reduction amount.

[0066] Specifically, the battery purchase cost and the battery cycle life are substituted into That is, the above loss reduction is calculated.

[0067] In order to calculate the above travel power consumption, in an optional implementation, the above step S201 further includes:

[0068] Step S2012, obtaining a target power and a target duration, wherein the target power is the rated charging power of the vehicle-mounted battery, and the target duration is the estimated charging duration of the electric vehicle for daily travel;

[0069] Specifically, based on the user's travel history data, the user's daily charging time is estimated to obtain the above target time, and the rated power is determined according to the battery model to obtain the above target power.

[0155] Specifically, when a user changes his travel mode to participate in a frequency modulation, considering that the user does not need to charge the electric car, the reduced charging cost is determined as the above-mentioned first profit increment and as a part of the above-mentioned first target profit, and the corresponding reduced battery loss is determined as another part of the first target profit, the above-mentioned target subsidy fee is determined as the last part of the first target profit, the cost of traveling by other means is determined as a part of the reduction in the above-mentioned first target profit, and the inconvenience caused by the user switching to other travel modes is converted into another part of the reduction in the above-mentioned first target profit through fitting.

[0157] Specifically, when a user changes the charging time of an electric vehicle to participate in a frequency modulation, considering that users have different charging times for their electric vehicles and the electricity price is relatively low, the reduced charging cost will be determined as the above-mentioned second profit increment and as a part of the above-mentioned second target profit. The above-mentioned target subsidy fee will be determined as the last part of the first target profit, and the inconvenience caused by the user's change of charging time to travel will be converted into a reduction in the above-mentioned first target profit through fitting.

[0158] Step S204, when the above-mentioned first target profit or the above-mentioned second target profit is greater than or equal to the first threshold, target push information is generated and pushed to the above-mentioned user at least based on the above-mentioned first target profit and the corresponding travel mode or based on the above-mentioned second target profit and the corresponding travel mode.

[0159] Specifically, the user's willingness to participate in a frequency modulation is evaluated through surveys and other means, and it is determined that when the profit is greater than a certain threshold, that is, the above-mentioned first threshold, the user tends to participate in the frequency modulation. Then, when the calculated first target profit or the above-mentioned second target profit is greater than or equal to the first threshold, the relevant information of the frequency modulation is pushed to the user to increase the user's enthusiasm for participating in the frequency modulation.
