and S40, sending the electricity utilization feedback information to a user terminal so that a user can pay and adjust electricity utilization requirements and electricity utilization behaviors according to the electricity utilization feedback information.
The intelligent power supply method in the embodiment of the present invention may be applied to the intelligent power supply management system 100 shown in fig. 2. Specifically, the intelligent power supply management system 100 includes a management center 110 and a management terminal 120.
The management terminal 120 is installed in the electricity utilization place of the user, connected to an electricity meter of the electricity utilization place and connected to the electricity utilization equipment in the electricity utilization place, and the management terminal 120 controls the on/off of the electricity utilization equipment and counts the electricity consumption of different electricity utilization equipment or electricity utilization loops.
The management center 110 is connected to the electric power market trading center, and acquires trading data and remaining untrammeled electric quantity of the electric power market trading center at preset time intervals. The transaction data is current and future electric power transaction data and historical transaction data.
In the intelligent power supply method in the embodiment of the present invention, the preset time period may be one day, three days, one week, or other time periods. The transaction data of the electric power market transaction center comprises current and future electric power transaction data and historical transaction data.
The first electric power transaction curve is formed according to first electric power transaction data, the first electric power transaction data is electric power transaction data which is obtained by the management center from transaction data of the electric power market transaction center, and the time corresponding to the selected electric power purchase comprises the preset time period or is positioned in the preset time period.
The remaining capacity curve is obtained by subtracting the first power transaction curve from the generated capacity curve.
And newly-added electric power transaction data is predicted to be newly-added electric power transaction data in a future preset time period by the management center according to weather forecast, holiday information, current economic environment, whether power grid transformation is carried out or not and the like in the preset time period, which can influence the electric power consumption and electric power transaction, in the historical transaction data of the electric power market transaction center, on the basis of the traded electric quantity, and the time period in which similar information exists in the historical transaction curve is obtained. It can be understood that, because the electric power purchased by the user has a certain continuity, the user may purchase more electric power after having purchased a certain amount of electric power, due to factors such as weather forecast, holiday and festival information, current economic environment, whether the power grid is modified, and the like, so as to meet the power consumption demand of the user. At this time, the user may trade the newly increased power amount with the power market trading center again. Therefore, when the power consumption requirement and the power consumption behavior of the user are considered, dynamically added power transaction data need to be predicted, so that the power feedback result is more accurate. Of course, the newly added transaction electric quantity of the user in the future preset time period can be predicted through the historical transaction curve, so that newly added electric power transaction data in the future preset time period can be predicted.
And combining the residual capacity curve and the newly added electric power transaction data to further obtain the spare capacity and further obtain a spare capacity curve, wherein the spare capacity curve is the predicted capacity which is not purchased or used in the electric power wholesale market.
And after the spare electric quantity curve is obtained, whether the spare electric quantity value of the user meets the power utilization standard is further judged. Supposing that the electricity utilization standard is X kilowatt-hour in the peak period of electricity utilization, if the vacant electric quantity value of the user at a certain time exceeds X kilowatt-hour, the electricity utilization standard is met, and if the vacant electric quantity value of the user at a certain time does not exceed X kilowatt-hour, the electricity utilization standard is not met. It is understood that the electricity utilization standard in the present embodiment may be determined according to the national energy saving policy.
In the embodiment of the invention, firstly, a residual capacity curve in a future preset time period is determined through a power generation capacity curve and a first power transaction curve in the future preset time period; then newly added electric power transaction data in the future preset time period are predicted through historical transaction data of the electric power market transaction center, and a spare electric quantity curve is obtained; on the basis of the electricity utilization standard, determining the comparison condition of the user spare electricity value in the future preset time period and the electricity utilization standard according to the spare electricity curve, so as to judge whether the user spare electricity value at any moment in the future preset time period reaches the electricity utilization standard or not, and generating corresponding electricity utilization feedback information according to the judgment result; and finally, feeding back the electricity utilization feedback information to a user terminal so that a user can pay fees and adjust electricity utilization requirements and electricity utilization behaviors according to the electricity utilization feedback information. Therefore, a user can know whether the power consumption requirement and the power consumption behavior of the user accord with the energy-saving policy through the user terminal, so that the national energy-saving policy is responded positively, and the problems of contradiction between power supply and demand, power consumption pressure and the like are relieved.
In a specific embodiment, in step S10, a remaining power curve is obtained according to a power generation capacity curve of a future preset time period and a first power transaction curve of the future preset time period, specifically:
s11, determining the generating capacity of the future preset time period according to a generating plan or historical power transaction data of a power plant, and forming a generating capacity curve according to the generating capacity;
s12, screening out first electric power transaction data from historical transaction data of the electric power market transaction center, and forming a first electric power transaction curve according to the first electric power transaction data; wherein the time corresponding to the purchased electric power comprises the future preset time period or data within the future preset time period;
and S13, subtracting the first power transaction curve from the power generation capacity curve to obtain a residual power curve.
It is understood that the management center 110 may determine the power generation capacity for a future preset time period through the power generation plan of the power plant or the historical trading data with the power market trading center; of course, the management center 110 may also obtain historical trading data with the power plant from the electric power market trading center, and further obtain the power generation capacity for the future preset time period.
The first power transaction data includes two parts, wherein one part covers the future preset time period for the power time purchased by the user, and the other part is positioned in the future preset time period for the power time purchased by the user. Taking a preset time period of a quarter as an example, the a subscriber purchases power for the entire quarter, and the B subscriber purchases power for one month of the entire quarter, so the first power transaction data includes not only the a subscriber's power transaction data but also the B subscriber's power transaction data.
The remaining capacity is the capacity which is not purchased in the electric power wholesale market in the future preset time period and can be obtained by subtracting the first electric power transaction data from the generated capacity.
In a specific embodiment, in step S20, new electricity trading data in the future preset time period is predicted according to historical trading data of the electricity market trading center, and a free electricity curve is obtained according to the new electricity trading data and the remaining electricity curve, specifically:
s21, second electric power transaction data with the transaction time difference smaller than the preset time and the time difference corresponding to the purchased electric power are obtained from the historical transaction data of the electric power market transaction center, and a second electric power transaction curve is formed according to the second electric power transaction data;
s22, predicting newly added power transaction data through the second power transaction curve; the newly increased power trading data is used for predicting the newly increased power used in the future preset time period for the power market trading center;
s23, subtracting the newly increased power transaction data from the remaining power curve to obtain a spare power curve; wherein the free electricity curve is a predicted electric capacity that is not purchased or used in the electric power wholesale market.
In the embodiment of the present invention, the management center 110 may obtain the electricity transaction data (referred to as second electricity transaction data in this embodiment) with a time close to the time corresponding to the purchased electricity through the historical transaction data of the electricity market transaction center, form a second electricity transaction curve according to the second electricity transaction data, predict the newly added electricity transaction data according to the second electricity transaction curve, and further obtain the empty electricity quantity curve. Through the vacant electric quantity curve, the vacant electric quantity value of each user in the future preset time period can be known, and then the electricity utilization standard is combined, whether the electricity utilization requirement and the electricity utilization behavior of each user accord with the national energy-saving policy is judged, so that the user can pay fees and adjust the electricity utilization requirement and the electricity utilization behavior according to the electricity utilization feedback information.
Of course, the newly added electric power transaction data in the future preset time period can be further predicted by combining the information that the electricity consumption and the electric power transaction can be influenced by weather forecast, holiday information, current economic environment, whether the power grid is modified and the like in the preset time period and the time period of obtaining similar information in the historical transaction curve.
Taking the preset time as one month as an example, assuming that the time corresponding to the electric power purchased by the user is 9 months to 12 months in 2020, half year time is counted, and the electric power in each month is quantified. Through historical transaction data of the electricity market transaction center, electricity transaction data of 7-8 months in 2020 can be obtained, so that electricity purchased by a user in 7-8 months in 2020 is determined, meanwhile, electricity utilization requirements and electricity utilization behaviors of the user before time corresponding to the purchased electricity can be known, and further, newly-added electricity transaction data of 9-12 months in 2020 is predicted.
Although the electric power purchased by the user has a certain continuity, the prediction still has errors, so weather forecast, holiday information, current economic environment, whether power grid transformation exists or not in 9-12 months in 2020 can be combined with information which can influence electricity utilization and electricity transaction, for example, in 11-12 months in 2020, more electricity needs to be added due to heating requirements, and thus, the newly added electricity transaction data in 9-12 months in 2020 can be accurately predicted.
In a specific embodiment, in step S30, a determination result of the vacant electric quantity value and the electricity consumption standard of the user in the future preset time period is determined from the vacant electric quantity curve, and corresponding electricity consumption feedback information is generated according to the determination result, specifically:
s31, according to the vacant electric quantity curve, determining a first time period in which the vacant electric quantity value of each user is smaller than a first preset value and a second time period in which the vacant electric quantity value of each user is larger than a second preset value; wherein the first preset value is smaller than the second preset value;
s32, determining the electricity price increase of the first time period according to the difference value between the vacant electric quantity value corresponding to each first time period and the first preset value;
s33, determining electricity price rewards of the second time periods according to the difference value between the vacant electric quantity values corresponding to the second time periods and the second preset value;
and S34, generating corresponding electricity utilization feedback information according to the first time period, the corresponding electricity price increase, the second time period and the corresponding electricity price reward.
In the current reward policy, most rewards only set a fixed reward rate, are difficult to adjust according to the power load condition, and are difficult to mobilize the enthusiasm of users for saving electricity.
In this embodiment, the more the electricity consumption saved by the user is, the higher the corresponding electricity price reward is, in other words, the larger the difference between the vacant electricity value of the user and the second preset value is, the higher the electricity price reward corresponding to each electricity price used by the user in the second time period is, and the electricity price reward can be used for offsetting part of the electricity prices, so that the user can pay less electricity charges.
Specifically, the first preset value and the second preset value are both preset two spare electric quantity threshold values, wherein the first preset value is smaller than the second preset value. When the vacant electric quantity value of the user is smaller than the first preset value, the vacant electric quantity value of the user is less, the energy-saving policy is not met, and the electricity price can be increased adaptively; when the vacant electric quantity value of the user is larger than the second preset value, the vacant electric quantity of the user is more, the energy-saving policy is met, and electricity price reward can be provided adaptively.
In this embodiment, through the empty power curve, a time period (referred to as a second time period in this embodiment) in which the empty power value of each user is greater than the second preset value may be determined, and a difference between the two time periods may be calculated. Of course, it is also possible to determine a time period in which the vacant electric quantity value of each user is smaller than the first preset value (referred to as the first time period in this embodiment), and calculate a difference value between the two.
And then determining electricity price reward of the second time period according to the difference value between the vacant electricity quantity value corresponding to each second time period and the second preset value, and predicting the electricity price = balanced electricity price-reward electricity price so as to reward the user to actively respond to the energy-saving policy in the second time period.
In addition, the electricity price increase of the first time period is determined according to the difference value between the vacant electricity quantity value corresponding to each first time period and the first preset value, and then the electricity price = the balance electricity price + the increased electricity price of the first time period is predicted to promote the power generation of the power generation party. Wherein the increased electricity price may be equal to the electricity price reward or determined according to the second time period newly purchased electricity amount predicted by the electricity price reward.
Therefore, the embodiment of the invention can adjust the electricity price according to the power load condition, particularly determine the electricity price reward and the increase of the electricity price through the vacant electricity quantity curve, feed back electricity utilization feedback information to the user, encourage the user to further respond to an energy-saving policy and promote the power generation of a power generation party, and further effectively realize the balance of power supply and demand, reduce the electricity utilization pressure and improve the conforming curve.
In a specific embodiment, in step S40, the sending the electricity consumption feedback information to a user terminal specifically includes:
and sending power utilization feedback information containing the second time period and the power price reward to a user terminal.
After the power utilization feedback information is sent to the user terminal, the method further comprises the following steps:
and sending power utilization feedback information containing the first time period and the power price increase to a power plant.
In this embodiment, the management terminal 120 sends the information to the user and the power plant through various methods, including public number push, short message, and other methods.
