Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of an electricity price calculation method according to an embodiment of the present invention, which may be executed by an electricity price calculation apparatus, which may be implemented by software and/or hardware, and is generally configured in a primary station server. As shown in fig. 1, the method includes:
and 110, acquiring a power utilization request sent by a user terminal, analyzing the power utilization request to obtain power utilization time, power utilization starting time and the area where the user terminal is located, and determining the power utilization time period according to the power utilization starting time and the power utilization time period.
The master server is a server responsible for data processing. The user terminal is a mobile terminal such as a smart phone and a tablet computer, or a special mobile device. Fig. 2 is a block diagram of a dedicated mobile device according to an embodiment of the present invention. As shown in fig. 2, the dedicated mobile device 200 includes a microprocessor 210, a data protection unit 220 connected to the microprocessor 210, a display unit 230, a communication unit 240, a positioning unit 250, and a keyboard unit 260. The location unit 250 determines the location of the area where the user is located in order to further determine the number of the intelligent power supply terminal that the user needs to use. For example, the microprocessor 210 finds an intelligent power supply terminal within a certain range around according to the position of the mobile device, and acquires the number of the intelligent power supply terminal. The keyboard unit 260 allows a user to input an intelligent power supply terminal, a power utilization start time and a power utilization duration which need to be used according to the needs of the user, and then transmits the number of the intelligent power supply terminal, the power utilization start time and the power utilization duration to the master station server through the communication unit 240. The mobile device obtains the price of the electricity to be paid by the user transmitted by the master station server through the communication unit 240, and displays the price of the electricity to be paid by the user through the display unit. The data protection unit 220 is used for data protection in the whole process, and personal privacy and property security of the user are ensured. The microprocessor 210 is used to control the safe and orderly operation of the entire process.
Illustratively, the master station server obtains a power consumption request sent by the user terminal, where the power consumption request includes a number of the intelligent power supply terminal, a power consumption duration and a power consumption starting time. Because the main station server maintains the relation table between the intelligent power supply terminal and the region/position, the region where the user terminal is located can be determined according to the number of the intelligent power supply terminal. After the master station server obtains the power utilization request, the master station server analyzes the power utilization request to obtain the power utilization time length, the power utilization starting time and the area where the user terminal is located. And determining the electricity utilization termination time according to the electricity utilization starting time and the electricity utilization duration, and determining the electricity utilization time interval according to the electricity utilization starting time and the electricity utilization termination time.
And 120, acquiring historical real-time electricity prices corresponding to the electricity utilization periods in set days of the area where the user terminal is located, and calculating the average electricity price at each moment according to the historical real-time electricity prices corresponding to the electricity utilization periods.
The set number of days may be a default value set according to experience, and it may be set to different set numbers of days according to different application scenarios. In general, the set number of days may be one month or one week, or may be longer or shorter.
In the process that the user uses the shared power utilization system, the master station server stores real-time electricity prices and user power utilization data at all times, wherein the user power utilization data comprise power utilization data and power utilization amount. For example, the user electricity consumption data and the real-time electricity price at each moment are stored through the cloud server. After the master station server obtains the power utilization request, the cloud server is inquired according to the area where the user terminal is located and the power utilization time period, and historical real-time power price corresponding to the power utilization time period in the set number of days is obtained. And if the set days are 30 days, inquiring the cloud server according to the area where the user terminal is located and the power utilization period, and acquiring the historical real-time power price corresponding to the power utilization period of 30 days. Then, the average electricity rate at each time within the electricity consumption period is calculated from the average value of the historical real-time electricity rates at each time within the electricity consumption period of 30 days.
Optionally, the master station server stores the user electricity consumption data to the cloud server. In order to provide better service for the user, the user needs to be provided with the electric energy usage condition of the user at the shared power supply port every month when the user needs the electric energy usage condition, and more economical usage suggestions are recommended to the user according to the usage habits of the user. For example, 12:00 hours have many people using the power supply port, and the price of electricity is high; few people are used at 24:00, and the electricity price is relatively low; then, the user can be recommended to avoid the peak of electricity utilization, so that the power supply pressure during the peak of electricity utilization can be greatly relieved. Similarly, the power supply ports in different areas have different use conditions, and a more cost-effective charging area can be provided for the user according to the use habits of the user.
And step 130, predicting the electricity price to be paid by the user according to the average electricity price, and sending the electricity price to be paid by the user to the user terminal.
For example, the master station server may calculate the electricity price Y to be paid by the user using the following formula:
wherein, Y is the electricity price needed to be paid by the user, tmPower consumption starting time, t, requested by usernFor the power consumption termination time requested by the user,
is the first 30 days time tmThe average price of electricity at the time of day,
is the first 30 days time tnAverage electricity price in hours; n-m is tmTime tnThe total number of time periods divided between the time instants, assuming that the user 12:00 requests charging for half an hour, (n-m) is 30 since the real-time electricity rate is updated every minute.
After the intelligent power supply terminal supplies power to the electric equipment of the user requesting power utilization, the intelligent power supply terminal collects power consumption data and sends the power consumption data to the master station server according to a set period. The power consumption data refers to power consumption. And the intelligent power supply terminal reports the current power consumption data of each power supply port to the master station server every minute. Assuming that the electric energy of the power supply port a reported at 12:00 is 100kwh, and the electric energy of the power supply port a reported at 12:01 is 100.1kwh, it means that the power consumption of the power supply port a in one minute is 0.1kwh, i.e. the power consumption data of the power consumption port a is 0.1 kwh. The electricity charge that the user using port a needs to pay for this 1 minute is 0.1 times ρiWhere ρ isi12, calculated for the user when applying for using the power supply port: real-time electricity rates of 00 to 12:01 minutes. The master station server needs to store the real-time user electricity consumption data of each port in real time so as to determine the electricity fee to be paid by the user when the charging is finished.
The master station server acquires the shared power consumption used at each momentThe number of the electricity customers of the system and the number of the available power supply ports in the corresponding area adopt the following formula to calculate the real-time electricity price rho in the area under considerationi:
Where ρ isiIs the real-time electricity rate at time i,
is the price of the active power at the time i,
is the reactive power value at the time i, e is the comprehensive price-adjusting factor, KiFor adjusting the price factor in real time, MiFor investigating the number of requesting customers, N, in the area at time iiThe number of available power ports remaining in the area is considered for time i.
Through the formula, the master station server can calculate the real-time electricity price of the shared electricity consumption in a certain area at present and stores the real-time electricity price to the cloud server so as to calculate the electricity price to be paid by a user when the user uses the shared power supply port.
It should be noted that the generator is generally accompanied by the generation of reactive power while generating active power. Although the reactive power cannot work, the reactive power plays a very important role in stabilizing the system voltage, so that great attention is paid to the fact that some equipment such as a phase modulator in a power grid is specially used for emitting the reactive power to stabilize the voltage of the power grid, so that the current power fee comprises the power fee of active power and the power fee of reactive power. The active electricity price at the moment i and the reactive electricity price at the moment i are related to a plurality of factors such as the efficiency of the power generation equipment, the power generation amount, the transmission loss of a power grid and the like, the price is determined by a power supply bureau, and the power supply bureau can make adjustment sometimes.
The comprehensive price-adjusting factor is a macroscopic price-adjusting means formulated by companies developing shared electricity-using services according to the actual income conditions of the companies, the national electricity price policy, the analysis of supply-demand relations, the future service income expectation and other factors, and is generally formulated again every quarter.
Although the comprehensive price adjustment factor roughly determines the electricity price when sharing the electricity, the economic and cultural differences among different areas in the same city are large, so that although the comprehensive price adjustment factors determined in the same city are the same, the power supply port usage proportion of the shared electricity is greatly different. And the service conditions of the power supply ports in different periods of the same area are also greatly different. In view of these circumstances, the concept of real-time pacing factors has therefore been added. The company developing the shared electricity utilization service can finely adjust the price according to the difference of the use proportion of the power supply ports in different regions and different time periods, so that users are guided to use the power supply ports more evenly, the situation that one side is used in a bundled mode and the other side is not in need of extra attention is avoided, the power supply pressure can be reduced (the peak value of electricity utilization is reduced), and the income can be properly increased.
And realizing an electricity price elastic mechanism by integrating the price adjusting factors and the real-time price adjusting factors. The master station server can regulate and control the electricity utilization interval of the user and the selection of the electricity utilization place from the macroscopic aspect and the microscopic aspect, and the maximization of scientific power supply and electricity selling benefits is realized. For example, if the number of people using electricity in a certain time period is large, the real-time electricity price in the time period can be increased by adjusting the real-time price adjusting factor, so as to guide the user to use electricity in different time periods.
According to the technical scheme, the electricity price which needs to be paid by the user using the shared electricity utilization system is calculated through the historical real-time electricity price in a previous period, so that the user knows the electricity price which needs to be paid by the user using the shared electricity utilization system in a selected period in advance, the user is guided to reasonably adjust the electricity utilization time, and the pressure of a power grid is reduced.
Fig. 3 is a flowchart of another electricity price calculation method according to an embodiment of the present invention, as shown in fig. 3, the method includes:
And 303, predicting the electricity price to be paid by the user according to the average electricity price, and sending the electricity price to be paid by the user to the user terminal.
And after calculating the power price required to be paid by the user, the master station server generates an order according to the power price required to be paid by the user and sends the order to the user terminal. And after the user terminal receives the order, displaying the order of which the user needs to pay the electricity price through the display unit. And obtaining the operation information of the user for the order, and returning order determining information or order modifying information to the master station server according to the user operation information.
And step 304, if the order confirmation information sent by the user terminal is detected, sending a power supply command to the intelligent power supply terminal.
And the power supply command is used for indicating the intelligent power supply terminal to supply power to corresponding electric equipment in the power utilization time period.
For example, after receiving the order confirmation information sent by the user terminal, the master station server sends a power supply command to the intelligent power supply terminal selected by the user, so as to instruct the intelligent power supply terminal to supply power to the power supply port corresponding to the user within the power consumption period specified by the user.
And 305, acquiring user power consumption data sent by the intelligent power supply terminal according to a preset period.
The user electricity consumption data comprises electricity consumption data and electricity consumption amount. The preset period may be an artificial set value, and the specific value thereof is not specifically limited in the embodiment of the present invention.
After receiving the power supply command, the intelligent power supply terminal collects the voltage and current parameters of the electric equipment in real time and calculates the power consumption data of the user according to the voltage and current parameters. The intelligent power supply terminal calculates the real-time electricity consumption amount of the user according to the user electricity data and the real-time electricity price, stores the electricity consumption amount and the electricity consumption data as the user electricity consumption data in a local protection unit, and sends the user electricity consumption data to the master station server for backup.
Optionally, the intelligent power supply terminal performs alarm marking on newly acquired unreasonable data according to the stored historical power consumption data and the stored power consumption amount. For example, a threshold value can be added to the program of the intelligent power supply terminal to make a preliminary judgment on the reasonability of the data.
For example, after receiving the user power consumption data reported by the intelligent power supply terminal, the master station server performs correctness determination (or referred to as error determination) on the user power consumption data with the alarm identification information through an RANSAC algorithm. It should be noted that, there may be many algorithms for determining the correctness of the power consumption data of the user, and the embodiment of the present invention is not limited in particular. For example, K-means or Mean-Shift algorithms may also be used.
And 307, storing the electricity utilization data of the user to a cloud server.
And 308, acquiring the number of the remaining available power supply ports in the area corresponding to the intelligent power supply terminal at the current moment, and acquiring the number of the requested power consumption users in the area corresponding to the intelligent power supply terminal at the current moment.
And 309, determining the current real-time electricity price of the area corresponding to the intelligent power supply terminal according to the electricity consumption data, the number of available power supply ports and the number of requested electricity consumption users.
Here, the electricity consumption data is the electricity consumption data included in the user electricity consumption data determined by the master station server to be correct. And acquiring preset active power price, reactive power price, comprehensive price adjusting factors and real-time price adjusting factors, wherein the values of the comprehensive price adjusting factors and the real-time price adjusting factors are related to power consumption data. Determining an exponent number according to the real-time price adjusting factor, the number of the users requesting power utilization and the number of available power supply ports, and calculating a power operation result of the comprehensive price adjusting factor according to the exponent number; and determining the current real-time electricity price of the corresponding area of the intelligent power supply terminal according to the active electricity price, the reactive electricity price and the power operation result.
The real-time electricity price of a certain area at a certain time can be calculated by adopting the following formula:
where ρ isiIs the real-time electricity rate at time i,
is the price of the active power at the time i,
is the reactive power value at the time i, e is the comprehensive price-adjusting factor, KiFor adjusting the price factor in real time, MiNumber of clients requesting electricity at time i, NiThe number of available power ports remaining in the area is considered for time i.
Assuming that the current moment is No. 13:00 of No. 16 of 4 months, the real-time electricity price calculated according to the number of the remaining available power supply ports in the investigation region at 13:00 and the number of the clients requesting electricity utilization, the active electricity price, the reactive electricity price, the comprehensive price adjusting factor, the real-time price adjusting factor and other parameters in the investigation region at 13:00 is stored in the master station server. The real-time electricity rate is not used today, but is used when the user pays the real-time electricity rate for the next 13:00 hours in a week or even a month to calculate the average value.
And 310, sending the real-time electricity price to the intelligent power supply terminal so as to indicate the intelligent power supply terminal to calculate the electricity consumption amount based on the real-time electricity price.
It should be noted that the master station server returns the calculated real-time electricity price to the intelligent power supply terminal, and processes the user electricity consumption data of the next intelligent power supply terminal after receiving the confirmation receipt information replied by the intelligent power supply terminal.
And 311, eliminating wrong user electricity utilization data from the obtained user electricity utilization data.
The technical scheme of the embodiment of the invention can realize the function of real-time electricity metering, and gives the electricity price to be paid by the user needing to use the shared electricity utilization system according to the existing information such as the real-time electricity price, so that the user not only knows how much electricity is used by the user, but also knows the electricity price to be paid by the user using the shared electricity utilization system in the period in advance, thereby reasonably adjusting the service time and reducing the pressure of a power grid. Meanwhile, through an electricity price elastic mechanism, the master station server can regulate and control the electricity utilization interval of the user and the selection of the electricity utilization place from the macroscopic aspect and the microscopic aspect, and the maximization of scientific power supply and electricity selling benefits is realized. Meanwhile, the electricity consumption data of the user are locally stored in the intelligent power supply terminal and are synchronized to the cloud server, and high safety of the data is guaranteed.
