Description
Technical Field
The invention relates to the field of energy utilization, in particular to a method and a system for setting electricity price.
Background
With the increasing severity of environmental problems and the increasing exhaustion of fossil energy, clean, safe, efficient and sustainable energy systems are increasingly the goals pursued by various countries, and renewable energy will become an important component in future energy structures of various countries. In the coming energy internet era, demand-side response is an important approach to enhance power system stability, increase renewable energy utilization, and achieve open collaboration of energy power systems.
Scholars at home and abroad have made intensive research on demand side response methods. As the demand-side response method, there are mainly incentive-based and electricity rate-based demand-side response methods. The incentive-based demand side response compensates the loss of the user caused by load shedding at the peak time or system fault, and then encourages the user to shed the load; the demand side response based on the electricity price is that different electricity prices are provided for the user at different moments, and the electricity price information is taken as a reference, so that the user can actively reduce the electricity consumption when the electricity price is high, and further reduce the electricity consumption demand at the peak moment.
Incentive-based demand-side responses include direct load control, interruptible load, load bidding and buyback, and emergency load shedding. The direct load control means that the direct load control actuator controls the start-stop state of part of the power equipment of the user through the remote control device at the peak time of the system, and the participating users can obtain corresponding interruption compensation of loss caused by the control. The interruptible load is characterized in that according to a contract signed by a supplier and a supplier in advance, an interruptible load implementing mechanism sends an interrupt request signal to a user in a power grid peak period, and the user can be compensated for the interruption of partial power supply after the user responds. The load bidding and the repurchase refer to that at the peak moment, if a user reduces the power load, the user can obtain the income at a special bidding price according to the saved electric energy. Emergency load shedding refers to when the demand power in the grid exceeds its stored power, users will be given incentive compensation to make up for their loss caused by shedding load in an emergency.
Because the stimulated demand side response only starts a mechanism when a problem occurs, the electricity pressure can be only locally relieved, and the problem of electricity imbalance cannot be fundamentally solved.
The electricity prices are different in different time periods of time-of-use electricity prices, so that electricity consumption peaks in low electricity prices can be caused, and artificial peak loads are generated. The regulation effect of the peak electricity price on the load is too limited; and the peak interest rate is difficult to set, the user dissatisfaction (some devices cannot avoid the peak time and need to bear high electricity price) can be caused by the overhigh peak interest rate, and the effect of reducing the load can not be achieved by the overlow interest rate. It is also difficult to fully realize the real-time electricity rates due to technical limitations on the demand side.
Therefore, how to set the electricity price so as to guide the user to reasonably use the electricity is a problem that needs to be solved currently.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses an electricity price pricing method, which is shown in figure 1 and comprises the following steps:
step S11: and acquiring the energy consumption of the user in a time period in a preset period to obtain an energy consumption set.
Specifically, the corresponding energy consumption of the user in each time period in the preset cycle is obtained, so that an energy consumption set including the energy consumption of all the time periods in the whole preset cycle is obtained.
For example, the preset period may be one day, the daily formation may be divided into T periods, T may be 24, the index thereof is denoted by T ∈ T ═ 1, 2.. times, T }, the user may be denoted by i ∈ N ═ 1, 2.. times, N }, for any user i, i ∈ N, N denotes a natural number, and the energy consumption vector of the user may be expressed as:in the formula,representing the energy consumption of the user i at the moment t; assume that any user i has the lowest energy consumption:in the formula,represents the lowest energy consumption, which represents the energy consumption that guarantees the user's basic life needs, while user i also requires a highest energy consumption:in the formula,the maximum energy consumption is expressed, and the formula represents the upper limit of energy consumption for the user i to reach a comfortable living standard.
In actual life, a user can freely change the starting and stopping time of part of electric equipment in a family. In embodiments of the present invention, it is contemplated that the user may also adjust their total energy consumption, such as by using alternate devices or adjusting the power usage of the powered device to change the energy consumption.
Step S12: and calculating the energy consumption electricity price component of the user in a preset period by using the energy consumption set.
Specifically, after the energy consumption set is obtained, the energy consumption set can be multiplied by a preset energy consumption parameter, so that the energy consumption electricity price component of the user in a preset period is calculated, the energy consumption electricity price component and the electricity consumption of the user in the preset period are in a direct proportion relation, and the electricity price is higher along with the increase of the electricity consumption in the period.
For example, the energy consumption set is 10, the energy consumption parameter is 0.01, and the energy consumption electricity price component in the preset period is 1 after the two are multiplied.
Step S13: and calculating the following electricity price component of the user in a preset period by using the charging standard in the preset charging standard set corresponding to the time interval and the energy consumption corresponding to the time interval.
Specifically, because the grid load is also divided into a high-load time period and a low-load time period, the time period in the preset period can be divided into a plurality of levels of time periods according to the grid load condition, the preset charging standard of each time period is different, and corresponding adjustment is performed according to different charging standards of energy consumption in the same time period, so that the charging standard of each time period corresponds to the corresponding energy consumption, and calculation is performed respectively to obtain the following electricity price component of the user in the preset period.
Step S14: and calculating the periodic electricity price by using the energy consumption electricity price component and the following electricity price component.
Specifically, the periodic electricity price is obtained by adding the energy consumption electricity price component and the following electricity price component together, and the electricity price of the user in the preset period can be accurately expressed.
Step S15: and calculating the comprehensive benefit of the user by utilizing the periodic electricity price, the energy consumption set and the preset user demand degree in the user demand degree set corresponding to the unit time period in the preset period so as to be used for adjusting the electricity utilization behavior of the user.
In particular, in order to guarantee the user's personal interests, it is necessary to guarantee the user's satisfaction level with the power service. In the embodiment of the invention, the satisfaction degree of the user is related to the demand degree and the electricity consumption of the electric energy. The demand degree of the electric energy mainly reflects the urgency degree of a user for electric power service in a certain time period, and the electricity consumption reflects the electric quantity required by the user to meet the demand.
In the embodiment of the invention, the demand degree of the user i for the electric energy in each time period in the preset period can be usedTo indicate that the user is not in a normal position,the willingness of the user i to pay for the power service at the moment t can be reflected; then, useIndicating that user i consumes at time tThe satisfaction of the electrical quantity, wherein,at least the following three conditions should be satisfied: function(s)The electric energy consumption is not decreased, more work can be completed when more electric energy is used by a user, and the satisfaction degree of the electric energy consumption is naturally improved; the marginal benefit of the user satisfaction degree is non-incremental, and the satisfaction degree of the unit electric energy obtained by the user is gradually reduced along with the increase of the energy consumption; when the power consumed by the user is zero, the satisfaction degree is also zero, and when the user does not use the power, the satisfaction degree obtained by the consumed power is zero.
If the demand degree of the user i is NiWith an energy consumption of qiPaying a power consumption fee of piThen the combined benefit over the preset period can be expressed as:
further, the comprehensive benefit of the user can be calculated by using the periodic electricity price, the energy consumption amount and the user demand amount in the preset period corresponding to the user demand amount set in the unit time period, the user adjusts the electricity consumption behavior of the user by the periodic electricity price and the comprehensive benefit, that is, adjusts the electricity consumption amount in different time periods, so that the periodic electricity price and the comprehensive benefit reach the self-expected value, and the adjustment of the electricity consumption behavior is completed, the user can circularly execute the steps S11 to S15 until the maximum comprehensive benefit of the user is obtained, for example, after the first comprehensive benefit of the user is calculated in the step S15, the user adjusts the corresponding electricity consumption behavior by using the calculated first comprehensive benefit, so that the first energy consumption amount in the time period in the preset period is obtained, and then the first energy consumption amount is substituted into the step S11 until the step S15, so that the second comprehensive benefit is calculated, and the user adjusts the corresponding power utilization behavior according to the calculated second comprehensive benefit to obtain second energy consumption in a time period within the preset period, substitutes the second energy consumption into the step S11 until the step S15, and continuously circulates until the maximum comprehensive benefit of the user is calculated.
Therefore, the invention calculates the energy consumption and electricity price component of the user in the preset period by acquiring the energy consumption set of the user in the preset period, calculates the following electricity price component of the user in the preset period by using the preset charging standard corresponding to the time interval and the energy consumption corresponding to the time interval, calculates the period electricity price by using the energy consumption and electricity price component, and finally calculates the comprehensive benefit of the user by using the period electricity price, the energy consumption set and the preset user demand concentrated in the user demand concentrated corresponding to the unit time interval in the preset period, so that the user can obtain the maximum comprehensive benefit by using the electricity consumption of different electricity behaviors, and the user can select the future electricity behaviors by using the electricity consumption and the electricity behaviors corresponding to the maximum comprehensive benefit, thereby achieving the maximum benefit of the user.
The embodiment of the invention discloses a specific electricity price setting method, and compared with the previous embodiment, the embodiment further explains and optimizes the technical scheme. Specifically, the method comprises the following steps:
step S21: acquiring the energy consumption of a user in a time period within a preset period to obtain an energy consumption set;
step S22: and calculating the energy consumption electricity price component of the user in a preset period by using the energy consumption set.
Specifically, calculating the energy consumption electricity price component of the user in a preset period by using an energy consumption set and an energy consumption electricity price component calculation formula; wherein,
the calculation formula of the energy consumption electricity price component is as follows:
in the formula, priieRepresenting the energy consumption price component, d representing the preset energy consumption parameter, e representing the energy consumption priceComponent peak value, qi tRepresents the energy consumption of the user i in the period T, and T represents T periods in the preset period.
It can be understood that the electricity price cannot be arbitrarily priced for adjusting the electricity consumption behavior of the user, and therefore, the electricity price is maintained at a preset value after exceeding a certain limit, and therefore, the peak value e of the energy consumption electricity price component is preset, and when the value calculated by the energy consumption electricity price component through the energy consumption parameters and the energy consumption amount set exceeds the peak value of the energy consumption electricity price component, the peak value of the energy consumption electricity price component is taken as the energy consumption electricity price component. For example, the energy consumption parameter may be 0.015, the peak value of the energy consumption electricity price component may be 0.5, the preset period may be one day, and T may be 24.
Step S23: and calculating the following electricity price component of the user in a preset period by using the charging standard in the preset charging standard set corresponding to the time interval and the energy consumption corresponding to the time interval.
Specifically, step S23 may specifically include step S231 to step S233; wherein,
step S231: and judging whether the fluctuation degree of the electric load of the user exceeds a preset fluctuation range or not by using the energy consumption corresponding to the time interval.
In practical application, the power consumption of a user may not fluctuate greatly, the power consumption is kept stable in a preset period, and the fluctuation may also fluctuate violently, different calculation modes can be selected according to whether the fluctuation degree of the power consumption load of the user exceeds a preset fluctuation range, so that the following power price component is obtained, and therefore, the calculation mode of the following power price component is determined by judging whether the fluctuation degree of the power consumption load of the user exceeds the preset fluctuation range by utilizing the energy consumption corresponding to a time interval. For example, the preset range may be set to 0.7.
Step S232: if the following power price component does not exceed the preset following power price component constant value, the following power price component is a preset following power price component constant value;
specifically, if the fluctuation degree of the power load of the user does not exceed the preset fluctuation range, the following power rate component is a preset following power rate component constant value, and since the fluctuation degree of the power load of the user is not large, the power load can be regarded as constant-power utilization, and a fixed value is given to the following power rate component, that is, the preset following power rate component constant value, for example, the preset following power rate component constant value may be 0.7.
Step S233: and if the following electricity price component is exceeded, calculating the following electricity price component by using the charging standard in the charging standard set and the energy consumption corresponding to the time interval.
In the embodiment of the invention, the whole power utilization period can be divided into three power utilization levels, namely a high power utilization level, a medium power utilization level and a low power utilization level according to a predicted power grid load curve, and the power distribution energy level of a power grid is represented;
(1) in the electricity utilization in the advanced period, the higher the electricity consumption is, the higher the unit electricity utilization cost in the period is;
(2) in the electricity utilization in the 'intermediate period', the higher the electricity consumption is, the higher the unit electricity utilization cost in the period is, and the unit electricity utilization cost in the period is lower than the unit electricity utilization cost in the 'advanced period' under the condition of the same electricity consumption;
(3) in the "low-level period" of electricity usage, the higher the amount of electricity usage, the lower the unit electricity usage cost of the period, and the higher the amount of electricity usage in the period, the higher the total cost.
For example, in the "advanced period", electricity is used at 10 degrees, the electricity rate per degree is 2 yuan, electricity at 50 degrees, and the electricity rate per degree is 5 yuan; in the middle stage time period, the electricity is used, 10 degrees of electricity are used, the electricity fee per degree is 1 yuan, 50 degrees of electricity are used, and the electricity fee per degree is 2 yuan; in the advanced period, the electricity is used, 10 degrees of electricity is used, the electricity fee per degree is 0.5 yuan, 50 degrees of electricity is used, and the electricity fee per degree is 0.25 yuan.
Specifically, if the fluctuation degree of the power load of the user exceeds the preset fluctuation range, the following power rate component is calculated by using the charging standard in the charging standard set and the energy consumption corresponding to the time interval, wherein the specific process of calculating the following power rate component may include steps S2331 to S2333; wherein,
step S2331: and averaging by using the charging standard in the charging standard set and the energy consumption corresponding to the time interval, and calculating the initial following electricity price component.
Specifically, because the charging standards of different time periods and different energy consumptions are different, the charging standard of the same time period and the energy consumption of the same time period are calculated to obtain sub-initial following electricity price components of a plurality of time periods, and then the sub-initial following electricity price components of the plurality of time periods are averaged to obtain the initial following electricity price components.
Step S2332: and judging whether the initial following electricity price component exceeds a preset following electricity price component threshold value.
