Problems solved by technology

[0003] The existing electricity sales company has a simple method of calculating the price of electricity sold by users, and only discounts the current price. However, in fact, the electricity sales company’s purchase cost varies from hour to hour in a day. The current price of electricity The model cannot reflect this cost-time difference, cannot provide users with price signals at different levels for each hour, and cannot guide users to change their electricity consumption behaviors so as to use electricity reasonably. The means of competition, because it directly squeezes the profit margin, is also unsustainable for the long-term interests of electricity sales companies

Embodiment 1

[0057] seefigure 1 It is a schematic flowchart of a real-time electricity price pricing method provided by Embodiment 1 of the present invention, the method includes the following steps:

[0058] S11. Determine the objective function of the real-time electricity price model of the electricity sales company;

[0059] In the electricity market, electricity sales companies are the main body of market competition, and profit is an important purpose for them to pursue. Here, the model puts the profit and competition strategy of the enterprise on guiding users to replace other forms of energy with electric energy through price, guiding users to use more electricity during low-peak periods to tap user consumption capacity during low-peak periods, etc. By optimizing the load curve, electricity retail companies can reduce electricity purchase costs, long-term investment costs and ancillary service fees, and increase market share, thereby gaining long-term benefits and development. The...

Embodiment 2

[0067] Referring to embodiment one of the present invention and figure 1 The specific process of steps S11 to S13 described in, figure 2 Corresponding to Embodiment 2 of the present invention figure 1 A schematic flow chart of a method for determining an objective function in S11, wherein step S11 specifically includes:

[0068] S111. Calculate the electricity sales revenue R' of the electricity sales company for one day, wherein, In the formula, L(n) is the real-time load of the nth period of the day, P n is the real-time electricity price value of the nth period of the day;

[0069] S112. Calculate the electricity sales cost C' of the electricity sales company for one day, wherein, In the formula, L(n) is the real-time load of the nth period of the day, C n It is the sum of the power purchase price and the transmission and distribution price of the nth period of the day;

[0070] S113. Calculate the daily profit π' of the electricity sales company, where π'=R'-C'; ...

Embodiment 3

[0098] Corresponding to the real-time electricity price pricing method disclosed in the first and second embodiments of the present invention, the third embodiment of the present invention also provides a real-time electricity price pricing device, see image 3 , the device consists of:

[0099] The first acquisition module 1 is used to determine the objective function of the real-time electricity price model of the electricity sales company;

[0100] The second acquisition module 2 is used to acquire the constraints of the real-time electricity price model of the electricity sales company;

[0101] The calculation module 3 is configured to establish the real-time electricity price model according to the objective function and the constraint conditions, and solve the real-time electricity price model to calculate and obtain a real-time electricity value.

[0102] Preferably, the first acquisition module 1 includes:

[0103] The first calculation unit 11 is used to calculate ...

Abstract

The present invention discloses a pricing method and device for real-time electricity prices. The method includes: determining the objective function of the real-time electricity price model of the electricity selling company; obtaining the constraint conditions of the real-time electricity price model of the electricity selling company; according to the objective function and the Constraint conditions establish the real-time electricity price model, and solve the real-time electricity price model to calculate the real-time electricity value. Realize the purpose of electricity sales companies to obtain benefits and guide users' electricity consumption behavior.

Description

technical field [0001] The invention relates to the technical field of sales electricity price pricing, in particular to a pricing method and device for real-time electricity prices of electricity sales companies. Background technique [0002] At present, in the document "Several Opinions on Further Deepening the Reform of the Electric Power System", it is pointed out that "the reform of the electricity sales side will be steadily promoted, and the electricity sales business will be released to social capital in an orderly manner." With the promulgation of this document, electricity sales companies have gradually increase. Some electricity sales companies purchase electricity in the electricity wholesale market through the electricity trading platform, and then resell it to the users they represent, and realize profits by earning enough price difference. With the increase of electricity sales companies, since power products are of the same nature to users, price will be the...
