Problems solved by technology

[0003] At home and abroad, there have been a large number of researches on the bidding strategies of various types of power generators in various types of markets. However, in view of this emerging market-oriented bidding model for biased electricity, the current domestic bidding strategies for power generators in this area are still incomplete. little research

Embodiment Construction

[0060] In order to better understand the purpose, technical solution and technical effect of the present invention, the present invention will be further explained below in conjunction with the accompanying drawings.

[0061] According to the present invention, based on the pre-listed monthly balance mode, the power supplier quotation decision-making method, its implementation process can adopt the following detailed steps, such as figure 1 Shown:

[0062] Step 1. Generate samples of unbalanced electricity.

[0063] Unbalanced electricity reflects the uncertainty of system prediction, which is described by probability density function (PDF). Assuming the actual total power consumption of the system Satisfied with the actual total planned electricity Normal distribution for the mean. Then the unbalanced power of the system can be calculated by the following formula:

[0064]

[0065] To simulate its uncertainty, the Sampling is performed K times, resulting in K rand...

Abstract

The invention discloses a bidding decision method of a power generation company based on a pre-listing monthly balance mode, which is fully based on the characteristics of the pre-listing monthly balance deviation processing mode, weighs the income and the risk of the power generation company, and considers the unbalanced power quantity of the system and the uncertainty of an opponent's bidding. The benefit function of a generation company in the up-down market can give consideration to both the profit and risk of the generation company in the deviated market. Through the probability functionand the equivalence curve, the unbalanced electricity quantity and the uncertainty of rival bidding can be described accurately. On the one hand, the model can provide certain reference for the bidding based on the pre-listed monthly balance deviation processing mechanism, and maximize the economic benefits of the generator and the system. On the other hand, the invention can provide a basis for the study of the market behavior of power generation companies.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a method for decision-making of a power supplier's quotation based on a pre-listed monthly balance method. Background technique [0002] In recent years, with the enlargement of market trading volume, the processing mechanism of deviation electricity will also play a vital role. my country has not yet established a power spot market balance mechanism to solve the problem of biased electricity caused by inaccurate system load forecasting and other reasons. A reasonable deviation handling mechanism is of great significance to the balance and stability of the system, reducing the pressure on the dispatching agency, that is, alleviating the contradictions between various market entities. According to the recommendation of the "Basic Rules for Mid- and Long-term Electric Power Transactions" (Interim), the implementation deviation of medium and long-term contracts is mainly adjusted by ad...
