Problems solved by technology

[0003] In the initial stage of electricity market construction, market rules will inevitably be continuously revised and improved with the problems that arise in the market development; at the same time, the power grid structure, power supply structure, and economic level of each province are quite different. Whether the market model and rules will face the above questions can no longer be answered through human experience. Considering the huge cost of trial and error in the market, it cannot be tested through the actual effect of market operations; Factors such as structure, congestion resolution, supply and demand situation, and policy conditions are also constantly changing. The bidding behavior of electricity sales companies is also adjusted with the external market environment. It is difficult to predict the adaptability of their behavior to market rules only through theoretical analysis.
[0004] The operation of the electricity market is a long-term dynamic evolution process, and the market behavior of electricity sales companies is also constantly adjusted. It is difficult to predict the operation effect of the market only through theoretical analysis

Embodiment 1

[0064] Based on the above-mentioned method for simulating market behavior of electricity sales companies in direct transactions of power users, a market behavior simulation system for electricity sales companies in direct transactions of power users is constructed:

[0065] Including basic data preparation module, transaction case creation module, market member declaration parameter setting module, simulation control module, transaction case analysis module, a total of five parts.

[0066] 1. The basic data preparation module is used to set the basic simulation data of the overall market environment. This module supports the direct import of desensitized actual transaction operation system data, which is convenient for the trading center to carry out market operation simulation and rule verification. Including electricity sales company management module, generator management module, transaction type management module, market access management module. The granularity of the mar...

Embodiment 2

[0112] The present invention provides a method for simulating the market behavior of electricity sales companies in direct transactions of electric power users, which includes the following steps:

[0113] Step 1. Set the basic parameters of the simulation case. Including the market supply and demand ratio, the number of power generators, the number of electricity sellers, the quotation type of market members, and the parameters of market members themselves.

[0114] Step 2. Initialize the simulation data. According to the set trading rounds, set all rounds of declaration data to be written into the declaration form; according to the quotation range of market members, initialize the declaration strategy set, selection probability (1 / number of strategies), and selection tendency based on the intelligent agent method.

[0115] Step 3. Proxy declaration. Calculate the probability interval corresponding to each strategy selection probability, generate a (0,1) random number, dete...

Embodiment 3

[0128] The present invention also provides a market behavior simulation system for electricity sales companies in direct transactions of electric power users, including:

[0129] The transaction case creation module is used to set up the simulation scene case set;

[0130] The market member declaration parameter setting module is used to set the initial condition set of the market member, the learning strategy set of the market member, the maximum simulation round T and quotation data;

[0131] The simulation simulation control module is used to carry out simulation simulation according to the simulation simulation scene case set, market member initial condition set, market member learning strategy set, initial selection tendency, maximum simulation round T and quotation data;

[0132] The transaction case simulation analysis module is used to analyze and display the case transaction simulation results of the simulation simulation by the simulation control module.

[0133] Am...

Abstract

The invention discloses an electricity selling company market behavior simulation method and system in power consumer direct transaction, and the system comprises: a basic data preparation module which is used for setting basic simulation data; a transaction case creation module which is used for creating a simulation case scene; a market member declaration parameter setting module which is used for setting market member quotation modes and declaration parameters; an analog simulation control module which is used for carrying out analog simulation according to the set basic simulation data, the created simulation case scene, the market member quotation mode and the declaration parameters; and a transaction case simulation analysis module which is used for analyzing and displaying a case transaction simulation result of analog simulation performed by the analog simulation control module. According to the invention, the trial and error cost of power market construction is reduced, the verification means of market rules is enriched, the behavior simulation of the power selling company closer to the actual operation and production environment is realized, and the technical support is provided for the market behavior of the power selling company in the direct transaction of power consumers.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, and in particular relates to a method and system for simulating market behavior of electricity sales companies in direct transactions of electric power users. Background technique [0002] In the electricity sales market, the provincial electricity wholesale market organizes direct transactions between large power users and power generation companies; as a new type of market entity, electricity sales companies have developed rapidly in recent years, and by virtue of their professionalism and flexibility, they have become wholesale market power users. The main force on the side. Electricity sales companies usually participate in the market in the form of agents, and the contract consists of retail contracts signed with agent users and wholesale electricity purchase contracts signed with power generation companies. With the changes in the market environment, market rules, and the de...
