Problems solved by technology

[0003] At present, the Cournot model or the Bertrand model is generally used to analyze the game process of the electricity market, but the Cournot model will result in high monopoly and low social benefits. Different oligopolies have the same market status, which is inconsistent with real market competition

Embodiment Construction

[0062] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0063] Such as figure 1 As shown, according to the relevant documents of the central government on electricity reform and the local plans on the construction of the electricity market, a structural diagram of the relevant electricity market can be constructed. It includes the power generation side composed of traditional power generator X and multiple micro-grids, the transmission and distribution side composed of power grid companies, dispatching agencies, power trading centers, etc., and the user side composed of electricity sales companies and market users.

[0064] A Cournot-Bertrand hybrid model of distribution market with the participation of microgrids, constructing a duopoly Cournot-Bertrand model:

[0065] The power suppliers in a distribution area include traditional power generator X and microgrid operator Y,

[0066] In the electricity mar...

Abstract

The invention discloses a power distribution market Cournot-Bertrand hybrid model under participation of a micro-grid, and relates to the technical field of power distribution market model analysis under participation of the micro-grid. The power distribution market Cournot-Bertrand hybrid model comprises the following steps: firstly, proposing a Cournot-Bertrand model, and establishing a Duopolyand a triopoly Cournot-Bertrand model; and analyzing a Nash equilibrium solution and a system local stability domain, and comparing power supply quantity and electricity price relations to analyze different oligopoly gaming models. The invention proposes a power distribution market oligopoly and triopoly Cournot-Bertrand dynamic gaming model under participation of a micro-grid: a traditional powergeneration group is responsible for maintaining market supply, takes the power supply quantity as a decision variable to form a Cournot model, and takes the price as a decision variable to form a Bernoulli model in order to enhance the market competitiveness of the micro-grid. According to the power distribution market Cournot-Bertrand hybrid model, the asymmetry of the micro-grid and the traditional power generation group in market competition is considered, and the constructed Cournot-Bertrand model provides a more balanced competition mode for the power market.

Description

technical field [0001] The invention relates to the technical field of model analysis of a power distribution market participated by a microgrid. Background technique [0002] Large capital investment in power operation, economies of scale and other characteristics determine that the power market is an oligopoly market. The traditional power generation group is the main supplier in the market, and the microgrid is affected by reliability and has a small market share. The main players in the market are microgrids and traditional power generation groups on the power generation side, and electricity sales companies and market users on the user side. The characteristics of the power industry, such as economies of scale and high technical requirements, determine that under the power reform, the power market is still an oligopolistic market. Microgrids and traditional power generation groups are representative oligopolistic enterprises in the electricity market, supplying power ...
